As I write this report, we are getting ready for the 31st meeting of the IETF to be held in San Jose, California from December 5-9, 1994, and by the time the Internet Monthly Report is distributed, the word will be out that this was the largest meeting ever. Over 900 people have pre-registered for this meeting, and I anticipate breaking the 1000 attendee mark. The IETF meetings for 1995 have firmed up. The IETF will be meeting in Danvers, Massachusetts (a suburb of Boston) from April 3-7, 1995. The summer IETF meeting will be held in Stockholm, Sweden the week of July 17-21, 1995. Due to the costs to be incurred, the IETF attendance fee for the Stockholm meeting will be US$300. The final meeting for 1995 will be held in Dallas, Texas. While contracts have not yet been signed, it looks like the meeting will be December 4-8, 1995. Once all the arrangements have been made, notifications will be sent to the IETF Announcement list. Remember that information on future IETF meetings can be always be found in the file 0mtg-sites.txt which is located on the IETF shadow directories. This information can also be viewed from the IETF Home Page on the Web. The URL is: http://www.ietf.cnri.reston.va.us 2. The minutes of the IESG teleconferences have been publicly available on the IETF Shadow directories since 1991. These files are placed in the /ftp/iesg directory. The following IESG minutes have been added: October 20, 1994 (iesg.94-10-20) November 3, 1994 (iesg.94-11-03) 3.

Mark Knopper (mak@aads.net) Cooper [Page 11] Internet Monthly Report November 1994 ANSNET BACKBONE ENGINEERING REPORT ---------------------------------- Network Status Summary ======================= ANSnet total packet traffic increased by about 5.28% in November '94. An increase in the ANSnet forwarding table size of 3.29% was observed during the month of November. August Backbone Traffic Statistics ================================== The total inbound packet count for the ANSnet (measured using SNMP interface counters) was 90,014,646,313 on T3 ENSS interfaces, up 5.28% from October. The total packet count into the network including all ENSS serial interfaces was 100,925,726,278 up 4.83% from October. Router Forwarding Table Statistics ================================== The maximum number of destinations announced to ANSnet during November was 19,507 up 3.29% from October. The number of network destinations configured for announcement to the ANSnet but never announced (silent nets) during November was 20,294. BGP-4/CIDR Deployment Status ============================ As of December 1st '94, we have observed the withdrawal of 9,671 class based destinations from the ANSnet router forwarding tables that are now represented by 2,246 configured aggregates. Among these configured aggregates: 1,643 of these are top-level aggregates (not nested in another aggregate). 1,309 of these are actively announced to ANSnet. 898 of these have at least one subnet configured (the other 411 may be saving the Internet future subnet announcements). Cooper [Page 12] Internet Monthly Report November 1994 771 of these have resulted in the withdrawal of at least one configured more specific route. 759 of these have resulted in the withdrawal of 50% of their configured more specific routes. 701 of these have resulted in the withdrawal of most (80%+) of their more specific routes. For up-to-date information is available from merit.edu: pub/nsfnet/cidr/cidr_savings. For further details on these CIDR aggregates, see merit.edu:pub/nsfnet/cidr/nestings.announced for full listings. Routing Stability Measured on the T3 Network ============================================ Internal routing stability measurements are made by monitoring short term disconnect times (disconnects of five minutes duration or less). This is intended as a measure of overall system stability rather than complete connectivity. The greatest instability in November was contributed by a single T1 ENSS node on November 1st due to a faulty circuit. The problem circuit was an Ameritech leg of a T1 tail circuit provisioned through MCI which turned out to be a bad smartjack at the customer premise. This caused a very high level of packet loss. There were other problems, most notably an FDDI problem at the Hayward POP.

A lengthy T1 ENSS212 outage contributed about 5 hours of instability to the November data (which was excluded below). If this node is excluded from the data, very little instability in the other nodes is evident. ENSS136 experienced about 45 minutes of instability due to gated problem. CNSS32 experienced 36 minutes of instability due to high routing load on a machine with 32 MB of memory (memory upgrade still pending). ENSS213 and ENSS142 had just over 15 minutes of instability. All others had under 15 minutes of instability over the course of the month (>99.97% stable).

