Let us suppose thirty-three head of cattle to have been fed on hay, and that each consumed two stone per day; estimating the produce of an acre of hay at one hundred and sixty stone; at this rate it would have required eighty-two acres to have fed them for 200 days, admitting the after-grass to have been adequate to the support of thiity-five head of Highland heifers, and sixty sheep for the like space of time. If I am correct in this calculation, there will be found a clear gain to the public of sixty acres of land in the feeding of this trifling stock.
A moderate acre of green food is supposed to produce 15 tons, or 24OO stone; but with the drill husbandry, I conceive the weight will be considerably greater.
I have not thought proper to make any alteration in the preceding statement of the supposed weight of green crop, but suffered it to remain as an example of the danger of arguing from any thing but actual experience. Fortunately for the position I maintained, the green crops under my own inspection (obtained with coal ashes) greatly exceed the data upon which I calculated. Subsequent information obtained of the weight of turnip crops in Durham and Northumberland, offers a further confirmation of the value. of green crops. I am much indebted to my ingenious and intelligent friend, Mr. G. Taylor, of St. Helen's, Auckland, for the following valuable communication of an experiment made by the Durham Society for Agricultural Experiments, and for the permission granted me by the Society to make use of them.."

REMARKS—The soil was a rich sandy loam, manure the same to all. The superiority of weight in the broad cast yellow bullock and Swedish, is supposed to havfc arisen.from the smallness of top in these kinds, which was allowed for in heeing the broad cast, but could not be equally allowed for in the drilled, because the latter are "set out," or hoed, for the first time, at an earlier period, when the difference of top is not obvious, nor had this difference been adverted to in regulating the stitches, In the Norfolk white, to which the labourers had been accustomed, the drilled appear with their usual superiority.

After the rate of four stone per day, an acre would supply food for one beast for 600 days. At the rate of two stone of hay per day, it would require seven acres and a half; but say seven, allowing the half acre for the straw likewise given. We ought, in striking the balance in favour of green crops, to take into the account its impoverishment of the ground by hav, and the improvement by green crops. The drill husbandry, under judicious management, is the best mode of improvement, and might be alternately practised with green crops till the end of time.
