Schreiner, a cotton farmer, agreed over the telephone to sell 150 bales of cotton to Loeb & Co. Schreiner had sold cotton to Loeb & Co. for the past five years. Written confirmation of the date, parties, price, and conditions was mailed to Schreiner, who did not respond to the confirmation in any way. Four months later, when the price of cotton had doubled, Loeb & Co. sought to enforce the contract.

Is the contract enforceable?
