In December 1941, the writers visited the exposure location of the North Florida Test Service on Ponce de Leon Inlet, near Daytona Beach, Florida, for the purpose of examining the extent of borer attack in this locality, and to determine the station's suitability for exposure tests on treated piling and for tests in the related field of marine fouling. Arrangements were effected for exposing a series of gum pine blocks throughout the year 1942 to record the progressive borer attack, and simultaneously, to record the growth of all marine fouling organisms prevalent at this location.
