5. In the department of the Interior there is a board whose duty it is to superintend the work of taking the census. It prepares, prints, and sends to every Marshal the blanks to be used by him and his assistants; and when they have made returns of their work, the board arranges them preparatory to laying them before Congress. After this they are published, and make a valuable work of reference; for they contain a vast amount of statistical information—such as the number of acres of land under cultivation, the number of bushels of grain of every kind produced in the year; the number of horses, cattle, sheep, swine, &c., raised; the number of manufacturing establishments, and the amount of their productions; the number of churches, schools, colleges, &c.; the number of deaf, blind, idiotic, and insane persons; together with much other matter, quite too voluminous for insertion here. 6. All this is done by order of Congress, and of course paid for from the United States Treasury. Elsewhere in this book (see index) we give a tabular statement of the population of each State and Territory, at each time the census has been taken by the United States. It shows the increase at each decade from 1790, the first time it was taken, to 1870—the last at this date. This table also shows the increase in the number of States, from the original 13 to the present 37, besides the Territories, which alone are larger than the original 13 States, and nearly as numerous. CHAPTER XXXVIII. THE DEPARTMENT OF AGRICULTURE. Was established by an act of Congress, May, 1862. It is not, like the other Departments of the Executive Branch of the government, superintended by a Secretary with a seat in the President’s Cabinet. Its Head is called The Commissioner of Agriculture, and he is appointed by the President, by and with the advice and consent of the Senate, like other civil officers. The creation of this office is a recognition of the extreme importance of this industry to the prosperity and welfare of the nation. Our country is eminently an agricultural one; and the interests confided to this department are those of a class of the people more numerous than any other, and on the success of whose labors depends the well being of all. In proportion as this industry attains a high state of development, and is generally prosperous, do the professional, mercantile, and manufacturing classes increase in wealth. It is the foundation on which they build. The great fertility of our country, and the breadth of area adapted to all the most useful products of the world, and the need of instruction, suggestion, and aid in properly adapting agricultural products to the soil and climate, by the large number of settlers in regions with whose peculiarities they are but partially familiar, give a special interest and value to this new Department.
