The lads saw Harry bending over the form of their missing chum. Jimmie lay in a heap, blocking the passageway.

Fearful that their first suspicions had been correct, the boys scarcely dared investigate. Jack began growling out uncomplimentary remarks concerning Mackinder. Ned quickly forced his way to Harry’s side.

“Here, let me see him!” Ned cried, throwing the flame of his searchlight on the recumbent form. “Why, he’s all huddled up!”

“All in a bunch!” agreed Harry. “I wonder if he’s hurt!”

“Roll him over,” directed Ned. “Let’s get him out of here!”

“Why, he’s tied!” cried Harry, in a startled voice.

“Tied?” questioned Jack, pushing forward. “Who tied him?”

“And gagged!” went on Harry, his voice vibrating with indignation. “Mackinder will pay for this!” the lad continued. “We’ll get him!”

Without the loss of a moment Harry was swiftly relieving Jimmie of the object which prevented speech. A small block of wood had been forced between Jimmie’s teeth. This had been secured in place by tying a handkerchief over his face. The gag had been extremely effective, even though it was uncomfortable and crude.

As the gag was removed Jimmie wagged his jaw a few times to relieve the strained muscles. He nodded his appreciation.
