The winds in general were from E.S.E. to N.E.; though they sometimes varied a few points each way to the N. and S, but these were light, and of short duration. In the harbour of Karakakooa we had a constant land and sea- breeze every day and night.
The currents seemed very uncertain, sometimes setting to windward, and at other times to leeward, without any regularity. They did not appear to be governed by the winds, nor any other cause that I can assign; they frequently set to windward against a fresh breeze.
The tides are very regular, flowing and ebbing six hours each. The flood comes from the eastward; and it is high water, at the full and change of the moon, forty-five minutes past three, apparent time. Their greatest rise is two feet seven inches; and we always observed the water to be four inches higher when the moon was above the horizon, than when it was below.
The quadrupeds in these, as in all the other islands that have been discovered in the South Sea, are confined to three sorts, dogs, hogs, and rats. The dogs are of the same species with those of Otaheite, having short crooked legs, long backs, and pricked ears. I did not observe any variety in them, except in their skins, some having long and rough hair, and others being quite smooth. They are about the size of a common turnspit, exceedingly sluggish in their nature, though perhaps this may be more owing to the manner in which they are treated, than to any natural disposition in them. They are in general fed and left to herd with the hogs; and I do not recollect one instance in which a dog was made a companion in the manner we do in Europe. Indeed the custom of eating them is an inseparable bar to their admission into society; and, as there are neither beasts of prey in the island, nor objects of chase, it is probable that the social qualities of the dog, its fidelity, attachment, and sagacity, will remain unknown to the natives.
The number of dogs in these islands did not appear to be nearly equal, in proportion, to those in Otaheite. But on the other hand, they abound much more in hogs; and the breed is of a larger and weightier kind. The supply of provisions of this kind which we got from them was really astonishing. We were near four months, either cruising off the coast, or in harbour at Owhyhee. During all this time, a large allowance of fresh pork was constantly served to both crews, so that our consumption was computed at about sixty puncheons of five hundred weight each. Besides this, and the incredible waste which, in the midst of such plenty, was not to be guarded against, sixty puncheons more were salted for sea-store. The greatest part of this supply was drawn from the island of Owhyhee alone, and yet we could not perceive that it was at all drained, or even that the abundance had any way decreased.
The birds of these islands are as beautiful as any we have seen during the voyage, and are numerous, though not various. There are four, which seem to belong to the trochili, or honey-suckers of Linnæus; one of which is something larger than a bullfinch; its colour is a fine glossy black, the rump, vent, and thighs, a deep yellow. It is called by the natives hoohoo. Another is of an exceedingly bright scarlet colour; the wings black, and edged with white, and the tail black; its native name is eeeeve. A third, which seems to be either a young bird, or a variety of the foregoing, is variegated with red, brown, and yellow. The fourth is entirely green, with a tinge of yellow, and is called akaiearooa. There is a species of thrush, with a grey breast, and a small bird of the flycatcher kind; a rail, with very short wings and no tail, which, on that account, we named rallus ecaudatus. Ravens are found here, but they are very scarce; their colour is dark-brown, inclining to black, and their note is different from the European. Here are two small birds, both of one genus, that are very common; one is red, and generally seen about the cocoa-nut trees, particularly when they are in flower, from whence it seems to derive great part of its subsistence, the other is green; the tongues of both are long and ciliated, or fringed at the tip. A bird with a yellow head, which, from the structure of its beak, we called a parroquet, is likewise very common. It however by no means belongs to that tribe, but greatly resembles the lexia flavicans, or yellowish cross-bill of Linnæus.
Here are also owls, plovers of two sorts, one very like the whistling plover of Europe; a large white pigeon; a bird with a long tail, whose colour is black, the vent and feathers under the wing (which is much longer than is usually seen in the generality of birds, except the birds of paradise) are yellow; and the common water or darker hen.
Their vegetable productions are nearly the same with the rest of the South Sea islands. I have before mentioned. that the tarrow root is much superior to any we had before tasted, and that we attributed this excellence to the dry method of cultivating it. The bread-fruit trees thrive here, not in such abundance, but produce double the quantity of fruit they do on the rich plains of Otaheite. The trees are nearly of the same height, but the branches begin to strike out from the trunk much lower, and with greater luxuriance. Their sugar-canes are also of a very unusual size. One of them was brought to us at Atooi, measuring eleven inches and a quarter in circumference, and having fourteen feet eatable.
At Oneeheow they brought us several large roots of a brown colour, shaped like a yam, and from six to ten pounds in weight. The juice, which it yields in great abundance, is very sweet, and of a pleasant taste, and was found to be an excellent substitute for sugar. The natives are very fond of it, and use it as an article of their common diet; and our people also found it very palatable and wholesome. We could not learn to what species of plant it belonged, having never been able to procure the leaves; but it was supposed, by our botanists, to be the root of some kind of fern.
Agreeably to the practice of Captain Cook, I shall subjoin an abstract of the astronomical observations which were made at the observatory in Karakakooa Bay, for determining its latitude and longitude, and for finding the rate and error of the time-keeper. To these are subjoined the mean variation of the compass, the dip of the magnetic needle, and a table of the latitude and longitude of the Sandwich Islands.
