A little instruction in the elements of chartography—a little practice in the use of the compass and the spirit level, a topographical map of the town common, an excursion with a road map—would have given me a fat round earth in place of my paper ghost; would have illumined the one dark alley in my school life.

I had frequent opportunities to observe these Eskimo ideas of chartography.

This topographical map, one yard high and divided into four parts, is a masterpiece of lunar chartography.
