It is also gratifying to note the evidences of improvement in some of the most important agri- cultural operations, proving that our farmers are fully in sympathy with the progressive spirit of the age, and not behind their fellow citizens engaged in other industrial occupations. . The increasing annual products of agriculture in our highly-favored country, and the hay and grain crops in particular, furnish striking illustrations of the close interdependence and connection of all branches of the national industry. Without the improvements in ploughs and other implements of tillage which have been multiplied to an incredible extent, and are now apparently to culminate in the steam plough, the vast wheat and corn crops of those fertile plains could not probably be raised. But were it possible to produce wheat upon the scale that it is now raised, much of the profit and not a little of the produce would be lost were the farmer compelled to wait upon the slow process of the sickle, the cradle, and the hand-rake for securing it when ripe. The reaping machine, the harvester, and the machines for threshing, winnowing, and cleaning his wheat for the market have become quite indispensable to every grower.(8) Manufacturing, if anything was changing even more rapidly than was agriculture. The returns of MANUFACTURES exhibit a most grat- ifying increase, and present at the same time an imposing view of the magnitude to which this branch of the national industry has attained within the last decennium. The total value of domestic manufactures, (including fisheries and the products of the mines,) according to the Census of 1850, was $1,019,106,616. The product of the same branches for the year ending June 1, 1860, as already ascertained in part and carefully estimated for the remainder, will reach an aggregate value of nineteen hundred millions of dollars ($1,900,000,000). This result exhibits an increase of more than eighty-six (86) percentum in ten years!(9) Ibid., pp. 81-82. 9Ibid., p. 59.
