Summer Camps Robbed.

Several of the summer camps on the Turner property on the River Road, north of Koolkill, have been broken into this spring and some valuable articles taken. At “The Hermitage,” Robert L. Miter’s bungalow, a large trunk containing woolen blankets was unlocked and most of its contents removed and then locked again. At Thomas E. Ward’s bungalow the thieves gained entrance to the cellar, but did not secure anything except a few tools. Herbert I. Gifford’s camp was also entered.
