BY CHARLES WILKES, U,S. N., MEMBER OF THE AMERICAN PHILOSOPHICAL SOCIETY, KTC. TWENTY-FIVE ILLUSTRATIONS. PHILADELPHIA: PRINTED BY C. SHERMAN. 1851. /• fi/ff INTRODUCTION. TABLES of meteorological observations afford but little information and give a very indefinite idea of the changes that have taken place in the natural phenomena to which they relate, even to those who are familiar with them ; they require some elucidation to bring the results at once under the eye, and to the mind : in order to effect this object, a series of illustrations have been constructed, which exhibit all the results of the observations of the Exploring Expedition, at sea as well as in port. I have also deemed it expedient to add a few remarks under each head of observations, pointing out some of the results deducible there- from, as well as giving other information, derived from authentic sources, likely to throw some light upon the climates and their vicissitudes, in those parts of the globe visited by us. On the diagrams, the barometrical observations have been reduced to a uniform temperature (32° Fahr.), and to the level of the sea, and corrected for instrumental errors, as well as brought to the standard of the Royal Society, London, with which they were originally com- pared ; in this respect only they differ from the tables. To each series of observations a diagram is annexed. It was my desire to give all the observations made by the Expedi- tion during the period of our four years' absence from the United States ; but I found it impossible to condense them in such a manner as to exhibit the results without confusion. The Meteorological Journal of the Vincennes has, therefore, been adopted throughout in the body of this work, and the Journals kept on board the other vessels of the squadron, on their separate cruises, have been added in the Appendix. The results are thus made to extend over a large area. To have given them separately, would have been but publishing 2 .T 1 LJ f- vi INTRODUCTION. duplicates, and occupying three times the space they now fill in this volume; and although it might have given a fuller idea of the duties performed by the officers of the Expedition, yet it would have been of no advantage commensurate with the expense that would have been incurred. The Meteorological Eegisters that were kept in connexion with the Expedition at Cambridge, Mass., by Wm. Cranch Bond, Esq., Astro- nomer, Harvard College, and at the naval depot, Washington City, by Lieutenant J. M. Gillis ; with many others obtained through the kind- ness of friends, that were kept at the various places visited by the Ex- pedition, some made by authority, and others by individuals deeply interested in this branch of science, have been incorporated on the diagrams, thus enabling me to make a comparison with the daily results of the Expedition at many places of great interest, particu- larly those on our western or Pacific coast, and others on the eastern, situated in nearly corresponding parallels of latitude. The duty of keeping the Meteorological Journals on board ship was assigned to the medical officers of the Expedition ; those kept at the observatories were superintended by the officers who were from time to time engaged in astronomical duties. In some places omissions will be observed : these have occurred from the unavoidable absence of the officers on other duties, or from accidents to instruments, which could not for a time be replaced. The meteorological instruments used by the Expedition were pro- cured in 1836, from the best makers in England, France, and Ger- many; others were prepared by Fisher, of Philadelphia, with great care and accuracy. They were all compared with the standard, with which they agreed. It was deemed essential at the beginning of the cruise, to insure a uniform mode of observation by all the officers ; the method of procedure was pointed out to all who were to be engaged in the duty, and, it is confidently believed, was adhered to throughout. Books of formulae were prepared for recording the obser- vations. The diagrams scarcely need explanation ; they are of two kinds : those giving the results at the observatory stations will be familiar to all; — the others, exhibiting the phenomena on the passages, are con- structed on maps of Mercator's projection, showing the track of the ships for each day ; lines drawn perpendicular, passing through the figures on the track, will intersect the horizontal lines of temperature, the scale of which will be found on the right or left hand column. INTRODUCTION. vjj The mean daily results of the barometer is given on a" suitable scale above and below 30 inches. The hours chosen for observation were those generally adopted, viz. : 3 A. M., 9 A. M., 3 P. M., and 9 p. M., according to civil time ; when it was deemed desirable, more frequent observations were ordered. At the observatories, hourly observations were made, and throughout the voyage, hourly observations of the temperature of the air and water were taken, both at sea and in port. A thermometer placed at the mast- head was also observed at the hours above indicated ; it was sheltered from accident by a small covering, which did not obstruct the free passage of air : this served to check the results on deck, proceeding either from reflection or the influence on the temperature arising from a crowded ship. The barometer for the use of the observatory was an ivory float gauge, made by Troughton & Simms ; its diameter of tube was O35 in., and its error on the Royal Society's standard -007. This was considered the standard : it continued in use throughout the voyage, and was in perfect order at the return of the Expedition, having been used in the final experiments at Washington. It was read off to thousandth parts. We had several standard thermometers by Troughton & Simms, Dolland, and Jones, of Charing Cross, both for air and water, graduated on metal and ivory to half degrees, and easily read off to tenths; the length of scale. 