The little cutter was a fleet-winged craft, built for speed, and carrying greatly more horse power than ordinary steamers of twice her size. Her navigator and all her officers, indeed, knew every detail of the waters they were traversing, and so the lieutenant hoped that he might reach his destination in time to descend upon the smugglers before morning.

In this he was disappointed. Some accident to the cutter’s machinery compelled a delay of two or three hours in a narrow strait where, to add to the annoyance of delay, a swarm of sand flies descended upon the ship’s company. These are minute insects, so minute that no screen or netting, however finely woven, interferes in the least with their free passage in or out of any opening. Their bite or sting is even more painful than that of a mosquito, and they come in myriads.

Under the advice of the commanding officer the boys retreated to a closed cabin below and remained there until the ship was under way again—otherwise for two or three hours, during which they lolled about and managed to get some sleep in spite of their impatience over the delay and the otherwise excited condition of their minds.

By way of making themselves more comfortable, they all drew off their boots, but they could not be persuaded to go to the bunks assigned to their use, because the ship might start again at any moment and they were determined to be ready for that whenever it should occur.

Cal, as usual, was the most wakeful of the party, and at first he was disposed to talk, but his impulse in that way was promptly checked when Tom and Larry each threw a boot at him and Dick, half asleep, muttered:

“I second the motion.”

As a consequence of this drastic treatment Cal closed his lips and his eyes at the same moment and was presently breathing as only a sleeper does. The others, tired and worn out with an excitement that had by this time passed away, were soon in a profound slumber which lasted until the engines began to throb again and the ship to jar and tremble with the rapid revolutions of the screw.

The sun was well up by that time, and after going on deck, where a sailor doused bucketfuls of salt water over them as an eye-opener, they were invited to breakfast with the commanding officer.
