According to Playfair, a horse not working can subsist and remain in fair condition on a daily allowance of 12 lbs. of hay and 5 lbs. of oats. According to the same authority, a working horse should receive 14 lbs. of hay, 12 lbs. of oats, and 2 lbs. of beans. Beans are a very concentrated food, rich in flesh-formers, and are, therefore, well adapted for sustaining hard-working horses. They are rather _binding_; but this property is easily neutralised by combining the beans with some laxative food. Turnips, carrots, furze, and various other foods are given to the horse, often in large quantities. The following are some among the many dietaries on which this animal is kept:-- Professor Low's formula is, 30 to 35 lbs. of a mixture of equal parts of chopped straw, chopped hay, bruised grain, and steamed potatoes. The daily rations of horses of the London Omnibus Company, are 16 lbs. of bruised oats, 7-1/2 lbs. of cut hay, and 2-1/2 lbs. of chopped straw. Stage coach-horses in the United States receive daily about 19 lbs. of Indian meal and 13 lbs. of cut hay. Mr. Robertson, of Clandeboye, near Belfast, gives the following information on the subject of horse-keeping:-- The year we divide into three periods--October, November to May inclusive, June to September inclusive. During the first period, the horses get about 18 lb. of chaff and 12 lb. of crushed oats and beans; "10-1/2 oats and 1-1/2 beans" per head per day. During the second period they get about 15 lb. of hay chaff, 12 lb. of crushed oats and beans, and about 3 gallons of boiled turnips per head per day. During the third period they were turned out to graze during the night. In the day time, whilst in the stable, each animal is allowed about 50 lb. of cut clover, and about 12 lb. of crushed oats and beans per day. The feeding is all under the charge of one person. He uses his own discretion in feeding the animals, though he is not allowed to exceed the quantities named. The horses to which I allude are the same on which the experiments commenced two years ago--six cart horses, one cart pony, and one riding horse. From Sept. 1, 1865, to and including August 31, 1866, the cost of maintaining these horses in good working condition; keeping the carts, harness, &c., in repair; shoeing, c., was as follows:--
