The benefit of such an institution is two fold. In the first place there are many persons who have small sums of money which they desire to be earning something in some safe place. The amount is too small to be loaned to advantage. Such persons are not likely to know how, even if the sums at their disposal were sufficient, to find the best investment, or to determine concerning the security offered. But put into the hands of men who make this their business, under rules devised by the best financial talent of the community, and who can combine these small sums and invest them to the best advantage, it is made both safe and profitable for the small capitalists. In the second place there are many persons who wish to unite their labor and skill with capital in some productive enterprise, and having no capital of their own, desire to borrow. They do not know the persons who have money to loan. The savings bank affords them an opportunity and gives them an advantage which they would not otherwise have. It is a benefit first to those who have some surplus, but are unable to loan it to advantage; secondly to those who are in want of capital, but do not know where to find it. A _bank of deposit_ grows out of the necessities of commerce in a community where much business is transacted. All persons engaged in trade will find from time to time large or smaller accumulations of money in their hands which it is not safe without considerable expense, to keep by them. Hence the custom of depositing these for safe keeping in the bank. Usually no interest is paid as the money may be withdrawn any time at the will of the depositor. It was early found that only a small proportion of these deposits were likely to be withdrawn at any one time; hence a considerable proportion of them could be loaned on short time, and thus the bank would in this way receive compensation for its care, without expense to the depositors. In this way, too, the capital of the community could be kept more fully employed.
