The jagged streak of electricity seemed to bury itself in the side of the mountain not far from the party and there followed such a crash as seemed to shake the very earth. The horses actually cowered down, too frightened to run.

“That struck somewhere!” exclaimed Ned, in the silence that followed the awful crash.

“I reckon it did,” said Cromley. “I’ve seen storms out here before, but when it gets going and makes up its mind, this is going to put it all over the worst I ever saw.”

“Well, if it’s going to get any worse hadn’t we better do something more than talk about it?” asked Jerry.

“I’m looking for a place of shelter,” Tinny remarked. “The worst of it is, though, that when there’s so much ore scattered about, one place is as bad as another to attract the lightning. But come on.”

After those first few flashes of lightning and terrific crashes the storm seemed to die away; but they all knew it was but a momentary passing, as if to enable the elements to gather strength for a worse outburst. However, even this brief respite gave them a chance to make better time down the mountain trail, for the horses were less inclined to throw their riders and gallop off by themselves.

The sun had begun to sink in the west some time before the first signs of storm were noticed, and now, with the fading of day and the overcasting of the sky with black clouds, the scene was fast darkening. Only one thing was in favor of the travelers, and that was that the trail at this point was broad and easy of travel, though it was steep.

“Is there any particular place you’re heading for?” asked Jerry, as he urged his steed alongside that of Tinny Mallison.

“Yes,” was the answer. “About two miles from here there’s an old cabin just off the trail. It was once owned by a mining company I invested some money in. Invested was all it ever amounted to, for the claim petered out. But the cabin still stands; or did several months ago when I was last over this trail. If we can get there we can be well sheltered and comparatively safe from lightning shocks.”
