“I know. I tried to shut it, but the wood must have swollen in the water. Yet the more it has swollen, the better it ought to keep out the light, oughtn’t it?”

“I’m afraid there isn’t a dog’s chance,” he murmured, as he handled the camera again. Yet it was not of the folding-bellows variety, but was one of the earlier and stronger models in box form, and it had come through its ordeal wonderfully on the whole.
