The remaining three acres were fown on rather light land after turnips. The whole fown on one ploughing, and houfed early in September.

The refult of the Doctor's extenfive experience on the cultivation of{pring wheat, is as follows:—1. That it is a diftinét fpecies ef wheat, as obferved by Columella, Linneus, and Ray. He has fown it in{pring, atthe fame time, and in the fame field, with common wheat. The common wheat failed, while the fpring-wheat rofe to a crop. 2dly, That being liable to be hurt by the froft, no advantage is gained by early fowing.‘That though the proper feafon may‘be about the middle of April, yet it may be fown fo late asthe 15th ef May, ashe found by experience laft year, when, notwithfianding the unfavourable feafon, it ripened before barley fown at the fame time, and on the fame field, and was cut on the 2oth of Septem- ber, immediately after the autumn-fown wheat; the crop two quarters per acre. 3dly, That about two bufhels may be the proper quantity of feed per acre; when drilled, lefs; his has been fown broad-caft. That the average produce may be about two quarters per acre, unlefs when fown after turnips fed off by fheep, when he has gained three quarters per acre. 4thly, That the average value may be about 1s. lefs per bufhel than the common wheat. He fold this year the fpring- wheat at ros. while r1s. was given for the common fort. 5thly, That being a fmaller grain than the common wheat, it ripens earlier and with lefs fun: in a wet harveft, therefore, it dries fooner for grinding, as he experienced laft year. That it receives but little injury from a wet fummer and autumn, but will ripen earlier than barley in fuch a feafon. And, 6thly, That when harrowed in on autumn-fown wheat, in places where the crop has failed, it will ripen at the fame time without injuring the fample; which wouid not be the cafe with either barley or oats. It may therefore, he thinks, on a large farm, deferve the attention of the hufbandman, and be worth his while always to cultivate a{mall quantity, as the beft means of reftoring a thin wheat crop.—Magazan beans, when dibbled in, will anfwer the fame purpofe, but perhaps not equally well, as they may be longer in drying than the wheat*.

But though Dr. Wilkinfon recommends the Triticum eftivum as beft adapted for{pring culture, Dr, Pike thinks that in fome northern parts of the ifland, where the common wheat is generally found to fail when fown in fpring, it may probably be fo: but continues his affertion that he has repeatedly fown both the common red or Kentifh wheat, and the white, iz the fpring, and had excellent crops. Dr. Pike has not, however, mentioned the nature of his land,
