"I wonder if it was the fire Grit was anticipating all the while he acted so queer?" asked Innis.
"I don't know—but it was something," Dick said. "I shouldn't wonder but what he did have some premonition of it. Anyhow, you gave the alarm in time, old boy!" and he patted his pet on the back.
Grit waved his tail, and barked. He seemed himself again.
It took some time to make good the damage done by the fire, and it was accomplished as the airship was put back on her course again, and sent forward toward the Pacific coast. They were all congratulating themselves on their narrow escape from possible failure.
It was that same afternoon, when Mr. Vardon had finished his task, that something else happened to cause them much wonderment.
The motor was again in almost perfect condition, and was running well. Most of the party were out on the deck behind the cabin, enjoying the air, for the day had been hot, and they were tired from fighting the tire.
Suddenly Grit, who was in the pilot-house with Dick, ran out into the main cabin, and, looking from one of the windows, which he could do by jumping up in a chair, he began to bark violently.
"Well, what's the matter now?" demanded Dick. "Is it another fire?"
Grit barked so persistently that Dick called to Paul:
"See what ails him; will you? He must have caught sight of something out of the window."