18 inches; also several self-registering spirit ther- mometers, among them, those of Six. The hygrometers in use were Pouillet (a capsule), Daniels, the silver cup, and the wetted bulb. The Photometer and ^Etherioscope of Leslie were used. The rain gauge was that of Dewitt, a cone of nine inches in height by six at the base ; it was measured by a rod graduated to hundredths. It was placed at the end of the spanker-boom, where it was free from the drip of the sails or rigging. The quantity of water that fell was measured immediately after rain. The force of the wind was noted in the usual way by the different observers. For the sake of space in the tables, the expressions have been changed into numbers. CAPE HENBY TO MADEIRA. — This passage occupied twenty-eight days. The diagram (Plate I., page 18) elucidates the meteorological data, by an inspection of which they will clearly appear; the tempera- ture of the water due to the Gulf Stream will point out its width, and the influence it exerts over the air. The movement of the barometer, as well as that of the temperature, is satisfactorily exhibited in the gale of the 26th and 27th of August, which was encountered on the outer edge INTRODUCTION. of the Gulf Stream. It will be seen we passed without the Gulf Stream, in longitude about 60° west, yet we continued to be carried onward by an easterly current, until we reached the longitude of 45° west. The temperature of the water during this passage between the latitudes of 32° and 42° N. was generally higher than that of the air; the difference in temperature of the ocean on the two sides was nearly 7°, although we had decreased our latitude 4°, and this gra- dually from the United States to Madeira. The mean temperature of the water was 76'8°, and that of the air 75'1°, which will express the standing of the thermometer in the Atlantic within these parallels for the months of August and September. The mean height of the barometer was 30-215, which is higher than it ranged at any other time during the voyage. Easterly winds were found to have a tendency to elevate the column, while those from the western quarter depressed it. The mean degree of moisture on this passage was '666. MADEIRA. — Whilst at Madeira, the mean standing of the barometer was 30-176 in.; mean temp, of the air 74-9°; water 73'6°. We found the height of the vapour plain to be about 4,000 feet above the level of the sea, which, according to our measurements, corresponds with that of the height of the Roche d'Empeiia, observed to be the highest point of cultivation. There is little doubt that the vapour plain must have considerable influence upon the climate of Madeira as well as its productions. In determining the altitudes of this island, an oppor- tunity was afforded us of ascertaining the decrease of temperature as to elevation : the result of simultaneous observations gave for the altitude of Pico Ruivo (6,180 feet), 254-1 feet for each degree of temperature, that of Roche d'Empena (4,100 feet), 384-2 feet, and that of Camancha (2,000 feet), 333 feet. The observations were made between meri- dian and 6 P. M. The degree of moisture at Madeira was '599. MADEIRA TO RIO JANEIRO. — This passage occupied a period of fifty-nine days, including two days' delay at Porto Praya. Between Madeira and Porto Praya (18° of latitude), the water and air increased in temperature 9°, the former being generally two degrees warmer. The trade winds were met with in the latitude of 27° north; previous to which we experienced a strong breeze, whose limit included some of the vessels of the squadron, carrying them rapidly onward, while the others were left for several hours becalmed. These winds are of most frequent occurrence at the outer verge of the trade winds, and particularly on the eastern side of the Atlantic : though no doubt INTRODUCTION. jx often noticed by others, I have nowhere found them alluded to. The direction from which the wind came, in the instance referred to, was northeast, and so brisk as to carry the ship onward at the rate of seven knots. One of the phenomena met with on this passage was the red misty haze so prevalent in this track. The state of the meteorological in- struments under which it occurred was as follows, viz. : barometer reduced to 32°, 3O020 inches ; temperature of the air, 78° ; tempe- rature of the water, 82°; degree of moisture, '706. Wind from the northeast to east-northeast, light and clear over head. During the continuance of the mist a heavy shower occurred, which lasted for an hour ; on its cessation, the dew-point was found at its former standing, but the temperature of the air had fallen 3°. I was at first inclined to believe this phenomenon was the result of the difference of temperature between the air and water, but as I afterwards observed the same haze when there was little or no difference noticed, though the trials were repeatedly made, I cannot impute it