FERTILIZER TESTS. 



The tests of fertilizers upon potatoes were the same as in the season of 

 1891, using the same plots and the same fertilizers for the first twenty- 

 plots. 



Each plot is one rod wide and four rods long and contains four rows of 

 potatoes. The rows are three feet apart, thus leaving seven and one half 

 feet space between the nearest rows of adjacent plots. This space is occu- 

 pied by young pear trees. 



Plots twenty-one to twenty-four were in potatoes in 1891, but did not have 

 any special treatment. 



Four plots are in a row, thus — plot two is alongside of plot six, etc. 



The fertilizers were applied in the row both above and below the seed. 



The planting was done on May 27, and the digging and weighing was 

 commenced on September 8.
