But as the full significance of this "machine-made" age is grasped it will be seen that it has set free the human laborer, if only he will qualify himself to use the power at his hand.

The house will become the first lesson in the use of mechanical appliances, in control of the harnessed forces of nature, and of that spirit of cooperation which alone can bring the benefits of modern science to the doors of all.

One family cannot as a rule put up in a city or in the suburbs--and half the world lives in cities--its own idea of a house without undue expenditure; but ten families may combine and secure a building which fairly suits them all.

I say fairly, because all cooperation means some sacrifice of whim or special liking.

The well-balanced individual will, however, choose the plan yielding on the whole the greater efficiency, thus following a law of natural selection which, so far, the human race has ignored--a neglect which has been carrying him toward destruction as surely as there is law in nature.
