CHARTS.-The larger charts are as follows:

1. Showing the corn and wheat production of the country, with the exports, seed used, and home consumption for five years, constituting the first half of the present decade. It is 7 feet 6 inches in height and 4 feet 6 inches wide, with diagrams presenting these details of average production on a scale of three-fourths of a million bushels to the square inch. It is a lucid and striking showing, especially to foreigners unfamiliar with the immensity of our cereal productions and the comparatively small proportion of the whole sent abroad.

The accompanying diagram represents it on a reduced scale. This chart makes the average supply of corn, in excess of export, for each unit of population, almost exactly 24 bushels for this period; the average area in cultivation, 37,699,803 acres; and the yield per acre 26.3 bushels. The statement accompanying the chart represents corn production and distribution as follows:

An importation of corn is a fact scarcely dreamed. A little crosses our northern boundary from the Dominion, averaging 68,864 bushels. The average supply of wheat in excess of export is 5 bushels; area in cultivation (average for five years), 21,386,709; yield per acre, 12.2 bushels. The imports of wheat have averaged 1,502,541 bushels, of which about three-tenths have been exported. The wheat figures are as follows:

2. Showing the proportion of improved lands to the farm-area of eaco State and Territory. This is given in classes as follows:

Under 30 per cent.: North Carolina, South Carolina, Georgia, Louisiana, Texas, Arkansas, Dakota, Colorado, New Mexico, Washington, Wyoming; 30 and under 40 per cent.: Florida, Alabama, Minnesota, Mississippi, Tennessee, West Virginia, Kansas, Nebraska, Idaho; 40 and under 50 per cent.: Maine, Virginia, Kentucky, Missouri, California, Oregon, Nevada; 50 and under 60 per cent.: Rhode Island, Indiana, Michigan, Wisconsin; over 60 per cent.: New Hampshire, Vermont, Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, Ohio, Illinois, Iowa, Utah, Arizona, Montana.

This chart also indicates the extent of several crop-belts, by a delineation of the line of northern limit respectively of sea-island cotton, upland cotton sorghum, and winter-wheat. The line dividing spring wheat from winter is worthy of careful study, as it separates, tortuous as it ap pears, within one or two parts in a hundred, the entire production of fall and spring sown grain. The line runs from near Boston through Southeastern Massachusetts and Connecticut, curves round the Housatonic Hills, strikes the vicinity of Saratoga, and runs in a northwesterly direction to Lake Ontario; thence including all our territory east of Lake Michigan, traverses a small section of Southwestern Indiana, strikes nearly west through the northern line of Missouri, crosses the Missouri at Saint Joseph, and gradually curves southward in Kansas as higher elevation is reached. The general direction from ocean to lakes is northwest, from lakes to the Rocky Mountains west-southwest. The line of northern limit of sorghum, on the contrary, preserves with a degree of uniformity a northwestern course. The difference is, sorghum is a summer crop, and its cultivation follows the summer isother mal line; while winter wheat depends not only on winter and spring climates, but to some extent on the nature of the soil and methods of cultivation.

The sea-island-cotton line skirts the coast from Charleston to Galveston; and the upland line runs from Norfolk southwesterly, curving around the mountain spurs of upper Georgia, cutting the northeastern section of Alabama, and thence sharply northward to include the Tennessee Valley and Western Tennessee, and all but the hill region of Arkansas, and southwestwardly through a corner of the Indian Territory and Texas to the Rio Grande.

Accompanying this chart is an estimate of the extent of cultivation of the principal crops, as follows:
