The first post office in the township was at Hopkinsville, established in 1825, and afterward post offices were established in the following order viz. : Dallasburg, 1848, Maineville, 1854; Foster's Crossing, 1859; Murdoch, 1866, and Cozaddale, 1871. The very earliest settlers received their mail probably at Lebanon. The following, copied from the address on the back of an early letter, will show how indefinite the directions:

Mr. Samuel Walker,
living in Warren County,
State of Ohio;
Near the Little Miami.

This letter was written in 1805. It will be seen that Southern Hamilton was without an office until 1848, but the postal facilities were not so bad as this would indicate, as there was a post office at O'Banionville in Clermont county, near the Warren line at quite an early date, affording the advantage of a weekly mail to this section. The above offices are, with the exception of Dallasburg, in operation yet, each having a daily mail.
