Every association which shall have failed to pay up its capital stock, as required by law, and every association whose capital stock shall have become impaired by losses or otherwise, shall, within three months after receiving notice thereof from the Comptroller of the Currency, pay the deficiency in the capital stock, by assessment upon the shareholders pro rata for the amount of capital stock held by each; and the Treasurer of the United States shall withhold the interest upon all bonds held by him in trust for any such association, upon notification from the Comptroller of the Currency, until otherwise notified by him. If any such association shall fail to pay up its capital stock, and shall refuse to go into liquidation, as provided by law, for three months after receiving notice from the comptroller, a receiver may be appointed to close up the business of the association, according to the provisions of section 192 of this title. And provided, That if any shareholder or shareholders of such bank shall neglect or refuse, after three months’ notice, to pay the assessment, as provided in this section, it shall be the duty of the board of directors to cause a sufficient amount of the capital stock of such shareholder or shareholders to be sold at public auction (after thirty days’ notice shall be given by posting such notice of sale in the office of the bank, and by publishing such notice in a newspaper of the city or town in which the bank is located, or in a newspaper published nearest thereto,)  to make good the deficiency, and the balance, if any, shall be returned to such delinquent shareholder or shareholders.
