"Fire Companies. — Just when, where, or by whom
the pioneer lire apparatus of the old Columbia Cora*
pany was purchased we cannot ascertain, as the earliest
records are lost or destroyed. However, we find tiiat
the company was organized and owned a fire-engine
as early as February 27, 1806, and an account of one
hundred and fifty dollars having been paid towards
its purchase, and the same year eleven dollars was
charged by the treasurer as having been paid for re-
pairs to the carriage. This is supposed to mean the
hose-carriage, though not definitely stated. In 1814,
at a reorganization of the company, the following
persons were enrolled as members: Samuel Miller,
William F. Houston, William B. Hunt. John Wilson,
John Haldeman, Michael Elder, William F. Beaty,