This storage will permit us to support a local copy of the AIDS Patent Database we described in the October IMR. It also provides the storage we need to support the latest version of Archie on our primary server (ds0.internic.net), and it has now been installed. Cooper [Page 18] Internet Monthly Report November 1994 As noted in the August IMR when we put the new Archie up on one of our backup servers, the new version supports searches for Gopher menu items as well as anonymous FTP file names. To search Archie for Gopher menu items, Gopher to ds0.internic.net or ds1.internic.net, and select "InterNIC Directory and Database Services" (item 4), "Search Anonymous FTP Site and Gopher Menu Indices using Archie" (item 8), and then "Gopher Index" (item 3). At that point, you might want to start with item 8 "Things you should know" and continue through item 13 to get an idea of how to use the system. If you do not have a Gopher client of your own, you can telnet to ds0.internic.net or ds1.internic.net, log in as gopher, and follow the same steps. We will install the new Archie on our third server once additional disk storage has been installed. A reminder - if you would like to help the Internet community find a resource that you offer, send mail to admin@ds.internic.net and we will send information about listing your resource in the Directory of Directories. by Rick Huber INTERNIC REGISTRATION SERVICES Progress Report for period November 1, 1994 through November 30, 1994 I.

Focus this month has been centered primarily upon the model desired for ownership and access of a Network Virtual Device (NVD). Since this project is interfacing devices directly to the Internet, questions of booting, ownership and access control arise in a new context. Device ownership is straightforward when a device is controlled via the system bus. The bus master, usually the CPU, owns the device and controls it exclusively, by means of a memory-mapped commands issued by device driver. But if a device is instead interfaced and controlled via a gigabit network, its commands must come across the network as packets, with any host able to send it packets. A de-facto emulation of the bus control methodology used today is possible. That is, an NVD could restrict its acceptable commands to only those sent from a specific Owner host, which corresponds to the CPU as bus master, with the Owner's address stored in the NVD as non-volatile memory. The Owner could send memory read/write commands as packets to the device. That model of access and control would be a nearly direct substitution of a network for the system bus, and as long as latency was sufficiently low, it would work. However, it incorporates constraints that are no longer necessary nor desirable in a network-based architecture. In a bus-based architecture, a device and its Owner are physically connected. Ownership is explicit. For an NVD, the Owner is not necessarily physically connected. Ownership can be both dynamic and freely determined. The Owner of an NVD does not control it directly via memory read/write, but indirectly, by means of packet exchange. The device driver must be split between the Owner and the NVD, with a protocol for access and control well-understood between them. After evaluating a number of alternative ownership-association strategies, we have tentatively adopted the following model for ownership. When an NVD is operating and accessible it will have one "Owner". That owner may be either the NVD itself, a general Cooper [Page 21] Internet Monthly Report November 1994 NVD Manager (NVDM) process, or some owning process at another Internet host. An Owner is responsible for controlling access to any NVD that it owns. The Owner is responsible for processing and filtering NVD access-request messages and either granting or denying access to the NVD. An NVD is inaccessible for use until its ownership has been established. When an NVD is inaccessible, it immediately discards all incoming messages except those required to maintain link-layer connectivity. When an NVD boots, it determines its default ownership and passes ownership to its Default Owner. The Default Owner will be either itself or its NVDM. If its NVDM is inaccessible, the NVD remains inaccessible until it can establish contact and pass ownership to its NVDM. Each NVD must have memory that stores it ownership status and the Internet address of its Owner. Filtering Access Requests Assume that the location of an NVD has already been determined by an external process that wishes access to that NVD. Obtaining access to an NVD is a four-stage procedure. (1) An access-request message is sent directly to the target NVD by the process that wishes to access that NVD. (2) The NVD forwards that message to its Owner. (3) The Owner then filters the access-request and either decides to grant it or deny access. It builds a reply and sends that reply back to the target NVD. (4) The target NVD creates from that reply a message that it sends back to the source of the original access-request message. If the Owner is not the NVD itself, the Internet address or name of the Owner is not sent in the reply. In the case that the target NVD owns itself, steps (2) and (3) are performed by the target NVD itself. The access-requesting process must implement a reasonable time-out in the event that no reply is received before it may re-request access to the same target NVD. That time-out MUST NOT be shorter than 5 seconds. Cooper [Page 22] Internet Monthly Report November 1994 No restriction is placed upon the filtering function execution other than that a reply message be sent back to the requesting process in a timely manner. An upper limit of 1 second to complete this procedure is suggested. Owner Failure If an NVD's