One pound of Snow-Flake, planted in single eyes, yielded 59^ 
pounds. Its season is stated to be the same as that of the Early 
Rose. With us it ripened one week later. The quality is excel¬ 
lent. 
Brownell’s Beauty is a late variety of excellent quality. Three 
pounds seed, cut to single eyes, yielded 123 pounds; ripened Sep¬ 
tember 16. All varieties planted May 9.

The number of varieties in cultivation has been greatly dimin¬

IMPROVEMENT OF SOILS BY MECHANICAL MEANS. 
This experiment was begun in 1871, upon four adjacent plats of 
an acre each, to be cultivated as follows: 
Plat 1, to be plowed to a depth of five inches only. 
Plat 2, to be plowed twelve inches deep. 
Plat 3, to be plowed twenty inches deep by trench plowing. 
Plat 4, to be plowed twenty inches deep by subsoiling. 
Plats 1 and 2 have been cultivated in the prescribed manner from 
the beginning. 
Plat 3, in 1871, was plowed twelve inches deep only; in 1872 and 
1873, seventeen inches, and in 1874, eighteen inches, which is as 
deep as it has been found practicable to plow. 
Plat 4 was subsoiled sixteen inches deep in 1871; seventeen 
inches in 1872 and 1873, and eighteen inches in 1874. 
The cultivation of these plats has been the same in all other re¬ 
spects than those mentioned. 
The soil is clay, with heavy clay subsoil; the land is level and 
rather low. In the fall of 1873, an underground drain was laid
