Immediately after dung has been spread out in the hollowdrills, the ridgelets are split open to cover it; and the seed isinstantly sown, to preserve the natural moisture of the soil asmuch as possible, that the seed may spring quickly and equal-ly. In districts where considerable quantities of turnips arecultivated, a compound drill-machine is used, which sows twodrills at once, and is connected with a light roller foB flatten-ing the tops of the drills to exclude drought. Single rowdrill-barrows are still to be seen in many places.

As the land for the grain crop which follows turnips, whe-ther barley, oats, or wheat, seldom gets more than one plough-ing, it is customary to lay off the turnip drills, in a directionsomewhat different from that in which the ridges are to be af-terwards drawn for the grain crop. By this a more equabledistribution of the manure is made through the soil for nou-rishing the ensuing crops of grain and grass.

6. The sorts generally cultivated are the white-topped Nor-folk and the Globe. Sometimes the seed procured from Eng-land has a mixture of green or red topped among the white.Several persons, in different districts, are at great pains toraise seed of selected varieties, mostly, however, white globe,for sale; to which some men have chosen to give peculiarnames of their own contrivance. The tankard variety is some-times cultivated for early use, but it is believed not to bearthe vicissitudes of winter equal to the others already mention-ed. A new variety, called the yellow field turnip, has of latebeen recommended in some districts, as peculiarly well calcu-lated to stand the winter, and to serve for late spring feed,when the white kind is over. “ This variety is quite differ-ent from the yellow garden turnip, being larger, containingmore juice or nutritive substance, more easily cultivated, andpreserving its feeding powers till the middle of May, whenthe grass season may be expected to commence. Upon ordi-nary soils, it is superior to ruta-baga, because it will grow toa considerable weight where the other would be stunted orstarved, and it stands the frost equally well. The mode of
