The series taken November 21st. waa also Immersed 

 in water for three hours, letting the water rise from beneath, 

 removed and immediately weighed in a scale pan. The pore 

 space for the series taken November 20th. (Table "B" Column 

 8) and November Slat. (Table "0" Column 8) was calculated 

 according to the following formula.

The pore space for the series taken November 21st 



(Table "C" Column V) was also calculated by the following

The specific gravity was determined with a pyk- 

 nometer from the samples used for moisture determination 

 in both series. The results from each series correspond 

 closely so the average of the two is used in the tables 

 which follow;
