412 On eſtabliſhing Principles in Agriculture.[June

Should the Farmer, however,“ have ſtri@ly followed the above inſtrudions, and notwithſtanding the Moles ſtill continue te work about his land, he may be certain they have forſaken the run on which he has ſet his trap, and he muſt therefore ſearch for their new one.

The advantages ariſing from uſing traps on the‘above con- frudtion are, that the materials are to be procured every where; they can be made by any common mechanic at a very ſmall ex- pence,(the wood being uſed rough as it is comes from the ſaw,) are very durable if made of oak; are not liable to get out of re- pair, and if they ſhould, can be mended moſt probably by a la- bourer; they catch the whole year, and do hot require looking after more than three or four times in that period, and that will comparatively require ſo ſho a time, that a workman may with eaſe look over all tle traps on a very large farm; and, ſuppoſing the fields to lie contiguous to each other, one trap for each ten acres would, on an average, be fully ſufficient.

“< Be, therefore, will enter upon this great ſubje& of vezeta« tion, with a deſire to know ſomething—muſt firſt conſider the caufes and attributes, with the combinations of Earth— Salt— Water. The dews of evening, night, and morn, with the warmth and ſpring contained in the ſeed, and energy of the plant itſelf. Whether fermentatioh being other than a ſpecies of motion; whether there may not be divers, ariſing from the di-

‘verſity of ſalts, or other ſubjedts.

€ Whether nutrition(for increaſe) be not diſpoſed, more or leſs, to take to this or that figure. Theſe are ſome of the Ins ſtitutes in Huſbandry, y
