There are two cities in Bombay, the native city and the foreign city. The foreign city spreads out over a large area, and, although the population is only a small per cent of that of the native city, it occupies a much larger space, which is devoted to groves, gardens, lawns, and other breathing places and pleasure grounds, while, as is the custom in the Orient, the natives are packed away several hundred to the acre in tall houses, which, with over-hanging balconies and tile roofs, line the crooked and narrow streets on both sides.
