'' Captain Scraggs read the log and reported the mileage to Mr. Gibney , who figured with the stub of a pencil on the pilot house wall , wagged his head , and appeared satisfied . `` Better go for 'd , '' he ordered , `` an ' help The Squarehead on the lookout . At eight o'clock we ought to be right under the lee o ' Point San Pedro ; when I whistle we ought to catch the echo thrown back by the cliff . Listen for it . '' Promptly at eight o'clock , Mr. McGuffey was horrified to see his steam gauge drop half a pound as the _ Maggie 's _ siren sounded . Mr. Gibney stuck his ingenious head out of the pilot house and listened , but no answering echo reached his ears .
