Presently two tall smoke-stacks separated themselves from the darkness and appeared high above their heads.

"Ahoy there, boys!" shouted the captain's voice from the bridge.

"Ay, ay, sir!" answered Frank.

"Get ready to come on board! Below there—stand by to lower gang-plank! Now!—lower away!"

Down came the plank, and a joyous group of friends walked down to the shore to greet the boys and the soldier.

A few moments afterwards the boy sergeants led their ponies on board, and Private Tom Clary escorted the prisoners. The Cocopah cleared away and paddled back to the La Paz side, where Texas Dick and Juan Brincos were turned over to the civil authorities, and Sancho and Chiquita to the escort in Mr. Gray's corral.

Three days later the boys and I took leave of Mr. Hudson, who was now in charge of the government storehouse, and, accompanied by Mr. Gray, started for Fort Whipple. Hanging under the hind axle of the ambulance was a ten-gallon keg, and inside was another. We left La Paz early in the morning and arrived at Tyson's Wells at nine o'clock. Remaining there until six o'clock in the evening, we watered our animals, and with freshly filled kegs started for Hole-in-the-Plain, where we stayed until the following evening, the animals passing the day on grass without water. A second night-drive brought us to Cisternas Negras, and the third to Date Creek, from which last point we resumed travelling by daylight.

At Skull Valley, at the earnest request of Miss Brenda Arnold, Henry was allowed to remain for a few days' visit. He promised to join the next incoming mail-rider, and to ride back to the fort by way of the mountain-trail.
