APPENDIX. 217 



out comes a jet of pure water. The buds of tlie wild ginger hold 

 water too, but not so much, and it has a decided taste. And all 

 this is not in the ravines, but on the ridge along which we walked 

 all the time." (p. 211). 



JSTo. 4 — >S'i!^. Vincent's. 



The following tables of temperature and rain fall in St. 

 Vincent's, during the period mentioned (at p. 18) from 1823 to 

 1829, were forwarded to me in 1885. They have never been 

 published till now. With them came a memorandum which 

 I here copy. " From the little variation of the temperature 

 there is' much deviation from the laws observed in more variable 

 climates. Our plants are less affected by the seasons than by the 

 soil, the elevation and the exposure, and are therefore developed 

 without regularity The Demerara Indians are said to date the 

 progress of their seasons from the flowering of certain plants,, 

 commonly known. I have before mentioned the fall of rain in 

 St. Yincent ; a journal of the Barometer would be of little interest. 

 Its range on the coast is very trifling, and the column will remain 

 for weeks without altering the convexity of the mercury. How- 

 ever, when taken to the summit of mountains it experiences very 

 extensive changes, and accordingly I have been able with one of 

 Dollond's instruments to measure our higher lands with all the 

 necessary accuracy. On the coast of St. Vincent, the instrument 

 rarely foretells anything but some violent hurricane." — [L. Gr., 

 May 1, 1830.]
