extremely tenacious. Very few stones were encountered in ‘ne 
first two feet. In one corner of the excavation, where the ground 
had been ploughed in spring but not afterward worked, the soil 
was very perceptibly moister than elsewhere, to the depth of at — ip 
least two feet. Ata depth of two and one-half feet a layer of y 
dark colored gravel mixed with very tough clay was encountered. 
At the depth of five feet this changed to a tough yellow lay)

The soil used in filling the other two lysimeters (Nos. 3 and ays 
was taken from the surface of the open part of the west garden, — 
between the old apple orchard and railroad cut. The dry clods — 
were picked up early in August, after a month of dry weston 
sifted through a sieve of ian meshes to the inch. Sand for the 
bottoms was thoroughly washed, and was fairly dry when usede 
| At the time of filling (August thirty-one), a sample of the 
i sand for lysimeter No. 4, three feet deep, was dried and found to — 
+ gontain .126 per cent of moisture. A depth of six inches of this _ 
sand, weighing 221 pounds, was put in the bottom; then a depth 
‘ of three feet of the sifted soil was put in. This weighed i 
pounds. A moisture determination in duplicate showed 4.05 ed) +f
