 terror to modern life? Shall a visitor have to be careful what he says in a neighbour's house, in case his words are stored up in some concealed phonograph, just as his appearance may be registered by a detective camera? In ordinary life—no; for the phonograph has its limitations, like every other machine, and it is not sufficiently sensitive to record a conversation unless it is spoken close at hand. But there is here a chance for the sensational novelist to hang a tale upon.

The 'interviewer' may make use of it to supply him with 'copy,' but this remains to be seen. There are practical difficulties in the way which need not be told over. Perhaps in railway trains, steamers, and other unsteady vehicles, it will be-used for communications. The telephone may yet be adapted to work in conjunction with it, so that a phonogram can be telephoned, or a telephone message recorded in the phonograph. Such a 'telephonograph' is, however, a thing of the future. Wills and other private deeds may of course be executed by phonograph. Moreover, the loud-speaking instrument which Edison is engaged upon will probably be applied to advertising and communicating purposes. The hours of the day, for example, can be called out by a clock, the starting of a train announced, and the merits of a particular commodity descanted on. All these uses are possible; but it is in a literary sense that the phonograph is more interesting.

'On, four cylinders 8 inches long, with a diameter of 5,' says Edison, 'I can put the whole of Nicholas Nickleby.' To the invalid, especially, this use would come as a boon; and if the instrument were a loud speaker, a circle of listeners
