The men provided themselves with a number of little luxuries at the sutler's—the last store they would see for months—and "Billy" Brackett bought a cheese. This was considered a very queer purchase; but Glen's was queerer still, for it was a small quantity of strychnine. He only procured this after giving assurances that he did not propose to commit suicide and making many promises to be very careful in its use. What he proposed to do with the poison he did not confide to anybody except his friend "Billy" Brackett, who agreed with him that it was a capital plan.

A run of twelve miles from Fort Wingate brought the party to a camp, in a forest of the most stately yellow-pines they had ever seen, beside a great spring of ice-cold water—known as the Agua Fria (cold water). Here, as soon as supper was over, Glen proceeded to put his great plan into execution. The nights were now very cold, and the boy generally woke before morning to find himself shivering beneath his insufficient covering of blankets. Every night, too, since entering the mountains the party had been annoyed by the sneaking visits and unearthly howlings of wolves that hung on the outskirts of the camp from dark to daylight, every now and then making a quick dash through it, if the guard was not watching sharply, and snatching at bits of food or at anything made of leather that lay in their path. So Glen thought he would teach the wolves a lesson, which should at the same time add some of their skins to his bed-clothing; and it was for this purpose he had procured the strychnine.

Now, with "Billy" Brackett's help, he dragged out from one of the wagons a gunny-sack, containing some kidneys, lungs, and other refuse animal matter, obtained from the Fort Wingate butcher, and these he smeared with the deadly powder. Then they prepared several torches of pine slivers, and, amid the unanswered questionings of their companions, left camp, carrying the sack of meat between them. Beginning at a point a few rods from the tents, they strewed the poisoned bait for half a mile along the banks of the little stream flowing from the spring. It was an exciting task, for they seemed to hear suspicious sniffs, and the soft pattering of feet on both sides of them; while Glen felt certain that his torchlight was reflected from gleaming eyeballs more than once. So greatly did these things work upon their imaginations that when, as they started back towards camp, their last torch suddenly went out, leaving them in blackest darkness, they both took to their heels, and raced breathlessly for the distant light of the friendly camp-fire. When they reached it, in perfect safety, they burst out laughing in one another's faces, and wondered what they had run from.

Glen was disappointed, as he lay shivering in his blankets that night, not to hear so many wolves as usual, while the few howls that did reach his ears seemed to come from a distance. Still, he comforted himself with the reflection that dead wolves couldn't howl, and doubtless all those that had ventured near the camp had eaten the poisoned meat, and had their howlings effectually silenced.

It seemed to him that he had hardly dropped asleep when he was rudely awakened by being pulled, feet foremost, out of his blankets, under the side of the tent, and into the open air. At the same moment "Billy" Brackett's laughing voice cried, "Come, Glen, here it is broad daylight, and high time we were gathering in our wolves."

Whew! how cold it was! and in what a hurry Glen sprang from the frozen ground, to rush back into the tent for his boots and army overcoat. He had everything else on, for there was very little undressing at night in that party. As for being sleepy, the biting air had awakened him as effectually as a dash of ice-water.

As they left camp, "Billy" Brackett shouted back to one of the Mexican axemen to follow after them, and the man answered that he would be along in a minute. It was light enough, when they reached the place where they had left the first of the poisoned meat, for them to see it if it had been there; but it was not. Neither was there any dead wolf to be found in the vicinity. It was the same along the whole line, where they had scattered their bait. They could neither discover meat nor wolves.

"Hello!" exclaimed "Billy" Brackett softly, as they were about to turn back, "I believe the wolves are cooking their meat;" and with that he pointed to a thin column of blue smoke rising through the trees at some distance farther down the stream.

"Perhaps they are Indians," suggested Glen.

"Perhaps they are. Let's go and find out. We can take a look at them without being seen. Besides, the Indians hereabout are peaceful now."
