"I thought so, too, Tom, but, bless my batteries, my doctor insisted that I must get out in the open air. I'm too stout to walk, and I can't run. The only solution was in an automobile, for I never would dream of a motor-cycle. I wonder that one of mine hasn't run away with you and killed you. But there! My automobile is nearly as bad. We went along very nicely yesterday, and now, just when I have a party of friends out, something goes wrong. Bless my liver! I do seem to have the worst luck!" Tom lost no time in looking for the trouble. He found it in the ignition, and soon had it fixed. Then a sort of council of war was held. "Do you think those scoundrels are there yet?" asked Mr. Damon. "I hope so," answered Tom. "So do I," went on the odd character. "Bless my soul, but I want a chance to pummel them. Come, gentlemen, let's be moving. Will you ride with us, Tom Swift, or on that dangerous motor-cycle?" "I think I'll stick to my machine, Mr. Damon. I can easily keep up with you." "Very well. Then we'll get along. We'll proceed until we get close to the old mansion, and then some of us will go down to the lake shore, and the rest of us will surround the house. We'll catch the villains red-handed, and I hope we bag that tramp among them." "I hardly think he is there," said Tom. In a short time the auto and the motor-cycle had carried the respective riders to the road through the woods. There the machines were left, and the party proceeded on foot. Tom had a revolver with him, and one member of Mr. Damon's party also had a small one, more to scare dogs than for any other purpose. Tom gave his weapon to one of the men, and cut a stout stick for himself, an example followed by those who had no firearms. "A club for mine!" exclaimed Mr. Damon. "The less I have to do with machinery the better I like it. Now, Tom Swift is just the other way around," he explained to his friends. Cautiously they approached the house, and when within seeing distance of it they paused for a consultation. There seemed to be no one stirring about the old mansion, and Tom was fearful lest the men had left. But this could not be determined until they came closer. Two of Mr. Damon's friends elected to go down to the shore of the lake and prevent any escape in that direction, while the others, including Tom, were to approach from the wood side. When the two who were to form the water attacking party were ready, one of them was to fire his revolver as a signal. Then Tom, Mr. Damon and the others would rush in. The young inventor, Mr. Damon, and his friend, whom he addressed as Mr. Benson, went as close to the house as they considered prudent. Then, screening themselves in the bushes, they waited. They conversed in whispers, Tom giving more details of his experience with the patent thieves. Suddenly the silence of the woods was broken by some one advancing through the underbrush.
