it with oats, and prepared it for wheat, in 1804. In 1805 

 the stunt had increased considerably, and very much in- 

 jured the crop. In 1806 I became possessed of the field, 

 and by the practice I have adopted, I have never been 

 injured by the stunt there, but have made good crops, 

 at least of straw. 



II. A temporary cow pen, or feeding, yard, was made 

 in a field, for the purpose of feeding cattle through the 

 winter, (the common practice here) the fence enclosing 

 the pen was removed in the spring, the manure carted 

 to a distant part of the field, and the ground planted in 

 corn in April, and sown in wheat in October ; the corn 

 was very luxuriant, but the wheat on the area of the feed- 

 ing yard was intirely killed in March ; and what was very 

 extraordinary, I couldtracethe zigzag line where the fence 

 had stood, distinctly on the wheat. The disease had 

 not extended any further than the ground had been co- 

 vered by the litter in the cow-pen, which in the spring 

 was f perhaps two feet deep. This was the first appearance 

 of the stunt in this field. 



III. In one of my fields where water sometimes stands 

 after heavy rains, the stunt appeared a few years ago, on 

 a small spot about thirty feet diameter, and from that 

 spot has extended considerably. 



IV. In the winter 1804 — 5, a severe season for snow 5 

 and sleet, in one of my fields sown witty red-bearded wheat, 

 two small spots, distant from each other about two hun- 

 dred yards, were exposed for some time to very severe 

 frosts, the snow having been drifted from those places. 

 In March, the wheat began to perish, the ground soon 

 became bare, and, on examination, I found the wheat 

 was stunted, and the spots mentioned produced nothing
