From the fuccefs of the preceding experiment 

 on buck-wheat, as alfo of that for which I was 

 honoured with the Society's premium, and various 

 others which I have made for feveral years paft, it 

 is become with me a favourite objedl of cultivation; 

 being clearly of opinion, that it ought in numerous 

 cafes to fuperfede the practice of fummer fallow- 

 ing; for the crop produced feems not only to be fo 

 much ckar gain in refpedt to fuch pradice, but alfo 

 affords a confiderable quantity of ftraw for fodder 

 and manure ; befide that I think a fummer fallow- 

 ing is nothing like fo advantageous a preparation 

 for a fucceeding crop. From its quick and luxu- 

 riant vegetation, it is an admirable deftroyer of 

 weeds, and fuits with a dry, light, mellow foil, 

 but flourifties mod in a light fand. It is impatient 

 of wet and cold. 



The proper feafon for fowing I take to be from 

 the middle of May to the middle of June.* I 

 have fown it however fo early as the beginning of 

 April, and fo late as the 2 2d of July, by way of 

 experiment, but have found the latter extreme 

 rather to be chofcn. In another experiment, a 

 frnall piece of land brought to maturity the grain 

 of two different crops in the fummer of 1783. 



• The lad week of May, or the beginning of June, is ftill better ; 

 as the leaft froft will cut off the plants at their fiift appearance, it 

 being a native of a much warmer climate.
