"The desert route is the shortest, and the courier says there is water in the Hole-in-the-Plain. There was a rainfall there last week. That will give you water at the end of each day's drive."

I returned to my rooms and looked over an itinerary of the route, with a schedule of the distances, and other useful information. After making myself familiar with all its peculiarities, I told Frank and Henry that if they desired to do so they might accompany me.

They were overjoyed at the prospect. Henry caught Vic by the forepaws and began to waltz about the room. Then, sitting down, he held her head up between his palms and informed her that she was going to bring back Sancho and Chiquita.

"I do not intend to take Vic, Henry," I said.

"Not take Vic? Why not, sir?"

"The road is long and weary—six days going and six returning, over a rough and dry region—and she will be in the way and a constant care to us."

"But how are we going to find our horses without her? She always helps whenever we are in trouble, and she will be sure to assist us in this if we take her," said Sergeant Henry, emphatically.

"She need be no care to you, sir," said the elder boy; "Henry and I will look after her."

"I am sorry to disappoint you, boys, but I cannot take the dog. She will be left with Captain Bayard."

This decision made the boys somewhat miserable for a time. They commiserated the dog over her misfortune, and then turned their attention to preparations for the journey.
