25. Should any interruption of signals from the ship occur by reason of an accident on board, shore will continue to free the Cable at the usual time, and to put to earth direct at the usual time, and in the intervals to put into circuit with the Cable a galvanometer, and watch the same for signals, and continue doing so until communication with the ship is restored, or information is received by other means from the ship. 26. On re-establishment of communication, shore must not ask any questions, but take the resumption of signals as an indication of all being well again, and will continue to follow the series of tests as if nothing had happened. 27. Shore will take time from the ship; should any irregularity in the reception of signals from the ship occur, such irregularity must be entered in journals, and must not form a ground for shore’s altering his time, but shore must follow blindly every change (should one take place), as if the most correct time had been kept. 28. A proper supply of lamps, glasses, oil, and wicks; instrument ink and instrument paper, in sufficient quantities; paraffin, wicks, and spare lamp-glasses for the instrument lamps; lamp-brushes, tools, sulphate of copper, stationery, &c., to be always ready for use. 29. No person, except those on duty, and the officers authorised by the Atlantic Telegraph Company, to be allowed in the instrument room on any pretence. 30. The batteries to be kept in an efficient state, especially those for sending reversals--their force taken periodically, and if any variation occur, they must be renewed, or brought up to the original force. 31. Supplies of all materials necessary for such purpose to be in constant readiness. 32. The actual end of the Cable to be brought to the instrument tables, and well insulated. SHORE SIGNALS. 33. Ordinary.--5 reversals, each two minutes, commencing C to E. 34. To open communication on acknowledgment.--8 reversals, each ¼ minute, commencing Z to E.
