It is considered that production, with the present labor force, is at its maximum, and if a yield of coal commensurate with the world's need is to be attained, at least seventy percent more men must be supplied.

We have extended the range of applied science until we daily use infinite forces, and those forces must, apparently, disrupt our society, unless we can raise the laws and institutions which hold society together to an energy and efficiency commensurate to them.

Although the very growth and existence of the larger industrial units implies, as we saw, a laying aside of smaller conflicts, we cannot assume that the forces at present working directly for the pacification of capital and labour, and for their ultimate fusion, are at all commensurate in importance with the concentrative forces operating in the two industrial elements respectively.
