A library of books had been written on the subject of the telescribe within two years of its advent, but a general description may be outlined untechnically in a page or two. It was, for the moment, the last word of wireless telegraphy. It was efficient, it was speedy, it was cheap, and it transmitted in facsimile. It had passed the stage of being wondered at and had reached that of being used. It was universal. It was universal, that is, not in the sense that tongues are universally in heads, for instance, but, to search for a parallel, as universal as letter-boxes are now on doors, book-cases in houses, or cuffs around men's wrists. There were, in point of number, about three millions on the index book. It was speedy because there was no call required, no intervention of a connecting office to wait for. That was purely automatic. Above the telescribe box in one's hall, study, or sitting-room, was a wooden panel studded with eight rows of small brass knobs, sixteen knobs in each row. These could be depressed or raised after the manner of an electric light stud, and a similar effect was produced: a connection was thereby made. All the country--England and Wales--was mapped out into sixteen primary divisions, oblong districts of equal size. The top row of brass knobs corresponded with these divisions, and by pulling down any knob the operator was automatically put into communication with that part of the system, through the medium of the huge central station that reared its trellised form, like an Eiffel Tower, above the hill at Harrow, and the subsidiary stations which stood each in the middle of its division. The second stage was reached by subdividing each primary division into sixteen oblong districts, and with these the second row of knobs corresponded. Six more times the subdividing process was repeated, and each subdivision had its corresponding row. The final division represented plots of ground so small that no house or cottage could escape location. Pulling down the corresponding studs on the eight rows instantly and automatically established the connection. The written communication could then be transmitted, and in the twinkling of an eye it was traced on a sheet of paper in the receiving box. There was no probability of the spaces all being occupied with telescribes for some years to come. A calculation will show that there was provision for a good many thousand million boxes, but only three million were fixed and attuned at this period.