Owner fails (halts, crashes, or reboots), that Owner loses ownership of that NVD. Discovery of this by the owned NVDs will occur in one of two ways: (1) The NVD expects a response from its owner and receives none within a mutually-agreed time limit. The NVD will reassert its default ownership. (2) An access-request message arrives at a target NVD. This message must be forwarded to the NVD's Owner. An access-request message must be replied to in a timely manner. Failure to reply in a timely manner results in the target NVD reasserting its default ownership. In the event that an Owner fails, the first subsequent access- request message will provoke a default ownership reponse from the target NVD. Successive access-request messages that arrive at the target NVD will then be forwarded to the target's new Owner, which will normally result in a response message. The intent is that the assertion of default ownership implies that the NVD also "reset" itself, so that particular internal hardware resources that are dedicated to a previous owner are made available to the new owner. This will often be equivalent to the state that an NVD was in just after it successfully booted. NVD Failure When an NVD itself fails, no response to repeated access-request messages will be received. This is distinct from failure to be granted access by an Owner, which results in the generation of explicit access-failure return messages. Greg Finn , S.K. Reddy Monnangi, , Vivek Goyal Cooper [Page 23] Internet Monthly Report November 1994 PC-ATOMIC --------- We have completed the PC-ATOMIC prototype card, a i486 VL-Bus (VESA) interface for the MyriCom LANai processor and network interface. The card was developed to provide an interface to the MyriNet network for low-cost i486-based hosts. The board has been tested as compatible with the link-level of the SBus Myricom interfaces. Overview (full text available on ftp://ftp.isi.edu/pub/hpcc-papers/touch/pca_overview.txt) PC-ATOMIC is a i486 VL-bus (VESA, Video-Local) interface to the links of Myricom's implementation of the ATOMIC LAN. It requires one full-length slot in a 33-Mhz 1-waitstate motherboard. It provides a bidirectional 640-Mbps (80 Mbytes/sec, byte-wide) channel over Myricom links, and is link-compatible with Myricom's Sun SPARC SBus interface. Small quantities of the board are available from ISI as GFE for research purposes. The specifications and design of the board are also available. The PC-ATOMIC interface uses a 16-bit LANai 1.2 host interface processor, and provides 128 Kbytes of dual-access RAM (emulates dual-ported RAM). The PC-ATOMIC board is memory-mapped, providing access to the RAM and memory-mapped registers. The registers provide: Internet checksum accumulates all PIO reads, writes can be reset to 0 via a register bit Disable/enable Internet checksum Board reset LANai reset-and-hold/release (for programming) LANai hardware interrupt signal to host The board also will support DMA in a future firmware release. This document refers to information from Myricom regarding their Sun SPARC 2.x host interface cards, LANai 1.2 programming information, and cable information. Contact Myricom for information on these items. Cooper [Page 24] Internet Monthly Report November 1994 The VL-side of the board runs at 33 Mhz (from the VL-Bus). The LANai has two sides - one runs off the on-board link clock, the other runs at a rate compatible with the host. Because the current LANai 1.2 is limited to host-side clocks of 25 Mhz or less, its host-side is clocked at 1/2 the VL-Bus clock. The board can be reprogrammed if a 33 Mhz LANai 1.2 becomes available. The board also contains a LANai 1.2 subsystem, nearly identical to that of the Myricom 1.2 Sun SPARC SBus prototype cards. The PC- ATOMIC board is link-level compatible with the Myricom LANai 2.0 SBus interfaces. The LANai uses a separate on-board crystal for the link clocking, independent of the LANai host-side clocking. This crystal is set to 40 Mhz for compatibility with current Myricom host interfaces and switches. Other crystals can be used, so long as BOTH ENDS OF EACH LINK use the same crystal frequency, as per the Myricom literature. Ted Faber , Annette DeSchon , Hong Xu , Joe Touch Mike Gorman , Jeff LaCoss ATOMIC-2 -------- The ATOMIC-2 project extends the results of the ATOMIC project, which developed a LAN from supercomputer chips. ATOMIC-2 is implementing an ATOMIC-ATM IP-level gateway to extend ATOMIC beyond LAN boundaries. We are also implementing an ATOMIC disk server. We are continuing efforts to deliver a significant portion of ATOMIC's 640 Mbps network bandwidth to the user application, subject to host backplane limitations. ATOMIC-ATM Gateway We are currently investigating the use of both the Naval Research Laboratory's PTAI2 ATM interface, and Fore Systems' SBA-200 interface for building Atomic - ATM gateways. We plan to implement IP level gateways using both interface systems (boards and device drivers). We installed Myricom's S-Bus 2.0 host interfaces and Fore SBA-200 ATM cards on a Sun SPARC 20/51, and ran a simple IP gateway test. We found that the performance was dependent on packet size for UDP, but not as much for TCP. TCP performance was around 40 megabits/second, and dropped only slightly for the gateway vs. unicast ATM or ATOMIC traffic. We believe this indicates that host processing is the bottleneck, and we are looking into alternate TCP implementations (TCP Vegas, X-kernel TCP, etc.). Cooper [Page 25] Internet Monthly Report November 1994 UDP performance was limited to near 75 Mbps for ATOMIC, and 100 Mbps for even a 140 Mbps-capable ATM card. We are looking into modifying the host interfaces to transfer packets directly between each other, rather than involving host routing software.

