As for Bob he was far too eager to get into touch with O'Connel and the Siren to covet extra pay for rushing through the installment of the new service. A private signal had been agreed upon between him and his former associate and also an hour set when each day the operator aboard the yacht was to call him. O'Connel was to allow seven days for the work at Surfside to be finished and then his messages were to begin and both Mr. Crowninshield and his alert employee meant to be ready for him.

Hence Bob whipped on his helpers, using every ray of daylight that could be turned to the purpose and much of the night. Even after everything was placed and connected up there would yet remain a great deal of testing out and tinkering before the set would be in perfect working condition and it was for this delay he was preparing.

Much to his surprise, however, the parts went together with astonishingly little trouble. They had been well made and fitted perfectly. Everything needed was at hand and in consequence there was no sending to the city for materials and waiting until they could be shipped. Therefore as the allotted time sped by the job that accompanied it moved rapidly to its end.

"We are going to make it, sir," ejaculated Bob with shining eyes, beaming enthusiastically on the master of the estate. "She will be all set up and working by Saturday. That is the day O'Connel was to make his first try to get into communication with us. I can hardly wait to hear what he has to say."

"I am pretty anxious to know myself," returned the elder man. "If he can get a message through we should then find out where the yacht is and whether Lola is aboard her."

"I'm crazy to learn what has become of the villains who pinched the dog," added Bob. "Do you take it they are still cruising with the boat?"

"Oh, they must have been paid off and landed somewhere," was the answer. "There would be no sense in detaining the thieves on the ship until now. It would only mean paying them and having them to feed; besides one does not care to make two rascals members of a house party."

"You think they have escaped us then."

"If by escaping you mean getting to the city yes," nodded Mr. Crowninshield. "But I do not feel at all sure with Dacie and Lyman on their track that they will be entirely safe and unmolested in town. Those detectives are like bloodhounds and will run them down no matter where they may be hiding. The mere fact that they have got to New York or Boston will not be much protection."

"You intend to get them then as well as to recover Lola."
