1830. The crop of clover would have been considered excellent even 

 on good land, and was most remarkable for so poor a soil as this. The strips 

 sown through A, had but little left alive, and that scarcely of a size to be 

 observed, except one or two small tufts, where I supposed some marl had 

 been deposited by the cleaning of a plough, or that ashes had been left, from 

 burning the brush. The growth of clover was left undisturbed until after 

 midsummer, when it was grazed by my small stock of cattle, but not 

 closely. 



1831. Corn on the whole field. October 20th, measured carefully half 

 an acre (10 by 8 poles) in A, the same in D, and half as much (10 by 4) 

 in E. No more space could be taken on this side, for fear of getting within 

 the injurious influence of the contiguous woods. No measurement was 

 made on the side B, because a large oak, which the belting had not killed, 

 affected its product considerably. Another accidental circumstance pre- 

 vented my being able to know the product of the side C, which however 

 was evidently and greatly inferior to all the marled land on which oats and 

 clover had been raised. This side had been in corn, followed by wheat, 

 and next (1830) under its spontaneous growth of weeds. The corn on each of 

 the measured spaces was cut down, and put in separate shocks — and on 

 Nov. 25th, when well dried, the pai'cels were shucked and measured, before 

 being moved. We had then been gathering and storing the crop for more 

 than fifteen days— and therefore these measurements may be considered as 

 showing the amount of dry and firm grain, without any unusual deduction 

 being required for shrinkage.

The sloping surface of the side E, prevented water from lying on it, and 

 therefore it suffered less, perhaps not at ail, from the extreme wetness of 

 the summer, which evidently injured the growth on A and D, as well as of 

 all the other level parts of the field. 



1832. The field in wheat. 



1833. In clover, which was grazed, though not closely, after it had 

 reached its full growth. 



1834. Corn, a year earlier than would have been permitted by the four- 

 shift rotation. The tillage was insufficient, and made still worse by the 

 commencement of severe drought before the last ploughing was completed, 

 which was thereby rendered very laborious, and imperfect withal. The 

 drought continued through all August, and greatly injured the whole crop 

 of corn. 



Results continued. October 22d. Marked off by a chain half an acre . 

 within the space A (8 by 1 poles) as much in D, and a quarter acre ( 10 by 

 4 poles) in each of the other three sides C, B, and E, having each of the 

 last four spaces as near as could be to the outlines of the space A. The 

 products carefully measured (in the ears) yielded as follows :

In comparing these products with those of the same land in 1831, stated 

 above, it should be remembered that the corn formerly measured was dry, 

 while that of tiie last measurement had yet to lose greatly by shrinking. 

 As after early gathering, the corn from the poorest land of course will lose
