That May morning was a glorious one. Summer seemed to have burst upon the camp and the noble mountain-sentinels about it.

"We are going to-day," said Sir Charles to his daughter. "Hush! not a word about it to anybody. I have reasons for wishing our departure to be secret."

"You have heard bad news?" asked Mary, quickly.

"Not at all," answered Sir Charles, smilingly. "There is absolutely no cause for alarm. We must go quietly; when we reach home I will tell you my reasons and then we will have a hearty laugh together."

Mary Lackington set about packing her effects, and all the time her thoughts were of her lonely friend in the hill-side cabin. In this hour of her departure she felt herself drawn even more strangely and tenderly toward that weird, incomprehensible creature; such a tugging at her heart the girl had never experienced till now. What would Miss Woppit say—what would she think? The thought of going away with never so much as a good-by struck Mary Lackington as being a wanton piece of heartlessness. But she would write to Miss Woppit as soon as ever she reached home—she would write a letter that would banish every suspicion of unfeelingness.

Then, too, Mary thought of Hoover; what would the big, honest fellow think, to find himself deserted in this emergency without a word of warning? Altogether it was very dreadful. But Mary Lackington was a daughter who did her father's bidding trustingly.

Three-fingered Hoover went with Jim Woppit that day. There were thirteen in the posse—fatal number—mounted on sturdy bronchos and armed to the teeth. They knew their business and they went gayly on their way. Around the mountain and over the Tin Cup path they galloped, a good seven miles, I 'll dare swear; and now at last they met up with the main road, and at Jim Woppit's command they drew in under the trees to await the approach of the party in the stage.

Meanwhile in camp the comedy was drawing to a close. Bill Merridew drove stage that day; he was Steve Barclay's pardner—pretty near the only man in camp that stood out for Steve when he was suspicioned of being in some sort of cahoots with the robbers. Steve Barclay's arm was still useless and Bill was reckoned the next best horseman in the world.

The stage drew up in front of the Mears House. Perhaps half a dozen passengers were in waiting and the usual bevy of idlers was there to watch the departure. Great was the astonishment when Sir Charles and Mary Lackington appeared and stepped into the coach. Everybody knew Sir Charles and his daughter, and, as I have told you, it had been given out that they were not to leave the camp until the morrow. Forthwith there passed around mysterious whisperings as to the cause of Sir Charles' sudden departure.

It must have been a whim on Barber Sam's part. At any rate, he issued just then from Casey's restaurant across the way, jaunty and chipper as ever. He saw Sir Charles in the stage and Bill Merridew on the box. He gave a low, significant whistle. Then he crossed the road.
