Mr. Astor married a daughter of General Armstrong, the Secretary of War in Mr. Madison's cabinet. He has two sons, who are themselves fathers of families. They are John Jacob and William B. Astor, Jr. He has also several daughters, all married. The sons reside on Fifth avenue. They are in active business for themselves. John Jacob, the elder, is a large-framed, heavy-boned man, and resembles his father. William B. Astor, Jr., is a small, slim man, and resembles his mother. They are much more sociable than their father, inheriting much of the genial vivacity of their grandfather, who was very fond of the pleasures of society. They are shrewd, energetic business men, and it is said are very wealthy, independent of their father. Mr. John Jacob Astor entered the United States Army during the civil war, and saw considerable active service on the staff of General McClellan. XXIII. FASHIONABLE SHOPPING. The fashionable retail stores of New York lie chiefly along Broadway, between the St. Nicholas Hotel and Thirty-fourth street. A few are to be found in the cross streets leading from the great thoroughfare, and some are in the Sixth avenue, but Broadway almost monopolizes the fashionable retail trade of the city. All the large stores are conducted on the same general plan, the main object of which is to secure the greatest convenience and comfort for the purchaser, and the greatest dispatch and promptness on the part of the employes. The leading stores of the city have an established reputation with the citizens. They furnish a better class of goods than can be found elsewhere, and are the most reasonable in their prices. Furthermore, the purchaser may rely upon the assurances of the salesman concerning the goods. The salesmen in such houses are not allowed to represent anything as better than it really is. This certainty is worth a great deal to the purchaser, who is often incapable of judging intelligently of his purchase. The writer can assert, from actual experience, that for the same amount of money one can buy at the first-class stores a better article than is offered in the so-called "cheap stores."
