"If I were in your place, I would swear out a warrant for his arrest, and send an officer after him."

"I may be forced to do so."

"And I advise you to keep your eye on Wat Snell."

"I will do that."

"In the meantime, let me take the ring long enough to make an enlarged drawing of those lines, so that you will have the map, if it is a map, even if you lose the ring. You know my ability to copy with pen and ink anything I see. My father wants me to become a civil engineer, and so I am taking a course to suit him; but, when I leave Fardale, I mean to go to an art school, and find out if I am not cut out for an artist."

"How can you make a drawing of the lines?"

"Why, I will place the ring under a microscope, and then it will not be difficult. You know I can be very accurate when I try."

"Yes, I know it, and I will think of your plan. I am inclined to believe it is a good one. Whether I should lose the ring or not, I'd like to have a copy of that map to study."

"I'll find time to do the job to-morrow, if Old Gunn will permit us to use the microscope again."

On the following day, however, Bart found no opportunity to make the drawing.
