"Magallanes, Señor, fué el primer hombre Que abriendo este camino le dió nombre." Ercilla Araucana, Cant. I. oct. 8. During an excursion with Mr. Tarn to Eagle Bay,[33] beyond Cape San Isidro, we found many wigwams. They were then novelties to us, and we were ignorant of their being such certain indications of very sheltered places, as subsequent experience has shown them to be. We often used them, after they had been well cleaned out: a boat's sail, thrown over the hemispherical roof, was a sufficient protection from rain;--and from wind they are always well defended by their situation. Here we saw, for the first time, that most remarkable bird the Steamer-duck. Before steam-boats were in general use, this bird was denominated, from its swiftness in skimming over the surface of the water, the 'race-horse,' a name which occurs frequently in Cook's, Byron's, and other voyages. It is a gigantic duck, the largest I have met with. It has the lobated hind-toe, legs placed far backwards, and other characteristics of the oceanic ducks.[34] The principal peculiarity of this bird is, the shortness and remarkably small size of the wings, which, not having sufficient power to raise the body, serve only to propel it along, rather than through the water, and are used like the paddles of a steam-vessel. Aided by these and its strong, broad-webbed feet, it moves with astonishing velocity. {36} It would not be an exaggeration to state its speed at from twelve to fifteen miles an hour. The peculiar form of the wing, and the short rigid feathers which cover it, together with the power this bird possesses of remaining a considerable length of time under water, constitute it a striking link between the genera _Anas_ and _Aptenodytes_. It has been noticed by many former navigators. The largest we found measured forty inches, from the extremity of the bill, to that of the tail, and weighed thirteen pounds; but Captain Cook mentions, in his second voyage, that the weight of one was twenty-nine pounds.[35] It is very difficult to kill them, on account of their wariness and thick coat of feathers, which is impenetrable by any thing smaller than swan shot. The flavour of their flesh is so strong and fishy, that at first we killed them solely for specimens. Five or six months, however, on salt provisions, taught many to think such food palatable, and the seamen never lost an opportunity of eating them. I have preferred these ducks to salt-beef, but more as a preventive against scurvy, than from liking their taste. I am averse to altering names, particularly in natural history, without very good reason, but in this case I do think the name of 'steamer' much more appropriate, and descriptive of the swift paddling motion of these birds, than that of 'race-horse.' I believe, too, the name of 'steamer' is now generally given to it by those who have visited these regions.
