Watches

Sweeping changes in the watch bill organization for officers under instruction and staff members of NTS (Communications) have been put into effect and were made known today by Lt. (j.g.) H. H. Hansen, Aide to the Executive Officer.

During each 24-hour period, a total of about 60 men will now stand watches for all companies from B to E as compared with a former watch bill requiring approximately 105 men for the same length of time.

This has been effected, Lt. Hansen explained, by assigning only one guard per building during a watch period, where the number used to run as high as four, depending upon the number of entries. The doors which are not guarded by watches will remain locked day and night except during the periods when students return from classes and are on leave.

The new system permits men to stand a minimum of watches, as low as two watches per month at NTS, and allows those men attending night classes to have a maximum amount of time for studies.

The watch bill is virtually unchanged for Company B which still maintains guard at the Duty Office, the Harvard Yard Watch Office, Harvard Union and Littauer.
