According lo the notices which are to be found on some 

 maps, there can be no doubt that the four islands to the 

 N.W.N, are of the same submarine volcanic nature. 

 Mayo and Bonavista may be compared with the lower 

 part of St. Jago, and Togo is in all likelihood the only 

 volcanic one. The climate of the island is delightful, 

 and considering its situation within the tropics, it is re- 

 markably temperate. Of this the nature of the vegetation 

 gave evident proofs. There were found very few tropical 

 plants in proportion to the number of those which are 

 common in temperate countries. The temperature which 

 has been given for its wells probably does not much differ 

 from the mean temperature (isothermosj of the island 

 It was with difficulty I could draw the information from 

 the inhabitants that it is now about a month or six weeks 

 since the rainy season commenced. The Adamonia^ 

 Jatropha, and Ziziphiis were alread}' stripped of their 

 leaves, and the Mimosa was producing new ones. Almost 

 all annual plants were decayed by drought. The rainy 

 season was said to last from five to six months, and to 

 continue to the end of September. The atmosphere, after 

 being heated in traversing the continent of Africa, is after- 

 wards fully saturated in passing over the sea, and arrives 

 at this island in a humid state, so that the fog comes down 

 at the slightest degree of cooling. The mountains, even 

 those of less height, are almost constantly covered with 

 clouds. At the height of 1400 to loOO feet, the ap- 

 pearance of the country is completely changed. The 

 hills are covered with grass of a tropical form and magni-
