of pecuniary success in one business than in others, more persons would engage their capital in the business, or would bring up their sons to it; which in fact always happens when a business, like that of an engineer at present, or like any newly established and prosperous manufacture, is seen to be a growing and thriving one. If, on the contrary, a business is not considered thriving; if the chances of profit in it are thought to be inferior to those in other employments; capital gradually leaves it, or at least new capital is not attracted to it; and by this change in the distribution of capital between the less profitable and the more profitable employments, a sort of balance is restored. The expectations of profit, therefore, in different employments, cannot long continue very different: they tend to a common average, though they are generally oscillating from one side to the other side of the medium.
This equalizing process, commonly described as the transfer of capital from one employment to another, is not necessarily the onerous, slow, and almost impracticable operation which it is very often represented to be. In the first place, it does not always imply the actual removal of capital already embarked in an employment. In a rapidly progressive state of capital, the adjustment often takes place by means of the new accumulations of each year, which direct themselves in preference towards the more thriving trades. Even when a real transfer of capital is necessary, it is by no means implied that any of those who are engaged in the unprofitable employment, relinquish business and break up their establishments. The numerous and multifarious channels of credit, through which, in commercial nations, unemployed capital diffuses itself over the field of employment, flowing over in greater abundance to the lower levels, are the means by which the equalization is accomplished. The process consists in a limitation by one class of dealers or producers, and an extension by the other, of that portion of their business which is carried on with borrowed capital. There is
