The Seventh Census (1850) returned the Hay-crop of the preceding year at 13,838,642 tuns, which the Eighth Census increased to 19,129,128 tuns as the product of 1859. Confident that most farmers underestimate their Hay-crops, and that hundreds of thousands who do not consider themselves farmers, but who own or rent little homesteads of two to ten acres each, keeping thereon a cow or two and often a horse, fail to make returns of the two to five tuns of Hay they annually produce, considering them too trivial, I estimate the actual Hay-crop of all our States and Territories for the current year at 40,000,000 tuns, or about a tun to each inhabitant, although I do not expect the new Census to place it much, if any, above 25,000,000 tuns. The estimated average value of this crop is $10 (gold) per tun, making its aggregate value, at my estimate of its amount, $400,000,000--and the quantity is constantly and rapidly increasing. That quantity should be larger from the area devoted to meadows, and the quality a great deal better. I estimate that 30,000,000 acres are annually mowed to obtain these 40,000,000 tuns of Hay, giving an average yield of 1-1/3 tuns per acre, while the average should certainly not fall below two tuns per acre. My upland has a gravelly, rocky soil, not natural to grass, and had been pastured to death for at least a century before I bought it; yet it has yielded me an average of not less than 2-1/2 tuns to the acre for the last sixteen years, and will not yield less while I am allowed to farm it. My lowland (bog when I bought it) is bound henceforth to yield more; but, while imperfectly or not at all drained, it was of course a poor reliance--yielding bounteously in spots, in others, little or nothing. In nothing else is shiftless, slovenly farming so apt to betray itself as in the culture of Grass and the management of grass lands. Pastures overgrown with bushes and chequered by quaking, miry bogs; meadows foul with every weed, from white daisy up to the rankest brakes, with hill-sides that may once have been productive, but from which crop after crop has been taken and nothing returned to them, until their yield has shrunk to half or three-fourths of a tun of poor hay, these are the average indications of a farm nearly run out by the poorest sort of farming. Such farms were common in the New England of my boyhood; I trust they are less so to-day; yet I seldom travel ten miles in any region north or east of the Delaware without seeing one or more of them.
