The binnacle is aluminum, as is also nearly all of the metal work on 

 the boat in connection with the plumbing and closets. 



It will thus be seen that the main object which the designers wished 

 to accomplish was to get a boat which was not only as light, as possible, 

 but which would have Its center of gravity as low as was practicable, 

 yet, at the same time, to have no aluminum on the outside below the 

 waterline, owing to the fact that aluminum fouls whet) exposed to salt 

 water and collects the barnacles very nearly as rapidly as iron and 

 steel. The above object the designers accomplished with great suc- 

 cess, as was proven by the superb way in which Defender acquitted 

 herself in the races against Valkyrie III. 



Each and every plate used in the construction of the hull was tested, 

 and it can safely be said that, considering the ductility shown, these 

 are the highest tensile tests that have ever been made in any of the 

 alloys of aluminum; especially when it is considered that these tests 

 were made from actual sections, which were quite thick, and eat from 

 the finished plates, two edges of which were left as they came from 



Some adverse criticism was made by several naval constructors to 

 statements in the paper concerning the attitude of the Government in 

 the matter of using aluminum in the new naval vessels. 



The paper on "Rudder Experiments on the U. 8. S. Monterey," by 

 Elliott Snow, Assistant Naval Constructor, TJ. S. N., was read by 

 Sec'y Capps in the absence of the author. The discussion brought 

 out a general appreciation of the importance of the tests described. 

 Naval Constructor D. W. Taylor, IT. S. N,, read a very thorough and 

 comprehensive paper on "Methods and Forms for Certain Ship Calcu- 

 lations," followed by a paper by Prof. W. F. Durand, Cornell Univer- 

 sity, on "The Number of Longitudinal Intervals in Ship Computation, 

 as Affecting the Accuracy of Integration for Displacement," with a 

 note on the subject (reated by him last year, "The Relation Between 

 Reduced and True Netted Surface." 



On Friday the following: papers were read: "Recent Designs of Ves- 

 sels for the U. S, Navy," by Philip Hichborn, Chief Constructor, U. S. 

 Navy; "Tactical Considerations Involved in War Ship Design," by

the rolls, and the other two edges were planed parallel, as it will be 

 seen that the sections tested were about lj^in. wide and of the thickness 

 of the plate from which the specimen was taken. 



The heaviest plate in Defender weighs about 2001bs., is 38J/gin. wide, 

 6 ]() of an inch thick, and 13ft. lOin. long, which is the largest plate of 

 aluminum that has ever been rolled, so far as the author knows. 



This plate gave an ultimate tensile strength of 40,7801bs. per square 

 inch, an elongation of 10 per cent, in 2in., and the reduction of area at 

 the point of fracture was 14.75 per cent. * * * 



The possibilities of aluminum in ship construction, in the mind of 

 the author, are very great, in two classes of boats especially— that is, 

 the first and second-class torpedo-boats. 



There is no reason why, in the second-class torpedo-boats, which 

 are a very short time in the water, they could not be constructed 

 wholly of aluminum. 



This would be advantageous not only from a point of reduction in

^Lieut.Niblack'spape 1 - was particularly rich in suggestioDs.and evinced 

 a careful study of a very important subject. Prof. Aldrich's paper was 

 both timely and to the point, advocating the immediate establishment 

 of State or national institutions for investigation and research in mat- 

 ters of naval architecture and marine engineering. Prof. Denton's 

 paper described some interesting tests of the new steamer City of 

 Lowell, de-igned by Mr. A. Gary Smith, with remarkable results.

Kew Half-Raters. 



Roslyn, L. I. — Editor Forest and Stream: I have just completed for 

 a New York gentleman a one-rater of 16£t. waterline length, 7ft. beam, 

 9in draft. She is of the Bouncer type, with angle bilge; sloop rig, and 

 is fitted with a removable cabin house. We have also now in frame 

 a half-rater 23ft, over all, for a Southern owner. This boat is for racing, 

 and is of the Bouncer tvpe with round bilges. All her frames are iden- 

 tical in shape, so that but one mould is used for getting out all her ribs. 

