parent in contrast to the other lack of noise and vibration 
in the boat. 
Mr. Curtis's turbine, so far as the inventor is \yilling 
to take the public into his confidence, is a combination of 
jet and direct flow, by which the inventor has been able 
to very materially reduce the speed of revolutions, and, 
therefore, the difficulty of designing suitable propellers. 
These turbines develop 1,250 horse-power each, with 
a speed of revolutions of only 650. Parson's best result 
on the same basis is in the neighborhood of 2,000. Al- 
though 650 is a high speed of revolution, it is not beyond 
practical limits. 
One great additional advantage of Mr. Curtis's ma- 
chine is that by an arrangement of additional buckets and 
jets he is able to reverse his main turbine at three-quar- 
ters of full power. 
The Revolution can be stopped and started more quick- 
ly than in the case of any such engine the writer, has ever 
seen. 
To run this plant at 2,500 horse-power, two engineers 
only are needed, as against four to six on ordinary triple 
engines of the same power. 
The engine room is free from oil and water, and in this 
respect is a marked improvement to ordinary high speed 
boats. 
So far as steam economy is concerned, it has been 
very thoroughly tested by Professor Denton, of Stevens 
Institute, the result of which test will shortly be made 
public. 
The writer knows that the speed result obtained could 
not be bettered with triple expansion eilgines, using the 
same boiler and auxiliaries. 
Manhasset Bay Challenge Cup 
Conditions. 
Below we give the conditions to govern the races 
for the Manhasset Bay Challenge Cup, for 30ft. sloops, 
to be sailed under the auspices of the Manhasset Bay 
Y. C, of Port Washington, Long Island, next season. 
While a matter of arrangement between the Man- 
hasset Bay and the first club challenging for the cup, 
it is probable that these races will be sailed on the 
Wednesday, Thursday and Friday preceding Fourth 
of July, by which arrangement the various boats in this 
class, which promises to be the most active on the 
Sound, will be enabled to take in not only the cup 
races, but also Larchmont race week, which next sum- 
mer will commence with Fourth of July. 
The conditions have been very carefully drawn up, 
and it is believed cover all possible points on which 
the successful racing for the cup depends. 
The Manhassgt Race Committee for 1903 has just 
been appointed and consists, as last year, of E. M. 
Maclellan, Chairman; Charles D. Mower and Robert 
Jacob.

Matches for the cup shall be limited to yachts propelled by sails 
only, whose racing measurement shall qualify them to enter in the

Long Island Sound, as such classification exists on the date of 
this instrument, or such equivalent classification as said Associa- 
tion may in future adopt. The construction of said yachts shall 
be in accordance with the Definition and Table of Scantlings, and 
any other requirements of the Yacht Racing Association of Long 
Island Sound for such class as in force on the date of this instru- 
ment, or such definition and table of scantlings and other re- 
quirements as said Association may in future adopt, provided, 
however, that any yacht in existence Dec. 1, 1898, that is of sub-

and accepted in the first challenge received; but no other chal- 
lenge shall be accepted, if received later than May 15. 
ARTICLE YII. 
Number of Races, Courses, Starts, Winner of Match, Naming 
Representative, Measuring, Hauling Otit, Protests. 
A match shall be constituted of not less than three or more than 
five races. 
(a) Courses shall not be less than 15 nautical miles in length, 
nor mere than 22 nautical miles, and shall be laid as nearly as 
possible as follows: The first race shall be to windward or lee- 
ward and return. The second race shall be over a triangle, one 
side of which shall be to windward. Subsequent races shall alter= 
nate as above until the series shall have been finished. A change 
of wind, occurring after the start has been made, shall not in- 
validate a race. 
(b) All courses shall be laid in waters of suitable depth for the 
competing yachts, and of sufficient expanse to permit of each leg 
of each course being not less than three miles in length. 
(c) The start shall be a one-gun flying start, with a preparatory
