Crossing Canal street, the widest and most conspicuous we have yet reached, we notice, on the west side, at the corner of Grand street, the beautiful marble building occupied by the _wholesale_ department of Lord & Taylor, rivals of Stewart in the dry-goods trade. The immense brown stone building immediately opposite, is also a wholesale dry-goods house. Between Broome and Spring streets, on the west side, are the marble and brown stone buildings of the St. Nicholas Hotel. Immediately opposite is the Theatre Comique. On the northwest corner of Spring street is the Prescott House. On the southwest corner of Prince street is Ball & Black's palatial jewelry store. Diagonally opposite is the Metropolitan Hotel, in the rear of which is the theatre known as Niblo's Garden. In the block above the Metropolitan is the Olympic Theatre. On the west side, between Bleecker and Amity streets, is the huge Grand Central Hotel, one of the most conspicuous objects on the street. Two blocks above, on the same side, is the New York Hotel, immediately opposite which are Lina Edwin's and the Globe Theatres. On the east side of the street, and covering the entire block bounded by Broadway and Fourth avenue, and Ninth and Tenth streets, is an immense iron structure painted white. This is Stewart's retail store. It is always filled with ladies engaged in "shopping," and the streets around it are blocked with carriages. Throngs of elegantly and plainly dressed buyers pass in and out, and the whole scene is animated and interesting. Just above "Stewart's," on the same side, is Grace Church, attached to which is the parsonage. At the southwest corner of Eleventh street, is the St. Denis Hotel, and on the northwest corner is the magnificent iron building of the "Methodist Book Concern," the street floor of which is occupied by McCreery, one of the great dry-goods dealers of the city. At the northeast corner of Thirteenth street, is Wallack's Theatre. The upper end of the same block is occupied by the Union Square Theatre and a small hotel. [Picture: NEW YORK LIFE INSURANCE COMPANY'S BUILDING.] At Fourteenth street we enter Union Square, once a fashionable place of residence, but now giving way to business houses and hotels. Broadway passes around it in a northwesterly direction. On the west side of Union Square, at the southwest corner of Fifteenth street, is the famous establishment of Tiffany & Co., an iron building, erected at an immense cost, and filled with the largest and finest collection of jewelry, articles of _vertu_, and works of art in America. In the middle of the block above, occupying the ground floor of Decker's Piano Building, is _Brentano's_, the "great literary headquarters" of New York.
