Caroline Atoll situated between I 50 14* Etnd I 50 13 west longi¬ 
tude and 9 55’ 10 55' south, latitude is’ composed of three large 
islands. Two of these, Nake Island and Long Island are separated by 
a mud flat at low tide. Togather these two islands form a land mass 
approximately 2,2 miles long at the north end of the atoll. South 
Island is about 1 mile wide and ,35 miles long at the widest point. 
In between these islands which form the north and south extremities 
of the atoll are numerous small islets ranging from a few acres to 
less than a half acre in extent. The largest of these Arundel, Bro¬ 
thers and Pig Islands lie on the mndward side of the atoll. Many 
of the smallest islets are found on the leeward side. The atoll is 
approximately 5*35 miles long with the land mass lying at an angle 
to the northeast as far as the southern extremities of Long Island 
and cxxrving toward west of noxi:h along the length of Long Island 
and Nake Island,