to such a cause. The most remarkable circumstance accompanying this mist or haze is its red colour. That which occurred at Porto Praya had a great resem- blance to the " dry fogs;" no particles of matter were observed floating in the atmosphere to produce the red colour. During its continuance the sky is clear, and cirrus clouds are often visible, but the horizon is at all times ill-defined and much obscured; objects are quite indistinct and apparently diminished in size, the effect of the red mist being en- tirely the reverse of what takes place in fog. The cause of this pheno- menon, it appears to me, is to be found in the intermingling of currents of air of different temperatures in the higher atmosphere, producing condensation, which descends, and passing through strata both warmer and drier become again absorbed; hence no deposition takes place, and whilst this condensation and absorption are going on, the pheno- menon is seen. That this is the case I think is proved by the state of the mast-head thermometer, it being invariably found to be some two to five degrees lower than that on deck during the con- tinuance of these mists. The red appearance I think may be accounted for by the refraction and reflection of light : as the sun attains the zenith the reddish tint becomes deeper, but is variable according to ,the angle in which the light falls ; in places it is of a lighter hue, and frequently assumes a patched or mottled appearance. At nightfall the same phenomenon takes place, but then there is a deposition which assumes all the appearances of dew, but totally distinct as 3 x INTRODUCTION. regards the requisites for the formation of dew, as laid down by Dr. Wells. Dew, according to that gentleman, is caused by the following circumstances : — 1st. A fall of temperature in the stratum of air in contact with the soil. 2d. The soil must be previously heated, and the vapours rise, so as to be encountered by a descending current, which brings the vapours back to the earth without the air being saturated. 3d. After sunset, when the weather is calm and serene, the soil radiates heat, and its temperature descends several degrees below that of the contiguous stratum of air; and this causes the deposition to take place. 4th. The fall of temperature always precedes the formation of dew. 5th. Dew is deposited more copiously on bad than on good con- ductors of heat. According to our observations : — 1st. Dew is not accompanied or preceded by any fall of temperature near the surface. 2d. The deposition even takes place before sunset, and very fre- quently during a brisk breeze, the sky being clear, and stars visible. 3d. The temperature never descends or changes, and in all cases has been found two or three degrees above the contiguous air. 4th. There is no fall of temperature in the stratum of air in contact with the ocean. 5th. All substances, whether good or bad conductors of heat, are equally covered with dew or the deposition. It will thus be seen that the requisites for the formation of the phenomenon of dew, according to Dr. Wells's theory, are totally wanting in the production of the same phenomenon when it came under our observation. It is not my wish to controvert or deny the truth of Dr. Wells's beautiful theory, so long received as the true solution of dew, but it is plainly deducible from the facts stated, that dew is otherwise formed, or that which we have witnessed is a totally distinct phenomenon, as far as its formation goes, or that there are two distinct and nearly opposite modes in nature of producing the same result. The theory of the formation of dew by Dr. Hutton appears to me to account for the phenomenon as witnessed by us, and to establish that the same causes produce it as go to the formation of the mists before referred INTRODUCTION. xj to, with this difference, that the precipitation in its descent does not become again absorbed. The experiments I have occasionally been able to make on land, relative to the formation of dew, have been but few during the voy- age, but I feel satisfied that the same phenomenon occurs without a change taking place in the temperature of the soil, particularly in low latitudes, and that the deposition is attributable to causes operating in the atmosphere above, as before indicated; and fully believe that these depositions are far more beneficial to vegetation, and conse- quently to the agriculturist, from the fact that the soil does not undergo any change as to temperature that would serve to check growth, at the same time that it enjoys the beneficial effects of the moisture. Between the latitudes of 5° and 9° 30' north, we experienced the equatorial rains : the amount which fell in ten days was 6'15 inches, its temperature 69° to 72°; the greatest fall in twenty-four hours, 1'95 inch. The variable or rainy zone, at the time we crossed it, ex- tended from 4° to 12°, north latitude, which gives it a width of five hundred miles. The maximum heat of air and water occurred in 8° 30' north, and in 24° west longitude ; which corresponds very nearly to the centre of the belt. We were detained within it twenty-three days, during which time the mean standing of the barometer was 29-987 inches, and the mean temperature of the air 79-6°, and that of the water 82-07°; the degree of moisture -734; the winds were light and variable, generally from the northward and westward, though inclining to calms; the movement of the upper stratum of clouds was