feet, while several others are 2,500 feet or more in height. The 

 coast is generally very rugged, except for a narrow beach on either 

 side of Plymouth, about three miles long, and one of smaller ex- 

 tent on the windward side. There are no enclosed bays and the 

 several salt marshes are very small. Two of those which I ex- 

 plored contained little of interest, except for the fact that most 

 of the species one would expect to find there were absent. In 

 one I found a few small bushes of black mangrove, Avicennia 

 nitida L. A third marsh, which I saw from the distant hills, is 

 said to contain mangroves, but I was unable to visit it or to ascer- 

 tain which of the three genera they represented. 



The beach affords the usual plants common to a similar envi- 

 ronment throughout the West Indies, while the old-world plants, 

 Vinca major L., the. periwinkle of our gardens, and Calotropis 

 procera R. Br., the so-called French cotton, were very conspicu- 

 ous, the former exceedingly abundant. The much-feared man- 

 chioneel, Hippomane mancinella L., is very abundant and reaches 

 large dimensions. The most common woody plants near by are 

 "wild coffee," Clerodendron acideatum (L.) Griseb., "French 

 cashaw," Prosopis juliflora DC. and the *' cashaw," Acacia tortuosa 

 Willd., the latter very common throughout the dryer portions of 

 the island. On the coastal cliffs the dry thickets are composed 

 of a variety of shrubs and stunted trees, conspicuous among them 

 being several species of Croton, Plumieria alba L., and a tall 

 upright cylindrical cactus belonging to the genus Cereus. 



On' the windward side the bleak wind-swept cliffs support a 

 species of Agave, two prickly pears, Opunlia, aTurk's-cap cactus, 

 Melocactus, and Plumieria alba L., while the more gentle slopes are 

 covered with an impenetrable thicket composed mostly of the 

 currant tree, Jacquinia armillaris L., and " white cedar," Tecoma 

 Leucoxylon Mart. The northern end of the island is very rough, 

 rocky and dry, its highest point, Silver Hill, being less than 

 1,300 feet. It is covered with a xerophytic growth composed 

 largely of the above-mentioned plants, together with fiddle-wood, 

 Citharexylum quadrangulare Jacq., white alley, Guettarda, three 

 or four species of Coccoloba, and a great variety of other woody 

 plants in lesser numbers, among which are found several orchids
