`` Lad , when you gets lonesome to talk come down to the engine room when it 's my watch on , '' Barney invited heartily . `` I 'll show you the big engines , and we 'll chum up a bit . I 'm off watch now , but I 'll be on at eight bells . That 's four o'clock , land reckoning . I 'll come and get you , b ` y , and show you the way . '' `` Thank you ! Thank you ever so much ! ''
