The distinguishing characteristic of the trustee savings bank is _mutuality_. _All_ the earnings of the bank, less reasonable administrative expenses and the apportionment to surplus or guaranty fund, are divided among the depositors in the form of interest. One or two features of the mutual bank may be mentioned. First, the investments of such institutions are usually carefully restricted, looking primarily to the element of safety; and as long as the trustees keep their funds so invested they cannot be held, either in law or morals, responsible for losses. Second, the predominancy of the mortgage loan. The nature of the deposits being more or less permanent, investments of a permanent character may be made without fear of a sudden demand for their return on the part of depositors; and to safeguard the banks from such unexpected calls, quite generally trustee banks are permitted by law to require notice, the usual time being either sixty or ninety days. The third distinguishing feature is the self-perpetuation of the board of managers. No amount of money can _buy_ a man's way into a mutual savings bank. He cannot, as in stock concerns, buy enough stock to _vote himself_ into office--he can only gain office as the other men advocate his cause. And, on the contrary, he cannot be voted _out_ of office. Only an act, such as bankruptcy (which voids his office), can affect him, and, like a Supreme Court judge, he is appointed during good behavior. The greatest weakness of the trustee bank is this: Lacking the "essential element" that prompts men to undertake such ventures (profit), it does not appeal to the average man of means unless he is sentimentally inclined; and not being indispensable to trade and commerce, like a bank of discount, it does not come to be a commercial necessity. Even in a great State like New York we find twenty-eight counties with no savings banks. And in many of these counties there are large and thriving towns and cities. Thus the city of Jamestown, with over 30,000 population, has no savings banks; while Elmira, with over 35,000 population, has but one, and that with but half a million assets. From the viewpoint of intensive results, as tested by the volume of patronage accorded these institutions, a perusal of the statistics will demonstrate that in some places the trustee bank has had a remarkable record. For instance, in Maine, a sparsely-settled State, and largely of a rural nature, we find one savings account to every 3 of the population. More remarkable is Vermont, the "Green Mountain State," where natural conditions would seem to be much more hostile to such development, we find 30 per cent. of the population having savings bank accounts. New Hampshire has an account for every 2-1/2 of the population, while Massachusetts heads the list, with seventy-five out of every hundred. New York has one to every three.
