"It's nasty weather like this here that turns heads gray before their time," he said, with a nod toward the pilot-house.
"I had not thought there was any particular strain," I answered. "It seems as simple as A, B, C. They know the direction by compass, the distance, and the speed. I should not call it anything more than mathematical certainty."
"Strain!" he snorted. "Simple as A, B, C! Mathematical certainty!"
He seemed to brace himself up and lean backward against the air as he stared at me. "How about this here tide that's rushin' out through the Golden Gate?" he demanded, or bellowed, rather. "How fast is she ebbin'? What's the drift, eh? Listen to that, will you? A bell-buoy, and we're a-top of it! See 'em alterin' the course!"
From out of the fog came the mournful tolling of a bell, and I could see the pilot turning the wheel with great rapidity. The bell, which had seemed straight ahead, was now sounding from the side. Our own whistle was blowing hoarsely, and from time to time the sound of other whistles came to us from out of the fog.
"That's a ferry-boat of some sort," the newcomer said, indicating a whistle off to the right. "And there! D'ye hear that? Blown by mouth. Some scow schooner, most likely. Better watch out, Mr. Schooner-man. Ah, I thought so. Now hell's a-poppin' for somebody!"
The unseen ferry-boat was blowing blast after blast, and the mouth-blown horn was tooting in terror-stricken fashion.
"And now they're payin' their respects to each other and tryin' to get clear," the red-faced man went on, as the hurried whistling ceased.