We found that the bandwidth depended on an interaction between packet size and page size for pages over 4K bytes. This was probably due to multi-page packet effects, due possibly to page swapping, TLB effects, or other page boundary effects. The 290 Mbps upper bound is related to the 320 Mbps peak bandwidth of the SPARC SBus, combined with per-burst overhead of bus arbitration. Using DMA for data transfer increased bandwidth remarkably from the programmed I/O case. DMA achieves 290 Mbps as packet size increases, and PIO was limited to 78 Mbps. Because the ATOMIC interface is capable of higher packet bandwidth Cooper [Page 26] Internet Monthly Report November 1994 than ATM, we would expect ATOMIC UDP to be higher bandwidth than ATM, which is not the case.

Integrated services are used to support real-time protocols (e.g., RTP) and QoS reservation mechanisms (e.g., RSVP). We are implementing a subset of the core services proposed in the CSZ model, a service model for Integrated Services Packet Networks proposed by Clark, Shenker, and Zhang. Our aim is to design and implement packet scheduling algorithms on the source-routed cut- through networks (e.g., ATOMIC) to provide seamless integrates services over ATOMIC that are emerging on other LAN technologies. The CSZ model proposes a scheduling architecture to support their service model. Packet network systems that support configurable queuing at intermediate switches can implement this architecture by Cooper [Page 27] Internet Monthly Report November 1994 using multi-level queues. ATOMIC uses source-routed cut-through packet switching, with hard- wired "fair" switching at each stage and hardware backpressure, i.e., no queuing, and no programmable switching algorithm. ATOMIC will have to adjust source routing and the timing of packet emissions to emulate the multilevel queuing mechanism proposed by CSZ. We are currently considering schemes based on an emulation of switch reservation at the centralized arbiter (i.e., the route server), combined with frame-based leaky bucket mechanisms at the hosts (e.g., SNR). Using X-Kernel to support the ATOMIC-ATM gateway We are currently evaluating the x-Kernel (Peterson, Arizona) as a possible vehicle for protocol experiments that bypass the current BSD implementations of TCP/IP. We are seeking ways to provide higher bandwidth to the application, as well as a mechanism to support more efficient gatewaying using multiple host interfaces. We plan to use the x-Kernel to investigate experimental protocol implementations, e.g. TCP Vegas, and direct coupling of the lowest level of the x-Kernel and the drivers for various high-speed networks including ATOMIC and ATM. High performance authentication - Report on MD5 Performance (full text available from ftp://ftp.isi.edu/pub/hpcc- papers/touch/md5.txt) MD5 is an authentication algorithm, and has been proposed as one authentication option in IPv6. When enabled, the MD5 algorithm operates over the entire data packet, including header (with dummy values for volatile fields). We are concerned with how fast MD5 can be implemented in software and hardware, and whether it supports the network bandwidth we're installing here at ISI. RFC 1321 describes the MD5 algorithm and gives a reference implementation [1]. The Internet Draft draft-ietf-sipp-ap-04.txt describes the IPv6 authentication option, and MD5's role in it [2]. We have found that MD5 cannot be implemented in existing technology at rates in excess of 267 Mbps, and cannot be implemented feasibly at rates in excess of 70 Mbps. These rates cannot support ISI's ATOMIC LAN (640 Mbps raw, 36 Mbps TCP, 75 Mbps UDP currently). We believe that if MD5 cannot support existing network bandwidth using existing technology, that situation will not change in the future. Cooper [Page 28] Internet Monthly Report November 1994 We ran a reference implementation of MD5 written in C posted by Jim Ellis at CERT. Here are the data rates we got from the performance test "md5 -t", which tests 1000 1000-byte blocks through the code: 13 Mbps SPARC-2 SunOS 4.1.3 20 Mbps 486/33 NetBSD 23 Mbps HP 9000/720 36 Mbps SPARC-10/51, SPARC-20/50 SunOS 4.1.3 52 Mbps SGI/IP-20 IRIX 5.2 These rates do not keep up with the bandwidth we support for TCP or UDP at ISI. Our analysis indicates that the best