A volley of shots was fired as an accompaniment to the startling yells. A moment later and a body of horsemen dashed into camp, which they had easily located by the smouldering camp-fire.
The Pony Rider Boys were out of their tents in a twinkling.
"Wow!" piped Stacy.
Bang! Bang!
Two bullets flicked the dirt up into his face. Bud Stevens and his companions were in a playful mood again.
"Hey, you! Better look out where you're shooting to!" warned Stacy.
Bud let go another volley.
"The Professor'll take you over his knee and chastise you with his shoe, if you don't watch sharp," said Stacy.
"Come out of that. Where's the kiddie? I want to see my kiddie!" laughed Bud Stevens.
By this time, with his companions, he had dismounted, turning the ponies loose to roam where they would. The whole camp, aroused by the shouting and shooting, had turned out after pulling on their trousers and shoes. Tom Parry, piling fresh fuel on the embers of the camp-fire, soon had the scene brightly lighted. There was no more sleep in camp that night. Professor Zepplin accepted the new disturbance with good grace.
