report at the fort any lawless deeds that may be done, for I know that
your support will be prompt."

Then the two parted, Buffalo Bill taking the trail for Fort Faraway and
Doctor Dick going on to Last Chance mining-camp.

But hardly had the scout disappeared from sight when the doctor halted,
looked back and then slowly returned to the camp.

Dismounting by the grave, he stood gazing at the inscription cut into
the tree for some minutes, and then turned his eyes upon the mound at
his feet.

"Wicked, yes, hated and feared, yet my brother, and I loved him and my
other brother, Manton, with a love that was greater than woman's love,
and I revere their memory now.

"Whatever they were, whatever the crimes that led to their losing their
lives, I must avenge them, and I will, for Wallace Weston's hand it was
that did the deed.

"Yes, he killed Manton, and I am just as sure that he killed Hugh, who
lies here at my feet. Buffalo Bill believes Wallace Weston dead; _but I
do not_!

"No, I can never believe that he could die except by my hand, and some
day we two will meet face to face, and then he will die, and I will be
avenged for Manton's and Hugh's deaths; so here I vow to take the life
of Wallace Weston, and thus avenge my brothers."

He raised his right hand as he spoke, pressed his left over his heart
and so registered his vow of revenge.

Then, mounting his horse, he rode away upon the trail he had before
followed.

He seemed in no hurry, rode slowly, made long noonday camps and camped
early at night, so that it was the afternoon of the third day before he
came in view of the scattered settlement of Last Chance Claim.

Situated in a mountain canyon, which widened into a large valley after
some miles, with towering cliffs, rugged passes and wild, picturesque
scenery upon all sides, Last Chance Claim, or mining-camp, was scattered
along for miles, the village portion, where the hotel, stores, and
gambling-saloons were, being at the upper end.

As he came out of a mountain pass into the valley proper, Doctor Dick
beheld crowds of miners hastening toward the hotel, and all were
carrying their rifles and had an excited air.

"Well, pards, what has happened?" he asked as he put spurs to his horse
and overtook a party of miners on the way to the hotel.

The response he received caused him to spur forward and dash rapidly on
to the head of the valley.
