"The journal of the Franklin Institute, for June, contains quotations from the Nautical Magazine, furnishing data respecting the Lake Propellers, International, Buffalo, and Oriental, with remarks from the pen of a valued friend and correspondent. ;'
The journal referred to, although occupying a place on our exchange list, did not come to hand until our pages were full ;
as a consequence, we have no space for enlargement, and can only refer to the subject in such manner as to elicit attention. With regard to screw propulsion on the lakes, however desirable [p. 336] fuller accounts may be in the consumption of fuel, &c., we
have enough to establish the fact, that the screw, as there
applied, with the axis above water, and with an equal amount of
power, is superior to the submerged screw or the paddle-wheel
for speed. As to Captain Whittaker's application, it does not
wholly consist in the emerged screw, but also in direct action
high-pressure engines, placed upon the gunwale of the vessel,
and, we may observe here, that this principle is attracting attention in England. With regard to the wheel of the Iron
Witch, designed by Captain Ericsson, it bore no just analogy
to that used on the Baltic by Captain Whittaker.
