The most interesting of the frequenters of the Hole is a Slav from Trieste, on the Adriatic. He is a genius in his way, and full of energy and business sense. His vocation is that of a "lightning-sketch artist," performing at the theatres. He has travelled all over America and Europe, and is thoroughly hardened to the ways of the world. Whenever he runs out of money he goes up to the Rue de la Gaieté and gives exhibitions for a week or two at one of the theatres there, receiving from fifty to sixty francs a week. The students all go to see him, and make such a noise and throw so many bouquets (which he returns for the next night) that the theatrical managers, thinking he is a great drawing-card, generally raise his salary as an inducement to make him prolong his stay when he threatens to leave. But he is too thoroughly a Bohemian to remain long in a place. Last week he suddenly was taken with a desire to visit Vienna. Soon after he had gone four pretty Parisiennes called and wanted to know what had become of their amant. D------, another of the habitués of the Hole, is a German musical student. Strangers would likely think him mentally deranged, so odd is his conduct. [Illustration: 8175] He has two other peculiarities,--extreme sensitiveness and indefatigable industry. He brings his shabby violin-case every evening, takes out his violin after dinner, and at once becomes wholly absorbed in his practice. If he would play something more sprightly and pleasing the other habitués of the Hole would not object; but he insists on practising the dreariest, heaviest, and most wearing exercises, the most difficult études, and the finest compositions of the masters. All this is more than the others can bear with patience always; so they wound his sensibilities by throwing bread and napkin-rings at him. I hen he retires to the kitchen, where, sitting on the cooler end of the range, he practises diligently under Madame Morel's benevolent protection. This is all because he has never found a concierge willing to permit him to study in his room, so tireless is his industry. If I do not mistake, this strange young man will be heard from some day. Then there is W------, a student in sculpture, with exceptionally fine talent. He had been an American cowboy, and no trooper could swear more eloquently. He has been making headway, for the Salon has given him honorable mention for a strong bronze group of fighting tigers. His social specialty is poker-playing, and he has brought the entire Hole under the spell of that magic game. Herr Prell, from Munich, takes delight in torturing the other habitués with accounts of dissections, as he is a medical student at the Académie de Médecine. The Swede, who drinks fourteen absinthes a day, throws stools at Herr Prell, and tries in other ways to make him fight; but Herr Prell only laughs, and gives another turn of the dissection-screw.
