Thousands of carcasses hung on hooks are scarcely pleasing to the aesthetic sense, but the red-brick exterior of the London Central Meat Market, designed by Sir Horace Jones in the Renaissance style, with a tower at each of the four corners, is admirably effective. The internal arrangements of the Market may be described as ideal. It is light, airy, and commodious, being 630 feet long, 245 feet broad, and 30 feet high, with a glass and iron roof. Altogether, three-and-a-half acres are occupied by the Market, into which large quantities of the meat are conveyed by means of lifts from a depot below connected with the underground railways. Smithfield is worth visiting, if only to see the characteristic types of humanity that are common here; but it is well not to choose a hot summer's day for the purpose.
