Umbrageous forests are especially favorable to our existence; trees are devoted and faithful friends that never reproach us for their benefits, and their love is susceptible of no change, Plants are for us a real panacea. They are the natural pharmacies which Providence has established on earth for the prevention or cure of our diseases. From their wood, barks, leaves, flowers, and fruits, are exhaled essences which strengthen our organs, purify the blood, and neutralize the noxious air around us. The history of all ages shows that those regions which are favored with vast forests have always been healthy and propitious to man; but where the forests have been cut down, those same regions have become marshy and the source of deadly miasmas, The marsh fevers which now prevail in certain parts of Asia Minor render them uninhabitable. {74} Nevertheless, ancient authors speak of marshes of small extent, but not of marsh fevers, because then the forests still remained. A thousand years ago, La Brenne was covered with woods, interspersed with meadows. These meadows were watered by living streams. It was then a country famous for the fertility of its pastures and the mildness of its climate. Now the forests have disappeared. La Brenne is gloomy, marshy, and unhealthy. The same could be said of La Dombe, La Bresse, La Sologne, etc. The following is a permanent example exactly to the point. In the Pontine marshes, a wood intercepts the current of damp air laden with pestilential miasmas, rendering one side of it healthy, while the other is filled with its destructive vapors. The places where forests have disappeared seem as if inhabited by evil genii, who eagerly seek to enter the human frame under the form of fevers, cholera, diseases of the lungs and liver, rheumatism, etc. For example, it is sufficient to breathe for only a few seconds in certain regions of Madagascar, or some of the fatal islands near by, for the whole organization to be instantly seized with mortal symptoms. The most robust and vigorous young man, who goes full of ardor to those shores with the hope of a bright future, affected by these miasmas, feels as if dying with the venom of the rattlesnake in his veins; and, if he recovers from his agony, it is often to drag out in sorrow the small remnant of his days. How many unfortunate people of this class have I not met during my voyage in the Indian Ocean. What a sacrilege to think of destroying these delicious and mysterious forests, with their atmosphere full of celestial vibrations, and their divine orchestra, where the breeze murmurs in a thousand tones the hymn which reveals the Creator to the creature! Every sorrow is soothed in the depths of those beneficent shades. There the soul, as well as the body, finds a repose which regenerates it. The divinity descends; we feel its presence. It moves us to the depths of our souls. It caresses us like the breath of the mother we adore!
