On some other occasion, perhaps, Henry would have centred his attention on the views without, but now he was wholly occupied with the mysteries of this wonderful ship, so he paid slight heed to the wonderful sights in the Narrows, and gladly followed the ensign when the latter suggested that they step inside.
They entered the wheelhouse, a tiny room just behind the bridge, where a sailor stood at the wheel, steering the ship in accordance with the captain’s low-spoken orders. Immediately they passed through a door into the chart-room. This was somewhat larger than the wheelhouse, though tiny at best. On a large shelf or table lay a number of charts, some dividers, pencils, erasers, sliding rules, and some binoculars. In a rack on the wall were various code-books and books of instructions to navigators. Lieutenant Hill was erasing some lines from a chart. A moment later the captain stepped in. The two consulted the chart, and made some measurements with the sliding rule.
“Our course is east, three-quarters south,” said the lieutenant.
“Very good,” replied the captain. “Mark it on the chart.”
The lieutenant laid his rule along the course indicated, and drew a line on the chart, while the captain stepped into the wheel room.
“Keep her east, three-quarters south,” he said to the man at the wheel.
“Aye, aye, sir. East, three-quarters south,” answered the helmsman.
“We’re laying a course direct for Ambrose Lightship,” said the lieutenant to Henry. “After we reach that we will head directly for the location of the derelict.”
Presently, as he heard a thin, shrill whistle piping on deck, Henry turned to the ensign.
“What was that?” he inquired.
