United States paddle wheel steamers Wnooski and Al
gonquin have the honor submit the following prelim
nary report OF the result Of tho trial Long Island
Sound for maximum power Of machinery and speed Of
vessel and for economy Of fuel under these conditions
1t will be followed by full report embracing the re-
suits OF all tho trials at the wharf well Of that on
Long Island Sound together with conclusions from
tho same. and all the data IN ertenso.
rHx OBSTACLES TO rHE FULL PERFORMANCE or rHS RACE
The trial on Long Island Sound intended TO
brace eight consecutive double runs, between Execution
Rock Lighthouse and Faulkners Island Lighthouse pass,
ing around both. Each double measured ON tho
vessels' track was, according to the coast sur
yey chart ll3 geographical miles; but violent
storm, accompanied by weather 80 thick as to pre-
vent the lights being beyond q mile or two, and
the refusal Of the pilots 10 run In IT, terminated the trial.
after the Winoosk had performed three double runs
800 geographical miles, and the Algonquin two double
runs 2?6 geographical miles Our data and results arc
accordingly for these distances respectively Both yes
sells portion OF the distance the next but
that portion omitted because the exact position Of the
vessels could not be determined whom they decided 20

THE CONDITION OF vxssns
Neither vessel seered WELL but they about equal
in this particular which, OF course still further essened
their speed The machinery OF both vessels was in
celent order. That of the Algonquin, after the come
ton Of the wharf trials, had been for two and half
months the hands Of the contractor for repairs during
which time he had renewed all the vertical tubes Of the
boilers, substituting new circulating pump, &C. &c.

main engine was inoperatve ten and half hours, dur.
ing which time the boilers were supplied by tho auxiliary
steam pump; as, however, this pump draws the feed
