And that sentry-box effect was the pride of Danny's heart. Most of his spare time and all the money he could bone out of the commuters he spent in improvin' and decoratin' it. He'd cut a couple of round windows, like port-holes, and fitted 'em with swingin' sashes. Then he'd tacked on some flower-boxes underneath and filled 'em with geraniums.

When he wasn't waterin' his flowers or coaxin' along his little grass-plot or addin' another shelf inside, he was paintin' the outside. Danny's idea of a swell color scheme seemed to be to get on as many different shades as possible. The roof was red, the sides a bright blue. But where he spread himself was on the trim. All you had to do to get on the right side of Danny was to lug him out a half-pound can of paint different from any he'd applied so far. He'd use it somehow.

So the window-sashes was picked out in yellow, the side battens loomed up prominent as black lines, and the door-panels was a pale pink. Nearly all the commuters had been touched by Danny for something or other that could be added to the shack. Only a week or so before, I'd got in strong with him by contributin' a new padlock for the door—a vivid red one, like they have on the village jail in vaudeville plays.

And it struck me now that if I had the key to that little box of Danny's it would make a perfectly good listenin'-post for any midnight sleuthin' I had to do. Most likely he was up dosin' himself or bathin' his joints.

Well, he was. He didn't seem any too enthusiastic about lettin' me have the key, though.

"I dunno," says he. "'Tis railroad property, y' understand, and I'd be afther riskin' me job if any thin' should——"

"I know, Danny," says I. "But you tell 'em it was commandeered by the U. S. Army, which is me; and if that don't square you I'll have Mr. Baker come on and tell the section boss where he gets off."

"Verra well," says Danny. And in less than five minutes more I'm down there at the crossin', all snug and cozy, peekin' out of them round windows into No Man's Land.

For a while it was kind of excitin'; but after that it got sort of monotonous. There was about half of an old moon in the sky, and only a few clouds, so you could see fairly well—if there'd been anything to see. But nothing seemed to be stirrin', up or down the road.

What a nut that Norton Plummer was, anyway, feedin' me up with his wild tales in the middle of the night! And why didn't he show up? Finally I got restless, and walked out where I could rubber up the trolley track. No sign or sound of a car. Then I looks at my watch again, and figures out it ain't due for twenty minutes or so. Next I strolls across the railroad to look for Plummer. And, just as I'm passin' a big maple tree, out steps this huge party with the whiskers. I nearly jumped out of my puttees.
