In these results, the mulch system is first in yield and size of 

 apples, second to sod on color, and second to clean tillage by a 

 slight margin or growth.* It has surpassed the cover crop method 

 on every phase and in total ranking is plainly first thus far in the 

 combined results of this group of experiments. Reserving judg- 

 ment on the relative merits of these systems for the present we may 

 turn to consider the data from a similar experiment in an older 

 orchard — that of Mr. Fassett, in w^hich the trees are now thirty- 

 seven years old. The results from the unfertilized plots in this 

 orchard are shown in Table VII. 



•The margin Is really slighter than appears In the table, as the 1909 measurements in the mulch 

 plot of •xperlment 218 wer« taken a little higher on the trunks than those of 1907, owing to the 

 presence of screen on the trees at the later date.
