calls may be made singly or together during evenings unless some other time has been arranged by appointment.

Do not go away if you find visitors already present. Knowck if the door is closed, tapping loud enough to be heared or ringing the bell if there is one and send your in card or enter.

The question whether a senior officer should make a social call first or junior officer. This depends on the circumstances. A senior officer newly posted to a station should, , unless there is a great disparity in rank, call socially on a junior who will of course have first called on him officially. Wherethe ranks gently differ, the junior should call first. In the  case of superior officer, a junior officer will always call first socially. Call should never be made before 9 am and after 7.30 pm except on prior appointment.

Call should be made between 6 pm and 7.30 pm depending in the season. The first call should not last more than 15 or 20 minutes. Latern, when friendly calls are made, these may be last as long as may be appropriate to the occasion, always providing that you do not overstay and keep your hosts from meal and other engagements. It is good idea to ask in due course whether you are keeping them from  any engagement.

Calls should be retured in person as early as possible. If there is great difference in status or if there is on a mess, the return call will usually take the form of an invitation to a meal.
