The island of Tobago presents an extremely picturesque scene. It is a heap of rocks skillfully cultivated. The dazzling whiteness of the rocks stands out from the green of the scattered trees. High cylindrical cacti crown the mountain tops and give a peculiar quality to the tropical countryside. Just this sight tells the traveler that he is looking at the American coast, because the cacti are as unique to the New World as heaths are to the Old.
