I will now draw this article to a close, well appreciating the fact that I have only made a superficial attempt to instruct younger men in the cleaning and repairing of watches, for there is almost an endless variety of special repairs coming almost unexpectedly to any one, even if they have been in the business a long time, as I have, and as I first said, I am learning daily some new phase of the business, and am surprised that I never had known it before. I have, too, taken perhaps more space than I ought, regarding tools and bench, yet the older I grow, the more I can see the importance of this part, that I may be enabled to do work well and quick. Besides, I have left such repairs as the chain and fusee, uprighting wheels, repairing cases, adjustment to position, heat and cold, isochronism, enlarging jewels, or changing angles of pallet stones, etc., etc., all of which I do as necessity demands, as well as the care of striking watches, fly backs, etc., which, too, I make a specialty of, and of chronometer escapement watches, which would take more space than I feel disposed to ask you to give me.--_American Jeweler._ * * * * * THE NEW CENTRAL RAILWAY STATION AT FRANKFORT ON THE MAIN. The new central railway station at Frankfort on the Main is one of the most imposing structures of modern times, not only as regards its dimensions, but also because of the effect which its architectural proportions produce upon the eye. Nobody looking at the long line of buildings surrounded by gigantic perron halls can help being impressed with their grandeur. The beholder, however, is not only struck by the general aspect, but also by the beauty of detail in this magnificent specimen of the Renaissance style. The interior of the perron hall shown in one of our engravings is especially impressive, and every one will admire the graceful outlines of the heavy iron structures in the upper part, which, in consequence of their enormous height, look from below like a spider web. The base and the earth works were begun in the summer of 1881, and if we take into consideration the fact that 2,700,000 cubic meters of sand and gravel were necessary for the foundation, we will have some idea of the scale on which the edifice was undertaken. In 1883, the great hall, which has a width of 220 meters and which will shortly be opened to traffic, was begun. The perspective view of this portion of the station is given in one of our engravings. Inspector Eggert had the general management of the building, which was erected after the plan submitted by him, and which received the prize in the competition between the different architects. Herr Frantz, a distinguished engineer, who undertook the general supervision of the construction, had an important part in the execution of the entrance hall for the trains, and it was he, also, who built the perron hall, after designs of Herr Schwedler.