to the westward during our traverse across the zone. On the equator, the oscillations of the barometer were found to cor- respond to 3 A. M. and 3 p. M., 9 A. M. and 9 p. M. ; the variation was equal to -1 of an inch ; this is the result of hourly observations for a period of forty-eight hours ; the actual observations have been already pub- lished, and will be found in Appendix XVI., Vol. I., of the Narrative. The southeast trades were entered in 3° 50' north latitude: these winds, at the season of the year we passed through them, were found to increase as the sun was approaching the meridian, and to continue until the afternoon, when they decreased until towards evening, after which they again increased until towards daylight. The weather from the latitude of 3° north is generally fine throughout the year. A variation in the monsoons is experienced as the coast of Brazil is approached : they blow from October to March from the northward xji INTRODUCTION. and eastward, and from April to September from the southward and eastward. These winds appear to exercise much influence on the cli- mate of Brazil. EIO DE JANEIBO — Our observations at Rio were continued through a period of forty-four days. The highest range of temperature we ex- perienced was 93° Fahr., and the lowest 68° — the mean being 77-5°. The mean barometer, reduced to 32° Fahr., 29-899 inches; the oscilla- tion of the mercurial column was '710 in. The tropical hours were for the minimum at 3 A. M. and 3 p. M. ; the maximum appears to have been deferred until between the hours of 10 and 11 A. M. and P. M. The degree of moisture '796. The mean temperature of sun's rays 83°, the maximum being 117°, while the minimum was but 70°. The mean annual temperature, as determined by the thermometer placed in a well twelve feet below the surface, on the island of Enxados, was 75'98° Fahr. The mean annual temperature, as determined by J. Gardner, Esq., which he obligingly furnished me, the day observa- tions for nine years, was 77-01°; the highest range of the thermometer was 93°, in the month of February, and the lowest 64°, in the months of July and August. From these data Rio Janeiro does not appear to possess a warm climate, yet it seems so to the feelings; the heat during the morning hours, between the times of the land and the sea breezes, is excessive. The range of the photometer while at Rio was between 5° and 100°. The climate is a very equable one, as will appear by the mean monthly temperature for six years, represented on the diagram, Plate III., page 74. The rains occur in every month in the year, and there is very little difference in the number of rainy days ; the greatest quantity, how- ever, appears to fall during the months of December, January, Feb- ruary, and March. There has been no measurement of the annual quantity of rain, that I am aware of. During the summer months the rain usually falls in thunder-gusts, which arise in the southwest ; these occur in the afternoon, between the hours of four and six, are very violent, the rain falling in torrents. The wind at Rio generally alternates between the land and sea breezes, which both tend to diminish the heat of the climate. On the coast of Brazil, the tropical or northeasterly monsoon blows during the summer months, viz., from October to March, and the southeasterly monsoons during those of the winter. These may be said to cause the vicissitudes of the climate. During the latter season, gales of wind prevail from the south. We cannot fail to remark, on inspecting the diagrams on Plate III., page 74, INTRODUCTION. the regularity with which the air and water have followed each other in temperature, leading to the belief that the former is influenced by the latter in the extensive estuary which forms the Bay of Rio, the lines indicating the mean daily result being almost parallel to each other. The sea-breeze tends very much to moderate the heat of the climate. Its setting in during the time of our visit was extremely irregular, sometimes not until 3 p. M., but it generally commences between 9 and 10 o'clock in the morning, and its average duration is from seven to eight hours; during the night a land-breeze relieves the heat of the climate : the hottest part of the day is the interval between these two winds. The fair days in the year are about two-thirds ; one- sixth are cloudy, and a sixth rainy. During the summer months little dew is said to fall, but in the winter it is reported as occasionally very copious. EIO JANEIRO TO BIO NEGRO. — The route pursued was about one hundred miles from and parallel to the coast of South America. By referring to the diagram on Plate IV., page 94, it will be seen that great and sudden changes took place in the temperature of both air and water between the latitudes of 36° and 40°, which was in the immediate neighbourhood of the River La Plata, and whilst crossing its mouth. This temperature may mark out the width of the mouth of this river, but I am inclined to consider it as the effects of a cold current from the south setting in on the coast : the breadth of this space in a line parallel with the coast was three hundred miles. I have been unable to ascertain the temperature of the waters of the La Plata during the month of January, but believe it to be higher than the point to which the temperature fell. The winds during our voyage were light, from the southward and eastward, and the weather generally fine. The thermometer had fallen 