"Not a bit of it," laughed Mr. Bell; "it is simply alkali water, and when you have drunk as much of it as I have you'll be used to it and not mind it. But I must admit that on first introduction it is rather trying. It is better when it is boiled, though. It seems to lose that acrid flavor."

And so it proved; and Miss Prescott declared that she had never enjoyed a cup of tea so much as the one she drank that evening at supper on the desert. As dusk fell, Juan produced a battered guitar from a case which was strapped to the back of his saddle, and seating himself cross-legged in the midst of a semi-circle of enthusiastic listeners he banged out a lot of Spanish airs.

Then Jimsy danced a jig with incomparable agility and Roy did some tricks with cards and handkerchiefs that were declared superior to anything heretofore seen. But the little entertainment was to come to an abrupt conclusion. So engrossed had they been in its progress that they had not noticed that the sky had clouded over, and that it had suddenly grown insufferably oppressive.

All at once a red glare enveloped the camp. It lasted only for the fraction of a second, but in its brief existence it displayed some very white and alarmed faces.

The electric storm that Mr. Bell had dreaded was upon them.

CHAPTER VI

A DRY STORM

In describing what immediately followed, Peggy has always declared that her sole impression was of continuous "flash and crash."

The first red glare, as a jagged streak of lightning tore across the sky, was followed by an earsplitting thunder roll. Almost instantly the entire heavens became alive with wriggling serpents of light. The criss-cross work of the bolts ranged in hue from a vivid eye-burning blue to an angry red. And all the time the thunder roared and crashed in one unceasing pandemonium. A smell of brimstone and sulphur filled the air. The tethered stock whinnied and plunged about in mad terror.

"Juan, look to the stock!" shouted Mr. Bell above the turmoil. But Juan, at the first crash, had flung himself face downward on the sand and lay there trembling and praying.
