The dusk meanwhile had thickened, and they had not perceived a figure approaching them across the open space in front of the house. Suddenly it stepped into the circle of light projected from the door and windows, and they beheld little Sam Singleton stopping to stare at them. He was the giant whom they had seen descending along the rocks. When this was made apparent Roderick was seized with a fit of intense hilarity--it was the first time he had laughed in three months. Singleton, who carried a knapsack and walking-staff, received from Rowland the friendliest welcome. He was in the serenest possible humor, and if in the way of luggage his knapsack contained nothing but a comb and a second shirt, he produced from it a dozen admirable sketches. He had been trudging over half Switzerland and making everywhere the most vivid pictorial notes. They were mostly in a box at Interlaken, and in gratitude for Rowland’s appreciation, he presently telegraphed for his box, which, according to the excellent Swiss method, was punctually delivered by post. The nights were cold, and our friends, with three or four other chance sojourners, sat in-doors over a fire of logs. Even with Roderick sitting moodily in the outer shadow they made a sympathetic little circle, and they turned over Singleton’s drawings, while he perched in the chimney-corner, blushing and grinning, with his feet on the rounds of his chair. He had been pedestrianizing for six weeks, and he was glad to rest awhile at Engelthal. It was an economic repose, however, for he sallied forth every morning, with his sketching tools on his back, in search of material for new studies. Roderick’s hilarity, after the first evening, had subsided, and he watched the little painter’s serene activity with a gravity that was almost portentous. Singleton, who was not in the secret of his personal misfortunes, still treated him with timid frankness as the rising star of American art. Roderick had said to Rowland, at first, that Singleton reminded him of some curious little insect with a remarkable mechanical instinct in its antennae; but as the days went by it was apparent that the modest landscapist’s unflagging industry grew to have an oppressive meaning for him. It pointed a moral, and Roderick used to sit and con the moral as he saw it figured in Singleton’s bent back, on the hot hill-sides, protruding from beneath his white umbrella. One day he wandered up a long slope and overtook him as he sat at work; Singleton related the incident afterwards to Rowland, who, after giving him in Rome a hint of Roderick’s aberrations, had strictly kept his own counsel. “Are you always like this?” said Roderick, in almost sepulchral accents. “Like this?” repeated Singleton, blinking confusedly, with an alarmed conscience. “You remind me of a watch that never runs down. If one listens hard one hears you always--tic-tic, tic-tic.” “Oh, I see,” said Singleton, beaming ingenuously. “I am very equable.”
