The Round Lake Hose Company was founded in 1886 as the M.B. Sherman Hose Company, with a Constitution that required active members have ‘good moral character’ and live within a mile of the community. The first firehouse was situated on Troy Avenue near the intersection of Burlington Avenue. A two-wheeled cart carried two sizes of hose, which were rolled up on a wheel axle and had a long pole with enough handles for seven men to pull it along if necessary. Another two wheeled cart, with a bell mounted on the axle, would proceed ahead of the hoses to sound a warning.
