WM. DARLINGTON, _V. Prest._ ISAAC SHARPLESS, _Sec'y._ ON THE CULTURE OF TURNIPS. Turnips for fall and winter use are generally sown in the last of July. I have been long apprehensive that this sowing was too early. The weather at this season of the year is generally very hot and very dry; and drought has a direct tendency to dwarf and spoil a field of young turnips; the black fly, also, a natural enemy of the turnip, is at this period very voracious, and the crop is too often destroyed, or rendered unprofitable from one or the other of these causes.
