Before taking leave of Georgetown we must mention the three chief points of attraction. The sea-wall comes first and, as we have said, a most pleasant custom of the natives is to drive there in late afternoon and sit in their carriages. The concrete break-water is of vital importance to the town itself as a portion of the streets are below sea-level. The broad summit forms a mile or more of promenade, with a sandy beach on one side, lapped with waves which strive ever to break, but cannot because of the thick sediment which they hold in suspense. On the other side a double row of tall, graceful palms adds a touch of tropical beauty. The residences near the sea-wall are the coolest and most pleasant in the town and are practically free from mosquitoes. We spent more than one delightful evening in the garden at Kitty Villa as the guests of our charming American friends, Mr. and Mrs. Howell. From the open, veranda-like rooms one may watch the Yellow Orioles,[159] the Brown-breasted Pygmy Grosbeaks,[129] the Anis and Kiskadees going to roost. Just before dusk scores of the small Black Vultures[51] appear, flying singly, or in twos and threes low over the trees and palms westward to some general roost. About this time the bats and the lightning bugs arrive, large numbers of very tiny bats hawking about after insects, and several large fruit-eaters with wings spreading almost two feet across. These haunt the fruit-laden sapadillo trees, and as the method of feeding of these curious creatures does not seem to be generally known we watch it with interest. One of the big fellows flits here and there, nipping first one fruit and then another. At last when a sweet or fully ripe one is found, the bat swoops up to it, alights head downward, and half enveloping it with his wings, bites away frantically for two or three seconds and then dashes off. This is repeated until darkness settles down, but never does the wary bat linger over his feast. In the north the sight of a single bat darting along on its eccentric way is not uncommon, but here we were soon to become accustomed to the sight of scores, some pursuing insects, or feeding on fruits, or waiting and watching for a chance to drink the blood of men and animals. More than twenty-five species have been found here within a few miles of the coast. Small Owls and nocturnal insectivorous birds are somewhat rare, and thus the bats have few foes and little competition in their aërial life.
