778 HARVARD LAW REVIEW to the satisfaction of the holder when demanded ; on failure to do so the note matures at once, and the holder may exercise his power of sale if he desires.^^ Occasionally, the maker is given the option of paying something on account instead of furnishing more security.^^^ Sometimes, the note provides that the collateral also secures any other obligation of the maker due to the payee, or even of any firm of which he is a member. The peculiar acceleration provisions of the obligations of the National Salt Company will be discussed later.^^ The weight of authority holds these provisions for acceleration by depreciation of collateral to be fatal to negotiability, whether accompanied by a promise to furnish more collateral ^^^ or not.^^^ There is, however, good authority in favor of negotiability.^^^ The provisions are said to violate three formal requisites: cer- tainty of amount, certainty of time, and the rule against a promise to do anything but pay money.
