“ Little more than one-half the total area of the county is under cultivation; and the grain crops, greatly decreasing, are insignificant. The soil in the north and north-west is heavy, poor clay; but the rich alluvial soil of the Thames Valley is specially suitable for market gardens. On the outskirts of London much land now built over was formerly devoted to market gardening. The number of livestock decreases; in fact, agriculture as a whole has slowly to give place to extension of building. Industries are extensive and varied. ”
