quently steel-capped rails, highly charged by an inductive current. In one instance, we found a telegraphic wire, unconnected at either end by a battery, highly charged with electricity; messages have frequently been sent several miles using the earth instead of the line wire.

Hear the following meteorological result, as fairly established as any forest influence upon climate:

The natives say that since the terre mote of 1859, the seasons have not commenced so regularly, nor are they so well defined; there are more rainy days in summer than before.. [Orton's Andes and Amazon.]

Here are cases that bear as strongly upon the question of rain-fall as forests, yet electricians do not claim them as available forces, because they lack scientific confirmation. It is to be regretted that men who observe least closely are always most easily reconciled to their theories, and most aggressive in advancing them.

.I wish it clearly understood that I do not deny to forests the exerting of climatic influence, but I do firmly believe that the fact has not been established by fair, honest, scientific investigation and data. Let us, as a body, carefully move toward the truth, trying all things, holding fast to that which proves good, above all things be loth to announce the result of guesses, to as carefully weigh our words as we would the results of the most accurately conducted experiments; then and then only will men place confidence in our deliberations. Then shall our light be of such a nature to the agricultural world that it cannot be hidden under a bushel; yea, it will shine from the top of a hill, even the Capitol hill.
