“They’re no good,” replied Jimmie, “but we’ve got plenty at the camp. Ben wanted to keep them stored in the boxes under the seats, but I sneaked some out when we landed in the green bowl and put them away by the pile of tenting. Good thing I did, too.”

“If you hadn’t, they would be on board the Louise right now,” Kit said, “and we would be without any.”

“You chase back to camp and bring the plugs,” Jimmie directed, “and I’ll stay here and look the machine over once more. Hurry back, for we want to get up in the air in time to see the lights of the Louise.”

“They must be pretty far away by this time,” suggested Kit.

“Yes, we can go up far enough to see for fifty miles on each side!” Jimmie said. “They can’t be fifty miles away by this time.”

Kit hastened away to the camp, and soon returned with the spark plugs. In a very short time the machine was pulled out of the little depression in which the wheels lay and drawn down to a level which would permit of a flight. It was by no means as large as either the Louise or the Bertha but a strong aeroplane for all that.

“Now,” Jimmie suggested. “We ought to go and see if there’s anything left to eat here, and take it away with us if there is.”

“You can’t get the smell of that bear steak out of your nostrils, can you?” laughed Kit.

“But just think who gave it to us?” Jimmie grinned.

After packing away provisions enough for a meal or two the boys put the machine into the air and lifted slowly out of the bowl.
