"How near Gibbs Hill light can you go with safety in the darkness, Captain?" asked Mr. Gilfleur.

"I should not care to go nearer than ten miles; we could not be seen from the shore at that distance, but we might be seen by some small craft."

"That will do very well; and if you will make a point ten miles south-west of Gibbs Hills light, I shall be exactly suited," added the detective, as he made a small cross on the sketch near the place where he desired to embark in the boat.

The conference was finished, and the two passengers went on deck to inspect the craft which was to convey them to the islands. By order of the commander the carpenter had overhauled the boat and made such repairs as were needed. Every open seam had been calked, and a heavy coat of paint had been put upon it. The sailmaker had attended to the jib and mainsail, and everything was in excellent condition for the trip to the shore.

"Is this the same boat that you used when you were in the Bermudas, Mr. Gilfleur?" asked Christy, as they were examining the work which had been done on the craft, its spars and sails.

"Oh, no; it was six years ago that I spent the winter in the islands. I found this boat under a shed on a wharf in New York. It had been picked up near the Great Abaco in the Bahama Islands by a three-master, on her voyage from the West Indies," replied Mr. Gilfleur. "When I had formed my plan of operations in the vicinity of Nassau, in order to obtain the information the government desired, I bought this boat. When picked up, the boat had her spars, sails, oars, water-breakers, and other articles carefully stowed away on board of her; and it appeared as though she had broken adrift from her moorings, or had been carried away by a rising tide from some beach where those in charge of her had landed. I happened to find the captain of the vessel that brought the boat to New York; and he made me pay roundly for her, so that he got well rewarded for his trouble in picking it up."

The Chateaugay stood due south till six o'clock at little more than half speed, and when she came about her dead reckoning indicated that she was seventy-five miles to the south-west of Gibbs Hill light. The weather was very favorable for the proposed enterprise, with a moderate breeze from the west. Mr. Gilfleur did not wish to leave the ship till after midnight, for all he desired was to get inside the outer reefs before daylight. The speed of the ship was regulated to carry out this idea.

The light so frequently mentioned in the conference is three hundred and sixty-two feet above the sea level, for it is built on the highest point of land in the south of the Bermudas, and could be seen at a distance of thirty miles. At three bells in the first watch the light was reported by the lookout, and the speed was reduced somewhat.

About this time the detective came out of his stateroom, and entered that of Christy. He had smeared his face with a brownish tint, which made him look as though he had been long exposed to the sun of the tropics. He was dressed in a suit of coarse material, though it was not the garb of a sailor. He had used the scissors on his long black mustache, and given it a snarly and unkempt appearance. Christy would not have known him if he had met him on shore.

"You look like another man," said he, laughing.
