The oyster, which is a true Ostrea edulis, is found in beds, at low water, or taken with the dredge. It is about the size of the native oyster of England, and not at all inferior to it in flavour. In Agüeros's account of Chilóe, he notices this excellent shell-fish; but remarks, that the islanders are ignorant of the value at which it is appreciated. It is rather curious, that, excepting in the neighbourhood of Chilóe, the oyster is very rarely to be met with on the South American coast, while there it is in the greatest abundance. We have never observed any shells of this fish anywhere between the river Plata and Chilóe; nor is it known elsewhere upon the western coast, I believe, to the southward of Guayaquil, which is very near the equinoctial line.[[158]] The oyster-shells at Port San Julian are fossils. Of the Linnæan genus, Ostrea, there are many sorts, on all parts of the coast, both east and west, but they are what we call the pecten or scollop. At Coquimbo, a species of scollop is much used as an article of food, and called oyster; but it has no further right to the name than because Linnæus classed them all as Ostrea, and Molina describes this to be Ostrea edulis.
The pico, which is a barnacle, grows to a very large size; at Concepcion, however, it is still larger, being six or seven inches in length. It has, when properly cooked, very much the flavour of a crab, and by the inhabitants of this Archipelago is considered preferable to any other shell-fish.
Before concluding this imperfect description of the shell-fish of Chilóe, the piure claims some consideration, if it be only for its peculiar and disagreeable appearance. It was considered by Molina as a genus allied to Ascidia (Mol. i. 214), none of the varieties of which are inviting in their look, as an edible substance, but the piure is still less so. It is thus described by Molina: "The piure, scarcely deserving the name of a living animal, is as remarkable for its figure, as for the manner in which it is lodged. The body is about the size and shape of a small pear, an inch in diameter; or it may be described as a small, conical, fleshy bag, of a red colour, filled with saline liquor, and provided with two trunks or processes in the upper part, one of which is the mouth, similar to that of the Tetias; and between these processes are seen two small, black, and shining points, which are supposed to be the eyes. I could distinguish no other organs, nor any viscera in the fleshy substance of which it is composed, which is smooth without and spongy within. They are extremely sensitive, and when touched, spout water out of both apertures. These small animals are shut up in a firm, but glutinous case, of various shapes; one case often contains eight or ten distinct bodies, separated from each other by cells, formed of a strong membraneous substance. They are attached to rocks or stones, under water, excepting when left uncovered by a low tide. The natives eat them boiled, or roasted in their shells. They also dry them for exportation to the province of Cusco, where their flavour is much esteemed, and considered equal to that of the lobster."
At Chilóe, the piure is said to be a remedy for barrenness; and to such an extent has this idea prevailed, that a Chilote woman, eating this fish, literally says, if asked what she is doing, that "she is making children." One would not, however, suppose, from the number of children which are seen
crowding round the doors, that the Chilotes had any necessity for such food.
If one may judge from the few applications made to our medical men for advice, the climate is either very healthy, or the natives prefer their own mode of cure. They have very few medical advisers, and those few are not held in much estimation, being people of little or no education. A prejudice against medical men has been, even in late years, extended to foreign practitioners, and carried to great lengths. This illiberal feeling is, however, fast wearing away; but, among the lower orders, the application of herbs and other simples is yet wholly resorted to for the removal of their complaints. One day, when I was employed in making some astronomical observations, at Sandy Point, a woman passed me, and forcing her way through a thicket of thorny plants, began to gather branches of a species of arbutus (A. rigida.), a small shrubby plant, which is every where abundant, especially to the south, and in the Strait of Magalhaens. My curiosity prompted me to inquire her reason for collecting it with such apparent anxiety. She replied, with a desponding air, "It is chaura[[159]] for a poor, sick child. These branches," she said, "are to be put into the fire, and, being green, will produce a thick smoke, and yield a very strong aromatic smell. The child, who is only five months old, is to be held over it, which, as they say, is a good remedy; but," she added, with an air of doubt, "I know not (dicen que es bueno, pero yo no sé)." "Who says so?" I asked. "Los que saben (those who know)," replied the half-credulous mother, with a deep sigh, partly doubting the efficacy of the remedy, but unwilling to lose the advantages of whatever virtue it might possess, for the benefit of her sick infant.
The climate of Chilóe is considered, by those who live in other parts of Chile, to be "rigorous, cold, and damp." Certainly there is much reason for such an opinion, particularly in the winter months, when it almost always rains, and the wind, with little cessation, blows hard, from N. to N.W., and,
by the W. to S.W.; but notwithstanding the great quantity of rain that falls, the evaporation is great, and it cannot therefore be called unhealthy; indeed, from experience, it is considered quite otherwise. Agüeros, to whose excellent account of Chilóe I have so often referred, dilates much upon this subject, and from having resided there a considerable time, may be taken as the best authority. Those who now reside upon the island speak very much against it, and all whom I met, previous to my visit, condemned it, as being "the worst in the world." Perhaps we, who had lately been experiencing a much more disagreeable climate, went to Chilóe with the expectation of finding it exceed in severity that to which we had been accustomed in the Strait of Magalhaens, but we found ourselves agreeably mistaken. Our visit certainly was in the better season, and we had, perhaps, no right to form a decided opinion upon the other part of the year. I shall, therefore, first quote Agüeros, and then describe what we found the weather from September to December; yet as these months were considered by the inhabitants to be finer than is usual at that season, we can only form a vague idea of the spring and summer. For the autumn and winter I must depend upon the accounts of others.
After explaining the contra-position of the seasons, to what is experienced north of the equator, with regard to the months of the year; Agüeros says, "Chilóe has also its four seasons, but does not enjoy the benefit of those changes, as do other parts of Chile; for there is neither that abundance of fruit, nor are its fields adorned with so many and such beautiful flowers, and useful medicinal plants. The summer is the best time; for in the month of January, from ten o'clock in the morning till three in the afternoon, the heat is excessive. Between these hours, however, a sea-breeze, which is called 'Vira-zon,' refreshes the air. In the winter the temperature is very cold; but the frosts are by no means so severe as in Europe. I have never seen ice, even in the small streams, nor does snow lie any length of time on the ground.
