* The mean temperatures are given by observations extending (with some lacunce) from Angast, 

 1855, to March, 1877. The temperature of the soil at 6 inches is the mean between observations at 9 

 a. m. and 5 p. m., apparently the hours of extreme daily range. The temperature at 12 inches is that 

 at 9 a. m. ; the daily range at this depth is under 0°.5, and is about the mean at 9 a. m. 



The eartli temperatures are probably very near the true mean temper- 

 atures of the air. The rainfall is not the same all over the island. It 

 is decidedly greater in the broader and more wooded region towards the 

 center than at either extremity, and is least about the light-house, where 

 the island is narrow and comparatively denuded of wood. There are 

 grounds for supposing, also, that the mean temperature at the east end, 

 probably under the influence of the cold northeast winds of winter, 18 

 lower than in the central regions; but these are niceties not affecting 

 the present question. 



Under the conditions of climate thus briefly described the cocoanut 

 and sugar-cane grow, but not to perfection. The writer had no success 

 with pine-apples, although they were formerly grown in Bermuda. The 

 orange, lemon, lime, fig, mango, banana, pawpaw, avocado pear, pome- 

 granate, loquat, litchi, and the anona family come to perfection. Straw- 

 berries and excellent celery, with all ordinary vegetables of the table, 

 thrive in the winter. Api^les, pears, plums, cherries, almonds, apricots, 

 nectarines are a complete failure. The raspberry and blackberry die 

 out, and neither rhubarb nor asparagus can be grown to any satisfac- 

 tion. The peach, although not now actually produced, all the trees in 

 the island being infested by the peach fly, was very abundant twenty 

 years ago, and therefore differs from other stone fruits, in being suitable 

 to the climate. 



The reader of the following list will notice frequent references to "the
