4. The shoes are removed from the dead horses, and sold, either to be used again, or as old iron. The nails also are collected, and sold. The average produce of the shoes and shoe-nails of a horse is about 2d.

5. The hoofs are sold partly to turners and comb-makers, partly to manufacturers of sal ammonia and Prussian blue, who pay for them about 1s. 5d.

6. The fat is very carefully collected and melted down. In lamps it gives more heat than oil, and is therefore demanded by enamellers and glass toy makers. It is also used for greasing harness, shoe leather, &c.; for soap and for making gas: it is worth about 6d. per lb. A horse on an average yields 8lb. of fat, worth about 4s.; but well fed horses sometimes produce nearly 60lb.

7. The best pieces of the flesh are eaten by the workmen; the rest is employed as food for cats, dogs, pigs, and poultry. It is likewise used as manure, and in the manufacture of Prussian blue. A horse has from 300 to 400lb. of flesh, which sells for from 1l. 8s. to 1l. 17s.

8. The tendons are separated from the muscles: the smaller are sold fresh, to the glue makers in the neighbourhood; the larger are dried, and sent off in greater quantities for the same purpose. A horse yields about 1lb. of dried tendons, worth about 3d.
