Rothermel had his patent “S. T. 1860 X.” beautifully done in white-wash on the south wall of the building, and Moran, who pays more attention to marine work, had “Sea-weed Tonic” tenderly drawn in blue and gold. Bierstadt, the architect, sent a plan for a model brewery. We felt so completely soothed after seeing this much that we didn’t enter the statuary department. We left that for another day, and jumping on a horse-car we made our way over to MACHINERY HALL. Imagine all the machinery the world contains in motion at the same time, and add about five million more machines to that. This will bring you as near the truth as this volume ventures to approach. Fire, smoke, sweat, and labor; whirring and whizzing, banging and clanging, pounding and puffing, tinkling and jingling. One would think there were seventy thousand horses at work instead of the forty we have mentioned. Everything is being manufactured here--from a tooth-brush to a locomotive; from a latch-key to a wash-boiler. Each workman at a machine is attended by another man placed there expressly to answer questions and be interrogated by visitors. These latter men are carried away and revived every hour. The famous individual who took a prize at the Paris Exposition, is here with his wonderful machine. You give him a live rabbit, and in fifty minutes he returns you a felt hat and a Welsh stew. [THE UNDERLAND ROUTE.] Keeley’s Motor was set up here a few days previous to the opening of the Exhibition, but somehow the machine got loose and knocked things into splinters. It dashed through the main entrance, got on the track of the Market Street cars, rushed clean down to the foot of Market Street, destroying everything in its way, and plunged into the Delaware River just eight seconds after leaving Machinery Hall. Workmen were put at dredging for it immediately, and before they gave up hope of recovering it, a telegram was received from Pekin, saying that it had passed through the Emperor’s palace, carrying the roof with it, and vanishing into space. From the hour telegraphed as the time of this occurrence, it was calculated that the machine landed in China just nineteen minutes after it left Elm Avenue. Mr. Keeley ascribed the cause of this freak to one drop of water too much, being in the reservoir. There was another sort of motor on exhibition, however, which seemed especially attractive and novel to the boys. It consisted of nine strips of leather attached to a wooden handle. The improved hotel front-tooth-picker was an object of attention in the American department, as was also the automatic hen for laying egg plants. The patent American awning post rest, a neat pair of extended arms to support a reclining form, was much remarked; and a patent range, “warranted to save half the coal,” was very well spoken of: you buy two of them and you require no fuel at all.
