The railroad had surveyed a new line through the property, and it had doubled in value.

Sharp, the land agent, did not communicate with her in any way until he had filed his papers, rushed his claim through the departments and into the patent room for patenting.

Then he wrote her a letter, offering her the choice of buying from him or vacating at once.

He received no reply.

One day he was looking through some files and came across the missing certificate. Some one, probably an employee of the office, had by mistake, after making some examination, placed it in the wrong file, and curiously enough another inadvertence, in there being no record of its filing on the wrapper, had completed the appearance of its having never been filed.

Sharp called for the file in which it belonged and scrutinized it carefully, fearing he might have overlooked some endorsement regarding its return to the office.

On the back of the certificate was plainly endorsed the date of filing, according to law, and signed by the chief clerk.

If this certificate should be seen by the examining clerk, his own claim, when it came up for patenting, would not be worth the paper on which it was written.

Sharp glanced furtively around. A young man, or rather a boy about eighteen years of age, stood a few feet away regarding him closely with keen black eyes. Sharp, a little confused, thrust the certificate into the file where it properly belonged and began gathering up the other papers.

The boy came up and leaned on the desk beside him.
