"How are you fixed for electrolysis?" he asked, as he handed King the list.
"Guess we can fix you up all right. We've got a good storage battery and two or three glass tanks and considerable platinum. Now we'll go up and see if breakfast is ready," he said, putting the pager in his pocket.
CHAPTER X.
THE DETECTIVE ARRIVES.
"But, father, isn't there something we can do?" asked Jack, for about the tenth time that day. It was about three o'clock in the afternoon of the day following Bob's disappearance. They had waited in vain for any news of the lost boy and at about eight-thirty o'clock, Mr. Golden had got into communication, by telephone, with a well-known detective agency in Boston and they had promised to have one of their best men there on the four-forty train.
"Yes, I guess we can do something now. We'll run across in the Sprite, and catch the four o'clock trolley to town, which will get us there in time to meet that detective, Mr. Sharp."
Glad of anything which promised action, Jack grabbed his cap and started for the boathouse. It had been a terrible day to him, for he was lost without Bob, and the thought that he might never see him again nearly drove him frantic. He and his father were soon in the Sprite speeding across the lake, and as they reached the wharf in front of the hotel, they saw Fred and Will Jenkins just getting into their boat.
