The Buffalo Post-office was kept, during Mr. Granger's term of office, first on Main Street, near where the Metropolitan Theater[D] now stands, and afterwards in the brick house on the west side of Pearl Street, a few doors south of Swan Street, now No. 58 Pearl Street. Mr. Guiteau first kept the office on Main Street, opposite Stevenson's livery stable; then on the west side of Main Street about the middle of the block next south of Erie Street; and afterwards on the northwest corner of Ellicott Square. It was kept in the same place for a short period at the commencement of Judge Russel's term of office, but was soon removed to the northwest corner of the next block above, where it remained until after the appointment of Mr. Dibble. It was removed by Mr. Dibble about 1836, to the old Baptist Church then standing on the corner where the post-office is now kept, and it was kept in that building until after Mr. Haddock took the office. He removed the office to the northwest corner of Main and Seneca Streets, where it remained until it was removed, in August, 1858, into the Government building in which it is now.
The gross receipts of the post-office at Buffalo, for the years given in the following table, have been as follows:
