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. "A right interesting office, sir!" he said. "I have never been in here before. All those papers, now, they are about lands, are they not? The titles and deeds, and such things?" "Yes," said Sharp. "They are supposed to contain all the title papers." "This one, now," said the boy, taking up Bexar Scrip No. 2692, "what land does this represent the title of? Ah, I see 'Six hundred and forty acres in B---- country? Absalom Harris, original grantee.' Please tell me, I am so ignorant of these things, how can you tell a good survey from a bad one. I am told that there are a great many illegal and fraudulent surveys in this office. I suppose this one is all right?" "No," said Sharp. "The certificate is missing. It is invalid." "That paper I just saw you place in that file, I suppose is something else--field notes, or a transfer probably?" "Yes," said Sharp, hurriedly, "corrected field notes. Excuse me, I am a little pressed for time." The boy was watching him with bright, alert eyes. It would never do to leave the certificate in the file; but he could not take it out with that inquisitive boy watching him. He turned to the file room, with a dozen or more files in his hands, and accidentally dropped part of them on the floor. As he stooped to pick them up he swiftly thrust Bexar Scrip No. 2692 in the inside breast pocket of his coat.
