As Glen hoped and expected, he was assigned to the second division, of which Mr. Hobart was engineer in charge, and Mr. Brackett was assistant. He was a little disappointed that the only position found for him in the division was the very lowest of all in rank and pay. It was that of tapeman, and his duties were to assist the topographer of the party in measuring distances to, or taking the bearings of, prominent objects along the line. Neither could Glen help wishing that Binney Gibbs had not been assigned to the same division as himself. On account of his brilliant record for scholarship and skill with figures, Binney was made rodman, a position that far outranked Glen's and commanded twice his pay. Still, Glen strove hard not to feel envious of this other Brimfield boy. He was altogether too proud of being a member of the expedition on any terms to have room for any other feeling, and he was anxious to be on a friendly footing with Binney, as he was with everybody else. So, when the positions were announced, and the prize scholar was found to hold such a fine one, Glen was the first to tender his congratulations.

Binney received them coldly, merely remarking that they could not very well have given him any lower position, and that he should not have accepted anything less if it had been offered.

Glen only smiled at this, and thought how fortunate it was that he did not feel that way.

As a rodman Binney was allowed the use of a saddle-animal, and a very small mule was assigned to him as his mount. When he went down to the wagons to inspect his new acquisition, he thought he had never seen a more dangerous-looking animal. It laid back its ears and bit at him when he attempted to pat it on the nose, and manifested every other sign of mulish antipathy towards its new master. In spite of all this, the teamster having it in charge assured Binney that it was a perfect lamb, and the rodman, anxious to prove his ability to ride a mule, which some of the boys had doubted, ordered the animal to be saddled.

The man who held the beast while Binney climbed awkwardly into the saddle winked at some of his fellows who were watching the operation, and thrust his tongue derisively into his cheek.

For a few moments the mule did prove a veritable lamb, ambling along so gently that Binney's spirits rose, and he began to imagine himself the rider that he claimed to be. Elated by his success, he even dared to give the bridle reins a shake, say "Get up!" and finally to touch the side of his steed with the spur that, in his pride, he had fastened to one of his boot-heels.

The effect was electrical. In an instant Binney found himself hatless, with both feet out of the stirrups, clinging for dear life to the pommel of the saddle, and wishing himself anywhere but on the back of a mule dashing madly, at full speed, directly into camp.

"Help! help!" he shouted, breathlessly. "Head him off! stop him somebody!"

Once inside that square of tents, the mule did not seem to realize the possibility of again passing beyond them, but tore frantically round and round the inner side of the square, as though it were a circus-ring. Everybody dropped his work and rushed out to witness the comical spectacle.

"Freeze to him, Grip!" cried one.
