Measurements taken during 21 rainstorms indicated considerable differences in the capacity of Pinus resinosa and P. strobus to retain stem-flow water. Further field and laboratory measurements enabled estimation of stem and crown retention of rain water. An example is given to show that a plantation of 38-year-old red pine may retain 0.03 inches or more of rainwater and that about 40 percent of this retention occurs in the bark of the stem. The comparable value for white pine is about 0.02 inches.
