THE August days had slipped away one after another, and September was at hand. There was no perceptible change of weather to mark the advent of the new month. The hills were a little browner, the dust a little deeper, the fleas a little nimbler, and the water in the brook a trifle lower, but otherwise Dame Nature did not concern herself with the change of seasons, inasmuch as she had no old dresses to get rid of, and no new ones to put on for a long time yet; indeed, she is never very fashionable in this locality, and wears very much the same garments throughout the year. [Picture: Round the camp-fire] Elsie seemed almost as strong as any of the other girls now, and could enter with zest into all their amusements. The appetite of a young bear, the sound, dreamless sleep of a baby, and the constant breathing in of the pure, life-giving air had made her a new creature. Mrs. Howard and Jack felt, day by day, that a burden of dread was being lifted from their hearts; and Mrs. Howard especially felt that she loved every rock and tree in the cañon. It was a charming morning, and Polly was seated at the dining-room table, deep in the preparation of a lesson in reading and pronunciation for Hop Yet. Her forehead was creased with many wrinkles of thought, and she bit the end of her lead-pencil as if she were engaged in solving some difficult problem; but, if that were so, why did the dimples chase each other in and out of her cheeks in such a suspicious fashion? She was a very gentle, a very sedate Polly, these latter days, and not only astonished her friends, but surprised herself, by her good behaviour, her elegant reserve of manner, her patience with Jack, and her abject devotion to Dicky. ‘I’m afraid it won’t last,’ she sighed to herself occasionally. ‘I’m almost too good. That’s always the way with me—I must either be so bad that everybody is discouraged, or else so good that I frighten them. Now I catch Bell and Elsie exchanging glances every day, as much as to say, “Poor Polly, she will never hold out at this rate; do you notice that nothing ruffles her—that she is simply angelic?” As if I couldn’t be angelic for a fortnight! Why I have often done it for four weeks at a stretch!’ Margery was in the habit of giving Hop Yet an English lesson every other day, as he had been very loath to leave his evening school in Santa Barbara and bury himself in a cañon, away from all educational influences; but she had deserted her post for once and gone to ride with Elsie, so that Polly had taken her place and was evolving an exercise that Hop Yet would remember to the latest day of his life. It looked simple enough:— 1. The grass is dry. 2. The fruit is ripe. 3: The chaparral is green. 4. The new road is all right. 5. The bay-‘rum’ tree is fresh and pretty. But as no Chinaman can pronounce the letter ‘r,’ it was laboriously rendered thus, when the unhappy time of the lesson came:
