eek Captain Spinney received word that the 
^vernment had shipped a fine surf boat about

Naval Architects’ Meeting. 
The annual meeting of the Naval Architects 
hd Marine Engineers was held in the building 
f the Engineering Society, No. 29 West 39th 
treet, on Nov. 19 and 20. Admiral Bowles, 
resident of the Fore River Shipbuilding Com- 
any, acted as chairman. After the two days’ 
iscussion of various topics, the members dined 
^gether at Delmonico’s. Many interesting 
apers were read, the substance of which was 
s follows: 
The War Eagle—1904. By Charles H. Cramp, 
r ice-President. This paper gave particulars of 
n oyster boat, the War Eagle, built on the 
,nes of a “pungy,” a type of boat made famous 
a Baltimore in the early fifties, and which 
.roved the fastest in both the Delaware and 
Ihesapeake Bays, as stipulated in the contract. 
The Oldest Iron Ship in the World. By 
Henry Penton. This is the old U. S. warship 
Volverine (ex-Michigan), which composes the 
vhole U. S. Navy on the Great Lakes. She 
vas built by Stackhouse & Tomlinson, of Pitts- 
>urg, sixty-six years ago, and the material for 
ler construction was dragged across the moun- 
ains from Pittsburg to Lake Erie. 
Practical Methods of Conducting Trials of 
/essels. By Col. E. A. Stevens, Vice-President. 
This paper referred to the loose methods, under 
vhich speed trials are often carried out in this 
:ountry, outside the navy. The author has de- 
ised an apparatus for recording simultaneously 
ime on the course and revolutions which he de¬ 
scribed at length. 
The Influence of Midship-Section Shape upon 
lie Resistance of Ships. By D. W. Taylor, 
STaval Constructor, U. S. N., Vice-President. 
This subject, upon which naval architects differ 
so much, was investigated at the. U. S. Model 
Basin. Forty models were tried in all and the 
results obtained are outlined in this paper. 
Further Experiments Upon Longitudinal Dis- 
ribution of Displacement and Its Effect Upon 
Resistance. By Prof. Herbert C. Sadler. In 
i previous paper last year the author gave the 
■esults of some experiments upon resistance as 
effected by distribution of displacement. The 
present paper gave data on similar experiments 
for finer and fuller forms. 
Further Propeller Analysis. By Clinton H. 
Crane. In this paper a new horsepower formula 
was presented by the author. 
Deviation of the Compass Aboard Steel Ships 
—Its Avoidance and Correction. By Lieut. 
Com. L. H. Chandler, U. S. N. . This highly 
important subject was discussed in this paper 
in the light of the general mathematical prin¬ 
ciples involved from the results obtained aboard 
the vessels of our battleship fleet. It called the 
attention of shipbuilders to the question of the 
magnetic effect of the structure of a steel ship 
upon the compass with a view to relieving the 
burden of navigators as a little lack of under¬ 
standing or care in regard to this point on the 
part of the designer and builder often places the 
navigator from the start under a severe and un¬ 
necessary handicap. 
The Influence of Free Water Ballast Upon 
Ships and Floating Docks. By Naval Con¬ 
structor T. G. Roberts, U. S. N. This paper 
reviewed the theories governing the various 
considerations of stability of a floating dock 
throughout its various operations. 
Some Recent Inventions as Applied to 
Modern Steamships. By W. Carlile Wallace. 
The author reviewed the innovations introduced 
in the building of the new Cunarders as regards 
bulkheads, ash ejection through ship’s bottom 
by compressed air as adopted in these vessels 
and in the latest British and American war¬ 
ships: the cooling of staterooms in the tropics 
and the maintaining of a uniform temperature 
in electrically heated staterooms. The latter 
method, however, is costly. To maintain a

temperature of 70 degrees F. in an ordinary 
outside stateroom of an Atlantic liner during 
the coldest weather encountered on the north¬ 
ern track, it is necessary to supply a 1,200-watt 
heater, which heater is much too large during 
nine-tenths of the time during which artificial 
heat is desirable. 
