The eyes of the little inventor softened and into them crept a glint of pensiveness.

"Yes," he repeated, "we can deliver it up to Zenas Henry 'most anytime now." He paused. "Queer, ain't it, how kinder attached you get to anything you've fussed over so long? It gets to be 'most a part of you. You'll think it funny, I guess, but do you know I'll be sorter sorry to see this thing goin'."

It was the regret of the parent compelled to part from his child and with an effort at comfort Robert Morton said cheerfully:

"Oh, you'll be having a new scheme before long."

"Mebbe I will," Willie answered, brightening. "I never can tell when the sun rises in the mornin' what idee will kitch me before night. Still, I somehow feel there'll be no idee like this one. You know they say every artist creates one masterpiece," he smiled shyly. "This, I reckon, is my masterpiece."

"It is a bully one, anyhow!" ejaculated Bob. "Aren't you curious to hear what Zenas Henry will say when he sees it?"

"I am sorter itchin' to," admitted Willie in less meditative tone. "Only last night I was thinkin' after I got to bed how would be the best way of givin' it to him. I've sorter set my heart on springin' it on him as a surprise. What's your notion?"

"I think that would be a fine plan," replied Bob, eager to humor the gentle dreamer. "If we could get him and the captains out of the way, it would be good sport simply to fasten the attachment to the boat and wait and see what happened."

"Wouldn't that be the beateree!" chimed in Willie excitedly. His face glowed and he rubbed his hands with honest pleasure. "Wouldn't it, though? We could manage it, too, for Delight could arrange to get Zenas Henry an' the three captains out of the way. She's an almighty good one at keepin' a secret, as I reckon you've found out already."

He stole a sly glance at the young man at his elbow who flushed uncomfortably.
