Disagreement between the two units of the treasury arose first. It was said, when the loan board issued a letter stating that national banks might organize or adjust laws as an added facility for those seeking to use the new credit system. This suggestion, it appeared, was thoroughly disapproved by Comptroller Crissinger of the currency, who was said to have viewed the action as a move by the loan board to upset a long-established policy of the comptroller's office which had discouraged organization by national banks of any adjunct corporation which would not be subject to supervision under the national banking act. Officials of the farm loan board contended that they would have complete control of the corporations whose organization they had suggested, but that did not satisfy the comptroller's office. Secretary Mellon was said to be prepared to determine whether anything detrimental to the general treasury policy had been done and whether the Lenroot-Anderson sections of the credit law contemplated encouraging the formation of rediscounting corporations under state laws that might prove "dangerous" to the national banking system. Mr. Crissinger was said to have maintained that the farm loan board's suggestion, that the adjunct corporations be organized under state laws, offers to national banks a means of building up institutions where the problems of ascertaining exact financial conditions would be difficult.
