A paper on the average rainfall of the last ten years has appeared from the Signal Service Department at Washington. Our rains come from the vapor which rises under the warm suns over the Gulf of Mexico. The ice of the North prepares a cold heavy current, which rolling down towards the lighter column of the Gulf draws the lighter northward to fill the vacuum. As the colder meets the warmer rain is precipitated, and this would be exactly the same if there were not a tree on the whole Atlantic coast. These show that notwithstanding the awful destruction of the forests of which the newspapers and some magazines tell us, the rainfall of the past ten years is just the same as that of the ten years previous. It is the de-minution of the ice towards the pole that we have to fear, rather than the diminution of the forests, when we calculate on our country becoming an "arid treeless waste".
