LARGE PROFITS IN POTATOES 103 



kept around the growing crop for the purpose of con- 

 serving such moisture as there is. It is unwise to let 

 potato ground harden and bake in the sun. By giving 

 reasonable attention to the product along the lines indi- 

 cated success will be attained in almost any section of the 

 United States. 



Potatoes do well in rotation with clover, millet, corn, 

 beets, rutabagas, cabbage, etc. It is feasible to dig a crop 

 of early potatoes in June or July and then immediately 

 sow millet, rye or fodder corn on the same ground. It 

 is also a good plan to plant late potatoes on land from 

 which clover, cowpeas, rye or any other early crop has 

 been taken. 



There are sixteen states in which the cultivation of 

 sugar beets is already well established in this country. 

 Practically all of these states are large producers of 

 potatoes. More significant still is the fact, recently 

 brought out by an exhaustive inquiry, that the use of 

 sugar beets in rotation with potatoes, corn, wheat and 

 other crops increases the yield of every one of these 

 crops from 25 to 50 per cent. In the case of potatoes the 

 increase was 46.2 per cent. 



Early Rose, Triumph, Early Michigan and Early Ohio 

 remain standard early varieties, while some of the best 

 late ones are Burbank, Peerless, Peachblow and Green 

 Mountain. There are many variations in these types, but 

 for all practical purposes the potatoes can be recom- 

 mended as named above. 



It is necessary to be on guard against disease and insect 

 pests. A healthy growth of potatoes can hardly be ex- 

 pected on soggy land or where spraying is neglected. 

 Good seed is of the highest importance, and with this 

 point settled thorough cultivation will insure a crop five 

 years out of six. 



The potato scab is a disease that remains in the soil 

 from one year to the next as a fungus and if potatoes
