Creeping-rooted Weeds.

The following are such as are perennial, and are of the most trou-blesome nature, being extremely difficult to get rid of in consequenceof their creeping roots. It unfortunately happens that, where theland is the most worked, and the roots the more broken thereby, themore the crop of weeds increases on the land. Therefore, the only effec-tual mode of extirpating plants of this nature, is by picking out theroots after the plough, or by digging them up at every opportunityby some proper instrument.

Where weeds of this nature occur, there is too often thought to- bemore labour than profit in their extirpation. And although this is anargument of some propriety, where a farmer is tenant at will, or wherehis strength is not proportionate to the land : yet if land is worth anything at all, that, whatever it may be, is lost, if it is suffered thus to be-come barren. And as prevention is in most cases considered prefe-'able to cure, more care ought to be taken than generally is, of allOW hedges and waste pieces of land by road sides, &c. Many of thesePlants are found growing in such places, and their seeds are of thatnature that they are calculated to fly to considerable distances,—acontrivance in nature to fertilize the ground in her own way ; but»hich, as agriculturists, it is the business of men to check.
