“It is a bough of the family elm,” explained Mr. Van Nicht. “One of the lower boughs has grown forward and downward, until it touches the side of the house. When stirred by the breeze it creates the sound which you hear.” Internally Olcott shivered. Now that the explanation had been vouchsafed the noise made him think of ghostly fingers tapping at the glass panes--as though the spirit of the tree craved admittance to the dismal circle of these human creatures who shared with it the tribal glory. “Don't you find it very annoying?” he asked innocently. “I should think you would prune the limb back.” He halted then, realising that his tongue had slipped. There was a little silence, which became edged and iced with a sudden hostility. “No human hand has ever touched the tree to denude it of any part of its majestic beauty,” stated Mr. Van Nicht with a frigid intonation. “Whilst any of this household survives to protect it, no human hand ever shall.” From the elder sister came a murmur of assent. The conversation had sagged and languished before; after this it sank to a still lower level and gradually froze to death. After possibly ten minutes more of the longest and bleakest minutes he ever recalled having weathered, Olcott, being mentally chilled through, got up and, making a show of expressing a counterfeit pleasure of having been accorded this opportunity of meeting those present, said really he must be going now. In their places Miss Rachael Van Nicht and her brother rose, standing stiff as stalagmites, and he knew he was not forgiven. It was the younger sister who showed him out, preceding him silently, as he betook himself from the presence of the remaining two. Close up, in the better light of the hall, Olcott for the first time perceived that Miss Harriet Van Nicht was not so very old. In fact, she was not old at all. He had assumed somehow that she must be sered and soured and elderly, or at least that she must be middle-aged. With this establishment he could not associate any guise of youth as belonging. But he perceived how wrong he had been. Miss Harriet Van Nicht most assuredly was not old. She could not be past thirty, perhaps she was not more than twenty-five or six. It was the plain and ugly gown she wore, a dun-coloured, sleazy, shabby gown, which had given her, when viewed from a distance, the aspect of age--that and the unbecoming way in which she wore her hair slicked back from her forehead and drawn up from round her ears. She had fine eyes, as now he saw, with a plaintive light in them, and finely arched brows and a delicate oval of a face; and she was small and dainty of figure. He could tell that, too, despite the fit of the ungraceful frock. At the outer door, which she held ajar for his passage, she spoke, and instantly he was moved by a certain wistfulness in her tones.
