of Wales’ Island. – Islands of Preparis, Narcondam, Seyer, and Prince of Wales.
On the 21st November we embarked on the John Adam, nearly opposite to Fort William, and dropped gradually down the river to the sand-heads. We had but one opportunity of going on shore, and this was at some distance above Sauger Island. The land was here eight or ten feet above high-water mark; soil, a very deep, black, light mould, and densely covered with low jungle. Numerous traces of deer, and one very conspicuous track of a tiger, which appeared to have been of enormous size. Carried off a species of Boletus, a species of Laurus, and one of Calamus.
The pilot left us, in smooth water, near to a moored ship allotted for the reception of pilots, and out of sight of land. On the following morning we sailed, with a fair and tolerably strong wind, attended with a sea sufficiently rough to occasion sickness in persons so little accustomed to this dread element. In this manner we arrived off Cape Negrais. While off this point, but still far from being within sight, our ship was visited by two or three birds, one a species of dove, the next another of the Linnean Passeres, and a third a species of Sterna. The latter, as usually happens with others of the same family, either from natural stupidity or from exhaustion, allowed itself to be taken without difficulty.
December 3.– Early in the morning, the island of Preparis, the first land we had yet seen since we left the pilot, was in sight. We stood towards it with the view of landing upon it, and examining its structure; but the wind unfortunately increasing, and the windward coast being only navigable with safety with the ship, it was deemed too hazardous a task to land.
From the distance at which we viewed these islands, it was difficult to form an accurate judgment respecting their structure. The two small ones, called the Cow and Calf, at one time appeared as if they were of basaltic formation; and again as if they were merely banks of coral. Against the latter supposition, their altitude above the sea (not less perhaps than two hundred feet) might seem to militate; but this is not conclusive, especially if there be any truth in the observation, that the great basin which composes this ocean has lost much of its original altitude. It is possible that they may be composed both of basalt and coral; it is highly probable that one or other of these materials constitute their mass, and most probably the latter. The principal island is of a gently undulating shape, rising gradually from the sea, to a slight elevation, and is thickly covered with wood, and apparently tall and wide-spreading trees.
We had the more reason to regret the circumstance of our not being able to land on these islands, from their being the first in the great chain which composes the archipelago.
On the following morning at sun-rise we were within sight of Narcondam, an island apparently several miles in diameter, in form and shape a perfect specimen of the volcanic cone, which we calculated to be about two thousand five hundred feet above the sea. We were at too great a distance to entertain a hope of landing on it. This island, from its height, its solitary existence in a wide sea, and its singular and beautiful form, constitutes a very striking object.
On this occasion we endeavoured to construct an instrument for ascertaining the temperature of the sea at considerable depths, but from the imperfection of our materials, our success was but indifferent. In the only experiment that we performed, the temperature at two hundred and forty feet was 2½° less than at the surface.
The variations on the barometric column we observed to be very regular, being at its greatest height about seven a.m., and lowest towards four p.m.
The weather continued agreeable; the wind steady and moderate, the N.E. monsoon having now set in steadily. Several of the natives on board had been ailing; and one, a sepoy, had a dangerous attack of cholera, but all were now sufficiently in health.
Our course now lay towards the coast, of which we soon came within sight. As we approached the western coast of this peninsula, we could not fail to be struck with the singular appearance of numerous islands, varying in dimensions, situation, and height; an appearance very different from what is observable on the opposite side of this bay, where scarce an island rises a few feet above the water, but which here being strewed over so great a space, seem to form a bulwark, or chain of protection to the continental land.
The bold and elevated ridge in the centre, with the abrupt and rugged points on their flanks, were no less striking, and appeared, even at a distance, to afford ample evidence of their primitive structure. The more elevated mountain ridges on the continent were not less bold or striking in their appearance. The general direction of these ridges, both in the islands and on the continent, is nearly north and south, inclining a little from west to east. Vegetation appears everywhere abundant; the forms principally arborescent.
On the 7th of December, being near to the Seyer Islands, in latitude 8° 43´ N., and longitude 97° 48´ E., we prepared to land on them. These islands are within sight of the continent, and distant from it about twenty-eight miles. The principal one appears to be about five miles in length, and perhaps one in breadth. It was on this that we proposed to land. As we approached in the boat, we were struck with the general silence which seemed to pervade it, a circumstance which appeared to us the more singular, as it was everywhere covered with dense woods, which might be supposed to afford nourishment and safe shelter to numerous land birds, while its rocky coast might have been alike favourable to the existence of water fowl. Scarce a bird, however, was seen to hover over the place. Neither the varied forms of an exuberant vegetation, nor the safe asylum under its peaceful shade, seemed sufficient to attract even a scanty portion of animated nature to this apparently favourable, and certainly very beautiful, spot. Is the proximity of man necessary to give to rude nature an aspect or an impulse favourable for the support of animated creation in its various forms? On this desert island, the tall trees seemed to wave their tops in vain; the more humble shrub and herb flowered unseen, their sweets apparently unappreciated. The useful and friendly palm, the luscious plantain-tree, the scented jasmine, the elegant bamboo, the nutritious yam, were here the spontaneous production of the soil; beautiful at least, and interesting in appearance, though not highly possessed of those valuable qualities, which in a domestic state man has conferred upon them by his care and industry.
As we approached the shore, we were enabled to notice the elevated and nearly perpendicular direction of the rocky mass, which, on more close inspection, was found to be composed of coarse-grained granite, for the most part of a reddish colour; but occasionally of a flesh red, and more often of a gray colour. A well defined, broad, and very white stripe, extending along the whole length of the island, a few feet above the sea, appeared to form the high-water mark. This white appearance was occasioned by a shelly incrustation.
The appearance of the rocks was, in general, very uniform. They were, as already observed, altogether granitic. The inclination of the strata was from N.E. to S.W. Though the character of this granite was extremely well defined and prominent, it yet appeared a difficult task to pronounce an opinion respecting its stratification. In one part might be seen large, perfectly homogeneous masses, fifty or sixty feet in thickness, without rent, fissure, or division, without the slightest appearance of stratification; with the solitary exception of the occasional occurrence of a seam or narrow vein of quartz, or of finer-grained granite, crossing its surface. But by far the most common appearance in this granite, was that of a tolerably uniform stratification, the strata of unequal thickness, and crossing the direction of the mountain ridge at an acute angle. These strata were again irregularly divided in most parts, so that the whole seemed to have a double stratification, or to be divided into irregular trapeziums. The granite was almost universally coarse-grained, containing chiefly quartz and feldspar, with but little mica; the crystals of feldspar varied in size from a grain to nearly an inch. This coarse-grained granite occasionally passed into one of very fine structure, and here and there into gneiss, though the latter was always of small extent. The rock was for the most part divided into numerous sharp and needle-shaped points. Though on a lee shore, there was here a considerable surf and swell, to impede our landing. A solitary water-fowl was seen to wander from rock to rock, collecting food from the pools, which abounded with small fish. After a little care, we landed in safety on the rocks. We observed a considerable variety of corals, crabs, and shells. Of the genus Patella, some species were uncommonly large. Distracted with the multitude of different objects before us, rocks, crustacea, vegetables, &c., we turned from the sea-shore, and entered the forest. We had now reached the region
