acre. The sugar content is high and this soil is probably the best 
sandy soil upon which to grow the crop. Care should be exercised 
to provide perfect drainage, and to maintain the organic matter 
content of the soil. The beets should be grown but one year upon 
any given field, as crop rotation is essential to obtaining the best 
yields. 
Early Irish potatoes give fair yields of tubers of good quality. 
The yields range from 100 to 150 bushels per acre. In growing the 
potato crop perfect drainage is essential to success, as otherwise 
danger from blight and scab is great. The use of large quantities of 
high-grade commercial fertilizer is requisite. The most successful 
potato growers use as much as 500 to 1,000 pounds per acre of a fer- 
tilizer which analyzes about 2 to 3 per cent of nitrogen, 8 to 10 per 
cent of phosphoric acid, and 7 to 9 per cent of potash, derived prefer- 
ably from sulphate of potash. Frequent shallow cultivation is re- 
quired during the earlier part of the growing season. The spraying 
of the crop to reduce damage from blight is not common, but should 
be generally adopted upon this low-lying and moist soil type. 
In the vicinity of some of the larger cities, where the local mar- 
ket is good, other market-garden crops are grown upon the Clyde 
sand. Cabbage, onions, cauliflower, tomatoes, cucumbers, and string 
beans are thus produced in the vicinity of Saginaw, Mich., and the 
crops obtained are very profitable. Only a small area of the Clyde 
sand has yet been utilized for such crops and the extension of market 
gardening upon the type is dependent chiefly upon increased market 
outlets rather than upon the development of unused areas of the 
soil. Many thousands of acres may be used for these intensively 
farmed crops when the demand arises. A field of onions on the 
Clyde sand is shown in Plate I, figure 1. 
The Clyde sand may be characterized as a soil fairly well suited 
to the growing of general farm crops where drainage has been in- 
stalled, for pasturage where drainage is only partial, and for the 
growing of market garden crops and sugar beets where the local 
market for these crops exists and where the type has been completely 
drained. 
There are thousands of acres of this soil which are but partially 
reclaimed at present and which constitute a reserve of easily worked, 
special-purpose farm land still awaiting utilization. 
In general the farm equipment upon the Clyde sand does not differ 
materially from that of the general region where it is found. The 
market-garden farms are usually of rather small area and are 
frequently only equipped with a small residence and with sheds or 
small barns for the housing of work stock and tools. The general 
farms upon the type are usually improved with the larger house 
and the large barns common to the grain and dairy farms of
