"Here's the hole where Carl dropped out the paper scraps," Matt called, from inside the wagon.
"And here's something else, pard!" yelled McGlory.
Matt came out of the wagon and found his cowboy chum calling Burton's attention to marks in the road.
"What do you make of it, Joe?" asked Matt, coming closer.
"Well," answered McGlory, reading the "signs," "a one-horse buggy with rubber tires stopped here, alongside the monkey wagon. Look how the road's tramped up, ahead there. The horse was restive during the halt, and did some pawing."
"Great guns!" murmured Burton. "My runabout!"
"I think it's pretty clear now," observed Matt. "Aurung Zeeb and Haidee didn't get away at the same time Ben Ali and Carl did, or else they took a different course. Anyhow, they came up with the wagon. The runabout's faster, so the whole party went on with it."
"They might get three people into the runabout, by crowding," said Burton, "but they never could get four people into it."
"That's why the horse was taken from the monkey wagon," went on Matt. "Aurung Zeeb or Ben Ali must have ridden the animal."
