“You may depend upon that,” answered Tom.
“I conclude that you can tell whereabouts we now are?” said the doctor.
“Not unless I can learn at what hour sail was made and we began to stand on our present course,” was the reply.
When Tom inquired of the carpenter, he received an evasive answer, and on going forward to learn from Jerry, Tim, or Pat, they all said that they had gone below at night, and had not been roused up. Some of the crew replied that it was in the first watch, others that it was in the middle watch.
“At all events, I hope to ascertain our latitude if the weather clears, and perhaps we may get an observation in the afternoon, or a lunar at night,” said Tom. “But a good look-out must be kept ahead, for I know that there are numerous small islands and reefs, one of which may bring us up if we are not careful.”
The doctor assisted the midshipmen to search for a sextant and nautical almanack, but, to their surprise, neither were to be found. “The chronometer was,” the doctor said, “he knew, in the captain’s cabin;” and they at last began to suspect that the boatswain had managed to get hold of the mate’s as well as the captain’s sextant and charts, and had shut them up in the cabin he had appropriated. What his object was in so doing it was difficult to say, unless he thought that he should keep the midshipmen more in his power by preventing them from knowing whereabouts they were.
Just before breakfast the boatswain came out of his cabin, carefully locking the door behind him. After remaining on deck some time, he returned and took his seat without uttering a word either to the surgeon or to the midshipmen, although he swore away at Peter for not being quick enough in bringing him what he asked for. Tom took no notice of this, but after waiting some time, said in his usual polite way—
“I should be much obliged to you, Mr Betts, if you can supply me with a sextant, and the use of the chronometer, as I should like to ascertain our position.”
“Then you won’t be obliged to me, for I don’t intend to let you have them,” answered the boatswain. “I can take care of this ship, and I won’t have any one interfering with me.”
“I do not wish to interfere,” said Tom. “I only desire to take an observation for my own satisfaction.”
