"J. W. L.," says: " In cutting grass with a lawn mower on a slope of considerable inclination, the method customarily followed, at least by the gardeners for the railroad companies, is, to attach a rope to the user of the machine, said rope to be held by an assistant standing on the top of the bank. A second rope is also frequently attached to the machine itself, and is held by a second assistant. The work is certainly onerous for the man working the machine, yet in watching the floundering of one so occupied at one of Germantown's West-side railway stations, it occurred to me that the operator might have saved a good deal of strength and perspiration, have cut a less ludicrous figure, and have performed the work more expertly and satisfactorily, had he been provided with a pair of shoes having deeply corrugated soles, such as are used by lawn tennis players. I so advised him. Is there any worth in the suggestion, and does the Editor know whether shoes of the kind referred to are used as indicated? "

[The suggestion is a valuable one. It is, however, a matter wholly for experiment. So far as we know, it has never been tried in that way. - Ed. G. M].
