 Milwaukee or Chicago. In some potato sections 

 the farmers have organized and have warehouses 

 of their own. They hire a man at a salary to 

 handle the stock and ship direct to commission 

 houses in the large cities. 



"A good many progressive growers in this state

 as 300 bushels the profit should be increased pro- 

 portionately. There are a good many growers 

 on the light, sandy soils who do not average a net 

 profit of $25 per acre.

"A system of rotation in this state has been
