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. Another description of fuel, employed for the external and not the internal feeding of the animal machine, and quite as evanescent as candy, claims a factory to itself. This is a French invention called the Loiseau Compressed Fuel. To bring it to Philadelphia, the mart of the anthracite region, would seem to be carrying coals to Newcastle. The relation between demand and supply in fuel is happily, for the present, on too sound a basis to leave much room for artificial substitutes. Our anthracite deposits are circumscribed, but bid fair to last until the virtually untouched seams of bituminous and semibituminous coal shall be made amply accessible to every point of consumption. We are not yet in the slightest perceptible danger of the coal-famine that threatens Great Britain. In regard to the accommodations provided outside of the exhibition buildings by individual enterprise for the display of various products and processes of manufacture, it will here suffice to say that they notably exceed the corresponding array at any of the European expositions. Illustrations of the social and industrial life of different races and nations are, on the other hand, inferior to what was seen at Vienna and Paris. Mankind and their manners are more homogeneous within an available circle around Philadelphia than around either of those capitals. The rude populations of the lower Danube, the Don, the Caucasus, the Steppes, Albania, Syria, Barbary, etc. cannot be so fully represented here. That they should be, were it practicable, would be more to their advantage than to ours perhaps, the probability being slight that we should deem it desirable to adopt many of their methods. Nor will the eating and drinking of the nations be so variously illustrated as in the cordon of restaurants that so largely contributed to the spectacular effect at Paris. The French genius for the dramatic was quite at home in arranging that part of the display; and they did not allow the full effect to suffer for want of some artificial eking out. The kibaubs, pilau and sherbet that were served up in fine Oriental style were not in all cases prepared by Turks, Persians and Tunisians. The materials were abundant in Paris for these and any other outlandish dainties that might be called for.