Service Test of the Steamship Harvard. By 
Prof. C. TT. Peabody, W. S. Leland and H. A. 
Everett. This steamer, which is propelled by 
Parsons’ turbines, is 386 feet 6 inches long by 50 
feet 6 inches moulded and 63 feet extreme 
beam, by 22 feet depth. The normal draft is 16 
feet. The engine test gave the following re¬ 
sults: Average revolutions (6 hours), 455; aver¬ 
age shaft horsepower, 10,405; coal per shaft 
horsepower (average of 6 hours), 1.5 pounds. 
Trials of the U. S. Scout Cruiser Chester. By 
Charles P. Wetherbee. This cruiser, built by 
the Bath Iron Works, Ltd., Bath, Me., is fitted 
with Parsons’ turbines. The final four-hour 
trial run on Oct. 21, 1908, on a displacement of 
3,630 tons, gave the following results: Mean 
revolutions per minute, 590.1; speed per hour, 
26.1 knots; miles per ton of coal, 1.5; coal per 
indicated horsepower per hour on basis of 0.55 
propulsive coefficient, 1.78. 
Some Remarks on the Steam Turbine. By J. 
W. Powell. This paper reviewed the history of 
steam turbine and paid particular attention to 
the developments of the Zoelly turbine, which 
the author terms the best example of the pure 
action turbine with multiples stages. 
Shipbuilding on the Great Lakes. By Robt. 
Cuar. This paper described at length the 
methods of construction and fitting in vogue at 
Great Lakes shipyards. 
The steamer Commonwealth. By Warren T. 
Berry and J. Howland Gardner. This paper 
contained an elaborate description of the well- 
known Fall River Line passenger steamer 
Commonwealth, built for the night service be¬ 
tween New York and Fall River, a run of 180 
statute miles, including a one-half hour stop. 
The contract builders were the Quintard Iron 
Works Co. The hull was built by Wm. Cramp 
& Sons Co. and the steamer was finally de¬ 
livered on Tune 23, 1908. The maximum speed 
is 22 statute miles per hour, although 18 miles 
is all that is required in actual service. 
Centrifugal Pump Fire-Boats. By Charles C. 
West. In this paper a description was given of 
the first centrifugal pump boats to be used on 
the Great Lakes, the Joseph Medill and Graeme 
Stewart, designed by Mr. W. I. Babcock for the 
city of Chicago. The dimensions are 120 feet 
by 28 feet by 15 feet, with 500 tons displace¬ 
ment and a draft of 9 feet 6 inches. The main 
pumping and power machinery consists of two 
660 horsepower Curtis turbines direct connected 
to 200 k.w. direct-current generators and two 
stage centrifugal pumps. The generators serve 
to provide current for the propelling motors 
which are of the variable speed reversing type. 
The capacity is 9,000 gallons per minute, which 
could be raised to 10,000 gallons at 150 pounds 
pressure. 
Sea-Going Suction Dredges. By Thomas M. 
Cornbrooks. This paper described the dredge 
Galveston, just completed by the Maryland Steel 
Co., and also gave the curves of bending 
moments and equivalent girder for the latest 
New York harbor dredges Raritan and Nave- 
sink. 
The British International Trophy Race of 
1908. By W. P. Stephens. In this paper inter¬ 
esting details were given of the particulars of 
the motor boats engaged in the race of Aug. 3. 
1908, at Huntington Bay, Long Island, and 
which was won by Dixie II., covering the tri¬ 
angular course of ten nautical miles, run three 
times, in ih. 4m. 57s. 
Transportation of Submarines. By Naval 
Constructor W. J. Baxter, U. S. N. This im¬ 
portant nroblem of transportation as solved by 
the officials of the Navy Department, was de¬ 
scribed at length in this paper. Two sub¬ 
marines, 64 feet 9 inches over all, by 11 feet 10 
inches diameter, were sent from the Navy Yard, 
New York, to a distant port on a collier, 322 
feet over all. 43 feet extreme breadth, 23 feet 
inches depth moulded, and launched from