software implementation can run in Mbps at 1.6x the MIPS rate of the computer, i.e., a 100 MIPS machine can support a 160 Mbps stream. These bounds are supported by our measurements, above. In hardware, our analysis indicates that the following rates are possible: CMOS 70 Mbps ECL 157 Mbps GaAs 267 Mbps These are also less than required for the ATOMIC LAN at ISI. We propose an alternative to MD5, that is 8- or 16-way block chained, rather than 1-way. We believe that the resulting algorithm achieves the goals of MD5 over MD4, but without the serialization penalty that prohibits high speed implementation. It would require further analysis to ensure that it provides an adequate level of security.

ROUTING ARBITER PROJECT The production CNMS (Centralized Network Management System) is installed in the University of Michigan/Merit NOC, and installation of the centralized Rover code is almost complete. Bill Norton has developed an architecture for distribution of Rover code and updates to the Route Servers. A model for supporting a variety of data collectors on the Route Servers has been created, and the staff has designed a secure method for downloading collected NAP data to the CNMS. Joint tests conducted this month by Merit, IBM, and ISI verified that new Route Server software allows remote backup of the Route Servers, in the absence of dual Route Server connections at some NAPs. RIPE and Merit have completed the migration from the RIPE-81 syntax to the RIPE-181 syntax, and the Routing Arbiter Database (RADB) is up and running. Installation of a second RADB system, for development and hot backup, is also complete. The RADB is expected to replace the Policy Routing Database, used for the NSFNET Cooper [Page 35] Internet Monthly Report November 1994 Backbone Service, by the end of December. The RADB itself forms part of the new Internet Routing Registry, which will incorporate registries maintained by several national and international networking organizations. If you are a NSF sponsored regional network, a North American networking provider, or another provider and you need help in using or registering in the RADB, send a message to db-admin@merit.edu. John Scudder, Laurent Joncherey, and Craig Labovitz have been working to secure the Route Servers, Routing Arbiter Database systems, and Centralized Network Management System. They installed s/key one-time password authentication with local modifications, installed several security audit packages, and improved security on staff machines at Merit. NSFNET BACKBONE SERVICE PROJECT Peering sessions have been established between the ANS/NSFNET backbone and Network Service Providers at two NAPs. At the PacBell NAP, ANS/NSFNET is peering with MCInet; at the Sprint NAP, ANS/NSFNET is peering with SprintLink. Two regionals, MOREnet and THEnet, have completed their transition from the NSFNET backbone service, and are obtaining interregional Internet service from SprintLink. These cutovers did not result in any downsizing of the NSFNET backbone service; all of the ENSS's on the backbone are still in place. Due to numerous dependencies, some technical and some administrative, other regionals that had planned to move their primary Internet connection off the NSFNET backbone by the end of November have delayed their changeover, and now plan to make the transition in December. On behalf of the NSFNET Backbone Service Project, Elise Gerich gave presentations about the NSFNET transition at a MIDnet seminar titled "A Practical Guide to Secure Internet Connections" and at the NorthWestNet Eighth Annual Meeting. The NorthWestNet meeting also included a presentation by Gerich on the Policy Routing Database --> RADB transition. In addition, Jessica Yu attended the CoREN technical meetings this month on behalf of the RA Project. Susan R. Harris (srh@merit.edu) Cooper [Page 36] Internet Monthly Report November 1994 NORTHWESTNET ------------ Eighth Annual Meeting Nov. 8-10 =============================== Has it really been eight years?? Indeed it has. From 15 attendees in San Diego in 1986 to over 280 persons attending this year's NorthWestNet Annual Meeting in Portland, Oregon, the audience, the interest, and the topics (not to mention the Internet) have all grown. Participants took every opportunity to learn, share, debate, and