"But do you not think," inquired Mrs. Weldon, "that you have made some error in your reckoning? Is your speed really what you have supposed?"
"Impossible, madam," replied Dick, with an air of dignity, "impossible that I should have fallen into error. The log has been consulted, without fail, every half-hour. I am about to have it lowered now, and I will undertake to show you that we are at this present moment making ten miles an hour, which would give considerably over 200 miles a day."
He then called out to Tom,-
"Tom, lower the log!"
The old man was quite accustomed to the duty. The log was fastened to the line and thrown overboard. It ran out regularly for about five-and-twenty fathoms, when all at once the line slackened in Tom's hand.
"It is broken!" cried Tom; "the cord is broken!"
"Broken?" exclaimed Dick: "good heavens! we have lost the log!"
It was too true. The log was gone.
Tom drew in the rope. Dick took it up and examined it. It had not broken at its point of union with the log; it had given way in the middle, at a place where the strands in some unaccountable way had worn strangely thin.
Dick's agony of mind, in spite of his effort to be calm, was intensely great. A suspicion of foul play involuntarily occurred to him. He knew that the rope had been of first-rate make; he knew that it had been quite sound when used before; but he could prove nothing; he could only mourn over the loss which committed him to the sole remaining compass as his only guide.
