"He was locked up in that blasted diving dress!"

"Locked up?"...

"Sewed up—sacked up," said Peters heavily. "Did you ever see the damn' stuff? He calls it canvas, which it ain't, but tanned twill—two-ply—with rubber between. He can't tear his way out with a stick, he says. And small wonder. Talk about strait-jackets!"

"But—but why doesn't he take off the helmet?"

Peters stared unseeing at the packet in his hand, and his face was saturnine.

"By Joe, what a mess!" he murmured. "What a beau-ti-ful mess! Look here—d'y' know a diver's outfit? First he wears a solid breastplate—see?—that sets about his shoulders. Then the helmet fits on that with segmental neck rings and screws hard down with a quarter turn to a catch. Aye, there's a catch to snap it home.... And where is that catch? Why at the back! No diver was ever intended to take off his own helmet!"

We could only blink at him dumbly.

"Albro couldn't reach it. Of course if he should manage to rip away the cloth from the eyelets he'd be all right—he'd simply shift the whole upper works. But them eyelets, now, they lock down all around through a vulcanized collar. He couldn't reach more'n two of them either."

"There's the glass—"

Peters offered the diary.
