1806.] Experiments in the Culture of Wheat 227

or a half sheet monthly, I shall do s0 with the greatest plea- Sure.

The seed-wheat used in the following experiment was as clean as any Ll ever saw; not a single smut-ball appeared on the surface of the water in which it was immersed. I have every reason to believe that it was free from infection, and that from such seed a crop of pure wheat may be obtained without any preparation. My disorder, however, is remind- ing me that I am at present unable to pursue this important subject; 1 shall, therefore, leave it in the hands of other cor- respondents, particularly in those of Farmer Sandy, who seems a powerful advocate for the judicious practice of pick- ling. 1 must also beg leave to refer to my letter in your 77th Number, which, if my memory is not defective, is greatly strengthened by this experiment.

s I am, Sir, Your most obedient servant,
