Wheat prices are more strongly influenced by "world" conditions than are prices of other staple crops, which 

 makes the fluctuations appear more irregular. The production in the United States in 1909 was 683,000,000 bush- 

 els; in X910 it was 635,000,000; in 1911, 621,000,000; and in 1912, 730,000,000.

There is an early crop and a late crop of potatoes; hence the seasonal variation of prices is not so regular u 

 with most crops. The crop of 1909 was 389 million bushels; 1910, 349 million; 1911, 293 million (very short): 

 and the crop of 1912, 421 million.
