Mr. T. Bennett, of Trenton, N. J., who by his sensible papers on the destruction of vermin, shows that he has given close attention to, and thoroughly understands his subject, tells us that he has discovered something which is utter extermination to the mole.

He believes there should be some method whereby horticultural inventors should be secured in a good share of the profit which the public derives from the inventions for their benefit, just as other inventors are secured by patents. So do we. We were opposed to the efforts to get patents for new flowers and fruits, simply because we could see no way to make such efforts practicable. There is no more reason why one who has a good horticultural idea should not be paid as well as one who has an improved idea for an additional thread in a screw, or for a new steam engine. Anything new and useful which can be clearly defined and made tangible, so that any clerk can refer to the record and see just what it is, should be protected.

Unfortunately in horticulture and agriculture there are numberless ideas of great value which cannot be thus clearly defined and made matters of record, and for this reason only can no legal protection be given. Possibly a mole destroyer could be patented either as a " patent medicine " or a " patent trap." But in the absence of particulars it is impossible to say.
