A55.OI Location of the Test Station and Test Boards 



Four test boards of the panel type vere installed Aiigust 10 > 19li4, 

 at different locations at the U. S. Maval Advanced Base Depot on Espiritu 

 Santo Island, New Hel)rides. Because of the varying conditions, four 

 representative locations were selected. Two of these locations were in 

 Segond Channel, one in Pallufculo Bay, and one in Turtle Bay, "but the exact 

 locations were. not disclosed for security reasons. It appears from 

 correspondence, however, that Station No. 2 was on Aore Island, which is 

 sepeurated from Espiritu Santo Island "by Segond Channel. The test hoards 

 at Stations 2 and k were missing on the inspection date in Octoher 19^5* 

 apparently having "been carried away diiring a stom. The curtailment of 

 military actlvi-ty at that time made it necessary to discontinue the 

 operation of the hoards at these stations, and the opei^tion of those 

 "boards at Stations 1 and 5 was discontinued after January 10, 1946. These 

 test boards were designated by the symbols USHXX-1, 2, 5> sjid. k,

 throughout the period of the test, occurring in every control and test
