The lightning and the thunder were both dying now, but the rain came in a steady and mighty sweep.

"Robert," said Willet in a whimsical tone, "one of the first things I tried to teach you when you were a little boy was always to be calm, and under no circumstances to let your calm be broken up when there was nothing to break it up.

Now, we've every reason to be calm.

We've got a good home here, and the storm can't touch us." "I was already calm, Dave," replied Robert lightly.
