acre will be found to help clover, while for alfalfa 2 tons or more

The question of erosion is an important one on this type of 
soil and especially on that part designated as steep phase. In 
many cases the loss of organic matter and phosphorus from the 
soil by erosion is considerable, and often the fertility and yields 
on some fields could be greatly improved by proper attention 
being paid to the arrangements of the fields and crops and the 
protection of the fields from erosion. 
When the slope becomes so steep that the bare ground washes 
to any extent, care should be used to keep that field in hay or 
pasture as much as possible or it should be laid out in alternate 
strips of cultivated crop and sod land if practicable. Where the 
slope is so steep that modern farm machinery cannot be used, 
cultivated crops should seldom if ever be grown. When timbered 
such slopes should remain so and be used for pasture only. 
Badly eroded slopes can be restored by proper cropping and 
management. For further data on erosion see Bulletin 272 of 
the Wisconsin Experiment Station. 
Chemical analyses of Lintonia silt loam show it to contain on 
the average slightly more of the essential plant food elements 
than occur in Knox silt loam which it very much resembles in 
texture, structure, and color. Suggestions offered for the 
improvement and management of the Knox silt loam will also 
apply to this type of soil except as regards erosion. While this 
soil is eroded in some cases, the topography being level sheet 
erosion does not often occur, and methods for combatting gullies 
only are necessary. 
Lintonia Silt Loam. 
Description .—The surface soil of the Lintonia silt loam to an 
average depth of 10 inches consists of a brownish-gray, friable 
silt loam, which becomes lighter colored on drying and frequently 
has a whitish appearance. The amount of organic matter pres¬ 
ent in the surface soil is comparatively small, and this accounts 
in part for the light color of the material. A slight acid condi¬ 
tion has developed in places in the surface soil, as indicated by 
the litmus-paper test. The subsoil consists of a yellowish-brown 
or buff-colored silt loam, which usually becomes somewhat heavier 
and more compact with depth, and at 24 to 30 inches may be
