"THE PROFESSOR!"

Loud and long drawn out was that weird cry of the night. It sent shivers down the spines of Nort and Dick, and they both confessed, afterward, that if they had not been wearing the heavy range hats, supplied them by Bud, that their hair would surely have risen and stood up straight.

Then, as suddenly as it had come to them out of the half darkness, the fiendish noise ceased, dying away in what seemed to be sobbing, insane laughter. With a swallow or two, to wet his parched lips and fear-dried throat, Dick asked in a whisper:

"What—what was that?"

Like an echo came his brother's question:

"Was somebody killed?"

Bud's hearty laugh relieved the tension.

"It was only a coyote," said the boy from the ranch.

"A coyote!" repeated Nort and Dick in unison.

"Yes; you'll see plenty of 'em, and you must have heard of 'em. Little animals, sort of half wolf, half dog. They hang about for something to eat, and they sure can howl!"
