Through the open window the various sounds of the city's activity floated rather pleasantly. There was even a note of cheerfulness in the insistent bells of the trolley-cars on Madison Avenue and the chugging of a taxicab on the other side of the street. Before many minutes had gone by a rope ladder dangled outside the window, and this was followed immediately afterwards by the lithe and wiry figure of a boy. Wearing a rather sheepish expression he remained sitting on the sill, swinging his legs. "Hello!" said he. "How are you feeling?" "There's some improvement to-night," said Ethel. "Won't you come in? Were you waiting for a signal?" "You bet!" He was a nice boy, with a frank, honest face, a blunt nose and a laughing mouth. His hair was dark and thick, and his shoulders square. He was eighteen and he looked every day of it. He lived next door and was the son of a man who owned a line of steamships and a French mother, who was not on speaking terms with Mrs. Guthrie, owing to the fact that the Doctor had been obliged to remonstrate about her parrot. This expensive prodigy gave the most lifelike and frequent imitations of cats, trolley-cars, newsboys, sirens and other superfluous and distressing disturbances on the window-sill of the room which was next to his laboratory. So this boy and girl--unconsciously playing all over again the story of the Montagues and Capulets--met surreptitiously night after night, the boy coming over the roof and using the rope ladder--which had played its part in all the great romances. Was there any harm in him? Well, he was eighteen. "What'll you have first?" asked Ethel, in her best hostess manner--"candies or cigarettes?" "Both," said the boy; and with a lump in his cheek and an expression of admiration in both eyes he started a cigarette. He was about to sit on the settee at Ethel's feet, but she pointed to a chair and into this he subsided, crossing one leg over the other and hitching his trousers rather high so that he might display to full advantage a pair of very smart socks, newly purchased. "I hope you locked your bedroom door," said Ethel, "and please don't forget to whisper. There's no chance of our being caught, but we may as well be careful." The boy nodded and made a little face. "If father found out about this," he said; "oh, Gee! What did you do with Ellen after she bounced in last night?" "Oh, I gave her one of my hats. I told her that if she kept quiet there was a frock waiting for her. She's safe. Now, amuse me!"
