bushels on 80,000 acres. In the Lake Superior coun- 

 try, clover seed is represented as difficult to secure 

 in good condition because rain is likely to occur in 

 the harvest time. It is grown in marketable quan- 

 tities in Ontonagon County. 



VEGETABLES 



Michigan produced nearly 29,000,000 bushels of 

 potatoes in 1919, and 35,700,000 in 1920, which was 

 8.3 per cent of the United States crop. They are 

 of predominant importance in certain portions of the 

 State, particularly in the central counties of the 

 northern Lower Peninsula and in Marquette, Me- 

 nominee, Delta and Houghton counties in the Upper 

 Peninsula. Thus, in 1919, the counties producing 

 more than 1,000,000 bushels in the southern penin- 

 sula were Mecosta, jMontcalm, Osceola, together with 

 Oakland in the southeastern section ; while in that 

 year Houghton County led the Upper Peninsula with 

 a yield of 650,000 bushels, followed by Menominee, 

 Delta, and ]\farquette counties. Montcalm's product 

 of 2,381,730 bushels led the State. With potatoes, as 

 with other products of the soil, the tendency has been 

 to eliminate many varieties in favor of a few types 

 of approved quality. The report of the Michigan 

 Board of Agriculture for 1868 lists fifty-five varieties 

 of potatoes with the yield of each as determined ex- 

 perimentally. In this list the now long-forgotten 

 Chenery topped the production record with 353 

 bushels to the acre. The average yield in 1920 was
