3. The amount of its capital stock (which cannot be less than $50,000), and the number of its shares. 4. The names of its shareholders, and the number of shares held by each. 5. The time when such association shall commence business. 6. A declaration that said certificate is made to enable such persons to avail themselves of the advantages of this act. 3. This certificate must be properly acknowledged before some competent person, and must be sent to the comptroller of the currency in the Treasury Department, to be recorded and kept by him. When this, and all other acts which the law requires, has been done by the association, the comptroller of the currency gives them a certificate under his hand and official seal, to that effect, and that they are authorized to commence business. This constitutes the association a corporation. They have the right to make and use a common seal, and have all the rights, and are liable to all the responsibilities of ordinary legalized corporations; and may exist not to exceed twenty years from the passage of this act. Every shareholder is made personally liable for the debts of the association or bank, to the amount of the par value of his stock. 4. In order to secure the holders of bills issued by these banks, they must deposit with the Treasurer of the United States, United States bonds bearing interest to an amount not less than one-third of the capital stock paid in. These bonds are safely kept by the Treasurer. The comptroller of the currency then issues to the bank an amount of bank notes equal to the amount of bonds thus deposited, less ten per cent. In case the bank should fail to redeem its circulating bills, its bonds are sold, and with the proceeds the comptroller of the currency redeems them, or orders them to be paid at the United States Treasury. The bonds held by the Treasurer as security for the redemption of the bills issued by the association, must be transferred to him in trust; thus giving him entire control of them in case it becomes necessary to sell them in order to redeem the bills of any association which may have failed to pay them on demand. 5. This act has brought a great number of banks into existence, besides organizing most of the banks formerly existing under State laws under this system; so that we have a nearly uniform system of banking all over the United States. The bills of these banks pass in any part of the country, which was not often the case formerly. In case the bank should be mismanaged, or fail to pay for any cause, there is ample security for their redemption deposited in the United States treasury, where they will be paid on presentation.
