It will seem tough, though, to be so near Darry and Danny Grin and not have even a wave of the hand from them." "What part of the ocean are we in ?" Greg called up to the obliging bridge officer.
"On the surface, sir," came the dry reply.

"On the surface---just where, in latitude and longitude ?" Holmes insisted.
But the ship's officer smiled and shook his head.
"I'm not permitted to tell that, sir.

Dick named the two destroyers commanded by Lieutenant-Commander Dave Darrin and Lieutenant-Commander Dan Dalzell and asked the bridge officer if he could point them out.

Not that any periscopes were now visible, however, for these had been instantly withdrawn under the surface.
