The effects of water as manure, is totally unknown all over this diſtrict, though it is perfectly well aſcertained, that there is none more efficacious, when properly applied. Along the banks of the Thames and the Colne, there are extenfive tracts of ground, which might thus be brought, at a fmall expence, to the higheſt pitch of pro- duce. It is faid that the greateſt part of Hounſlow heath might thus be improved. Amongſt the other advantages of watering ground, it is not the leaſt, that the neceſſity of making uſe of any other manure, on the ground thus treated, being totally obviated, the farmer is thence enabled to make uſe of all the dung which his farm produces, in

che enriching of his other fields.

On the banks of the Thames, particularly near Fulham, there are extenfive meadows, which ought to be embanked, being, comparatively ſpeaking, of very little value at pre- ſent, in conſequence of their being ſo frequently over- flowed by the river. They ſometimes produce at the rate of three load of hay per acre, at one cutting; but of ſo coarſe a quality, as not to ſell for half the price of common meadow hay. Such land, at preſent, is hardly worth 40 fhillings per acre; which, were it embanked, and laid out in garden-ground, would, in conſequence of the natural moiſtneſs and richneſs of the ſoil, and the cheap carriage of manure by barges, fetch L.4. and even upwards. The expence could not be great, as neither the tides, nor land- floods, are very ſtrong.

The mixing of ſalt with the food given to cattle, and other forts of animals, in all poſſible ways, ought to be particularly recommended both for preſerving the health of the animal, and, in the caſe of milch-cows, for improving
