We had hardly had time to take in all these peculiarities when Dick once more exclaimed:

"Ah! Here they come! One, two, three—only five of them after all."

As he spoke, the wolves came loping out from among the trees; but the moment they struck our cross-trail the suspicious, wary creatures all stopped with one accord, puzzled by coming upon a scent they had not expected.

This was the Mexican's opportunity. Raising his long left arm, he drew an arrow to its head and let fly.

I thought he had missed, for I saw the arrow strike the ground and knock up a little puff of dust. But I was mistaken. One of the wolves gave a yelp, ran back a few steps, fell down, got up again and ran another few steps, fell again, and this time lay motionless. The arrow had gone right through him!

Almost at the same instant Dick raised his rifle and fired. The shot was electrical. One of the wolves fell, when the remaining three instantly turned tail and ran.

But not only did the wolves run: the Mexican, casting one glance in our direction, sprang upon his donkey and away he went, at a pace that was surprising considering the respective sizes of man and beast.

It was in vain that Dick ran out from under our tree and shouted after him something in Spanish. I could distinguish the word, amigos, two or three times repeated, but the man took no notice. Perhaps he did not believe in friendships so suddenly declared. At any rate, he neither looked back nor slackened his pace, and in a minute or less he and his faithful steed vanished into the timber on the south side of the clearing.

The whole incident had not occupied five minutes; but for the presence of the two dead wolves one would have been tempted to believe it had never happened at all—solitude and silence reigned once more.

"Well, wasn't that a queer thing!" cried Dick.
