The second misgiving, which many calm observers more and more feel as to our largest joint stock banks, fastens itself on their government. Is that government sufficient to lend well and keep safe so many millions? They are governed, as every one knows, by a board of directors, assisted by a general manager, and there are in London unrivalled materials for composing good boards of directors. There are very many men of good means, of great sagacity and great experience in business, who are obliged to be in the City every day, and to remain there during the day, but who have very much time on their hands. A merchant employing solely or principally his own capital has often a great deal of leisure. He is obliged to be on the market, and to hear what is doing. Every day he has some business to transact, but his transactions can be but few. His capital can bear only a limited number of purchases; if he bought as much as would fill his time from day to day he would soon be ruined, for he could not pay for it. Accordingly, many excellent men of business are quite ready to become members of boards of directors, and to attend to the business of companies, a good deal for the employment's sake. To have an interesting occupation which brings dignity and power with it pleases them very much. As the aggregation of commerce in great cities grows, the number of such men augments. A council of grave, careful, and experienced men can, without difficulty, be collected for a great bank in London, such as never could have been collected before, and such as cannot now be collected elsewhere.
