FERTILIZERS. 521 



The conelnsions drawn from the experiments are as follows: 



(1) The iutiueuce of the bone mciil is largely dependent on its degree 

 of fineness. 



(2) Raw bone meal may, if very fine, give even better results than 

 extracted bone meal. 



(3j Thomas slag is more inferior to bone meal in its effects than is 

 bone meal to superphosphate. — P. w. woll.
