"By the mark six!" shouted the port leadsman, who was on the side nearest to the island of Santa Rosa.

This did not induce the pilot to take any further action, and the Teaser continued on her course at less than half speed. Christy looked at his watch by the light of the binnacle lamps. It was half-past eleven, and the Teaser appeared, as well as he could calculate it, with the necessary allowances, to have made at least sixteen knots on the run from the sound channel.

"And a quarter five!" cried the leadsman of the land side.

Christy spoke to Sampson through the tube, and the result was a further reduction in the speed of the steamer, Beeks, who was at one side of the wheel while the lieutenant was at the other, seemed to be a little nervous as the depth diminished; and if he had spoken his thought, he would have expressed his surprise that his superior officer was running the steamer so near the shore, with the apparent intention of going still nearer.

"Mark under water three!" yelled the leadsman on the port side, while the one on the starboard gave "By the mark four."

"Shoaling fast," said Beeks.

"Yes; but as expected," replied Christy.

"Steamer, ahoy!" shouted a voice on the port side.

"On shore!" replied Christy promptly.

"What steamer is that?" demanded the shore speaker.
