ON THE INFLUENCE OF FORESTS UPON CLIMATE. At the meeting of the Royal Meteorological Society, held on Wednesday, Dec. 16th, a paper on the above subject, by Dr. A. Woeikof, was read, of which the following is an abstract :— The existence of an influence of forests upon climate has often been contested, and the question remained for a long time unsettled, because meteorologists were content with prin- ciples of too general a character. The first step towards a scientific investigation of the subject wa3 taken by the establishment of the Bavarian Forest Meteorological Station, the results of which have been published by Pro- fessor Ebermayer. The excellent example of Bavaria was soon followed by , Switzerland, Italy, and other countries. As a general result it was found that during the warmer season (1) the air and earth tempera- tures were lower in the forest as compared with contiguous woodless places ; (2) their variations were less; and (3) the relative humidity was greater. The following details, referring to the amounts of evaporation from April to Septem- ber, are quoted as being of special importance : In the In the Per Open. Ins. Eastern France 16 "23 Alsatian Mountains 13 19 Bavaria 14 85 Brandenburg 1571 Eastern 9-33 Silesian Mountains 10 52 It will therefore be seen that the evaporation from a free surface of water in the open was everywhere more than double, and even above three times that in the forest. In Bavaria, the evaporation from soil saturated with water was observed. This amounted in the same seven months to 16 7 in. in the open, 6 26 in. in the forest without dead lea