 Her timbers are spaced 8in. aoart, each being worked from a hack- 

 matack knee, and her entire frame weighs less than SOlbs. The plank- 

 ing and deck will be ot cedar ' la ia, thick, fastened with brass screws. 



I have also orders for two ottier half-raters, to bs commenced before 

 January 1, and have several gentlemen talking about building for this 

 class. I should think that half raters are likely to be as numerous as 

 summer gulls on the Sound next season. Thomas Claphans.

draft, and additional speed, rigidity also following, but also from the 

 fact that, being several tons lighter than any other possible construc- 

 tion, they could be with greater rapidity and facility put over- 

 board incase of emergency, or removed from the water when 

 necssary. 



In the first-class torpedo-boats, where the boats will be overboard 

 for some length of time, and where also a boat of great speed and as 

 light as possible is desired, the construction which has been used in 

 Defender will be hard to improve upon. 



That is. build a boat which, from the waterline down, should be 

 constructed of aluminum bronze, or some other of the bronzes, the 

 aluminum bronze being suggested because lighter sections could be 

 used, and for a given section it is the strongest known metal; the hull 

 could not be built to greater advantage than by building it out of this 

 metal. All the plating above the waterline, and the deck beams, bed 

 plates for machinery, and all her frames could be constructed of alu- 

 minum. 



Great care should be observed, in both kinds of construction above 

 referred to, to use rivets of the same material as the sections which 

 are to be riveted. Care should be taken either to keep the alu- 

 minum painted or keep it clean, if it is desired that it shall have good 

 endurance. 



There are also many places in our large ships where aluminum 

 could be used advantageously, but to go into the individual parts and 

 a discussion on this subject would occupy more time and space than 

 is hers permissible, and there is such a vast amount to be done and 

 considered in constructing the smaller boats of aluminum before we 

 get to the larger ones, that the author does not consider it advisable 

 to enter upon this question at the present time. 



struction of the Nicaragua Canal. The committee of five reported in 

 favor of such a memorial, with one dissenting member; but after a 

 thorough diccussion the report of the committee was not accepted, 

 the opinion of the membars being by a large majority against any 

 action by the Society in a matter which was outside of its avowed 

 object, the encouragement of t&9 art of shipbuilding. 



Ia the evening the annual banquet of the Society took place at the 

 Hotel Brunswick, a large number being present. Among the princi- 

 pal speakers were Congressman Amos J. Cummin gs, of New York, 

 and admiral Meade. 



Corinthian Y. C. of Philadelphia. 



Though but four years old, the Corinthian Y. C. of Philadelphia is a 

 flourishing club, with a large membership and a fleet of 75 yachts, and 

 a very fine station and club house at E?sington, on the Delaware River, 

 at the head of the club course. The officers of the club are: Com., 

 Edgar F. Scott, steam yacht Sagamore; Vice-Cr>m., Russell E. Tucker, 

 cutter Mermaid: Rear-Com., Edwin P. Baugh, Jr . schooner Mon Rex; 

 Sec , Addison F. Bancroft; Treas.. Robert K Neff; Meas., G Herbert 

 MiUett; Fleet Captain, W. Barklie Henry; Fleet Surgeon, A. G Thomp- 

 son, M.D. The hall and "tap room" of the club house are shown in 

 the accompanying cuts. Mr. Robert Baine, to whom we are indebted 

 for the cuts, informs us that the house, which has recently been re 

 modeled without destroying any of its architectural features, is an old 

 Colonial mansion, built on Tinieum Island on the site and partly of the 

 materials of the house of Col Printz, Governor of the Swedish Colony. 

 The antecedents of the place are very appropriate, tha harbor being 

 formed by Little Tinicum Island, which, as old records show, was 

 given to the "keeper of the Governor's yacht." 



Look in the Attic. 



Milwaukee, Wis., Oct. 28.— Editor Forest and Stream: For some 

 time past the Mahn-a-Wauk C. C. men have suffered through numerous 

 thefts committed at our boat house the loss of many articles, such as 

 clothes, tools, etc., besides the damages the intruders had done to the 

 building and our lockers. Nearly every member who had anything in 

 his locker had sustained some lots. How to stop these depredations 

 was a problem that had been considered many time9. and it finally 

 devolved on the genius of the club to carry 'out a good scheme. The 

 last place that an entrance has been effected was through the door 

 leading from our locker room to the veranda over the lake. This door 

 had been broken in several times before, the first being by Mr. A. W. 

