method by which these lands may be brought to their full producing 
capacity. 
Drainage still remains so imperfect over considerable tracts that 
the farm buildings are located upon the sandy elevations which rise 
above the general level of the plain. Many local swamps persist 
and the peat areas have been but recently drained. Both fronTthe 
standpoint of profit and of health drainage should be extended and 
rendered mere complete. 
The crop adaptations of the Clyde fine sand vary considerably in 
the different areas where it has been encountered. In the most ex- 
tensive area, in Xewton County, Ind., the crop uses vary chiefly with 
the proportion of organic matter found in the surface soil and with 
the depth of the dark-colored surface soil. Those areas in which 
the organic matter content is rather small are chiefly devoted to 
pasturage, while the areas well supplied with vegetable remains to 
a considerable depth are used for the production of general farm 
crops. 
Corn is the principal tilled crop grown. It is reported that in 
the early days of the occupation and cultivation of this soil the yields 
secured were as high as 50 bushels per acre. It is now estimated 
that the average yield is about one-half of this amount. Present 
yields range from 10 to 35 bushels per acre. Corn is grown for one 
or more years and the land is then seeded to a small grain crop, al- 
most always to oats. Oats yield from 20 to 30 bushels per acre. 
In the usual rotation the field is next seeded to grass. Timothy is 
commonly sowed alone as clover is likely to be winter killed on the 
level and partly drained land. It is probable that redtop and meadow 
fescue could be added to the seeding mixture with profit where it is 
intended to cut the hay for home feeding and to follow several years 
of hay production by the pasturing of the fields before they are again 
plowed for corn. It is also certain that alsike clover may be profit- 
ably seeded with the grasses where the land is fairly well drained. 
When clover is to be seeded the Clyde fine sand would be greatly 
benefited by the application of 1 to 2 tons per acre of finely ground 
limestone rock. This should be applied when the seeding to grass is 
made, usually with the seeding of the oat crop. It would also benefit 
both the oat crop and the grass seeding to apply finery ground raw 
phosphate rock at the rate of not less than 500 pounds per acre at 
the time of oat seeding. It has been demonstrated, also, that all 
crops are greatly benefited through the application of muriate of 
potash or kainit to such soils as the Clyde fine sand, especially where 
the content of organic matter in the surface soil is unusually high. 
Proper liming and fertilization should greatly increase the yields 
of all of the general farm crops. Where possible, stable and yard 
manure should be applied to the corn ground.
