All parts of the earth do not have the same seasons. If we should travel north, we should find the climate growing colder and colder. After a long time, we should come to a region of intense cold. The ground would be covered with ice and snow all the year through, both winter and summer. This most northern part of the earth is called the North Pole. The region around it is the North Frigid Zone. There is a South Pole and a South Frigid Zone as cold as the northern one. You can see where they are on the diagram.

If we start from the North Pole and take a trip south we find it constantly growing warmer. At last we come to a place where it is extremely warm in both summer and winter. That region is called the Torrid Zone because 'torrid' means 'hot.' This hot zone extends right around the middle part of the earth. The very hottest part through the middle is the Equator.

The United States is in a zone between the very cold region, or Frigid Zone, and the very warm region, or Torrid Zone. This zone is called the North Temperate Zone. This area has spring, summer, autumn and winter. The weather is seldom so cold as in the Frigid Zones, nor so warm as in the Torrid Zone. The spring and autumn are mild or temperate.

Find the South Temperate Zone. Its climate is just like ours. What seasons do they have there? What zone lies north of it and which south of it?

Notebook Work: Label the top of your notebook page with "LESSON 26." Copy the diagram of the zones and the Equator in your notebook. Label the map with the directions of north, east, south, and west.
