October and November — No. 4 increasing 155 lbs. and No. 5 

 176 lbs., while No. 3 increased only 114 lbs., and No. 2, 111 lbs., 

 which seems to favor the theory of those who suppose that the 

 late application of manure is useful, by affording a protection 

 to the roots of grass through the winter. But perhaps inferences 

 should be drawn with caution from a single experiment, which, 

 tried under different circumstances, might yield different results. 

 But should time and opportunity be afforded another year, the 

 result of this experiment the third year will be noted and com- 

 municated. 



Pembroke, November 10, 1846. 



George W. Wood's Statem>ent. 



The manure I used, to ascertain the best time to spread com- 

 post manure, was made as follows : — in the month of April, 

 1845, I made a pile of twenty-five loads, by mixing one third 

 green manure from the barn, one third muck, one third soil and 

 scrapings around the barn, tfec. About the 20th of May, I spread 

 five loads on one eighth of an acre ; in August, five loads on an 

 adjoining one eighth of an acre ; in September five loads ; in Oc-

 of an acre, and all adjoining each other. The soil was a clayey 

 loam, very near alike. 



I stocked the land down with oats and grass seed in April, 1842. 

 The 16th July, 1845, I weighed the hay on the one eighth spread 

 to manure in May ; it weighed one hundred and seventy-six and 

 one quarter lbs. Weighed, the same day, the hay on the one 

 eighth of an acre adjoining, no manure, one hundred and seventy- 

 one and one quarter lbs. In April, 1846, 1 made another compost 

 heap in the same manner and of the same materials as above 

 described, and I have spread the same land about the same time, 

 and in the same manner, as in 1845, up to this time. July 24, 

 weighed and got in the hay on the whole five eighths of an acre ; 

 made the hay three days ; where the manure was spread in 

 May, two coats of manure, the hay weighed four hundred and 

 forty-one lbs. ; spread, in August, four hundred and thirty-eight
