"That's the 'Massapequa,'" he declared, laying down the glass.
"There, they've picked us up," cried Jack, as the light passed over the top of the conning tower.
"They won't be sure after just that brief flash at us," rejoined
Ennerling. "Drop out of sight."
Jack let the "Pollard" drop at a semi-dive. Just as they had barely gone under there was a steadier flash of light on the water in front of them. Jack chuckled.
"Quick work," nodded Ennerling, approvingly. "The lookout on the gunboat thought they saw something here on the water, and swung the ray back to find out what it was. Now, they've doubtless concluded that they were fooled by a shadow."
"The next time we come up we'll have passed the 'Massapequa' and be astern of her," predicted Jack.
"Good enough, if you can calculate correctly the distance. The gunboat, of course, has no searchlight aft."
For some minutes the "Pollard" ran under water.
"I'm sure we're a little astern, now," said Captain Jack. "I'll take a lift up into the atmosphere."
With that the "Pollard," which had been running not more than five feet below the surface of the water, rose gently.
