applications as the ſood of animals. One cause of the little progres3s which has bcen made in the cultivation and use of this valuable root in Some districts, is probably that of too closely following the methods that have been long in prac- tice for the common turnip, as in Such modes of culture it can obviously never be raised either with benefit to the cul- tivator, or in any very perfect manner, as from its more com- , pact nature, it must evidently require a much greater length of time upon the ground to attain its full growth and state of maturity. It Should of course be 50wn at a much earlier period, as in the latter end of April or the beginning of the following month; but not by any means later than May; as in all the numerous trials I have made in raising crops of this Sort, 1 have never found that the roots attained any large Size where the Seed was put into the ground after that period.

Another circumstance which has materially retarded the cultivation of this useful crop, is that of the great difficulty of Procuring Such Seed as can be fully depended upon. This Inconvenience can probably, only be obviated in an effectuatl manner by the farmer providing his own sced, by transplant- ing a few of the best and most perfect roots, at the proper Seas0n, int9 a Situation where they may not be in langer of being injured by other plauts of a Similar nature, during the period of their fowering."The best roots are those which have a toughish green tbick cuticle or skin, with be internal feshy parts firm, and of a yellowish colour.

The fly has been found to be very destruetive of this crop, but wbich may, I have no doubt, be much prevented by the early 8owing that has been adviSed above, as I have never found much injury from this cause, when the Seed was put into the ground at ap early period, while at a late Season 1 have almost always experienced it to be the case. There is Jikewise attention necessary to the proportion of Seed, as it Should never be Sown in too Small a quantity for this Sort of erop, a Sufhcient plant being always desirable.

The preparation of the ground Should also be carefully at- tended, as well as that of keeping the plants clear, and the mould well broken about them, as upon the;e much likewise
