The western point of Palo Uhin is eminent ]y beautiful. A group of large blackish wave 

 worn rocks advance in front into the lea f and, from the acutcuess of the Pointy (hence by

 of other and probably still larger rock* are partially seen through the branches and in the

I natct only partially examined the northern coast near the eastern and western points, 

 Rot far from the latter there is a very large grooved rock half concealed by mangroves. 

 The grooves are curved in their descent and those at one placo in an opposite direct ion to the 

 other*. The groove* facfi fl, by NW, After passing a paan^rovc tract to the eastward the
