A post-office was established at Mason in the summer of 1838, with E. B. Danforth as postmaster. An office had previously (probably in the same year) been established at Leslie, and Mr. Danforth empoyed William H. Horton to carry the mail from the latter place to Mason, making the trip once a week. Mr. Horton performed that labor for six months, carrying it at first in a handerchief, and afterwards in an old coffee-sack, following the trail between the two places. He received one dollar and twenty-four cents for each trip, making the return journey the same day. In six months the mail had increased in amount to half a bushel, and it was then necessary to use a conveyance. The postmasters have been, since Mr. Danforth, William Hammond, John W. Phelps, Peter Linderman, D. B. Herrington, Frank Sigfried, and F. T. Albright, the latter having held the office since 1867. It is possible that Hiram Converse was also an early postmaster here, and that the foregoing list may not mention all in their order; but it is from the best recollection of those who should know.
