our engineers and machinists how they manage to lighten their cars, and thereby avoid carrying the excess of dead weight which contributes so much to the annihilation of our tracks and dividends.
The telegraph completes the mastery over space in the conveyance of thought that the railway attains in that of persons and property. Its facilities here are commensurable with its duty of placing thousands of all countries in instantaneous communication with their homes. Those from over-sea will find that, instead of dragging "at each remove a lengthening chain," they are, on the exposition grounds, in point of intercourse nearer home than they were when half a day out from the port of embarkation, and ten days nearer than when they approached our shores after a sail of three thousand miles. To get out of call from the wire it is necessary to go to sea—and stay there. Another hundred years, and even the seafarer will fail of seclusion. Floating telegraph-offices will buoy the cable. Latitude 40° will "call" the Equator, and warn Grand Banks that "Sargasso is passing by." Not only will the march of Morse be under the mountain-wave, but his home will be on the deep.
The submarine and terrestrial progress of the telegraph was in '67 and '73 already an old story. At the Centennial it presents itself in a new role—that of interpreter of the weather and general storm-detector. This application of its powers is due to American science. Indeed, the requisites for experiments were not elsewhere at command. A vast expanse of unbroken territory comprising many climates and belts of latitude and longitude, and penetrated throughout by the wire under one and the same control, did not offer itself to European investigators. These singular advantages have been well employed by the United States Signal Service within the past five years. Its efforts were materially aided by the antecedent researches of such men as Espy and Maury, the latter of whom led European savants into the recognition of correct theories of both air- and ocean-currents. Daily observations at a hundred stations scattered over the continent, exactly synchronized by telegraph, yielded deductions that steadily grew more and more consistent and reliable, until at length those particularly fickle instruments, the weather-vane, the thermometer, the barometer and the magnetic fluid, have formed, in combination, almost an "arm of precision." The predictions put forth in the "small hours" each morning by the central office in Washington assume only the modest title of "Probabilities." Some additional expenditure, with a doubling of the number of stations, would within a few years make that heading more of a misnomer. Meanwhile, the saving of life and property on sea and land already effected is a solid certainty and no mere "probability." At the station on the exposition grounds the weather of each day, storm or shine, in most of the cities of the Old and New Worlds will be bulletined. "Storm in Vlaenderlandt" will be as surely announced to the Dutch stroller on Belmont Avenue as though he were within hearing of his cathedral bell. Should such a "cautionary signal" from beyond the ocean reach him, he may ascertain in what, if any, danger of submergence his home stands, by stepping into one of the branch telegraph-offices dispersed over the grounds. Or he may satisfy all possible craving for news from that or any other quarter in the Press Building. This metropolis of the fourth estate occupies a romantic site on the south side of the avenue and the north bank of the lake. Such a focus of the news and newspapers of all nations was not paralleled at either of the preceding expositions. American journalism will be additionally represented in the different State buildings, where files of all the publications of each commonwealth will be found, embracing in most cases a greater number of journals than the entire continent boasted in 1776, and in each of the States of Ohio, New York and Pennsylvania more than the extra-metropolitan press of either France, Austria, Prussia or Russia can now boast.
The commercial idea is so prominent in this, as in all expositions, that it is difficult to draw the line between public and private interest among its different features, and particularly among what may be called its outgrowths, overflowings or addenda. Here is half a square mile dotted with a picturesque assemblage of shops and factories, among which everything may be found, from a soda-fountain or a cigar-stand up to a monster brewery, all devoted at once to the exemplification and the rendering immediately profitable of some particular industry. In one ravine an ornate dairy, trim and Arcadian in its appurtenances and ministers as that of Marie Antoinette and her attendant Phillises at the Petit Trianon, offers a beverage presumably about as genuine as that of '76, and much above the standard of to-day. A Virginia tobacco-factory checkmates that innocent tipple with "negrohead" and "navy twist." A bakery strikes the happy medium between the liquid sustenance and the narcotic luxury by teaching Cisatlantic victims of baking-powders and salæratus how to make Vienna bread. Recurring to fluids, we find unconquered soda popping up, or down, from innumerable fonts—how many, may be inferred from the fact that a royalty of two dollars on each spigot is estimated to place thirty-two thousand dollars in the strong box of the exposition. Nor does this measure the whole tribute expected to be offered at these dainty shrines of marble and silver. The two firms that bought the monopoly of them pay in addition the round sum of twenty thousand dollars. It speaks well for the condition of the temperance cause that beer is the nearest rival of aerated water. An octroi of three dollars per barrel is estimated to yield fifty thousand dollars, or two thousand dollars less than soda-water. Seventy-five thousand dollars is the aggregate fee of the restaurants. Of these last-named establishments, the French have two. The historic sign of the Trois Frères Provençaux is assumed by a vast edifice in one of the most conspicuous parts of the enclosure, sandwiched between the Press and the Government. The "Sudreau" affects the fine arts and cultivates with like intimacy the society of Memorial Hall. The German refectory, Lauber's, a solid, beery sort of building, shows a fine bucolic sense by choosing a hermitage in the grove between Agricultural and Horticultural Halls. A number of others, of greater or less pretensions, will enable the visitor to exclaim, with more or less truth, toward the dusty evening, "Fate cannot harm me: I have dined to-day."
"Dusty," did we say? The ceaseless sob of engines that rob the Schuylkill daily of six millions of gallons to sprinkle over asphaltum, gravel and greensward demands recantation of the word. Everything has been foreseen and considered, even the dust of the earth. George's Hill Reservoir can, on occasion, give the pumps several days' holiday, and keep all fresh and dewy as the dawn.
Some industries meet us in the Centennial list that are not to be detected in the United States census or any other return we are acquainted with. What train of ideas, for example, is suggested to the average reader by the Roll-Chair Company? The rolling-stock of this association turns out, on inquiry, to be an in-door variety of the conveyance wherein Mrs. Skewton was wont to take the air under the escort of Major Bagstock. It is meant for the relief of those who wish to see everything in the Main Building without trudging eleven miles. Given an effective and economical motive-power, the roll-chair system would seem to meet this want. The reader of Dombey and Son will recollect the pictorial effect, in print and etching, of the popping up of the head of the propellent force when Mrs. S. called a halt, and its sudden disappearance on her directing a resumption of movement. The bobbing up and down of four hundred and fifty heads, like so many seals, will impart a unique aspect to the vista from one of the interior galleries of the great hall. The stipulated tax of forty dollars on each of these vehicles will necessitate a tolerably active undulation of polls if the company is to make both ends meet—granting that a rotatory movement can have an end.
Another startling item is the pop-corn privilege. A business-man of Dayton, Ohio, finds himself justified in venturing the heavy sum of seven thousand dollars on this very light article. Parched corn was well known in Ohio in 1776. The Miamis and Shawnees had, however, a monopoly of it. It composed their commissariat for a campaign against the whites. Such is the progress of the century.
This explosive cereal does not satiate the proverbially sweet tooth of our people. Their craving for confectionery is laid under further contribution by the financial managers of the exposition to the tune, for instance, of five thousand dollars for the privilege of manufacturing chocolate and candy. Dyspepsia insists on asserting its position among the other acquisitions of the century. The treasures of the American bonbonnière are said to be richer and more varied than in any other country. Paris gets up her delicacies of this kind in more tasteful and tempting style, but our consumers care little for such superficial vanities. They look for solid qualities in everything—even in their lollipops.
