she has never before particularly distin-
ouished herself as a speodsr, and Mondays
l schievemenE is to be regarded as the con-
ANIMATION of a number of experiments
rbieh the Mcbride brothers have carried
/ on since owning her.
The general appearance OF the Yankee
Doodle is TIA It OF an ordinary steam Launch.
She Is so feet long, 6 feet inches beam and
Quiet draws fifteen inehes of water. She Is
20 ahout four tons q SDlacoment
The interesting point in connection with
the Yankee Doodle's remarkable develop
Tnent of seed Is tne fact that the improve
menrs which she has recently undergone
have had nothing to do with the model of
her hull. In this no changes at ell have
been made. The whole secret Of her great
speed lies in her boiler and screw. Both the
new wheel and the new boiler have been
especially designed for the boat by Mcbride
& Fisher.
The chief Improvement, so far as the
boiler is concerned, consists in the suhstitu-
tion for the old, original locomotive boiler
with pipe firebox furnace of tubular or
pipe boiler, consisting Of 40 1-inch seamless
steel tubes. These tubes contain the water
which is Immediately converted into steam
by the fire from the furnace, to which the
exterior of all the tubes Is freely exposed.
The tubes recently stood the severe test of
1900 pounds hydrcstatic pressure to the
square inch, although the actual pressure to
which they are subjected Is but $50 pounds.
The boiler has $50 feet Of tubular heating
surface. The tubes lie parallel with the
hull. The weight of the boiler itself 10 2, 900
pounds, while the weight Of tue water when
the launch is in running condition is 800
pounds. 1t is claimed that this is one of the
lightest boilers with an equal amount of
heating surface that has ever been made,
and its Importance for yachts and steam
hOo "a 10 oh Hha "a t,rfo Sr,f
furnace Is about 8 feet. The CRATE bars
weigh IS pounds. The length Of the CRATE
bar furnace is feet inches.
The greatest gain of speed, however, is
due TO an entirely new principls of con-
struction in the arrangements Of the steam
dome, which is feet by 2. 1t is in this
respect, that the builders lay greatest
claim to originality. The dome, instead of
being placed parallel with the length, as is
usual, is built crosswise The purpose of
this is to prevent the steam pipe from ship
ping water when the boat rolls. In this
way the water line in the boiler is pre-
served unchanged, and q consequence is
that the boiler manufactures absolutely dry
steam. There is thus, also, no need of any
centrifugal separator, as on most boats TO
separate the water from the steam 10 order
to prevent the boiler from "priming" into
the cylinders under a high velocity OF
steam. II is in this respect that the boiler
Ia essentially different from all other boilers.
The increased speed of the Yankee Doodle
Is also partly due to its newly designed
screw. This Is d 34-inch wheel, with
5-feet 10 inch pitch. II has two blades and
its maximum number Of revolutions is said
TO be $50 per minute. The old wheel OF the
Yankee Doodle was 30-inch, and the supe-
riority Of the new wheel consists, in addi-
ton to its larger size, in the fact that It's
dikes are soped at a much larger angie
&I,o ,r,I L.,
discharge the water more to the right and
left, and less directly TO the rear as did the
old wheel. The advantage of this ar
rangenent has most paIpably revealed itself
In its reducing almost to nothing the here
tofore violent vibration OF the boat while
laboring under the pressure incident to a
high rate of speed. This is shown in the
fact that the original wheel stood only 100
pounds Of steam, while the present wheel
stands $50 POUNDS.
The engine is indicated as 160-horse
power. 1t is run under high pressure, and
has two S~inch by e-inch single cylinders,
cut off at half stroke. The boiler shows
steam in two minutes. while in twelve min
utes ID will show the full head of steam.
Mcbride Bros. have all along felt san
gnine Of the high speedy qualities of the
Yankee Doodle as improved by them, and
the trial run on Monday last confirmed their
highest hopes. The only steam launch
which approaches the speed of the Yankee
Doodle is the Norwood. owned by Norwood
l.. Munro of New York. IL appears that
on June % Mr.. Munro issued challenge
and deposited in the Marine National Bank,
YORK, $4,000 for any steam yacht to beat
his Norwood. Mcbride Bros. on June 25
wrote the following letter to Munro:
DEAR SIR-We notice In New York Sun and
other papers your offer to pay the owner of any
yacht that can beat the Norwood one mile the

that our steam yacht, Yankee Doodle, would oe
good compHttor to the Norwood, and will
therefore, with your consent, accept your offer
the date OF the race to be fixed hereafter, ais
the water in which it will take place, probably
upon the Hudson. some distance to fresh and
smooth water. You know we don't use con
densers and have only high pressure cylinders
our delaware river would be q good, smooth
water 10 run, but suppose you would prefer the

would be pleased to hear from you.
