"Hello, Ned," came a ringing greeting from Alan as he ran forward. "They were afraid you wouldn't get here. But I knew you would. It's only a minute or two. Hurry."

"Four," said the new arrival cheerfully and confidently.

He gave his left hand to Alan and a better welcome in a cheery word of greeting, but his right hand did not leave the truck. Nor did his eyes leave it except for a moment.

"And the Major?" asked the new arrival as the truck rumbled on.

"Waiting to bid us good-bye."

"Everything aboard and shipshape?"

"Everything but this," and Alan glanced at the black case on the truck.

"I've carried it a thousand miles like a baby," laughed Ned. "Rode with it all the way in the express car."

"Then you didn't sleep last night?"

Ned laughed. "It was too interesting," he answered, "and I can sleep to-night. But I'm glad it's here with no one killed and not a drop spilled."
