PIRATE 15 
A. —The control plot in the experimental field of Reid Yellow Dent at Linden, Ind., 
in 1920. In 1919, rootrot was very severe in this field. Note the stunted growth. 
B. —This plot received an application of acid phosphate at the rate of 300 pounds 
per acre and limestone at the rate of 3 tons per acre. Limestone applied alone at 
the rate of 3 tons per acre caused injury to the plants in the limestone plot. Pictures 
A and B were taken on the same day.
