The surface waters from lakes and ponds, and the ground waters from sands and gravel, are well known resources from which extensive public and private water supplies are often obtained; but the history of water supply engineering fails to furnish one instance where a forested area, as such, has been given any consideration in the selection of a water supply. General Chittenden after a somewhat detailed study of this question arrived at the following general conclusions, which the writer believes to be substantially correct: CoNoLUs1oNs OF GENERAL CHITTENDEN ON Fomzsr INFLUENCES (1) "The bed of humus and debris that develops under forest cover retains precipitation during the summer season, or moderately dry periods at any time of the year, more effectively than do the soil and crops of deforested areas similarly situated.
