"But I shan't be among strangers, either," interrupted Oscar, handing his mother a package of papers which he drew from the inside pocket of his coat. "There are my credentials, my instructions, which tell me just where to go and what to do, and letters of introduction to high government officers, both civil and military. You see, Professor Kendall—he is the geologist, you know—has taken two parties of students out to the plains, and during his excursions he made the acquaintance of these officers, who gave him every assistance. These letters will bring me the same aid and comfort. The professor is going to take another party out there next summer, and I am going to arrange matters so that they can camp with me for a few days."
The conversation was kept up until midnight, and when Oscar went to bed he had the satisfaction of knowing that, although his mother could hardly bear the thought of so long a separation, she would adhere to her promise and throw no obstacles in his way.
He set about making preparations for the journey as soon as he arose the next morning, and when Monday came he was all ready to start.
His friend Sam, who went around looking as though he had lost everything on earth that was worth living for, was with him night and day, and accompanied him when he went to say good-by to his friends.
Early on Monday morning the omnibus drew up before the door. Oscar assisted the driver to carry out his trunk, and then went back to take leave of his mother.
This was by no means an easy thing to do, and when he came out he held his handkerchief to his face.
The only other passenger was Sam Hynes, who did not speak to or even look at him, although Oscar walked to the forward end of the vehicle, where his friend was sitting, and took a seat by his side.
He resolutely kept his back turned, and looked steadily out of the window until they reached the depot; then he jumped up, wrung Oscar's hand for a moment, and started for the door.
"Say good-by, Sam, and tell me that you wish me success," cried Oscar.
