“By Jove, that’s good news!” cried Maurice, as the Demarch handed the key to his daughter. “Now we will know all about the new yacht, uncle, and if Melnos is taken, we can go to Syra, and escape on board of her.”

“Melnos won’t be taken,” said Justinian with a frown. “I am quite astonished at your suggesting such a thing, Maurice. Besides, the yacht is going to Athens.”

“Yes, but Crispin sent a letter to the telegraph office there, telling them to wire to the agents that the yacht was to stop at Syra.”

“Humph! well, that is not bad news. As you say, it is as well to be prepared for emergencies. Here is the key, Helena. Where is Crispin?”

“Waiting at the tunnel entrance!” replied Helena brightly, and went away with the key of the island, guarded by Dick and Zoe.

There was every sign that these two were following in the footsteps of their master and mistress, for as Zoe, tutored by Helena, could speak English very well, there was no obstacle to Dick’s wooing. The bos’n was a handsome young fellow, with a masterful manner about him, which the Greek maiden found very pleasant, so she was not at all indisposed to yield to his solicitations, and become Mrs. Dick, the more so, as she thought this marriage would not part her from Helena, whom she loved dearly. Her early flame, Gurt, had quite vacated the field in favor of his handsome young rival, and now took a paternal interest in the match. As yet, Zoe, with innate coquetry, had not given Dick a direct answer, but there was little doubt, in the end, she would accept this assiduous lover who worshipped her very shadow.

While the three had departed to take Crispin the key of the gate, Justinian continued examining the electric apparatus, and questioning Alexandros concerning the mode of working.

“The moon is not up till late to-night,” said the Demarch, looking at the sky, “so in the darkness we will be able to test it splendidly. Are the lights at the tunnel and the western pass in order, Alexandros?” he added in Greek.

“Yes, Kyrion. I attended to them to-day, myself.”

“And the engine?”