11° in these 18° of latitude, one-half a degree for each degree of latitude. The mean barometric pressure had decreased -115 in. EIO NEQEO. — Our stay at the mouth of the Rio Negro (which is the northern boundary of Patagonia, lies in latitude 41° south, and is the most southern of the former Spanish settlements on the eastern side of South America) was too short to obtain any series of observations which would increase our knoAvledge of the climate ; but as the mete- orology of this part of the world is extremely interesting, and but little known, I deem it advisable to give some of the results obtained during the time of our detention there. The mean temperature of the air in the roads was 66'4° Fahr., that 4 xiv INTRODUCTION. of the water 67'3°; the mean standing of the barometer 29-784 in., and the mean degree of moisture -798. The winds were variable, generally light, from the east or seaward ; with these the barometer rose, while those from the southwest depressed it. The range of the photometer was from 20° to 93° during fine weather and a clear sky. A thermometer placed three feet below the surface for several hours showed 75-5°; another placed in the sand rose to 114°y and continued so from 9 A. M. till noon ; one covered with wool, a foot above the soil, stood at 90°, while an uncovered one similarly situated showed 82'3°. During these trials the degree of moisture was '854, the wind moderate from the northeast, and the sky quite clear. The temperature of a cave, inclined about thirty-five degrees to the horizon, and twelve feet deep, with south exposure, situated in a bluff of soft gray sandstone, having a perfectly horizontal stratification, was 70° Fahr. : although this affords but an approximate result for the mean temperature, yet it indicates a very high mean annual temperature for the latitude. That such is the case seems very probable from the accounts derived from the most intelligent of the inhabitants at the Rio Negro on the east, and San Carlos de Chiloe on the west, lying nearly in the same latitude, and which are the most southern points where settlements have been formed : at both places snow and ice are seldom seen ; they experience no severe cold ; but frosts are frequent during the winter months, from May to October, when gales of wind are experienced from the southward and eastward. The great peculiarity of the climate of Patagonia is its dryness. The pampas are destitute of verdure, and unfitted for the abode of civilized man, except in a few localities where the rivers which flow from the interior enable cultivation to be carried on by irrigation. The situation of the southern part of South America, which includes Patagonia and New Chili, is peculiar, occupying a strip of continent only three hundred miles in breadth, lying between the two great oceans, the coasts of both sides trending nearly north and south, a lofty range of the Andes extending throughout its entire length and covering one-fifth of its width ; with the wide and barren pampas on the east, and the narrow and luxuriant forests on the west, rising even to the limits of eternal snow ; the former enjoying a clear and cloudless sky and a dry and temperate atmosphere, while the latter is subject to vio- lent gales of wind from the westward, accompanied by heavy rains, producing a redundancy of moisture and almost constant cloudy weather, yet with a like temperate climate. The cause of these INTRODUCTION. xv opposite effects is believed to be one and the same. The westerly winds which prevail on the Pacific coast, after being deprived of their moisture by condensation on the Andes, rush onward towards the pampas to supply the partial vacuum produced by the heated surface of the plains ; being destitute of moisture they absorb it from the soil, rendering it dry and unproductive, and causing the exces- sive evaporation that is experienced in the salt lakes of the interior, which are said to form a crust of salt of considerable thickness on their surface in twenty-four hours. BIO NEGRO TO ORANGE HARBOUR. — The passage from Rio Negro to Orange Harbour was made in the month of February. In the lati- tude of 44° south the temperature of both air and water fell 11°, which was in part owing to our having entered the cold currents from the south : the waters along the coast are of a higher tempe- rature, which may be owing to the prevalence of northerly currents, or the influence of the tides. A farther depression of the barometer took place, with an increase of the degree of moisture. The winds and changes of the weather had become sudden, and everything betokened, as we approached Cape Horn, that we had entered an inclement and fickle climate. Refractions, and the phenomena of halos, parhelias, &c., were frequently seen ; some of these have been previously described in the Narrative of the voyage, Vol. I., page 112, (4 to. edition.) The weather in the immediate neighbourhood of Cape Horn we found delightful, with light easterly winds, which, except at the periods of the equinoxes, are uncommon. The winds from the time of our leaving the Rio Negro were from the southwest, and at times blew in violent gales of short duration, accompanied with sleet and snow, although it was midsummer. ORANGE HARBOUR. — Orange Harbour is situated within the collection of islands which form the southern point of the continent, and thirty miles to the northward of Cape Horn, on the west side of the Bay of Nassau, which is surrounded by undulating hills, six hundred to one thousand feet in height, covered with a dark forest of birch, beech, willow, &c. The mountains to the north are seen capped with snow. Many of the high peaks are entirely destitute of vegetation, exhibiting only a bold projecting outline of bare rocks. The soil is found to be saturated with water, and covered with a growth of mosses, even on the highest hills. The face of the country indi- cates pretty accurately the nature of the climate. Our stay was from the beginning of February till the latter part of April. XVI INTRODUCTION. The great peculiarity of the climate is its moisture. It may truly be said that there is not a day without some deposition in the form of either fog, mist, rain, snow, or sleet. The diurnal oscillations of the barometer were found to be -175; its extreme variation 1-420 in., its mean standing being 29 '545 in. At the time of the autumnal equinox of the southern hemisphere, the oscillations of the barometric column reached '638 above its mean standing. The climate is not a cold one : the temperature during the latter part of our stay was pro- bably not far from the mean annual temperature, viz., 46'7°, and its mildness may be accounted for by the quantity of moisture which exists : the mean degree of moisture we found to be '907. The daily range of the thermometer is small, seldom more than 10°. The sun exerts little influence, the sky even in the finest days being for the most part overcast. The temperature shown by the thermometer freely exposed to the sun gives a difference of 7° Fahr. The mean temperature of the water was 48'7°. This would indicate a higher mean than the air; but it must be recollected there are influences existing beyond the limits of this locality, in the form of currents, which may bring the warmer or colder waters within the bays of Tierra del Fuego : such is probably the case. It will be seen by the diagram on Plate V., page 126, that the water maintained a higher temperature than the air, although it had a gradual decrease of 9° Fahr. as the season advanced. The prevailing winds were from the southwest : we had thirty-four days from that quarter, four and a half from the northward and westward, four and a half from the northward and eastward, and one and a half from the north. Nothing can afford a stronger evidence of the nature of the cli- mate, than the fact of six gales of wind having occurred within the space of twenty days ; they were all of extreme violence, though differing in duration, the shortest being but nine hours, whilst the longest was more than twice that time. On Plate V. there is a small diagram of the movement of the barometer during these gales, veri- fying the remarkable fact before mentioned, that a rise of the column is coincident with the beginning of a gale ; and it may be farther remarked, that, so long as the mercury is descending, fine weather con- tinues. The thermometer also seems in some measure to indicate the coming gales by a sudden fall ; this, however, may be owing in part to the change in the dew-point, which was observed to fall previous to these occurrences, showing greater evaporation and consequent cold. INTRODUCTION. xvii A similarity of movement in the barometer and thermometer is satis- factorily exhibited on the diagram of our observations at this place. Rain fell during thirty consecutive days to the amount of 8'26 in. ; this was the season in which there is least. The greatest fall in twenty-four hours was 1'08 inches. The opinion has been and is still entertained, that the temperature of the southern hemisphere is much lower than that of the northern ; if this opinion is founded on the standing of the thermometer, I have little doubt that it will prove erroneous, and that the mean annual temperature will be found higher in the southern than the northern hemisphere, while the difference between the maximum and minimum is probably much less. That the cold of winter cannot be so great is evident from the habits of the natives of Tierra del Fuego, who use little or no covering throughout the year. I may also adduce the standing of a self-registering thermometer, that was left by Lieute- nant Kendall, of H. M. S. Chanticleer, at Deception Island in 1829, which when examined thirteen years afterwards was found to have fallen only to — 5° Fahr., a much less degree of cold than it would have shown on the parallel of 63° north latitude. CHANGE HABBOUB TO VALPAEAiso This passage was made in the months of April and May : it was a boisterous one, and occupied twenty-three days. The extreme latitude we reached was 58° S. ; the lowest temperature of the air was 37°; the water 4° warmer. The .mercurial column continued to descend until we reached our most southern point, then it as gradually rose without much varia- tion, until we had attained the latitude of 43° south, and passed through the stormy latitudes, which are comprised between the forty- third and fifty-second parallels of latitude. Our distance from the coast was about two hundred miles, and our cpurse parallel to it. The winds we encountered were violent from the northwest to south- west, which are the prevailing winds on the west coast of South Ame- rica, before spoken of as being accompanied with much rain : we had but little rain, though the mean degree of moisture was '881. The parallels of latitude in which these violent winds from the southwest and northwest constantly blow are well