Society of Naval Architects and 
Marine Engineers. 
The tenth annual meeting of the Society of Naval Ar- 
chitects and Marine Engineers was held in the auditorium 
of the American Society of Mechanical Engineers at 12 
West Thirty-first street, on Thursday, Nov. 20. The an- 
nual election resulted in the re-election of Mr. Clement 
A. ^Griscom, who has now held the office of president for 
ten- years. The following papers were read during the 
da^r's session; 
"Technical Training for Shipbuilders," by Henry S. 
Pritchett, LL. D. ; "Progressive Trials of the Screw 
Ferryboat Edgewater," by Edwin A. Stevens, vice-presi- 
dent, and Charles P. Paulding, Jr.; "The Possible and 
Probable Developments in the Use of Electricity on Board 
Ships," by F. O. Blackwell ; "The Preliminary Official 
Trial of the U. S. Battleship Maine," by Assistant Naval 
Constructor J. W. Powell, U. S. N., associate; "The Wa- 
ter Tube Boiler in the American Mercantile Marine," by 
William A. Fairburn; "Longitudinal Bending Stress on 
Damaged Ships," by George C. Cook; "Some Problems 
on the Surfaces of Buoyancy and of Water Lines," by 
Prof. Cecil H. Peabody. 
The paper on water tube boilers by Mr. William A. 
Fairburn contained interesting references to the use of 
oil as fuel in steamships. The paper says : "At the pres- 
ent time liquid h\cl is being used on several ocean going 
merchant vessels, and the leading navies of the world are 
diligently experimenting with it." 
Mr. Fairburn enumerates among the advantages of oil 
fuel : 
Saving in weight of fuel and also in bunker space. 
Two tons of oil have an evaporative efficiency equivalent 
to three tons of coal. 
Saving in labor — ^the number of men required being 
only about one-fourth of the number required with coal 
fuel. 
Ease in taking fuel on board. 
No lost space in storage. 
Cleanliness. • 5 
Speed in filling tanks with fttel. Saving of detention 
at calling ports. 
Fires do not require cleaning. 
No ashes to handle. - 
Reduced temperature of firerooms. 
Increased life of boilers, due to constant temperature. 
Improved engine performance, owing to constant steam 
pressure. 
Fires always clean a'iid in good condition, which ma- 
teHally increases the average working power of the boiler. 
With coal fires the power drops as the fire gets dirty, and 
it drops still more when the fires are being cleaned. 
When atomizers are properly regulated the combustion 
can be made complete and there is no smoke. 
In conclusion, Mr. Fairburn ?ays that oil is destined to 
supplant coal as steam making fuel on the seas. 
One of the most interesting papers was that of Naval 
Constructor Powell on The Preliminary Official Trial of 
the U. S. Battleship Maine. 
Constructor Powell described the trip and said : 
"In the fore and main, both lower and. upper, tops only 
a very moderate amount of practically constant vertical 
Adbration was noted, and the same was true of both the 
forward and after bridges. Throughout the waist of the 
ship the vibration was hardly noticeable. The vibration 
at seventeen knots was slightly more marked than that 
at eighteen knots." 
Of the reversing test of the engines he said : 
"This consisted of stopping aiid reversing the engines 
as quickly as possible, starting with engines going ahead 
at full speed and noting the time until each stopped, until 
each started astern and until each was making full speed 
astern. The time required to pass from full speed astern 
to full speed ahead was then noted. 
From full speed to stop took gs. with both port and 
starboard engines ; from stop to astern, 5s. with star- 
board engine, 6 with port ; from stop to full speed astern, 
60s. with starboard engine, 55 with port; from full speed 
astern to ahead, 5s. with both engines. 
The meeting was continued on Friday, Nov. 21, and 
papers were read on the following subjects: "The Tactics 
of the Gun," by Lieut.-Commander A. P. Niblack; "Sub- 
^ marine Torpedo Boats ; Past, Present and Future," a 
i paper by Lawrence Y. Spear ; "Vibration of Steamships ; 
\With Special References to Those of the Second and 
'Higher Periods," by Rear Admiral George W. Melville; 
"The Development of Modern Ordnance and Armor in the 
United" States." by Rear Admiral Charles O'Neill ; "Re- 
marks on the New Designs for Naval Vessels," by Rear 
Admiral Francis T. Bowles; "The Possible and Probable 
Future Developments in the Use of Electricity on Board 
Ships," by F. O. Blackwell; "Measurement Rules for 
Yachts, with Special Reference to Racing Conditions," by 
F. W. Belknap. 
Alter the reading of these papers had been finished the 
meeting of the Society was adjourned, and in the evening 
the tenth annual banquet was held at Delmonico's. 
Those at the large circular guest table included Messrs. 
A. K. McClure. P. A. B. Widener, J. J. Hill, Myron T. 
Hcrrick, A. A. Raven, S. A. Huhn, C. H. Haswell, Fred- 
erick M. Storm, C. M. Goldfogle. Edwin Cramp, J. F. 
Hanscom and Rear Admirals P. C. Asserson, A. C. En- 
gard arid Francis T. Bowles, Captain J. A, B, Smith, 
Clement A. Griscom, Frank L. Fernald, Charles Loring, 
Lewis Nixon. John C. Kafer, Edwin A. Stevens, W. 
Wing Babcock, Washington L. Capps, Wm. H. Jacques, 
Frank B. Ring, Henry G. Morse, Horace See, George E. 
Weed and others. 
One hundred and sixty persons were present, and Mr. 
Griscom acted as toastmaster. The speeches were jn- 
■ formal.

