partial balance of the lower foreside gradually reduces the strains,
the rudder head may be made of very great service. As a matter of
fact, this rudder is 230 ft. in area, and is probably the largest
rudder fitted to a warship. The efficiency of it was shown in the
turning trials, by its being able to bring the vessel round, when
going at about nineteen knots, in half a circle in one minute
twenty-three seconds, and a complete circle in two minutes fifty-eight
seconds, the diameter of the circle being 350 yards. This result, we
believe, is unrivaled, and makes this vessel equal in turning
capabilities to many recent warships not much more than half her
length.

FILM NEGATIVES.[1]

Society.]


Having had a certain measure of success with Eastman stripping films,
I have been requested by your council to give a paper this evening

which my experience has found most successful. In according to their
request, I feel I have imposed upon myself a somewhat difficult task.

There is, undoubtedly, a strong prejudice in the minds of most
