is, the perpetual overflow of capital into colonies or foreign countries, to seek higher profits than can he obtained at home. I believe this to have been for many years one of the principal causes by which the decline of profits in England has been arrested. It has a twofold operation. In the first place, it does what a fire, or an inundation, or a commercial crisis would have done: it carries off a part of the increase of capital from which the reduction of profits proceeds. Secondly, the capital so carried off is not lost, but is chiefly employed either in founding colonies, which become large exporters of cheap agricultural produce, or in extending and perhaps improving the agriculture of older communities. It is to the emigration of English capital, that we have chiefly to look for keeping up a supply of cheap food and cheap materials of clothing, proportional to the increase of our population; thus enabling an increasing capital to find employment in the country, without reduction of profit, in producing manufactured articles with which to pay for this supply of raw produce. Thus, the exportation of capital is an agent of great efficacy in extending the field of employment for that which remains: and it may be said truly that, up to a certain point, the more capital we send away, the more we shall possess and be able to retain at home.
In countries which are further advanced in industry and population, and have therefore a lower rate of profit, than others, there is always, long before the actual minimum is reached, a practical minimum, viz. when profits have fallen so much below what they are elsewhere, that, were they to fall lower, all further accumulations would go abroad. In the present state of the industry of the world, when there is occasion, in any rich and improving country, to take the minimum of profits at all into consideration for practical purposes, it is only this practical minimum that needs be considered. As long as there are old countries where capital increases very rapidly, and new countries where profit is still high, profits in the old countries will not sink to the rate which
