Along streams. Extensively cultivated in St. Joseph and Wayne counties 

 for the oil. Michigan produces about two-fifths of the world's crop. 

 St. Joseph county leads in production, followed by Wayne county, and 

 then by Wayne county, N. Y., which is the only other locality in the 

 United States where peppermint is grown to great extent. The annual 

 production in Michigan varies greatly, ranging from 20,000 to 60,000 

 pounds of oil. Some growers estimate the yield, in exceptionally favor- 

 able years, as high as 75,000 pounds. In severe seasons the plants are 



very apt to winter kill.— T. F. W r ood, et al.
