Average weight of the seven varieties of these green trees was — 
970.3 grams each. With rows four feet apart and trees one foot ~ 
apart in row there would be on an. acre 10,890 trees, weighing ~ 
23,299 pounds, or over eleven tons. The average of the thirty-one 
trees gives 1.80 per cent. of ash in the green tree, therefore there 
would be 419.4 pounds of ash removed by an average acre of nur- 
sery stock. 
Quantitative analyses have been given of the ash of these trees, 
and the average of these, which do not widely differ in. composition, 
shows that 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:
