ABSTRACT

Temperature.—To become convinced that the destruction of the forests would increase the temperature of the ground in summer one has only to ride in an open conveyance, on a hot day, across a prairie or cleared country, and then enter the depths of a dense forest. The change is at once apparent from the burning heat of the sun we pass to the cool shade of the trees, and find a contrast so great that it must have been observed by every one; it is the difference between sunshine and shade; and is so obvious that … clearing the land of trees increases the temperature of the ground in the summer.
