Lesson 29.

1.  Look at a globe.  Find a line running round the globe at the thickest part.  This is called the Equator, because it divides the earth into two equal parts.  The hottest parts of the earth lie round about the Equator.  The distance round the earth at the Equator is 25,000 miles.  A railway train, running 50 miles an hour, and never stopping, would require nearly three weeks for the journey.  Find out whether father’s voyage was longer or shorter than this.

2.  Measure with a band of paper the distance on the globe from the Equator on one side to the Equator on the other.  Find half this distance and mark it on the globe.  Then mark the same distance on the other side of the Equator.  The points which you have marked are called the Poles.  One is the North Pole; the other is the South Pole.
