"I am sure the captain and the first lieutenant have no suspicion that I am not what I seem to be.

The executive officer put me through a full examination, especially in regard to Cherryfield, where I told him I used to live.

I came off with flying colors, and I am certain that I am all right now." Dave knew nothing about the examination to which Mr.Flint had subjected the deaf mute.

It is evident that Mulgrum took an entirely different view of the result of the test from that taken by the examiner and the captain; but both of the latter had taken extreme pains to conceal their opinion from the subject of the test.
"I think we had better not say anything more to-night, and you have been on the bridge long enough," said Mr.Lillyworth, walking to the windward end of the bridge, and peering out into the gloom of the night.
He had hardly looked in the direction of the deaf mute while he was on the bridge, but had busied himself with the lashing of the screen, and done everything he could to make it appear that he was not talking to his companion.

Mulgrum, overhauling the screen as he proceeded, made his way to the steps by the side of the foremast.
