M. Faribault, Minnesota, desires "to know whether the lowering of the water level of some lakes is not an evidence that the rain-fall is diminishing by the cutting away of the forests?" We have no wish to revive this controversy. We will only say that if it is evidence to him, it is not to us. Lakes sometimes rise as unaccountably as they fall, and we are inclined to think no one knows why. Never mind the lakes, however. Plant trees. We shall need all for timber, whether the lakes rise or fall or not.
