Watchmen should report at the store each night, and as soon as the store is closed examine the leaving register, to see that each department has signed for everything having been left in perfect order. They should examine at once all doors and windows, seeing that they are securely fastened; also all other entrances to building, and all places where anyone might be concealed. They should report in writing anything irregular occurring during the night, leaving the same at the office, and repeat the report until the irregularity has been attended to. A regular patrol should be made throughout the entire building. An ingenious system of clock registration is made use of in some cases, which indicates upon examination in the morning the different stations each watchman has passed and the exact time of each passing during the entire night. In the event of fire or any other accident occurring during the night, such special instructions should be followed as will meet with the ready response of whatever assistance may be required.