 Friese himself some time ago, he having come down there one day 

 without his keys. He promised to have it fixed at once, but neglected 

 to, and the same scheme was worked by others who had no business 

 there, as we soon found out. Finally some other members took it 

 upon themselves to fix this door. One day last month on visiting the 

 place we discovered that this door had been broken in again, and this 

 is where our genius got in his work. A trap was set for the next vis- 

 itor coming that way, consisting of a shelf just over the door loaded 

 with pans, bottles, broken glass, etc. This shelf was so adjusted that 

 when the door opened wide enough to admit a person this whole mess 

 would fall on the intruder's head, and in addirion would release a beer 

 keg loaded with shot and weights Irom its suspended position, strik- 

 ing him just below the belt^-surely an awful thing to run up against. 

 If this did not cripple the victim or knock him over the veranda rail- 

 ing into the lake, a second keg was so adjusted at the head of the 

 stairs leading down to the boat room, lhat itwtuld bestt a-rolling, 

 bumping down the stairway, dragging its line of bottles and cans, 

 making a terrible noise. 



This mechanism was rigged up and tested several times and worked 

 to perfection. The trap was set and left to do its horrible work. For 

 three weeks we watched and waited, expecting any time to hear that 

 the coroner had been sud ienly called to attend a case at the lake 

 front. We were disappointed in not securing our game, but also 

 found part of our trap had been sprung a cumber of times from with- 

 in. This was quite evident that one of our own members was doing 

 this as a joke on the ones who had rigged up the trap. So a consulta- 

 tion was held by these few, and in checking up those who had know- 

 ledge of the scheme and who would be likely to spring the trap in this 

 manner, the conclusion was quickly and unanimously reached that 



was that person. How to retaliate in a fitting manner was the 



next problem. Again our genius came to the front. was known 



to be going out of town for the next few days, so it was decided that 

 one of his canoes would have to disappear The plan was to store it 

 away in the attic. Doors Were taken off hinges, windows removed 

 from their frames, hanging lamps taken down and everything made 

 ready for an easy and quick transfer from the boat room to a cozy 

 little berth under the rafters, where it was covered up with such 

 things as cots, fish nets and other stuff accumulated there, completely 

 concealing its identity. Everything else was replaced in its position, 

 and we waited impatiently, for we knew we were sure of some fun 

 this time. In due time Willie returned from his bicycle trip and 

 immediately went to the boat house. Of course he missed his fine 

 new paddler the first thine, and I will give up any attempt at describ- 

 ing his troubles and perplexities. He interviewed all the people in the 

 neighborhood and looked up everybody around town connected with 

 the club, trying to get some information. Finally he invoked the aid 

 of detectives and the police force. If he will only offer a reward the 

 joke will have gone far enough, but aB yet he is still looking for his 

 canoe. A Mahn-a-Wauk. 



American Canoe Association. 



The annual meeting of the executive commit tee of the American 

 Canoe Association was held on Nov. 11 at Stanwix Hall, Rome, N. Y., 

 with Com. W. R. Huntington presiding. The financial reports showed 

 a most successful year, a cash balance of over $530 being turned over 

 by ex-Sec'y-Treas. Cragge after all expenses of the meet were paid. 

 It was decided without discussion to hold the meet of 1896 on the old 

 camp ground at Grindstone Island in the St. Lawrence River. After 

 considerable discussion, the date was fixed for Aug. 14-28 inclusive. 

 No changes of racing rules could be made, but a numuer were favor- 

 ably passed upon by the committee, to be voted on by mail. The 

 principal ones, proposed by Mr. Butler, were the limiting of sail in all 

 races to 130iq. ft., and the removal of the limit to drop of center- 

 board. After the meeting the visitors were entertained by the Deo- 

 wainsta Canoe Club with an elegantly served dinner at the hotel.
