Tractor v. Horse

While the horses are returning to the roads they are being displaced on the fields. I watched a fine pair of Polish horses (which grow popular on English farms) begin to plough in some mustard flourishing on a field that was grass four months ago: they cut a few furrowi and then desisted. Word had come that one of the ploughing contractors could, after all, send the tractor and many-furrowed plough which had first ploughed up the grass. He would do the work very nearly as well and in one-sixth of the time. The provision of tractors for such work has been successful and, I suppose, there never has been a time when so many tractors are pulling so many multiple-furrowed ploughs. Some of the best of these ploughs have dispensed with the old knife-shaped coulter in favour of a cutting revolving disc which does not clod and so re- lieves the ploughman of carrying the spudded stick that was a necessity in any sticky or weedy soil.
