These two points were of the very essence of sailing tactics, and these two points have been eliminated from the modern tactical problem by the changes ofpropulsion and armament.

The human is rarely born these days, who, without long training in the social associations of drinking, feels the irresistible chemicalpropulsion of his system toward alcohol.

So there will be no loss whatever of gas, and all the expansive force of the powder will be employed in thepropulsion."

To the whale, his tail is the sole means ofpropulsion. Scroll-wise coiled forwards beneath the body, and then rapidly sprung backwards, it is this which gives that singular darting, leaping motion to the monster when furiously swimming.

There was one thwart set as low as possible, a kind of stretcher in the bows, and a double paddle forpropulsion.

The medium of buoyancy is contained within the thin metal walls of the body and consists of the eighth Barsoomian ray, or ray ofpropulsion, as it may be termed in view of its properties.

There was another little idiosyncrasy of design that escaped us both until she was about ready to launch--there was no method ofpropulsion.

Its capital defect is that it requires personal attendance at the point ofpropulsion.

Excellent (and picturesque) Arab owner, about whom one needed not to trouble one's head, a most excellent Scottish ship--for she was that from the keep up--excellent sea-boat, easy to keep clean, most handy in every way, and if it had not been for her internalpropulsion, worthy of any man's love, I cherish to this day a profound respect for her memory.
