Rh require, and employ little labour besides that of their own family; in other cases, by large numbers working together in one building, with expensive and complex machinery owned by rich manufacturers. The same difference exists in the operations of trade. The wholesale operations indeed are everywhere carried on by large capitals, where such exist; but the retail dealings, which collectively occupy a very great amount of capital, are sometimes conducted in small shops, chiefly by the personal exertions of the dealers themselves, with their families, and perhaps an apprentice or two; and sometimes in large establishments, of which the funds are supplied by a wealthy individual or association, and the agency is that of numerous salaried shopmen or shopwomen. Besides these differences in the economical phenomena presented by different parts of what is usually called the civilized world, all those earlier states which we previously passed in review, have continued in some part or other of the world, down to our own time. Hunting communities still exist in America, nomadic in Arabia and the steppes of Northern Asia; Oriental society is in essentials what it has always been; the great empire of Russia is even now, in many respects, the scarcely modified image of feudal Europe. Every one of the great types of human society, down to that of the Esquimaux or Patagonians, is still extant.

These remarkable differences in the state of different portions of the human race, with regard to the production and distribution of wealth, must, like all other phenomena, depend on causes. And it is not a sufficient explanation to ascribe them exclusively to the degrees of knowledge possessed at different times and places, of the laws of nature and the physical arts of life. Many other causes co-operate; and that very progress and unequal distribution of physical knowledge are partly the effects, as well as partly the causes, of the state of the production and distribution of wealth.

In so far as the economical condition of nations turns upon the state of physical knowledge, it is a subject for the
