Salt is sometimes applied to gravel walks and roads in a liquid state, or in the form of strong brine used quite hot, or as near the boiling point as possible. This is said to be very effectual in preventing the growth of weeds. Sundry other solutions are also recommended for the purpose. But I know of nothing more effectual than a liberal dressing of dry salt, sufficient to whiten the entire surface of the gravel. A slight sprinkling is of little use, and may even increase rather than diminish the evil which it is intended to cure. In applying such a dressing as has just been recommended, it is, of course, necessary to exercise caution, in order to prevent the salt coming in contact with the grass, box, or other plants, which may form an edging to the road or walk operated on. In my garden last year some walks which were salted early in the season have been free from weeds all summer. - Gardening Illustrated.
