John Marshall,
Edmondston v. Drake and Mitchel…
“ In the view which the court takes of the case, it is unnecessary to decide on the first instruction given by the circuit court. If the letter of the 16th of April 1825 was limited to Castillo and Black, that of the 25th of May, unquestionably sanctioned the advances made by Drake and Mitchel on its authority; and made Edmondston responsible for Robson's contract with them. It is on his part a collateral undertaking, which binds him as surety for the Robsons, that they will comply with their contract. No doubt exists respecting his original liability. ”
