But her enthusiasm was not echoed by the others. Even Mr. Campbell, who always felt the heat, sat silent and dejected. Billie, however, usually endeavored to live up to her theories, and she had believed that pure mountain air would act as an instantaneous tonic on their jaded spirits. She was trying now to persuade herself that she was not hot and dusty and excessively weary. They had drawn up in front of a rustic hut built of logs with the bark left on. The roof had a graceful slant from the central peak, and over the gallery in front was another low-hanging roof like the visor of a cap. On one side of the camp, at no great distance from the house, a majestic army of pine trees had ranged itself in the manner of a silent and faithful guard. At the other side, the ledge sloped down in natural, uneven terraces to the valley far below. From the sleeping porches in the back could be seen a broad vista of low country encircled by a wall of mountains, now clothed in a mantle of purple shadows as the sun sank behind the crests of the opposite range. The air was hot and sweet and very dry, and the atmosphere vibrated with the hum of insects like the low, steady accompaniment of stringed instruments in a great orchestra. But at close view, it must be confessed, Nature was very dingy. The pine trees had a rusty look and the parched earth cried out for rain. "Well, ladies, we are here," remarked Mr. Campbell, "and I hope you'll find it to your several tastes." "I am sure we will," answered Mary politely, while the others moved in a silent procession toward the house. Miss Campbell was already wondering how long they could endure this crude and lonely existence a hundred miles from anywhere. The contagion of doubt had indeed spread like a plague over the entire company, and all for the want of a bath, a supper and a good night's rest. "Ah, here are Mr. and Mrs. Lupo," exclaimed Mr. Campbell in a tone of relief, as a man and woman approached down the gallery. "They are half Indians," he added in a low voice. "Mrs. Lupo will be cook and her husband, guide, protector and man of all work." Miss Campbell turned reproachful eyes upon her relative. So then they were to be left in charge of two half-breed Indians in this wild mountainous place, while he was away. Really, men were too incorrigible. But Mr. and Mrs. Lupo, at first glimpse, were far removed from savages. They were, apparently, like two shy, gentle animals with dark, shining eyes, and when they spoke, which was seldom, it was almost as if they had broken a vow of silence. Winter and summer they lived in these high places, and only occasionally did Mrs. Lupo descend to the valley to visit the little shops in the village and look upon the vanities of life.
