"Good; we won't go hungry," said Zeb. "Nothing better than fried eels and catfish."
He greased the frying pan with a strip of bacon rind and then skinned the scaleless catfish and eels as if he had been doing nothing else all his life. Soon the savory odors of the frying with crisp slices of bacon, and the aroma of coffee, filled the camp.
The boys were so busy setting out the tin cups and plates that it was not till Zeb beat on a tin basin with a spoon to announce that the evening meal was ready that anyone noticed that the professor was missing. Night was closing in and the sky was overcast.
The boys began to worry. They set up a loud shout.
"Pro-fess-or! Oh, pro-fess-or!"
The little gulch rang with it. But no answer came.
"Now what in the world has happened to him?" frowned Jack. "We must go and find him at once. He must have——"
The sentence was never completed. At that instant Zeb set up a shout, and a ton of earth and rocks, more or less, came hurtling down the steep bank into the camp. The stones and dirt were mingled with mesquite bushes and in the midst of the landslide was a figure that they made out to be the professor.
Luckily, the avalanche had missed the camp-fire and the supper table, and when they had extricated the professor, and brushed him off, the boys learned that he had almost missed his way, and being shortsighted, in the dark had walked right over the edge of the steepest part of the arroyo instead of by a sloping path up above.
