CHAPTER V 

AT NIAGARA FALLS 

"See here, I want you to let me alone!" stormed Nat Poole, and he tried to jerk himself free. 

"Listen, Nat," said Dave, sternly. "If you make a noise it will be the worse for you, for it will bring the others here, and then we'll tell about what you tried to do. Maybe Mrs. Wadsworth will call an officer, and anyway all the girls and the boys will be down on you. Now, if you want Phil and me to keep this a secret, you've got to come along with us." 

"Where to?" grumbled Nat, doggedly. 

"You'll soon see," returned Dave, briefly, and with a wink at his chum. 

Somewhat against his will, Nat walked toward the end of the garden. He wished to escape from Mrs. Wadsworth and the others, but he was afraid Dave and Phil contemplated doing something disagreeable to him. Maybe they would give him a sound thrashing. 

"Don't you touch me--don't you dare!" he cried, when the barn was readied. "Remember, my father can have you locked up, Dave Porter!" 

"Well, don't forget what Professor Potts can do to you, Nat," answered Dave. 

"What are you going to do?" asked Phil, in an aside to his chum. 

Dave was trying to think. He had been half of a mind to lock Nat in the harness closet until the party was over--thus preventing him from making more trouble. Now, however, as he heard a locomotive whistle, a new thought struck him. 
Did Nat do something somewhat against his will?
he tried to jerk himself free.
