The Ceard stone reef. — I have seen the Ceara reef, but have never 

 made a personal examination of it. The following notes are taken from 

 Sir John Hawkshaw,^ who examined this port in 1875. 



Ceara is in 3° 43' south latitude, 38° 33' west of Greenwich. Mucu- 

 ripe Point spoken of is " about seven kilometres to the eastward." Mucu- 

 ripe Point consists of sandstone rock, and is covered on shore with sand 

 hills, but the low underlying rocks extend half a mile seaward at low 

 water. "Mucuripe Point gives the roadstead of Ceara the appearance of 

 a bay, . . . but the rocks project too little seaward and lie at too low a 

 level to afford perfect shelter to the more distant anchorage at Ceara. 

 There are more rocky shoals west of Mucuripe Point, with deep water 

 between them, such as Meirelles reef, the Estrella Bank, the Yelha reef, 

 and the Coroa Grande shoal. . . . The Eecife do Porto, a reef of sand- 

 stone stretching out in a diagonal direction from the shore at the east 

 end of the town, is incorrectly shown on most of the charts. It gives 

 some amount of protection at low water to Hghters and small craft, but 

 as the waves always wash over it except at low water equinoctial spring 

 tides, this protection is very insufficient."
