The results of the observations on soil moisture are recorded in the 

 following table: 



Soil moisture. 



* 0.56 inch had fallen in the 30 hours preceding sampling. On the day of sampling, rain fell before 

 the hour for taking the sample in the following cases: August 9,0.02 inch; September 7 47 indi 

 September 13, 0,17 inch; Oitober 11, 0.01 inch; November 8, 0.42 inch. 



1 August 14 had a rainfall of 2,25 inclies. 



It is somewliat surprising to uotf that the average amount of moisture in the soil 

 this year was only 20 per cent while last year it was nearer 40 per cent, and yet the 

 rainfall during the period of observation was greater this year. No errors in 

 method or computation are discoverable. The samples were taken from the same 

 spot, the principal differences being apparently in the heavier rain showers l»y 

 which the earth might be compacted, the lack of heavy frosts during the preceding 

 winter making the surface of the soil less porous than if it had been heaved by 

 frost, as well as somewhat thinner vegetation.
