Professor Beck examined thirty-three different samples from various parts of the United States and Europe, and he gives the preference to the Kobanga variety from the south of Russia.  There would probably be a prejudice against it in this country, from the natural yellowish hue of its flour and bread.

The value of the vegetable food, grain, potatoes, rice and apples exported from the United States within the past few years is thus set down:—­

Dollars.
1847           57,970,356
1848           25,185,647
1849           25,642,362
1850           15,822,273

To this has to be added nine or ten million dollars more for tobacco, 72 million dollars for cotton, and 180,000 dollars for hops and other minor agricultural staples—­making the value of the raw vegetable exports about 98 million dollars.  There is further the value of the products of the forest, timber, ashes and bark, tar, &c., which are equal to nearly seven millions more, as shown by the following figures:—­

Dollars.
1847          5,248,928
1848          6,415,297
1849          5,261,766
1850          6,590,037

It appears from an official document of the American Treasury Department, that the average value of the breadstuffs and provisions annually exported from the United States from 1821 to 1836 inclusive, was 12,792,000 dolls.; in 1837 and 1838, about 9,600,000 dolls.; from 1839 to 1846, 16,176,000 dolls.; and for the last seven years as follows:—­

Dollars.
1846          27,701,121
1847          68,701,921
1848          37,472,751
1849          38,155,507
1850          26,051,373
1851          21,948,651
1852          25,857,027

Out of the wheat crop in the United States in 1846 of 110 million bushels raised, 10 millions were used for seed, starch, &c.; 72 consumed for food, and 28 million exported.  The 460 million bushels of Indian corn raised, were thus disposed of; exported to foreign countries 22 million bushels; sold to and consumed by non-producers, 100 million; consumed on the farms and plantations of the producers for human and animal food, seed, &c., 338 million bushels.

The United States now produce about 120 million bushels of wheat, and nearly 600 million bushels of corn.  Their surplus of wheat, for export, may be taken at 20 million bushels, and of Indian corn an almost unlimited quantity.  They export about one and a quarter million barrels of flour, and about one million of bushels of wheat to other markets besides those of Great Britain or her North American colonies, viz., to Europe, Asia, Africa, the West Indies and South America, California and Australia, manufactured flour being the article required for these latter markets.  Nearly four million bushels of Indian corn, and 300,000 barrels of corn meal, are exported from the United States to the West Indies and other foreign markets.
