“Used an ammonia squirt-gun on each one,” said Ned.

He showed the boys two affairs that looked like small revolvers, only the ammunition was liquid spirits of ammonia, quite strong, contained in a rubber bulb in the handle. By pressing the bulb a fine stream of ammonia could be shot for quite a distance.

“I saw ’em advertised in a magazine,” said Ned. “They were just the things for vicious dogs and men, it said, for they blind a person temporarily and make his face smart like sixty, but no permanent injury is done. I had ’em in my valise and I just happened to think of them when those chaps held us up.”

“Lucky you did,” commented Jerry. “I thought we were surely going to be robbed.”

“I guess they thought they were killed when they felt that ammonia,” said Bob. “Ned, you’re all right, that’s what you are!” he finished, heartily.

“I guess we’d better move along, or Mr. Wakefield may be worried about us,” suggested Jerry.

So Bob threw the gear into place and the machine moved away. No further sign of the tramps was seen, and the boys reached Norwich without further incident. They found the hotel Mr. Wakefield had arranged to meet them at, and soon were eating a good supper. The adventure with the tramps was related, and Mr. Wakefield congratulated the boys on their pluck.

An early start was had next morning and good progress was made, so that by noon the travelers were in Waterbury, Conn., where dinner was eaten. Mr. Wakefield said that by swift traveling New York could be reached late that night, but he did not advise it. Instead, the night was spent in Danbury.

By noon the next day more than half the distance between their last stopping place and New York had been covered, and late that afternoon found the two autos speeding down Riverside Drive, leading to the metropolis. Not an accident had occurred since the hold-up by the tramps and the blowing out of the tire on the boys’ auto, and each one was congratulating himself that the trip was being made under the best of luck.

The travelers were about opposite Grant’s tomb, and were moving along slowly, when suddenly, with a noise like a shot, one of Mr. Wakefield’s tires burst. A young woman, driving a spirited horse, was passing his auto at the time, and the animal, taking fright, took the bit in his teeth and bolted.
