For the purpose of comparison the following table is presented 
giving the number of pounds of the several mineral constituents 
removed by a ton of the grain and of the straw of each of our 
principal cereals, from which it will be seen that since, upon an 
average, it requires from three to four years to grow the crop of 
nursery stock, the cereals make a far greater demand upon the 
soil than does the growing of nursery stock, and it is a matter of 
common observation that the removal of a crop of trees leaves the 
soil in excellent condition for the growth of the cereals. 
It is proposed to complete the ash analyses of the remaining 
portion of the trees, and also make analyses of the fruit of each 
variety during the next season. j
