“What’s that?  The same men?  Broke in early this evening?  Oh, that’s too bad!  Of course, I’ll come at once.”

There followed more meaningless clicks, which Tom wished he could translate.  His father hung up the receiver, turned to him and exclaimed: 

“I’ve been robbed again!”

“Robbed again!  How, dad?”

“By that same rascally gang, Garret thinks.  This evening, when he and Mrs. Baggert were in the house the burglar alarm went off.  The indicator showed that the electrical shop had been entered, and the engineer hurried there.  He saw a light inside and the shadows of persons on the windows.  Before he could reach the shop, however, the thieves heard him coming and escaped.  Oh, Tom, I should never have come away!”

“But did they take anything, dad?  Perhaps Garret frightened them away before they had a chance to steal any of your things.  Did you ask him that?”

“I didn’t need to.  He said he made a hasty exanimation before he called me up, and he is sure a number of my electrical inventions are missing.  Some of them are devices I never have had patented, and if I lose them I will have no recovery.”

“But just what ones are they?  Perhaps we can send out a police alarm to-night.”

“Garret couldn’t tell that,” answered Mr. Swift as he paced to and fro in the hotel office.  “He doesn’t know all the tools and machinery I had in there.  But it is certain that some of my most valuable things have been taken.”

“Never mind.  Don’t worry, dad,” and Tom tried to speak soothingly, for he saw that his father was much excited.  “We may be able to get them back.  How does Garret know the same men who stole the turbine model broke in the shop this evening?”

“He saw them.  One was Happy Harry, he is positive.  The others he did not know, but he recognized the tramp from our description of him.”

“Then we must tell the police at once.”

“Yes, Tom, I wish you would telephone.  I’ll give you a description of the things.  No, I can’t do that either, for I don’t know what was stolen.  I must go home at once to find out.  It’s a good thing the motor-boat is here.  Come, let’s start at once.  What is my bill here?” and the inventor turned to the hotel proprietor, who had come into the office.  “I have suffered a severe loss and must leave at once.”

“I am very sorry, sir.  I’ll have it ready for you in a few minutes.”

“All right.  Tom, is your boat ready for a quick trip?”

“Yes, dad, but I don’t like to make it at night with three in.  Of course it might be perfectly safe, but there’s a risk, and I don’t like to take it.”

“Don’t worry about the risk on my account, Tom.  I’m not afraid.  I must get home and see of what I have been robbed.”

The young inventor was in a quandary.  He wanted to do as his father requested and to aid him all he could, yet he knew that an all-night trip in the boat down the lake would be dangerous, not only from the chance of running on an unknown shore or into a hidden rock, but because Mr. Swift was not physically fitted to stand the journey.
