From the abstracts of statistical returns prepared at the American Census office, it appears that Pennsylvania, in 1850, was the largest wheat producing State of the Union.  I have had the curiosity to compare the most prominent States in respect to this crop, and give them below, with the crop of each, as shown by the returns:—­

Bushels. 
Pennsylvania          15,482,191
Ohio                  14,967,056
Virginia              14,516,900
New York              13,073,000
Michigan               4,918,000
Maryland               4,494,680

That the United States could export 6,000,000 bushels of wheat, and its equivalent in flour in 1845; 13,000,000 in 1846, 26,000,000 in 1847, and then fell back to 13,000,000 in 1848, and 6,000,000 in 1849, with their production of wheat constantly increasing throughout this period, shows a wonderful elasticity, and extensive home market.  If the price of wheat is higher in proportion than for corn, the Americans export the former and consume the latter; if the demand for corn be also great, they kill their hogs and export corn, for the pork will keep.  If there be no great demand for either, they eat their surplus wheat, feed their hogs with the corn, and export pork as having the greatest value in the least bulk.
