“No, it doesn’t seem to be,” replied Nyoda. “I looked at it from the outside.”

“Then what can it be for?” repeated Sahwah.

“I don’t know, I can’t imagine,” replied Nyoda. A note of wonder was creeping into her voice. “To tell the truth,” she said, “I never thought anything about it. I noticed that there was an iron shutter over that window when we first came here, but I was too much taken up with Sherry’s going away then even to wonder about it. The room has been closed up ever since and I had forgotten all about it. It does seem a queer thing, now that you call my attention to it. But Uncle Jasper did so many eccentric things, I’m not surprised at anything he might have done. We’ll take the shutter off in the morning and see if we can discover any reason for having it there.

“Now, aren’t you going to hunt for the secret passage after I’ve opened the door for you?” she said quizzically. “There’s still an hour or so before bedtime; long enough for all of you to complete the destruction of your knuckles.”

Again the house resounded with the tapping of knuckles against hardwood paneling, until it sounded as though an army of giant woodpeckers were at work, but the eager searchers continued to bruise their long suffering knuckles in vain. The paneling in Uncle Jasper’s study was as solid as the Great Wall of China.

CHAPTER IV
AN INTERVIEW WITH HERCULES

Among the furniture stored in the study was one piece which Nyoda had pounced upon with an exclamation of joy the night before when she opened the room to please the Winnebagos. That was an invalid’s wheel chair.

“Just the thing for Sylvia!” she exclaimed delightedly. “She can get around the house by herself in this. It’s a good thing you got curious about this room, Sahwah dear; I’m afraid I wouldn’t have thought of opening it until spring. I remember now, Uncle Jasper had a paralytic stroke some months before he died which left him lame, and he went about in a wheel chair during his last days. This certainly comes in handy now.”

The morning after Sahwah had discovered the iron shutter Sylvia was set in the wheel chair and rolled into the study, and the rest came flocking up to watch Sherry and the boys remove the shutter. It was no easy job, taking that shutter off, for the screws had rusted in so that it was almost impossible to turn them. Nyoda gave an exclamation of dismay at the holes left in the mahogany casement. The Winnebagos were too much absorbed in the window which was revealed by the removal of the shutter to pay any attention to the damaged casement. Unlike the other windows in the room, which were of clear glass, this one was composed of tiny leaded panes in colors. It was so dirty on the outside that it was impossible to see what it really was like. Sahwah hastened out and got cleaning rags and washed it inside and out, standing on the roof of the side porch to get at it on the outside, because it did not open. When it was clean, and the bright sun shone through it, the beauty of the window struck them dumb.

The leaded panes were wrought into a design of climbing roses, growing over a little arched gateway, the rich red and green tints of the flowers and leaves glowing splendid in the mellow light that streamed through it.
