Tree Surgery

In November of 1935, Gilbert McLean, tree surgeon, and Doris Cook, a nurse at Tacoma General Hospital, compare surgical methods while examining a wind damaged tree in Wright Park. McLean, an arboriculturist with the Metropolitan Park District, worked from 1928 to 1932 with the Davey Tree Expert Co. He has treated the damaged tree's cavities with the "Davey System." First, he carefully cleaned the wood around the wound. Then he packed the hole with cement to keep the water out and coated the filling with emulsified asphalt as a preservative. Miss Cook stated that thankfully cement and asphalt were never used in the operating room at TG.
