"Oh, I'm sure that is so, Mr. Holmes. I know there must be many western men in the east, only they haven't found themselves yet."

He laughed heartily as he rose to go. "Will you ever bid me good night in your language of the desert?" he asked.

"Perhaps, when you have learned that language," she said with an answering smile.

"By George, I shall try to learn it," he answered.

"Oh, I wish you would," came the earnest answer. "I know you could."

And again the engineer felt strongly, back of her words, that unvoiced appeal. As he went down the street he knew that she did not refer to the Spanish tongue when she wished him to learn the language of her Desert.

Alone in her room that night Barbara's mind was too active for sleep and she sat for a long time by the open window, looking out into the vast silent world under the still stars.

Until she introduced herself to Willard Holmes, Barbara had never known eastern people. Tourists she had seen and, at rare intervals, met in a casual way. But they had always examined her with such frankly curious eyes that she had felt like some strange animal on exhibition and had repaid their interest with all the indifference she could command. Occasionally also she had been introduced to eastern business men, whom she chanced upon talking with her father in the bank, but they had turned quickly away to the matters of their world after the usual polite nothings demanded by the introduction. The home-land and life of Willard Holmes were as foreign to her as her land and life were strange to him.

So it happened in this instance also that in the education of the eastern engineer the teacher learned quite as much as the pupil.

The traits that stood out so prominently in the western men whom Barbara knew and so much admired were, in Willard Holmes, buried deeply under the habits and customs of the life and thought of the world to which he belonged—buried so deeply that the man himself scarcely realized that they were there and so was led to wonder at himself when his blood tingled with some strong presentation of this western girl's views.
