When he entered the apartments of the Pittsburg party at six o'clock, Mrs. Whitney reproached him for his absence during their month at Glen Tarn, and in Mrs. Whitney's manner, peremptorily. "I'm sure we've missed seeing everything worth while about here," she complained. Her annoyance put Glover in good humor. Marie met him with a gentler reproach. "And we go next week!" "But you've seen everything, I know," he protested, answering both of them. "Whether we have or not, Mr. Glover should be penalized for his indifference," suggested Marie. Doctor Lanning came in. "Compel him to show us something we haven't seen around the lake," suggested the doctor. "That he cannot do; then we have only to decide on his punishment." "Oh, yes, I want to be on that jury," said Gertrude, entering softly in black. "But is this Pittsburg justice?" objected Glover, rising at the spell of her eyes to the raillery. "Shouldn't I have a try at the scenery end of the proposition before sentence is demanded?" "Justify quickly, then," threatened Marie, as they started for the dining-room; "we are not trifling." "Of course you've been here a month," began Glover, when the party were seated. "Yes." "Out every day." "Yes." "The guides have all your money?" "Yes." "Then I stake everything on a single throw----" "A professional," interjected Doctor Lanning. "Only desperate gamesters stake all on a single throw," said Gertrude warningly. "I am a desperate gamester," said Glover, "and now for it. Have you seen the Devil's Gap?" A chorus of derision answered. "The very first day--the very first trip!" cried Mrs. Whitney, raising her tone one note above every other protest. "And you staked all on so wretched a chance?" exclaimed Gertrude. "Why, Devil's Gap is the stock feature of every guide, good, bad, and indifferent, at the Springs." "I have staked more at heavier odds," returned Glover, taking the storm calmly, "and won. Have you made but one trip, when you first came, do you say?" "The very first day." "Then you haven't seen Devil's Gap. To see it," he continued, "you must see it at night." "At night?" "With the moon rising over the Spanish Sinks." "Ah, how that sounds!" exclaimed Marie. "To-night we have full moon," added Glover. "Don't say too lightly you have seen Devil's Gap, for that is given to but few tourists." "Do not call us tourists," objected Gertrude. "And from where did you see Devil's Gap--The Pilot?" "No, from across the Tarn."
