The question is often asked why trusts have not been formed before, and what the causes are which have started them up so rapidly in such varied lines of industry. There is certainly room for much honest difference of opinion in reference to these causes; but one cause concerning whose influence there can be no dispute is the culmination of the change from the ancient system of manufacturing to the modern. Let us briefly trace the manner in which this branch of civilization has grown: In the most primitive state of existence, each man procures and prepares for himself the few things which he requires. With the first increase in intelligence those of most skill in making weapons and preparing skins make more than they require for themselves, which they exchange with others for the products of the chase. The next step is to teach to others the special skill required, and to employ them to aid the chief workman. Conditions analogous to these existed down to the end of the last century. The great bulk of all manufacturing was done in small shops, each employing only a few workmen; and the manufacturer or master workman labored at the side of his journeymen and apprentices. The products of these little workshops were sold in the country immediately adjacent. Of course the number of these scattered shops was so great that the possibility of uniting all the manufacturers in any one trade into a single organization to prevent competition among them, was beyond the thoughts of the most visionary.
