HIS work illustrates the development of fine residences
built in this country from the Colonial period to date.

Many fine homes are pictured for the first time — the
great Vanderbilt Mansions and others of that class. The text is
a serious attempt to explain social and economic conditions and
the architectural developments which have produced these
sumptuous buildings.

Nijam of Hyderabad has sanctioned the use of electricity within his dominions.

Bengal, the greatest Presidency in India, has not been idle, having lately installed electric tramways and lighting, with various other improvements, in her capital, known as the "City of Palaces" in history; and even the Northwest Provinces, since the Durbar of 1903 at Delhi, where the benefits of electricity were seen with advantage, have been stirred to seek to improve their districts.

The great problem of the day, however, lies in irrigation and agriculture; and once a suitable scheme is found, in which cost and maintenance are not too great for practical demonstration, then will India rise to the height of her ambition.—ERNEST CHARLES DEEFHOLTZ, Student, American School.
