"I know not when I have been more humiliated, as a North Carolina farmer, than when, a few weeks ago, at a railroad depot at the very doors of our State capital, I saw wagons drawn by Kentucky mules, loading with Northern hay, for the supply not only of the town, but to be taken to the country. Such a sight at the capital of a State whose population is almost exclusively devoted to agriculture, is a most humiliating exhibition. Let us cease to use every thing, as far as it is practicable, that is not the product of our own soil and workshops--not an axe, or a broom, or bucket, from Connecticut. By every consideration of self-preservation, we are called to make better efforts to expel the Northern grocer from the State with his butter, and the Ohio and Kentucky horse, mule and hog driver, from our county at least. It is a reproach on us as farmers, and no little deduction from our wealth, that we suffer the population of our towns and villages to supply themselves with butter from another Orange County in New-York." We have promised to prove that the hay crop of the free states is worth considerably more than all the cotton, tobacco, rice, hay and hemp produced in the fifteen slave States. The compilers of the last census, as we learn from Prof. De Bow, the able and courteous superintendent, in making up the hay-tables, allowed two thousand two hundred and forty pounds to the ton. The price per ton at which we should estimate its value has puzzled us to some extent. Dealers in the article in Baltimore think it will average twenty-five dollars, in their market. Four or five months ago they sold it at thirty dollars per ton. At the very time we write, though there is less activity in the article than usual, we learn, from an examination of sundry prices-current and commercial journals, that hay is selling in Savannah at $33 per ton; in Mobile and New Orleans at $26; in Charleston at $25; in Louisville at $24; and in Cincinnati at $23. The average of these prices is _twenty-six dollars sixteen and two-third cents_; and we suppose it would be fair to employ the figures which would indicate this amount, the net value of a single ton, in calculating the total market value of the entire crop. Were we to do this--and, with the foregoing facts in view, we submit to intelligent men whether we would not be justifiable in doing it,--the hay crop of the free states, 12,690,982 tons, in 1850, would amount in valuation to the enormous sum of $331,081,695--more than four times the value of all the cotton produced in the United States during the same period!
