There are certain other buildings designed in the style of a country almost as tropical as Egypt, and as light and airy as that is sombre and gloomy, but which seem quite as appropriate for their different purposes: they are the Casino Theatre and the Synagogue at Fifth Avenue and Forty-third Street,—each an excellent example of Saracenic architecture,—the former of brick and terra cotta, and the latter of vari-colored sandstones. Another synagogue, by Brunner & Tryon, further up the avenue and facing Central Park, has a decided Byzantine flavor,—the large arch accentuating the entrance, carrying a small arcade, and being surmounted by the traceried dome. The largest and most expensively elaborate hotel in America is the Waldorf-Astoria; and although certain features of the exterior may not be justified by interior arrangements, it has certainly been planned with a view to great comfort and luxury. While New York has the largest and most expensive private residences,— the chief of these is that of Cornelius Vanderbilt,—Philadelphia has the greatest number of small houses owned by their occupants; and of late years, there are a greater number of attractive homes in St. Louis than anywhere else in this country. Very many of them have been designed by Eames & Young, or by Shepley, Rutan & Coolidge; and with much open space about them, they have an air of elegance and hospitality that is lacking to the homes in most other cities. New York, from its position as the commercial and financial centre of the country, in spite of its situation on a long, narrow island, may be accepted as the typical city. What is done here architecturally is done (only to a different degree) elsewhere, and its growth horizontally in the northern portion of the city has kept pace with its perpendicular growth in the more congested business portion. This general expansion has altogether changed the character of many streets, the residences becoming apartment houses, and the shops becoming office buildings from ten to twenty stories,—or even more,—the masses becoming larger and the detail proportionately less prominent.
