supplying all the necessary constituents of plant-food much more 

 abundantly than did the artificial manure, but in a less available 

 form, produced only 52 lbs. more fruit per acre than did the nitrate 

 of soda alone, thus showing that only a small proportion of the 

 nitrogen of the farmyard manure was in a sufficiently assimilable 

 form to be taken up by the tomatos, in their short period of 

 growth. 



Table IX. shows experiments on peach trees at New Jersey. 

 The variety selected was " Crawford's Late." 



The results give the yield of peaches per acre of 130 trees, in 

 each of the five years 1887 to 1891 inclusive, and the total yield 

 of fruit for the five years. The quantities are given in number 

 of baskets of fruit per acre. Nine plots are quoted : No. 1 

 without manure ; Nos. 2 to 8 with various artificial manures, 

 applied either alone or in combination ; and No. 9 with farm- 

 yard manure.

This experimental orchard was planted in April 1884, and I 

 understand is still going on. The most recent report to hand says : 

 " The trees on most of the plots are looking well for trees of their 

 age, and that the differences between plot and plot are becoming
