Thinking-cap

Now suppose they put on their "thinking-caps" a moment or two, and consider what is going on in the great world around them. [...] Before you pull off your "thinking-cap" cast a look around your own country—free, prosperous, powerful, independent; yet how full of wickedness, and how unmindful of its obligation to the God of nations!

The story you shall have, then, just as well as I can tell it: and you must put on your thinking-caps, so as to remember all you can of it; and be sure to ask questions about what you don't understand.

"The old fellow needs a wife!" said the Great Spirit taking off his thinking-cap.
