Weeds on walks are often the most troublesome. Wherever a loose shingly grav3l is used, or one that does not bind, hoeing and raking are permissible; but it is very undesirable in the case of walks, like those about London, which bind thoroughly, and when well made and dusted over with a little shell are the best walks known. If the traffic is not sufficient to keep them free from weeds, they must be either salted or hand-picked. Salting is the best plan, but it cannot well be applied where there are Box or other living edgings, as of course the first heavy rains will place the roots in a medium about as congenial to their wants as if they were planted in the salt sea. If walks are well gravelled, picking them is not a very troublesome operation; but after a season or two the gravel gets infested with a myriad of small weeds. Human patience has not been made sufficiently elastic to enable us to pick out these, and therefore such must be turned over in spring, and a coating of new gravel applied.

Salt may be applied to walks cut in the turf.
