"Not that I know of, Ned," was Jimmie's sober reply. "We just stumbled onto you as you were tracking something in the woods."
"Oh, that reminds me," Ned said, halting. "We were on the track of some fellow who visited our position and took out the spark plugs from our engines. We were following his tracks in the woods when you came."
"What sort of a guy was he?" asked Jimmie, intensely interested.
"I don't know," answered Ned. "We haven't seen him yet."
"Didn't he leave any signs at all?" went on Jimmie. "Did he come and go in an airship, or did he have wings and fly through the air?"
"Neither," declared Ned. "He left some pretty fair tracks."
"Then we'll get him!" asserted Jimmie, positively. "He can't get away. Once we get on his trail he might as well quit!"
"Good boy, Jimmie!" laughed Ned. "You're a sight for sore eyes. And," he went on, "it's a pleasure to have your optimism to help."
"Thanks!" drily responded the Wolf. "Where are his tracks?"
"Right around here at the front of the machine near the engine."
