765-66, 54,205 bushels; in 1771, 259,441 bushels.

The total amount exported from America in 1770, was 573,349 bushels;
in 1791, 2,064,936 bushels, 351,695 of which were Indian meal; in
1800, 2,032,435 bushels, 338,108 of which were in meal; in 1810,
1,140,960 bushels, 86,744 of which were meal. In 1820-21, there were
exported 607,277 bushels of corn, and 131,669 barrels of Indian meal;
in 1830-31, 571,312 bushels of corn, and 207,604 barrels of meal; in
1840-41,535,727 bushels of corn, and 232,284 barrels of meal; in
1845-46, 1,286,068 bushels of corn, and 298,790 barrels of meal; in
1846-47 16,326,050 bushels of corn, and 948,060 barrels of meal; in
1850-51, 3,426,811 bushels of corn, and 203,622 barrels of meal. More
than eleven millions of bushels of Indian corn were consumed in 1850,
in the manufacture of spirituous liquors.

According to the census of 1840, the corn crop of the United States
was 377,531,875 bushels; in 1850, 592,326,612 bushels.

The increase in the production of corn in Ohio has been (in ten years)
66 per cent. I have also before me the auditor's returns for the crop
of 1850, as taken by assessors, and the number of acres planted. The
auditor's returns are:--

Seventy-three counties 55,079,374
Darke county 524,484
Twelve counties, average 8,400,000
----------
Total 64,003,858

This is an advance of 15 per cent. on the crop of 1840, and it is
known that the crop of 1850 was better than that of 1849. The number
of acres planted, and the average production was:--

Acres planted 1,810,947
Bushels produced 64,003,858
Average per acre 35-3/8 bush.

Considering how large a portion of hill land is planted, and how many
fields are ill cultivated, the average is high. Many persons have
believed that taking all years and all lands into view, the average of
corn lands was not more than thirty bushels. But the immense fertility
of _bottom_ lands on the rivers and creeks of Ohio make up for bad
cultivation and inferior soil. We may see something of the differences
in the production of corn, by taking the averages of different
counties, thus:--

Acres. Crop. Average.
Butler 62,031 2,646,353 421/2
Warren 42,322 1,757,409 42
Pickaway 65,860 2,627,727 40
Ross 69,520 2,918,958
