The expedition from which she was excluded was one which Jean was not allowed to undertake, either, as Mrs. Corner decided that they were too young for so hard a trip. Miss Helen, Mary Lee, and Nan were the only ones who would go in company of Carter and a guide. The girls could both sit a horse well and were fearless riders, so the journey to the mountains was not an enterprise which they dreaded in the least. Their own mountains might be less formidable but they were wild enough and had been the scene of more than one hardy experience. The trip would be extended to San Bernardino, although the mountain ride would begin from some point along the route.

"I am just wild to get on one of those little burros," announced Mary Lee.

Carter laughed. "Don't be too wild; you may regret it before your journey is over," and sure enough his prophecy came true, for not long after the mountain climb began around huge boulders, up the trail with great trees towering above them, Mary Lee began to feel uneasy, and to lose confidence in her mount. The leaping river, singing, surging, roaring, a hundred toned stream, had to be forded many times, the guide told them, and it was during one of these fordings that Mary Lee realized that she was right in not trusting her burro.

"I believe he is going to lie down," she cried out.

Carter turned his head. "Oh, no, not the dear little burro that you were so wild to ride."

"Stop teasing her," said Nan; "it is bad enough as it is."

"That was mean," Carter acknowledged; "I'll turn back and encourage her." This he did, but Mary Lee would have none of him when she had safely reached dry land, and dismissed him so curtly that he rode on without a word.

When at last a precipitous trail lay before them Mary Lee had lost all faith in the dear little burro, for he had displayed too many peculiarities along the way, and she declared she would not go a step further.
