Correſpondent who ſigns himíclf a Warwickſhire Gra-

zier, has‘called the attention oí your readers to a very important ſubject of enquiry. The loſs which he has ſuſtained from the foot-rot, bas been ferious indeed. As my own ſheép ſuffered laſt year from the ſame d fo: der, though in an inferior degree, I feel myſelf intereſted in the diſcuſſion.

] attribute the diſorder among my Mock, to cotinuing in long graſs, which, during a mild winter, muit have retained a conſtant moifturc, and by keeping the ſoot wet may be conſidered as a cauſe predifpofing to the‘diſorder, if not a@ually to have occa= fioned the diſeaſe. LI have freguently ſed ſheep on the ſame land, without diſcovering any ſymptoms of the foot-rot. I have bought ſheep diſordered from other paſtures, which have been cured while feeding in my grounds; the diſorder therefore is not neceſianily conneélted with the land, and may have been oc- caſioned by the particular circumſtance of beiug kept all winter on the long gras. Perhaps the beſt preventive is to fold the ſheep. The flocks in this neighbourhood are principally kept by farmers who occupy common ficld-iand, and who conſtantly uſe the fold. Theſe, I ám informed, never fuffér from the diſ- order. L have known it prevail in Gentlemens” parks where the ſheep have only turf to tread on.

Suppófing it to ariſe from relaxation óccaftaged by the eon- ſtant application of moiſture to thé feet; another query then átiſes,“ Is it contagious?’ From its rapid progreſs, I believe it is, and the ſtate of the foot which 1s uncommonly offenſive and putrid, will eaſily give Credit to this ſuppoſition. The contagion
