SIGNS or THE FUTURE.
It Is not alone the fact that she IL
the fastest boat Of her size vet built
which makes the marvellous little craft
worthy Of attention. Vastly more in
teresting is she as evidence that the
time Is not FAR distant when the inter-
nal combustion engine which works by
me explosion Of yapor or gases, will
dispace the steam engine as the chief
instrument Of mans mastery over the
sea, on that subject no man is more
competent to speak with authority than

SO II may be taken that the adoption
Of the internal combustion engine Tor
q vessel OF this size really represents
an additional speed " 10 knots an hour.
The speed Of vessel increases rap
ldly with It's size, For example, i'm
what Is termed a secOnd-class torpedo
boat 60 feet In length, the best speed
we could obtain would be 20 knots but
FOR vessel say 200 feet IN length, with
porpOritnately larger machinery. "A
speed Of 30 knots could be oBtained.
Therefore, the obtaining OF q speed OF
practically .6 knots In a boat only 40
feet In length, points 10 the possibility
In the not far distant future of bro
polling "a vessel OF 22O feet I'm length
such as the destroyers we built for the
