    The interception of rain and snow in the forest-canopy is a factor of sufficient magnitude to require its measurement in any complete study of the hydrology of forested watersheds. In experiments set up to measure the relations of watershed-runoff and infiltration to precipitation it is particularly essential to measure net rainfall reaching soil under the forest-canopy, rather than total precipitation, in order to estimate adequately the amounts of water available for runoff.
