Average weight of green trees was 924 grams. With rows four 
feet apart and trees one foot apart in row there would be on an 
acre 10,890 trees weighing 22,183 pounds or eleven tons. The 
average of the thirty-one trees gives 1.80 per cent of ash in the 
green tree, therefore there would be 399.3 pounds of ash removed 
by an average acre of nursery stock. 
Quantitative analyses have been made of the ash of three apple 
trees, four cherries and three pear trees, and the average of these 
ten, which do not widely differ in composition, shows that, upon 
an average, there is taken from the soil in eleven tons of nursery 
stock the following mineral constituents, each having been deter- 
mined except the carbonic acid of the ash:
