"If he had lived thirty seconds longer, I should have learned his secret—should have known how to reach the lost mine by aid of the chart. Now——"

"You may be able to reach the mine after all," said Bart, encouragingly. "You have the ring, and you know its value. When you leave school, you may go West and search for your mine, for it certainly belongs to you now. You may find somebody in the Santa Catarina region that will recognize this portion of the country depicted here."

"Long before that the mine may be found by some one else."

"It is possible, but hardly probable. If it were so easy to find, that man would not have made such desperate attempts to obtain possession of the ring."

"Well, I am not going to kick. I have the ring, and his knife did not end my life, as it would if I had not dodged. He slit open my sleeve from the shoulder to the elbow, and brought the blood."

"Oh, you're a lucky dog," laughed Bart. "You are sure to come out on top every time."

Wat Snell found it convenient to take a vacation, but he returned to the academy later, although he found himself regarded with scorn by all save a certain few of his own sort.

Had Frank seen fit, he could have had Wat expelled; but it seemed that, if the fellow had any sense of shame, the way he was treated by the other cadets was quite punishment enough.

Sometimes Frank and Bart would get out the drawing the latter boy had made from the lines on the ring, and they would study over it a long time, but they always found it baffling, and they finally gave up in despair.

Still Frank clung to both ring and chart, hoping they would some day prove valuable to him.
