2. Test Resulta , 



a. Borers . Teredlnldae were active in all the panels 

 throughout the "brief period of the test, the breeding season apparently 

 "being continuous. The attack rated very heavy in panels exposed only 

 k months. Limnoria also were active in all the panels throughout the 

 test, the attack rapidly hecomlng destructive and rating heavy. No 

 Pholads were recorded at this location. 



"b. Fouling Organi833ia . Silt and inverteljrate animals 

 "belonging to 5 phyla contri"buted to fouling of the panels. The iilverte"brates 

 comprised hydroids, encrusting Bryozoa, serpulid worms, "barnacles, and 

 mussels. Silt and hydroids occurred regularly on all the panels. 

 Encrusting Bryozoa, serpulid worms, and "barnacles occurred less frequently, 

 and mussels only once. 



The operation of the test "board was not continued long enough 

 to provide conclusive information on the "breeding ha'bits and development 

 of the marine "borers and fouling organisms at this location, "but the 

 conclusions reached from its study show the general trend.
