[AL] Field rollers should be made in sections, for ease of turning.
[AM] The beneficial effects of mulching is so great as to lead us to the conclusion that it has other means of action than those mentioned in this book. Future experiments may lead to more knowledge on this subject.
[AN] It is possible that the excrementitious matter thrown out by some plants may be sufficiently destructive to other kinds to exterminate them from the soil—thus, farmers in Maine say that a single crop of turnips will entirely rid the soil of witch grass. This is, undoubtedly, the effect of the excrementitious matter of the turnips. This subject is one of practical importance, and demands close investigation by farmers, which may lead to its being reduced to a system.