known, but their extent in longitude is as yet undetermined; yet there is very little doubt that they have their limits, and it is believed that they extend only a short distance to the west in the great basin of the Pacific, as they are not experienced to the westward of 90° west longitude, about five hundred miles from the coast. How much their direction, velocity, and bois- 5 xviii INTRODUCTION. terous character are due to the influence of the neighbouring continent, it is impossible to conjecture, but it appears very reasonable to suppose that the peculiar formation of this part of South America, already referred to, may exercise sufficient influence over the aerial currents to cause the effects we experience in these latitudes. If condensa- tion and rarefaction are continually going on over a large surface, we see sufficient cause why these currents should not only prevail in the directions indicated, but that they should continue to keep up the same efforts to restore the equilibrium which is being constantly destroyed, and the more rapid the action is on the one hand the more violent it would be on the other. That these winds are the most boisterous during the summer of the southern hemisphere, we believe is generally admitted : such has been the result of our inquiries. On arriving at the forty-second parallel, we were met by the northerly monsoons of the coast of Chili, which continued without cessation until we reached the latitude of 36° south, when we encoun- tered a gale, during the continuance of which the barometric column had a downward tendency, and did not begin to rise until the height of the gale was over. Afterwards, we were favoured with the southeast trades. This length (nine days' duration) of the northerly monsoons at this early day (12th May) was unlocked for, but from information I received, such storms frequently occur from April to September. After our arrival at Valparaiso, I found that light north winds had prevailed there, with calms and fog, which latter is a common accom- paniment. It has been remarked above that a large amount of rain falls on the west coast of South America to the southward of the for- tieth parallel, notwithstanding the atmosphere is not near the actual point of saturation : the fact that the crops are gathered in a wet state, and spread over the floors of the houses to be dried and cured, is con- clusive that such is the case, and that the process of evaporation must be extremely rapid. Captain King, during his stay at San Carlos in 1829, gives the standing of the barometer reduced to 32° : for Septem- ber 30-061, October 29-979, November 29-898 ; the mean temperature 50-5°; the quantity of rain 10-79 in., and the degree of moisture -833, and this was considered the fine season. VALPAEAISO Our arrival at Valparaiso was in May, the last autumnal month of the southern hemisphere. Our stay was limited to a few weeks. Through the kindness of Mr. Robert Heath, of Val- paraiso, we were allowed to take a copy of his meteorological observa- INTRODUCTION. xjx tions made at the Bolsa (Exchange), for the two years preceding our arrival. The observations of Mr. Heath have been reduced to our standard for temperature, &c. I was gratified to find that by a compa- rison made with that of Mr. Pentland the year previous, Mr. Heath's instrument showed the same deviation as with ours, when reduced to the Royal Society's standard. I have given the results of Mr. Heath's observations on Plate VI., page 138, where the tri-monthly means are shown, and also the days of the month on which the maximum and minimum occurred ; it will be seen that the extreme annual range of the thermometer is from 50° to 86°, a difference of 36°; that the mercurial column has a higher range during the winter and spring months than it has in the summer and autumn, which seasons correspond with the north and south monsoon. It is to be understood that these observations do not include the night hours, and but eight hours of the twenty-four, viz., from 8 A. M. till 4 p. M., at which times and at noon the observations were made. It certainly would have been desirable to obtain a series including the night hours also; but these day observations nearly correspond to the maximum and minimum hours, and, although imperfect, they may be regarded as throwing some light upon the movements of the mercurial columns at Valparaiso, until more perfect ones are made. According to them, the mean annual temperature is 66-l° Fahr., and the mean standing of the barometer 29-987 in.; greatest oscillation -570. Chili occupies but a narrow strip of the western side of the vast con- tinent of South America, extending through twenty degrees of latitude. It has the lofty range of the Andes as its eastern boundary, and nu- merous spurs of great elevation intersecting the country in many parts, which, with the cold waters flowing along its shores, must materially affect the climate in particular localities. The climate of Valparaiso cannot be taken as any criterion by which to judge as to that of the country ; indeed it may be remarked that what may be descriptive of one section will not by any means accord with that of another ; from its extreme southern to its northern point the climate differs very materially. Throughout the whole length of the coast, a distance of over one thousand miles, and this trending north and south, the thermometer varies only a few degrees : the great and remarkable variation is in