Banks created and governed under the provisions of the "National Bank Act." They are private corporations organized under a general law of congress, by individ- ual stockholders, with their own capital, for private gain, and managed by officers, agents, and employes of their own selection. They constitute no part of any branch of the government of the United States, and whatever public benefit they contribute to the country in return for grants and priv- ileges conferred upon them by statute, is of a general nature arising from their busi- ness relations to the people through individ- ual citizens, and not as direct representa- tives of the state as a body politic in exer- cising its legal and constitutional func- tions; 12 Ct. Cl. 281; but they are instru- ments designed to aid the government in an important branch of the public service; 91 U. S. 29. See 164 U. S. 347. Congress in the exercise of an undisputed constitu- tional power to provide a currency for the whole country, may constitutionally secure the benefit of it to the people by appropri- ate legislation, and to that end may restrain the circulation of any notes not issued un- der its authority; 8 Wall. 548. Any number of persons, not less than five, may organize a national bank. They must sign, acknowledge before a court of record or notary public, and transmit to the comptroller of the currency, an or- ganization certificate, containing the name of the bank, its place of business, the amount of capital stock and the number of shares into which it is to be divided, the names and residences of the share- holders, and the number of shares held by them, and that the applicants desire to avail themselves of the act of congress. The comptroller decides whether the bank is lawfully entitled to begin business; see 19 Mich. 196; if he so finds, his certificate of this fact must be published in a newspaper of the place where the bank is to do business for sixty days. One hundred thousand dollars is the minimum capital allowed, except in places not exceeding 6,000 inhabitants, when, by consent of the comptroller, the capital may be $50,000; where the population ex- ceeds 50,000 the capital must be at least $200,000. The term capital does not refer to borrowed money, but to the property or moneys of the bank permanently invested in its business; 21 Wall. 284. The capital stock is divided into shares of $100 each, which are personal property. At least fifty per cent. thereof must be paid in be- fore organization, and the rest in monthly instalments of ten per cent. each. The stock of stockholders not paying these instalments may be sold, on notice; stock- holders are individually responsible, in addition to what they have invested in their shares, for all contracts, debts, and engage- ments of the bank, to the extent of their stock at its par value. This liability is several and not joint; 8 Wall. 505. The estate of a deceased owner of bank stock is liable to an assessment levied against his executor in consequence of the failure of the bank after his death; 60 Fed. Rep. 326; 121 U. S. 27. Upon its organization a national bank has the usual corporate powers, also the right of succession for twenty years, and the power to exercise, by its board of directors or duly authorized officers or agents, subject to law, all such incidental powers as shall be necessary to carry on the business of banking; by discounting and negotiating promissory notes, etc.; by receiving deposits, by buying and sell- ing exchange, coin, and bullion; by loan- ing money on personal security; and by obtaining, issuing, and circulating notes according to the provisions of title 62 of the Revised Statutes. They have not the same rights in all the states. For all practical purposes they exercise their functions only within the limits of the state in which they are located and they have no authority to carry on business outside those limits; 2 McCrary 95:6 Hun 71. The powers of national banks are to be measured by the act creating them; 18 Wall. 589; 72 Pa. 456; 62 Mo. 329; 139 U. S. 67; the words of the act above quoted, "by discounting and negotiating promissory notes, etc.," are not to be read as limiting the mode of exercising the "incidental powers" necessary to carry on the business of banking, but as descriptive of the kind of business which is authorized; 22 Ohio St. 516. A national bank may buy negotiable notes and bills of exchange; 33 Minn. 40; 23 S. C. 339; 20 Kan. 440. This power, it has been held, simply implies an authority to realize upon such commercial paper as the bank may receive in the law- ful conduct of its business, by negotiating, selling, and transferring it by means of a re-discount obtained or otherwise. It gives no implied authority to speculate or traffic in paper of this character or in financial securities of any description; 24 Minn. 140; 52 Md. 78. In the last case, by a divided court, the opinion was qualified by the remark that a national bank might inves
