The following are such as are perennial, and are of the most troublesome nature, being xtremely difficult to get rid of in consequence of their creeping roots. It unfortunately appens that, where the land is the most worked, and the roots the more broken thereby, the more the crop of weeds increases on the land. Therefore, the only effectual mode of extirpating plants of this nature, is by picking out the roots after the plough, or by digging them up at every opportunity by some proper instrument. Where weeds of this nature occur, there is too often thought to be more labour than profit in their extirpation. And although this is an argument of some propriety, where a farmer is tenant at will, or where his strength is not proportionate to the land: yet if land is worth any thing at all, that, whatever it may be, is lost, if it is suffered thus to become barren. And as prevention is in most cases considered preferable to cure, more care ought to be taken than generally is, of all our hedges and waste pieces of land by road sides, &c. Many of these plants are found growing in such places, and their seeds are of that nature that they are calculated to fly to considerable distances,--a contrivance in nature to fertilize the ground in her own way; but which, as agriculturists, it is the business of men to check. 706.
