The range of the apparatus might well be extended, but the principal defect is the lack of an operator for night duty on some ships. The awful fact that the Californian lay a few miles away, able to save every soul on board, and could not catch the message because the operator was asleep, seems too cruel to dwell upon. Even on the Carpathia, the operator was on the point of retiring when the message arrived, and we should have been much longer afloat--and some boats possibly swamped--had he not caught the message when he did. It has been suggested that officers should have a working knowledge of wireless telegraphy, and this is no doubt a wise provision. It would enable them to supervise the work of the operators more closely and from all the evidence, this seems a necessity. The exchange of vitally important messages between a sinking ship and those rushing to her rescue should be under the control of an experienced officer. To take but one example--Bride testified that after giving the Birma the "C.Q.D." message and the position (incidentally Signer Marconi has stated that this has been abandoned in favour of "S.O.S.") and getting a reply, they got into touch with the Carpathia, and while talking with her were interrupted by the Birma asking what was the matter. No doubt it was the duty of the Birma to come at once without asking any questions, but the reply from the Titanic, telling the Birma's operator not to be a "fool" by interrupting, seems to have been a needless waste of precious moments: to reply, "We are sinking" would have taken no longer, especially when in their own estimation of the strength of the signals they thought the Birma was the nearer ship. It is well to notice that some large liners have already a staff of three operators. _Submarine signalling apparatus_ There are occasions when wireless apparatus is useless as a means of saving life at sea promptly. One of its weaknesses is that when the ships' engines are stopped, messages can no longer be sent out, that is, with the system at present adopted. It will be remembered that the Titanic's messages got gradually fainter and then ceased altogether as she came to rest with her engines shut down. Again, in fogs,--and most accidents occur in fogs,--while wireless informs of the accident, it does not enable one ship to locate another closely enough to take off her passengers at once. There is as yet no method known by which wireless telegraphy will fix the direction of a message; and after a ship has been in fog for any considerable length of time it is more difficult to give the exact position to another vessel bringing help.
