“I've seen it too,” continued Donald, wondering whether an artist-proof and a waterproof had anything in common; “but the girls aren't often so handsome as that; but I'll tell you when they do look pretty as a picture: that's on a clear Sunday morning, just about midway in the service, when the sun comes streaming through one of the choir windows in a great white shaft of light, I think they call it. It just goes slanting across the benches, and then the girls it happens to strike, no matter how homely they are, really look just beautiful, with their white caps and kerchiefs all lighted up in the sunshine. I used to think they put the girls on that side to show them off, for the boys just look pretty much as boys always do.”
