"Sure. But what about this? How shall I know if my measurements are correct?" "I'll tell you what we'll do. You scale every pile of logs at the highway and make a record of your measurements. When Lumley turns in his official record we can compare your figures with his. Then you will know how nearly right you are." They went down the mountain and climbed into the motor-car. "Perhaps you would rather do this some other time," said the forester suddenly. "You'll have to walk back, for I must go right along to my office. And it's a great deal farther back here than it would have been to Lumley's house." Charley's reply was a good-natured laugh. "Have you ever found me afraid of a little hike?" he asked. "I may not have another opportunity as good as this, for I'm going to be mighty busy when my crew gets back." They drove on, and at the skidways Mr. Marlin dropped his subordinate. "I'll be out to see you to-morrow," he said, "with some maps and specifications I must work out to-night. Good-bye." "He's a prince," muttered Charley, and fell to measuring logs. Applying his log-rule to the small end of each log, he noted the diameter of the log and from the scale on the rule read the number of board-feet in the log. Already Charley had done a little scaling of logs and he went at the work readily. As he scaled pile after pile of logs, he worked faster and faster, acquiring greater facility with every measurement. The contents of each pile he noted down, a log at a time, on a bit of paper. When he had finished the work, he totaled up the board-feet, and whistled when he realized what a tremendous quantity of lumber was contained in the log piles he had been measuring. "Gee!" he said to himself. "At the price lumber is selling for now, those logs are worth a small fortune. Gad! It makes a fellow feel pretty sober when he thinks how easily he could make a mistake that would cost the state hundreds of dollars."
