We hear from Charlestown, South-Carolina, that on the 21st of March, at night, about eight hundred stand of small arms, two hundred cutlasses, and all the cartouch boxes, fit for service, with several bundles of match and some flints, were taken out of the public armoury in the state-house; and on the same night the public powder magazine, built about four miles from the town, was broke open, and all the powder carried off, being about five hundred weight. The Governor has offered a reward of one hundred pounds sterling for apprehending the offenders.
