The preparation of hay-tea is very simple. Nice hay is run through a cutter, and taking an ordinary two-gallon pailful, boiling water is poured upon it; it is then covered and allowed to steep for twelve hours. This makes a most excellent food, and calves thrive upon it. The most stylish and vigorous calf I ever saw, was raised upon hay-tea, with bran and cotton-seed meal as here described. I enter thus fully into the best manner of raising a calf without its mother, for the especial benefit of my southern readers, where the thriftless habit of allowing the calf to suck its dam, oftentimes until a year old, so generally prevails. In this instance the little heifer got along nicely until two months old, when an aggravated attack of scours set in, but by timely doses of laudanum in a mess of warm gruel, poured down her throat twice a day, for three days, a cure was effected. In ordinary cases of scours, a change to dry food will correct it, but it is well to watch and not to permit the disease to become seated. A few years ago, a very valuable young Jersey heifer, received from the vicinity of Philadelphia, was taken in this way, while undergoing the usual course of acclimation incident to northern cattle brought south, and the simpler treatment proving of no effect, I gave injections twice a day of rice-water and laudanum, besides drenching her with corn-gruel and laudanum. This was kept up for ten days; we carried her safely through, and her present value amply compensates for the time and trouble expended. FOOD OF THE COW.
