_Guinea Corn._--The stalks of this grain, if pressed, are said to yield a juice sweeter and of greater body than the sugar cane. _Carrots._--According to some agricultural reports, carrots will yield 600 or even 900 bushels per acre. At the last meeting of _The Columbian Institute_, some valuable specimens of _American plants_, beautifully preserved, were presented by Dr. _Darlington_, a representative in Congress from Pennsylvania; and several fine specimens of _American minerals_, chiefly collected in the valley of the Mississippi, by Mr. _Schoolcraft_, the ingenious author of a work which has lately appeared on the lead mines of Missouri, and natural history, &c. of the western country. _To make fat Lamb._--"To make or fatten lamb for the market, let your ewes be well attended to, and fed upon a patch of rye; upon turnips, or other corresponding food; affording abundant milk. As fast as your lambs fall, and can run well alone, all you have are to be shut up together in a dark pen or stall, of proportionate size to the number of lambs you expect, having a narrow trough, breast high to them, to be daily supplied with Indian corn meal; with the bran in it; and hanging up within their reach one or more wisps or small bundles of fine hay for them to nibble, at. This stall must communicate with, or adjoin, a larger apartment, into which you are to turn ewes twice or thrice a day, to suckle their lambs, and to sleep all night with them.--Before turning the ewes out to pasture, each time, the lambs must be lifted into their small dark pen, or stall, (one six or eight feet square, is sufficiently large for thirty lambs or more,) where they will have no room to skip or play their fat away; here they will nibble so much of the fine hay, and eat so much of the dry Indian corn meal, from want of other employment, as to render themselves voraciously thirsty against the next meal of milk from their dams; which, with the other causes mentioned, makes them grow surprisingly large and fat in a short time. Lambs thus educated, will often promiscuously suck the ewes, without knowing or being attached to their own dams.--Hence a very great advantage: for when all grow large and strong, they become capable of consuming more milk than a single ewe can afford; and more especially those ewes which have two or more lambs each. For upon killing off all the lambs of a ewe, that ewe continues to give suck to the other lambs promiscuously as before, to the great advantage of the surviving lambs, now requiring additional nourishment. This is not the case when lambs run out at large with their dams."