Dofwina and Effort* 
Throughout the past season on the Sound, Dorwina 
and Effort, of the 4.'3ft. class, were raced very persistently, 
and their performance was followed with considerable in- 
terest. 
Dorwina is a Gardner boat built by Wood at City 
Island, in 1901. She is now owned by Mr. Clifford V. 
Brokaw, N. Y, Y. C. Her dimensions are 60ft. lin. over 
all, 35ft. waterline, 12ft. extreme beam, 9ft. draft. 
Effort was designed and built by the Herreshoff Mfg. 
Co., and is owned by Mr. F. M. Smith. She is s8ft. over 
all, 36ft. 6in. waterline, lift. ain. beam, and 8ft. loin. 
draft. In our illustration the boat on the right, L 3, is 
Dorwina, with Eft'ort, L 10, out to weather. 
YACHTING NEWS NOTES. 
It is reported that the actual work on the new cup 
defender will commence very soon at the Herreshoff 
works, as the mould for the keel is ready and the lead 
will be run in a few days. It is hoped to have the boat 
ready for launching by the first week of April, which will 
give over three months for tuning up trials.

From across the water comes the report that Sham- 
rock III. has begun to take form in the Dumbarton yards 
of Messrs, Denney & Co., and that a few persons have 
been privileged to see her. It is said that Fife has gone 
in for an easier form and a smaller wetted surface than 
in the first Shamrock, and that the draft has been carried 
to the extreme of 26ft. bin. 
Next season the yachtsmen of Milwaukee will make 
an attempt to capture the Lipton Cup, which is now in 
the possession of the Columbia Y. C. of Chicago. One 
of the boats which will compete is the Massachusetts 
2i-footer Pilot, which has been recently sold by Mr. 
Reginald Bordman, of Boston, to Mr. R. B. Brown, of 
Milwaukee, through the agency of HoIHs Burgess.

The schooner of 90 tons, built last year by the Hanley 
Construction Company, at Quincy, Mass., and never put 
in commission, has been purchased by Boston parties, 
and will be converted into a fisherman. She will be in 
charge of Capt. Doughty,

Capt. Christopher S. Crosby, one of the best-known 
yacht commanders in this country, died recently at his 
home in Philadelphia, aged sixty-eight years. "He was 
born in Eastport, Me,, and went to sea when young, 
but abandoned deep sea sailing for yachting some years 
ago. His best-known achievement was in command of 
the Coronet in his famous ocean race from New York 
to Queenstown in 1887 against the Dauntless. Capt. 
Crosby was a prominent member of the Masonic Order.
