2. Test Resvilts . 



a. Borers. Teredlnldae were fairly active, especially 

 in the test panels, aljnost throughout the duration of the test, "but 

 none developed "beyond the embryonic or minute stages. The attack was 

 rated as moderate, chiefly on the strength of the numher of individuals 

 present. The changing of the test "board locations, and the "brief period 

 for which either was operated, make it difficult to evaluate accurately 

 the damage from Teredinidae or the full "breeding season in this har"bor. 

 The "breeding season extended at least from June through Octo"ber and pro"ba"bly 

 longer. Limnoria was recorded as only a trace, and no Pholads were 

 o"bserved. 



"b. Fouling Organisms . Silt and inverte"brate animals 

 "belonging to k phyla contri"buted to fouling of the panels. The 

 latter comprised hydroids, filamentous Bryozoa, serpulid worms, and 

 "barnacles. The hydroids euid "barnacles occxirred with great frequency 

 euid regularity, "but the others were represented only as mere traces.
