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.  So were costumers.  There was no reason, therefore, why imitations should not be got up capable of serving every purpose, and of giving more amusement than the genuine dishes and divans of Islam would have done.  The negro waiters in the American saloon doubtless outnumbered all the other representatives of the dark or semi-civilized races that appeared in a similar character.  They proved a success, their genial bearing and ever-ready smile pleasing the mass of the guests more than did the triste and impassive Moslem.  The theatrical can just as well be done here, and quant. suff. of Cossacks and Turks be manufactured to order.  Then we have John and Sambo in unadulterated profusion; the former ready at the shortest notice and for very small compensation to indoctrinate all comers in the art of plying the chopsticks, and the latter notoriously in his element in the kitchen and the dining-room, and able to aid the chasse-cafe with a song—­lord alike of the carving-knife, the cocktail and the castanets.
