this same thermometer registered 102°; at 11.45 a. m., 105°; at 3.10 

 p. m., 107°, and at 9 o'clock the morning of the 27th, 115°, an increase 

 of 28 degrees F. in 48 hours. The highest temperature registered on 

 April 27 was 133° F., in corner No. 4, 8 inches below the surface of 

 the corn. In corner No. 1, 14 inches below the surface, the tem- 

 perature was 110°; in corner No. 2, 112°; in corner No. 3, 125°; and 

 in corner No. 4, 132^°. Thermometer B, in corner No. 2, the same

 minimum air temperature, and the precipitation from February 17 to April 27, 1909. 



A clearer understanding of these contlitions will be had by consult- 

 ing figure 2, which shows the temperature of the corn in various parts 

 of the bin, together with the daily maximum and minimum air tem- 

 perature, and the general character of the precipitation during the 

 69 days covered by the experiment. 



CONDITION OF THE CORN AT THE END OF THE EXPERIMENT. 



As shown in figure 2, the only marked increase in temperature was 

 in the 6 or 7 feet of corn at the top of the bin. The maximum tem- 

 perature registered by thermometers No. 6 and A, approximately 12
