Few animals are found in the forests and mountains of Grenada. The agouti, the armadillo, and the opossum, are sometimes, though rarely, seen. The only quadruped I ever met with in my rambles was an opossum, which I shot as it was climbing a tree. Of reptiles there are none in the mountains. There are several kinds of snakes in the island, some of which have never been described by naturalists. The species which is most common is a black snake (constrictor) of large size, being frequently eight or ten feet in length, and three or four inches in diameter. These snakes are treated not only with forbearance but kindness by the planters, and in return render important service on the sugar plantations, being most persevering and successful RAT CATCHERS; rats are abundant, and exceedingly destructive to the sugar cane, on which they subsist during a considerable portion of the year. None of the serpents in Grenada are poisonous, but in some of the islands, particularly St. Lucia, there exists a snake which resembles the rattlesnake in the ferocity of its attacks and the deadly venom of its bite. Having no rattles, no warning of danger is given to the unwary traveller until the snake darts from its ambush and inflicts a fatal wound; hence the name given to this dangerous reptile is the LANCE DE FER.
In penetrating those mountain gorges, and climbing those mountain ridges, steep and thickly covered with forest trees and vines of many kinds, and of luxuriant growth, I sometimes passed hours without meeting any sign of life, except the flitting and hum of the humming-bird, and the loud and musical coo of the ramee. That mountain wilderness seemed the chosen home of the humming-bird. I there met with many varieties, some of which were exceedingly beautiful. My appearance in those forests caused them much surprise, and to gratify their curiosity they sometimes flew towards me, and hovered within a few feet of my face, as if eager to examine my appearance and learn what object led me to intrude on their mountain haunts.
There were, however, other and less interesting inhabitants in that region, as I one day discovered to my great consternation. I was passing up the bed of a small stream, where the water, by attrition during many ages, had worn a chasm or "flume" through the solid basaltic rock, the walls of which rose at least a hundred feet nearly perpendicularly, when I found an obstacle to my further progress in the shape of some large rocks, which had fallen from above and blocked the passage. I was unable to scale the CHEVAUX-DE-FRISE; but the whole body of water poured through an aperture three or four feet above the bed of the stream; and although it looked dark and dreary within, instead of retracing my steps to find another route through the woods to the spot I wished to reach, I determined to force my way into the gloomy cavern, with the expectation of being able to emerge on the opposite side.
I listened for a moment at the mouth of the aperture, but heard only the murmuring of the stream as it swept along through the uneven channel. I then thrust in my head, when I heard a rushing noise as of the flapping of a thousand wings, and the next moment I was sprawling on my back in the water, having been summarily capsized, partly by force and partly by an involuntary start of terror!
I raised my head and beheld a legion of BATS, some of them of uncommon size, issuing in a stream from the mouth of the cave. These animals in the tropics are numerous, and seclude themselves from the light of day in caverns or other dark and lonely recesses, where they attach themselves to the roof, and clinging to each other are suspended in large pyramidal clusters or festoons. When disturbed, they take wing, and hastily quit their abodes. By unthinkingly intruding on their territories, which had probably never before been invaded, great alarm was excited among the inmates; a terrible confusion ensued, and the general rush to the aperture caused my unceremonious overthrow.
In one of my mountain excursions, I lost my way while enveloped in a dense mist, and, after descending a steep ridge, came upon a platform or terrace of several acres' extent, which at first view seemed to have been formed by artificial means on the mountain side. This plain was level, and thickly covered with coarse grass, which, finding a genial soil and region, grew to a height of five or six feet. Near the centre of the prairie stood the only tree which flourished on this fertile spot. It was a silk cotton tree. I made my way through the grass with difficulty to the tree, which by measurement I found to be twenty-five feet in circumference larger than any other tree I ever saw in the island. Immense branches shot out horizontally about twenty feet from the ground, extending to a distance in every direction from the trunk sixty or eighty feet. Indeed, the gigantic size of the tree, its rich and luxuriant foliage, and its noble and majestic appearance, were in perfect keeping with the place. I tarried some time beneath its branches, and gazed with interest on the picturesque scene, regretting that I had no companion to share my admiration, and thinking that as doubtless no human being, unless some wild Carib in days of yore, had ever previously visited that singular spot, so it was likely centuries would pass away before any other individual would chance to behold and admire that beautiful terrace on the mountain side. I then plunged among the trees and vines growing upon the steep declivity on the further side, and, after a precipitous retreat of two or three hundred feet, heard the murmuring of a stream below, by following which I at length reached a cultivated district.
The clouds on those mountain tops often collect with extraordinary quickness, and, while the sun is shining brightly on the cultivated lands, pour down the rain in deluging showers, which, rushing in cataracts through the gorges, swell the rivers unexpectedly, sometimes causing fatal disasters by sweeping away horsemen or teams when fording the streams. The rise of a river from this cause is sometimes alarmingly sudden; the water comes down in solid phalanx, six or eight feet in perpendicular height, and extends from bank to bank; and with irresistible force sweeps down rocks and trees, shaking the earth on the banks, and making a loud and rumbling noise like distant thunder.
The vicinity of Grenada to the continent causes this island, as well as Tobago and Trinidad, to be exempt from the hurricanes which have proved a terrible scourge in several of the Windward Islands, and from time to time have been terribly destructive to life and property. In Barbadoes, on the 10th of October, 1780, nearly all the plantations were ruined by a hurricane of inconceivable fury, and between four and five thousand persons lost their lives. Grenada has only once been visited by a hurricane since its first settlement by a French colony from Martinico, in 1650. But this hurricane was the means of removing a far greater evil, the circumstances attending which were of an extraordinary nature, and which I shall relate as I learned them from the lips of many who were witnesses of their occurrence.
It was about the commencement of the present century that this island suffered much from a visitation, which threatened to bring famine and desolation, and destroy, not only the present, but the future hopes of the planter. There suddenly appeared, simultaneously in different parts of the island, a great number of BLACK ANTS, of large size, being fully an inch in length, and of a kind until then unknown in Grenada. They probably belonged to the species known as "the large black ant of Africa," remarkable for its boldness and voracity. Although the inhabitants of that fruitful island were wont to treat strangers with hospitality, they were inclined to depart from their usual habit so far as related to these new and strange visitants, who seemed inclined to be more troublesome than was consistent with the welfare of the old residents.
In the course of a couple of years the number of these invaders increased to an incredible amount; they attacked the fruit on the trees and the vegetables in the gardens; and the fields of sugar cane, once so green and flourishing, soon looked as if a fire from heaven, the scourge of an offended deity, had passed over them. Not only the fields, but the trees, the roads, and the dwelling houses, were covered with these ants; and when all sustenance was destroyed in one quarter, they took up their line of march in immense armies and proceeded elsewhere in search of food. In these migratory excursions, if they came to a brook or small river, their progress was not stayed. Those in front were impelled into the stream by the pressure from behind; and, although myriads were swept away and drowned in the rushing waters, many were borne to the other side and continued their journey. In some cases, where the current was not strong, a sort of living bridge was formed, over which immense numbers of these pestiferous insects passed in safety and dry shod. Nothing seemed to check their progress or reduce their numbers.
