"Gus!" he called, throwing open a window. "Come in here!"
The tramp soon stood before them.
"Geel Dis is a swell joint," were the tramp's first words as with apparent awkwardness he entered the car.
Ned acted as spokesman.
"You say you've promised Buck to go with him without knowing where you are going?"
"Dat's about de cheese."
"Well, we are willing. But I may as well tell you that this is a secret expedition. If you go you must promise that you will not tell anyone what you see or hear."
The tramp's face suddenly took on a peculiar look, but it was gone as quickly.
"I gives me woid. I won't open me trap to no one."
"Meaning you won't say anything about it?" smiled Ned inquiringly.
