hard to keep from sprouting in the latter part of winter, and the 

 late kinds keep the best. 



Starch. — When potatoes are low in price, they can often be 

 profitably worked into starch, but for this purpose starch fac- 

 tories must be near by. Such factories are not expensive and 

 should be more common in this section. 



The demand for potatoes seems destined to increase very 

 much. There is a growing demand each year from the eastern 

 and southern states for northwestern grown potatoes. Under 

 ordinary cultivation, in this section, they seldom yield more than 

 150 bushels per acre of marketable tubers, and the average even 

 in favorable years is probably not over 120 bushels per acre. 

 There are, however, recorded yields here of 800 bushels per acre, 

 and they often yield over 400 bushels.

Varieties. — There is a very great difference in varieties, but 

 many kinds closely resemble one another. There is quite a 

 difference in the adaptability of varieties to soils. The large 

 coarser kinds are good for starch but not desirable for table use. 

 Most markets prefer a white or pink potato, rather long, oval in 

 form and smooth, but the fashions change and vary considerably 

 Some of the varieties at present regarded with much favor are 

 tbe following:
