The tables show inconsistenoieB indicating that 

 the samjlbB should be composite. Some of the differences 

 might have been eliminated by determining the moisture 

 content from the soil in the cylinders rather than from 

 that from the side of the holes from which the samples 

 were taken. 



The Specific Gravity (Tables "B" and "C" shows 

 an irregular tendency to sligjhtly increase from plats 

 1 to 13. Plats 10 and 22, which represented almost the 

 extremes in production capacity and presumably ^of tex- 

 ture, had a slightly higher specific gravity than any of 

 the other plats. There seems to be no correlation either 

 direct or the reverse between the specific gravity and 

 the productive capacity. 



The pore space column X Table "C" is imiformly 

 smaller than that in column VIII . While column X was 

 calculated by the more direct method (formula 2, page ^147) 

 it seems that some of the water was lost by transferring the 

 sample to the scale pan. 



Comparing the samples taken November Spth. and 

 21st. (Table "D", III and V) both calculated by the in- 

 direct but more dependable method, it will be noted that 

 those taken November 20th. at the end of the plats imme- 

 diately after a thaw had less pore space than those taken 

 the next day from the middles of the plats. Since nfe
