Chaiiges which take place in the Field 



clover hay on plot 6 the quantity produced between the 9th and 

 30th of June — a quantity amounting to about 2\ cwt. — an acre 

 of clover yielded 3 tons and 2 cwts. of good hay, containing 

 16'7 per cent, of moisture. 



On plot 7, where the crop was mown on the 16th of June, 

 3 tons 6i cwt. in round numbers of equally dry clover-hay was 

 made. The further growth between the 16th of June and 28th 

 of July was at the rate of exactly 1 ton of fresh clover, or about 

 7|- cwts. of hay per acre. Altogether the yield of plot 7, esti- 

 mated as hay, came to 3 tons 13 cwts. and 100 lbs., which, it must 

 be admitted, is a very good crop. 



Moreover, on plot 7 we have the largest accumulation of nitrogen. 

 The nitrogen in the clover on the 16th of June here amounted 

 to 113 iV lbs. calculated per acre — a larger quantity than was 

 found at any of the other experimental mowings. 



According to the preceding results, the week in which the 

 16th of June fell appears to have been the most profitable period 

 for beginning the hay-harvest.