speculate. The major themes addressed by the plenary speakers (see below) included the NSFNET transition; programs/projects that are leveraging the increased commercial presence on the Internet with its introduction to the public sector at large; and several views from different levels of government on how to move the National Information Infrastructure forward. Plenary presentations: --------------------- "Public-Private Partnerships to Build the NII" Laura Breeden, Director TIIAP, Dept. of Commerce "Connecting to the Community through the Internet" Mayor Liz Kniss, City of Palo Alto "Evolution of the Internet" Stephen Wolff Director DNCRI, National Science Foundation "Public Policy and Legislative Conflicts: The Network World" Robert Gillespie Principal, Robert Gillespie Associates "The NSFNET Project: Yesterday, Today, & Tomorrow" Elise Gerich Manager Internet Engineering Group, MERIT "Internet Evolution and NorthWestNet" Eric Hood Executive Director & CEO, NorthWestNet and President, FARNET Concurrent Sessions: ------------------- Over 25 presenters contributed to a series of excellent, concurrent sessions and workshops. A brief selection of the topics included: o commerce on the Internet and models for electronic cash transactions (Clifford Neuman, Scientist/Research Asst. Professor, University of Southern California, Information Sciences Institute). o a current perspective on Internet security (Tom Longstaff, Cooper [Page 37] Internet Monthly Report November 1994 Computer Security Researcher, Computer Emergency Response Team, Carnegie Mellon University); o the future of Gopher (Mark McCahill, Internet Project Gopher leader at the University of Minnesota); o an overview of successful commercial use of the Internet (Russ Jones, Internet Program Manager for Digital Equipment Corporation); o new product development with the Internet in mind (Mitchell London, President of ConnectSoft); o ATM networking and the NERO project (Dave Meyer, Senior Network Engineer at the University of Oregon); o strategies and tactics for getting information out via WWW (Don Retallack, Advanced Computing Technologist at Boeing Computer Services); o K-12 and the Internet (panel moderated by Kristin Boden-MacKay from the Northwest Regional Educational Laboratory); o electronic media's hidden liabilities from a legal viewpoint (Joan Feldman, President of Computer Forensics, Inc); Everyone got a chance to flex their Internet brain cells, when three randomly selected teams of four persons competed in the first annual NorthWestNet Internet Quiz Show. Questions that stumped all three teams were opened to the audience. All team members and audience participants received ample rewards of chocolate. The teams--NetEscapers, IFF, and NetNerds--were all excellent, earnest, and good-natured competitors. The Tuesday night social event offered refuge from the rain and escape from the hotel. The Oregon Historical Society and Cisco Systems Inc. sponsored food and drink in the engaging surroundings of the Oregon History Museum.

ICB Infrastructure, DSI activities, possible use of ATM and the possibility of collaboration udner the European ACTS and Framework IV program in general were discussed. A UDP based secrure login protocol has been developed in line with ALF principles for the HIPPARCH project. This is the third in a line of new cut-through application/protocol systems, following a video decoder and a shared network text editor, to be designed and Cooper [Page 39] Internet Monthly Report November 1994 implem,ented. Lessons from these will be presented at the HIPPARCH workshop at INRIA in December. IP Multicast over ATM is being tested between UCL, Edinburgh and Cambridge with a view to moving the UK mbone over to a colection of routers with point-multipoint PVCs between them to get higher bandwidth and more efficient transmssion capacity utilisation at the same time. Early testing is promising, but fraight with configuration complexity! There are high hopes to extends this testbed on into Europe in January.

The file is called izs96-cfp.txt. Cooper [Page 50] Presently we were in a very dark road, and at a point where it dropped suddenly between steep sides we halted in black shadow. A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù ENTER NUMBET 0016l5n31.net.cn
