The Robin appeared to understand the matter thoroughly. It kept going from tree to tree， always a few yards ahead of them， but always so near that they could easily follow it. In this way it led them on， slightly downhill. Wherever the Robin alighted a little shower of snow would fall off the branch. Presently the clouds parted overhead and the winter sun came out and the snow all around them grew dazzlingly bright. They had been travelling in this way for about half an hour， with the two girls in front， when Edmund said to Peter， “if you’re not still too high and mighty to talk to me， I‘ve something to say which you’d better listen to.”
“What is it？” asked Peter.
“Hush！ Not so loud，” said Edmund； “there‘s no good frightening the girls. But have you realized what we’re doing？”
“What？” said Peter， lowering his voice to a whisper. “We‘re following a guide we know nothing about. Howdo we know which side that bird is on？ Why shouldn’t it beleading us into a trap？”
“That‘s a nasty idea. Still.a robin， you know. They’re good birds in all the stories I‘ve ever read. I’m sure a robin wouldn‘t be on the wrong side.”
