The foKar transpiring power of Tilia was found to increase in dune environments from an index of o. 15 on the forested Tilia complex to in the most exposed situations on the open sand. In habitats between these extremes the transpiration power was found to be directly proportional to the relative exposure. 4. The morning rise in the daily march is more rapid on the open sand, where it reaches a maximum i to 2 hours earlier than in forested Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hanover, Ind. : J.
