The Great A. & P. Tea Co. rented a store from Geary. On February 25 the company wrote Geary offering to execute a lease for an additional year, commencing on May 1. At 10:30 a.m. on March 7, Geary wrote a letter containing a lease for the additional year and accepting the offer. On the same day at 1:30 p.m. the company mailed Geary a letter stating that it withdrew the offer to execute the new lease. Each party received the other's letter the following day. Was there an effective acceptance of the offer to make a lease?
