Both manures have decreased it. The decrease averaged about 3 

 per cent, in the old orchard and 20 per cent, in the young. 



This decrease in color is probably simply due to delayed ma- 

 turity, the effect being greatest in the young orchards because their 

 general response to fertilizer has been greater. Had picking been 

 delayed a fevr days on the manured plots, it is quite likely that the 

 differences in color would have vanished.

Tables No. 8 and No. 9. shows results of the past season in regard to 

 the effect of soil systems and manures on the average size of apples. 



Both manures and tillage-with-a-cover-crop have increased the size 

 of the fruit. This is desirable in old orchards, but rarely so in young 

 as the fruit in the latter is already likely to be overgrown.
