three and one half feet from the bottom, and remained near 

 the surface over night; heating had begun. The maximum 

 was at the second reading September 16, when it was 100.4°. 

 From that date it fell very slowly till February 17, when it 

 was 76°. 



Electrode No. 4 was placed in silo No. 2 September 15, in 

 the middle of the day's cutting, about thirteen feet from the 

 bottom. This electrode showed a very gradual rise from 77° 

 at the first reading to a maximum of 103° October 29; then a 

 more gradual fall to 98.6° February 17. 



Electrode No. 5 was placed in silo 2 the same day as No. 4, 

 about four and one half feet above it, and one and one half 

 feet below the surface. This was the end of the filling. The 

 surface remained uncovered for several days and was then 

 covered for perhaps a foot in depth by litter. This electrode 

 showed a rapid rise to a maximum of 127.4° five days after 

 installation; then a gradual (but less uniform than in case of 

 the other electrodes) fall to 96.8° January 14.

Observations have been continued, as during previous years, 

 with Edwin P. Jewett, New Hampshire College class of 1901, 

 acting as observer during most of the year. 



Signal flags, indicative of the weather for the succeeding 

 night and day, have been displayed from 11 a. m. until sunset 

 each day except Sundays and holidays, throughout the year. 



The reading of the wet bulb thermometer has been continued 

 throughout the growing season. The summary for the year 

 gives comparisons of temperature, pressure, and precipitation, 

 with averages of five full years. These averages now cover a 

 sufficient period to be of considerable value. 



The precipitation for the year has been normal, but the con- 

 centration of one third of the total into thirty consecutive days,
