Close to the houses was a steep rack, upon which J found 
several interesting plants, and among them a beautiful new 
Lavendula, and several others met with in the Canaries. 
Below was a clear spring, overshadowed by Pisangs and 
cocoa-trees. Its temperature was one degree higher than

At day-break we heard a shot from the harbour, which
