But poor Andy still lay in a stupor and he did not recover until several hours after.

It was no mean task to repair all the damage done to the intricate machinery of the Holland XI. and for two days every man on board was kept busy.

Fortunately, however, nothing had been destroyed but the burnt-out switchboard, and luckily there was a duplicate switchboard in the storeroom. Oscar himself put this into place and when tried it worked perfectly.

"Now I reckon we are all right once more," said the young commander, after a test had been made of all the working parts of the submarine boat.

Yet to make certain that he was ready for active service, once again he ran the Holland XI. out into the ocean and made her go through all the movements of blowing up a warship.

Then the course was changed for Cape Nome and soon they were but a few miles from that port.

An American warship was sighted, but Oscar got no opportunity to hail her, for she was steaming along at full speed.

"Looks as if she was running from something," said Andy.

The American warship had scarcely sailed out of sight to the southeast than the lookout announced a strange craft coming up from the southwest.

The new Holland was sunk almost to the level of the ocean, so that only the trap deck was above the water.
