sir c. hardy's islands. 



July 12. — Sir Charles Hardy's Islands are three 

 small rocky islands, covered principally with coarse 

 grass ; a few small trees, or bushes only, growing in

 reous sandstone, with corals and shells, was found 

 here and there above the reach of high water, with 

 pandanus trees growing upon it, but not sensibly 

 differing in structure or appearance from the mass 

 of the reef that was covered at high water.

 which a set of angles was wanted. Wc anchored 

 among Sir Everard Home s Group, and the next 

 day landed with a party of six men, all being well 

 armed, but did not see a single native, nor any 

 trace of one. From the top of the hill over the 

 Cape, which was about 400 feet high, we looked
