years' old trees mostly with a view to trying the eli'ect of lime 

 together with artiticial manure on light soil, and the various blocks 

 I'eceived different quantities of kainit, basic slag, bone-meal and 

 superphosphate with and without lime. 



This experiment was started in April, 1915. 



With the exception of the blocks receiving lime and kainit 

 separately and also those receiving the two stuft's mixed, all the 

 blocks have gained on the check-blocks. 



Lime, as a whole, seems to have done more harm than good, as all 

 the blocks to which manure only has been applied show better 

 results than those receiving lime as well. 



• Kainit does not seem to have had any eifect at all and the 

 blocks manured with this stuff are losing on the check- blocks. 



The best result is shown on the blocks receiving bone-meal 

 at the rate of 400 lbs. per acre, but the effect of the same quantity of 

 superphosphate is not far behind. The effect of basic slag and the 

 smaller quautites of manures is less apparent, but it is quite 

 satisfactory. 



At the time the manure Avas applied the trees were very 

 retarded in growth. The improvement from them until now is very 

 marked, and some further effect from the slow-acting manures is 

 still to be expected. 



Altogether, 50 plots of two acres each were experimented with.

The experiment on the old trees was carried out on decidedly 

 over-tapped and backwai'd trees. It was commenced in November, 

 1915, with the double object of impn)ving the growth of trees and 

 iiupi"oving the yield.
