On this subject the Boston Journal makes the following interesting remarks:
It seems to have been ascertained historically, that in countries like France, Italy, Spain, and Palestine, which have been largely cleared of woods, the annual fall of rain is less now than it was formerly. On the other hand, extensive tree planting in Egypt and Scotland have been followed by more rain yearly than was previously known in those sections.
These are certainly curious results if truly reported. They are attributed in part to the attraction of upright masses of trees for the rain clouds and to other influences not well understood. But however this may be, it is clear to the common sense of every observing man, that a country abounding in woods will retain its average fall of rain longer, and turn it to better account, than a country that is bare. In the latter the wind has a clean sweep over the whole surface, drying up and baking the soil, exhausting the springs and water courses. When the snow melts in the spring , or heavy rains fall, there is nothing to detain the water, but rushes off in sudden, destructive freshets, gullying the land and bearing away its richness.
