THE CLYDE SERIES OF SOILS. 47 
then reseeding to alfalfa is more profitable than continuing the 
harvesting of the mixed hay. 
Winter wheat is a minor crop upon the Clyde clay, although it was 
formerly extensively grown. The yields are still above the average 
for the wheat-growing States, but the increased value of the land 
has rendered the production even of fairly large crops no longer 
profitable. Yields of wheat range from 15 to 25 bushels per acre on 
the Clyde clay. 
Within recent years sugar beets have come to be grown to quite an 
extent upon the Clyde clay. The tonnage secured is good, ranging 
from 10 to 12 tens per acre of beets of rather high sugar content. 
The beets are grown to best advantage where tile drainage has been 
established. They, may not be grown where drainage has not been 
perfected, at least by open ditches. A very uneven stand is obtained 
where drainage is neglected. It is probable that the Clyde clay is 
second in value only to the Clyde loam as an eastern sugar-beet soil. 
The acreage upon this type should be extended as rapidly as factory 
facilities are provided. 
Potatoes are grown on this type only to a very limited extent and 
chiefly for home use. Wherever another more friable soil is avail- 
able it should be used for Irish potatoes in preference. Yet yields 
of 100 bushels or more per acre may be obtained upon well-drained 
land. The tubers are likely to be rather dense and to cook to a dark 
color. 
It is apparent from the crop adaptations of the Clyde clay that it 
is a soil whose most productive crops are especially well suited to 
the fattening of beef cattle, the feeding of dairy cows, and the grow- 
ing and fattening of hogs. This type of farming is being gradually 
extended over the different areas of the Clyde clay, although the 
present dominant form is usually that of producing corn, other 
grains, and hay for sale. The fact that corn, mixed grasses, blue- 
grass for pasture, and even alfalfa, may be grown to excellent 
advantage upon this soil marks it as destined to become more and 
more a stockgrowing and dairying type. 
In all cases where the Clyde clay has been drained and used for 
tillage forms of agriculture the equipment of farm buildings is that 
of a prosperous general farming community. The dwellings and 
outbuildings are most commonly frame structures or the house is 
of brick. The teams used are among the heaviest and best of the 
Central States. The implements and machinery used are commonly 
of improved sorts well suited to the management of a stiff and re- 
fractory soil. Yet there are portions of the type where drainage 
is just becoming established where the old log house and barn still 
persist and where the improvements have not yet attained to the 
excellent condition of the longer occupied areas. There are still
