The New York Tribune is pretty good authority. These figures are undoubtedly from the calculations and from the pen of Mr. Grosvenor, of the editorial staff of that able journal, formerly editor and proprietor of the "Public," whose estimates of prices have, in my judgment, been more correctly made than those of any other statistician in the world. The article is as follows: Quotations of about two hundred articles are compared since 1860, and the amount of money is ascertained which would purchase, at different dates, of these various articles, quantities corresponding as closely as possible to their ascertained consumption in 1880, the date of the last census. Among the articles compared are wheat, corn, oats, rye, barley, beans and pease, mess pork, bacon, ham, live hogs, lard, fresh beef, tallow, live sheep, poultry, butter, cheese, eggs, milk, hay, potatoes, turnips, cabbage, onions, apples, raisins, sugar, brown and crushed; molasses, coffee, tea, tobacco, whisky, malt and hops, mackerel, codfish, salt, rice, nutmegs, cloves, pepper, cotton, print-cloths and standard sheeting, wool of different qualities, blankets, carpets, flannels, leather, boots, shoes, hides, silk, India rubber, iron (pig and bar), nails, steel rails, coal, oil (crude and refined), tin and tin plates, copper, lead, hemp, lumber, spruce and pine, oak, ash, walnut, and white wood, lath, brick, lime, turpentine, linseed oil, soap, glass, paper, white lead, and twelve other kinds of paints, fertilizers, and over fifty kinds of drugs and chemicals. _Cost of products at different dates._
