Here, at Swallow Bay, a party of our men captured and brought to me a male specimen of the Magellan nutria, an animal which is abundant throughout the straits and western channels, but which is nevertheless very rarely seen. We had often previously seen its bones in the Fuegian midden heaps, where its skull, with the long curved orange-coloured incisors, was a conspicuous object; but this was the first recent specimen we succeeded in getting hold of. It was started from the brushwood by a retriever dog belonging to the ship, and on taking to the water was killed after a most exciting chase on the part of our bluejackets. It proved to be identical with the Chilian species, Myopotamus coypu.


CHAPTER VI.
EXPLORATIONS IN SKYRING WATER.

On the occasion of our last visit to Sandy Point, the captain received despatches from the Admiralty, which authorised him to proceed to Skyring Water in order to investigate the nature of the coal which was then being worked on the north-east of that basin, and to ascertain if it could be made available for the use of men-of-war or merchant vessels, passing through the Straits of Magellan. A favourable opportunity occurring on March 5th, the Alert accordingly got under way from her anchorage at Tilly Bay, and steaming northwards across the Strait, entered the Jerome Channel. Here we experienced a strong current from the northward, which was attributed by Mr. Petley, our navigating officer, to the ebb tide flowing from the Otway Water. This channel is twenty miles in length, from its southern opening opposite Tilly Bay to its northern extremity abreast of Corona Island, where it dilates into the wide expanse of Otway Water. Its shores are lined by precipitous mountains of an average height of 1,000 feet, and clothed to their summits with the dense evergreen forest which characterizes the scenery of the western half of the Magellan Straits. Behind, and towering above this coast range, were hills of a still greater altitude, whose summits were clothed with a mantle of snow and ice—the source of the glaciers flowing to the southward into the main straits. As we entered Otway Water, we saw on our starboard hand a broad expanse of rippling water, limited in the distance by a coastline of comparatively low land, while on our port side there was a marked transition from the lofty mountains of the Cordillera to an upland plain of undulating hills covered with forest, and sloping gradually downwards into low flat land as it extended to the eastward. In fact, we had passed through the backbone of the Cordillera, and were now approaching the alluvial plains of Patagonia; and it was also clear to us that we were crossing the line of demarcation between two climatic zones, for we found that we were exchanging the cloudy sky of the Magellan region for brilliant sunshine and a clear blue sky, a change only to be fully appreciated by those who have spent many months in the damp, cloud-collecting region of the Western Straits.

The north shore of Otway Water was low and shelving, presenting a glistening margin of sandy beach, and fringed by a wide belt of very shallow water. In the afternoon we entered the Canal of Fitzroy, where we encountered a strong current from the northward (i.e., from Skyring Water), which considerably impeded our progress. Indeed, at 4 p.m. we grounded on a sandbank, getting off, however, without much difficulty, and in an hour afterwards we dropped anchor in a bight where an S-shaped curvature in the canal afforded us shelter from the current.

Both shores of the canal are low, and formed of alluvial soil, of which the crumbling banks in places exhibited good sections. Well-marked terrace-levels bore testimony to the fact that the land must have been subjected to upheaval, with reference to the sea-level, at some period in the world's history. The country on the western side of the canal is covered with thick scrubby bush, while that on the eastern side, where we landed for a few hours, was a sort of open park-land disposed in undulating hills, covered with a luxuriant growth of grass, and studded here and there with isolated clumps of trees and bushes, among which we noticed the antarctic beech, an embothrium, a barberry, and a cheilobothrium. The ground in the middle of these clumps was worn bare from having been used as a resting-place by the wild cattle. Herbaceous composite plants grew in great profusion, and many specimens of a lychnis were seen, but unfortunately the season was too far advanced for our obtaining useful specimens of flowering plants. I was surprised at the great variety of grasses which flourished on the dark loamy soil. We saw countless tracks of wild cattle and horses, and a few deer tracks, but in the course of our ramble failed to meet with any of these animals. The existence of a species of Ctenomys was evident from the way in which the ground was in many places so riddled with holes as to be exceedingly dangerous for incautious horsemen; and while walking through the long grass I stumbled over the skull of a puma. We did not see many species of birds. Finches were abundant, and some flocks of the black starling, and also of the military starling, were seen. I got a specimen of a pteroptochus, which resembled the Tapaculo of Chili, but differed from it in having a red iris; and on the beach I shot a cinclodes, which seemed to be of a different species from the common kelp-bird of the straits. A fine buzzard (I think Buteo erythronotus) soared above my head, but out of range; and the tiny wren of Magellan (Troglodytes), completed the list of birds which we saw. During our absence great numbers of black-necked swans and brown ducks were seen in the vicinity of the ship.

The western shore of Fitzroy Channel consisted of a low plain, rising gradually towards the westward, covered with a dense scrub of tall bushes, and contrasting strikingly with the open moorland on the eastern shore.

At five o'clock on the following morning, we got under way and continued our course through the Canal of Fitzroy, steaming for hours through a dense interminable flock of black-necked swans, that paddled lazily to either side as we advanced, as yet in happy ignorance of the thirst for blood which characterizes the British sportsman. As we emerged from the canal, and skirted along the eastern shore of Skyring Water, we noticed two men on foot, walking along the beach. We afterwards learned that they had a day or two previously left the coal mine where they had been employed, and were now attempting the precarious task of travelling on foot to the Chilian settlement, Punta Arenas, in the Straits of Magellan, a distance of ninety miles.

At 10.30 a.m. we reached the bay of the mines (Rada de las Minas), and came to an anchor about half-a-mile from the shore. The settlement was larger than we had expected, and exhibited fair signs of activity, several shingle-built houses, large store sheds, and a steam sawmill, showing out conspicuously against the dark background of forest which spreads for a few miles to either side, and is seen extending inland to near the summit of Mount Rogers, a hill to the northward which reaches an elevation of 1,000 feet.
