Isabel, who faced him, turned her head. "There are always fires in San Francisco after an earthquake," she said, indifferently. "And about seven a day at any time. There are none on the hills, so your mother is not having a second fright. Poor thing! I am afraid she is terribly upset. I wish she had gone."

She sat about, to observe the city more critically. Already its sky-line was changed, for every chimney, smokestack, and steeple, commonly visible, was shattered or down. The smoke cloud, which looked like a great ostrich plume bent at the tip, was as stationary as the hills, and had a confident permanent air that they would lack for some time. And fixed as it was it seemed to grow larger.

"Steer to the east of Alcatraz," said Isabel, suddenly; "and towards Yerba Buena. I should like to see where the fires are."

When the launch was well off the point of Telegraph Hill, they saw several large fires on the western side of East Street, the wide roadway that divided the city from the water-front and Ferry Building. Far down, in the South of Market Street district there appeared to be other large fires.

"Warehouses, probably," said Isabel. "What a sight!" She indicated the collapsed sheds about the moles, and the twisted and toppling appearance of the tower on the Ferry Building, which stood on the edge of the made ground. It was an immense structure of great weight, and only an uncommon honesty—and vigilance—in building had saved it from destruction. Had the piles been hollow, or too short to reach bed-rock, it would either have sunken or tumbled.

And then they noticed that the bay was silent and deserted. It was a moment before they realized that of the several lines of ferry-boats none appeared to be running. "That means that the tracks are out of working order," said Isabel, grimly. "We may have had the best of it, bad as it was. Ah!" One of the Oakland ferry-boats pushed out of its San Francisco mole. It was black with people. Isabel stared with wonder. "It looks as if people were running away from the city. Or perhaps a good many that live across the bay came over on the same mission as ourselves, and have been turned back. That would mean that all East Street was on fire and they could not get into the city. Well, let us hurry. Even although the fires are so far off they may terrify your mother. I remember she told me once in England that she had never seen a fire. I have a queer sensation in my knees."

Gwynne laughed. "I should think you might be used to fires by this time. And you have a celebrated fire department. I fancy you are just feeling the reaction."

"I was not a bit frightened during the earthquake!" said Isabel, indignantly. "But there is nothing phenomenal in fire to brace one up—and those had a sinister determined look—and that boat-load of people! I only hope your mother has not run away—under the impression that San Francisco alone was shaken. We wouldn't find her for a week."

"My mother's nerves are not what they were, but I am positive she will not run. She is certain to wait for us at the house."

A few moments later they ran the launch up to the landing at the foot of Russian Hill. There were a few tumbled shanties on the slope, but none of the well-built houses had been dislodged, and the great buildings on this water-front were in good condition. Mr. Clatt was not visible, but left his cottage at Isabel's call, and gave them something more than his usual surly greeting.
