The inventor of the contrivance for welcoming strangers was, it appeared, applying the same idea to machines for discharging many other of the more perfunctory obligations of social intercourse. One being made for the convenience of the President of the United States at public receptions was provided with forty-two buttons for the different States, and others for the principal cities of the Union, so that a caller, by proper manipulation, might, while shaking a handle, be addressed in regard to his home interests with an exactness of information as remarkable as that of the traveling statesmen who rise from the gazetteer to astonish the inhabitants of Wayback Crossing with the precise figures of their town valuation and birth rate, while the engine is taking in water. We had by this time spent so much time that on finally starting for the railroad station we had to walk quite briskly. As we were hurrying along the street, my attention was arrested by a musical sound, distinct though not loud, proceeding apparently from the indispensable which Hamage, like everybody else I had seen, wore at his side. Stopping abruptly, he stepped aside from the throng, and, lifting the indispensable quickly to his ear, touched something, and exclaiming, “Oh, yes, to be sure!” dropped the instrument to his side. Then he said to me: “I am reminded that I promised my wife to bring home some story-books for the children when I was in town to-day. The store is only a few steps down the street.” As we went along, he explained to me that nobody any longer pretended to charge his mind with the recollection of duties or engagements of any sort. Everybody depended upon his indispensable to remind him in time of all undertakings and responsibilities. This service it was able to render by virtue of a simple enough adjustment of a phonographic cylinder charged with the necessary word or phrase to the clockwork in the indispensable, so that at any time fixed upon in setting the arrangement an alarm would sound, and, the indispensable being raised to the ear, the phonograph would deliver its message, which at any subsequent time might be called up and repeated. To all persons charged with weighty responsibilities depending upon accuracy of memory for their correct discharge, this feature of the indispensable rendered it, according to Hamage, and indeed quite obviously, an indispensable truly. To the railroad engineer it served the purpose not only of a time-piece, for the works of the indispensable include a watch, but to its ever vigilant alarm he could intrust his running orders, and, while his mind was wholly concentrated upon present duties, rest secure that he would be reminded at just the proper time of trains which he must avoid and switches he must make. To the indispensable of the business man the reminder attachment was not less necessary. Provided with that, his notes need never go to protest through carelessness, nor, however absorbed, was he in danger of
