"How can you talk of people escaping toward the mountains if they had to encounter these?" demanded the President.

"Some of these rocks have undoubtedly been brought down by the torrents," Professor Pludder replied, "but I believe that the greater number fell earlier, during the earthquakes that accompanied the first invasions of the sea."

"But those earthquakes may have continued all through."

"I do not think so. We have felt no trembling of the earth. I believe that the convulsions lasted only for a brief period, while the rocks were yielding to the pressure along the old sea-coast. After a little the crust below adjusted itself to the new conditions. And even if the rocks fell while people were trying to escape from the flood below, they must, like the water, have followed the gorges and hollow places, while the fugitives would, of course, keep upon the ridges."

Whatever perils they may have encountered, people had certainly escaped as the professor had averred. When the party, in the middle of the day, were seated at their lunch, on an elevated point from which they could see far over the strange ocean that they had left behind them, while the southern buttresses of Pike's Peak rose steeply toward the north, they discovered the first evidence of the existence of refugees in the mountains. This was a smoke rising over an intervening ridge, which their new companions declared could be due to nothing less than a large camp-fire.

They hastened to finish their meal, and then climbed the ridge. As soon as they were upon it they found themselves looking down into a broad, shallow cañon, where there were nearly twenty rudely constructed cabins, with a huge fire blazing in the midst of the place, and half a dozen red-shirted men busy about it, evidently occupied in the preparation of the dinner of a large party.

Their friends recognized an acquaintance in one of the men below and hailed him with delight. Instantly men, women, and children came running out of the huts to look at them, and as they descended into this improvised village they were received with a hospitality that was almost hilarious.

The refugees consisted of persons who had escaped from the lower lands in the immediate vicinity, and they were struck dumb when told that they were entertaining the President of the United States and his family.

The entire history of their adventures was related on both sides. The refugees told how, at the commencement of the great rain, when it became evident that the water would inundate their farms and buildings, they loaded themselves with as many provisions as they could carry, and, in spite of the suffocating downpour that filled the air, managed to fight their way to the ridge overhanging the deep cut in which they were now encamped.

Hardly a quarter of those who started arrived in safety. They sheltered themselves to the number of about thirty, in a huge cavern, which faced down the mountain, and had a slightly upward sloping floor, so that the water did not enter. Here, by careful economy, they were able to eke out their provisions until the sky cleared, after which the men, being used to outdoor labor and hunting, contrived to supply the wants of the forlorn little community.
