“Never mind about the whisky, Phelim—I suppose there’s enough to last us for this night, and fill our flasks for the journey of to-morrow. Look alive, old Ballyballagh! Let us stable the spotted mare; and then I shall have time to talk about a fresh supply of ‘potheen,’ which I know you like better than anything else—except yourself!”

“And you, Masther Maurice!” retorted the Galwegian, with a comical twinkle of the eye, that caused his master to leap laughingly out of the saddle.

The spotted mare was soon stabled in the shed, Castro being temporarily attached to a tree; where Phelim proceeded to groom him after the most approved prairie fashion.

The mustanger threw himself on his horse-skin couch, wearied with the work of the day. The capture of the “yegua pinta” had cost him a long and arduous chase—such as he had never ridden before in pursuit of a mustang.

At least, so thought Phelim: who—with the freedom of that relationship known as “foster-brother”—had at length determined on questioning his master as to the cause of his inquietude. As the latter lay shifting from side to side, he was saluted with the interrogatory—
