THE FOREST FAMILIES Trees are as queer in picking out places to live and in their habits of growth as are the peoples of the various races which inhabit the world.

Some trees do best in the icy northland.

They become weak and die when brought to warm climates.

Others that are accustomed to tropical weather fail to make further growth when exposed to extreme cold.

The appearance of Jack Frost means death to most of the trees that come from near the equator.
