"Not plainly, sir; but I think it was one of our own command," and poor Murphy hesitated and stammered. He hated to "give away," as he expressed it, one of his own troop. But his questioners were inexorable.

"What man did this one most look like, so far as you could judge?"

"Well, sir, I hate to suspicion anybody, but 'twas more like Corporal Potts he looked. Sure, if 'twas him, he must ha' been drinkin', for the corporal's not the man to try and run off a horse when he's in his sober sinses."

The waning moon gave hardly enough light for effective search, but we did our best. Blake came out and joined us, looking very grave when he heard the news. Eleven o'clock came, and we gave it up. Not a sign of the marauder could we find. Potts was still absent from the bivouac when we got back, but Blake determined to make no further effort to find him. Long before midnight we were all soundly sleeping, and the next thing I knew my orderly was shaking me by the arm and announcing breakfast. Reveille was just being sounded up at the garrison. The sun had not yet climbed high enough to peep over the Matitzal, but it was broad daylight. In ten minutes Carroll and I were enjoying our coffee and frijoles; Blake had ridden up into the garrison. Potts was still absent; and so, as we expected, was Mr. Gleason.

Half an hour more, and in long column of twos, and followed by our pack-train, the command was filing out along the road whereon "No. 3" had seen the ambulance darting by in the darkness. Blake had come back from the post with a flush of anger on his face and with lips compressed. He did not even dismount. "Saddle up at once" was all he said until he gave the commands to mount and march. Opposite the quarters of the commanding officer we were riding at ease, and there he shook his gauntleted fist at the whitewashed walls, and had recourse to his usual safety-valve,

"'Take heed, my lords, the welfare of us all
Hangs on the cutting short that fraudful man,'

and may the devil fly away with him! What d'ye think he told me when I went to hunt him up?"

There was no suitable conjecture.

"He said to march ahead, leaving his horse, Potts's, and his orderly's, also the pack-mule: he would follow at his leisure. He had given Potts authority to wait and go with him, but did not consider it necessary to notify me."

"Where was he?"