the degree of moisture, for while the extreme south has constant rains, the extreme north is totally destitute of moisture, the country incapable of cultivation and quite a desert ; between the two we have a constant gradation. The cause seems to be obvious : XX INTRODUCTION. where the ocean or westerly winds prevail, they deposit their moisture ; these do not extend farther north than the Rio Maule, in latitude 35°, from which point the monsoons blow parallel with the coast; during the southern summers they come from the south, while those from the north prevail during the winter; with the former the weather is clear and the sky generally cloudless, but the latter are attended with rain, mist, and fogs. These monsoons are circum- scribed within narrow limits. The south one rs sometimes confounded Avith the southeast trades, from which it differs very materially in its direction, and, as I before remarked, half the year it is intermitted. The southern monsoon is a dry wind, and its daily duration is generally confined to five or six hours, from 11 A. M. till 4 p. M.; a calm then succeeds, and towards morning, in this season, the land wind is felt with almost the same certainty. The winter monsoon blows moderately from the north and northwest, has a high degree of moisture, and at times violent storms take place. Although the winds are the great agents in producing the changes in this climate, there are other causes which also exert their influence. As far as the temperature along the coast is concerned, its small variation may readily be ascribed to the south polar or Chili stream, which sweeps throughout its whole extent. At Valparaiso, in the latitude of 33° south, we found its water at 56° Fahr., and, from many observations I have had access to, it varies little from this temperature throughout the year. The monsoons are found to prevail as well in the interior as on the coast, and have the same characters; and to their influence in like manner it owes its variation of climate. During the summer months, the sky is almost cloudless throughout the day, and especially so at night, when it is calm and brilliant; no rain falls, and little dew. In the valley of the Maypo, they cultivate by irrigation; and, were it not for this, Chili would be an arid and barren waste. What seems remarkable, the dryness of the climate is observable in the highest ridges of the Andes, as well as in the valleys or plains. The lofty ridges in the interior, for the greater part of the year, have a distinct and well-defined outline, resulting from an absence of moisture ; and, from a like cause, the character of the vegetation is thorny. The rainy season throughout Chili, north of the Rio Maule, is in June and July, when it rains in torrents. I have no account of the quantity which falls ; it lasts at times for a fortnight, raining violently and almost without cessation : the beds of rivers that were dry become INTRODUCTION. XXJ swollen, and the whole country is rendered impassable for a time. These rains take place when the northerly monsoon returns charged with the vapours from the tropics, which coming in contact with the cooler atmosphere surrounding the highlands and mountains of Chili, condensation takes place, and produces the violent rains during this season. But, as this cannot take place on the northern coast and its adjacent country, owing to the temperature not being low enough, rain is rarely if ever experienced there. The variations which took place at the time of our visit will be seen on the diagram before referred to. Our observations show a barometric oscillation of '530, which appears to be about the extreme range throughout the year ; its mean standing we found to be 29'896 inches. The temperature of the air varied from 65° to 46°; mean temperature 55'2°. That part of Chili still inhabited by the Arau- canians in the south, is said to possess a mild and equable climate : it is considered the most fertile, having an abundance of everything, and enjoying a happy mean between the extremes to which the other parts are subject. Sun's radiation, by means of twenty-eight observa- tions, was 68'4°, shade 58'3°, difference 1O1° ; greatest difference in sun 39°, the least 2°. During our stay, the weather was for the most part overcast both night and day ; the observations were taken when it was clear. VALPARAISO TO CALLAo. — In our passage from Valparaiso to Callao, at about one hundred and twenty miles from the coast, we passed beyond the influence of the northerly monsoons into the southwest wind, and then into the trades, in latitude 28° 30', which is believed to be their southern limits at this season of the year. On several successive days the wind veered even to the northeast for a few hours; as we approached the coast of Peru, it became more southerly and moderate. The temperature of the air increased but 7° ; that of the water, only 5°. It will be observed, by an inspec- tion of the diagram on Plate VII., page 158, that when we were the farthest from the coast, the temperature of the water rose several degrees, proving satisfactorily that we were without the limits of the Chili current, and that on nearing the coast of Peru we again entered it. The mean height of the barometer had increased -087 in the 21° of latitude. Although the sky was much overcast, we had no rain : the degree of moisture was -949. CALLAO. — It was the middle of the month of June when we 6 xxii INTRODUCTION. arrived at Callao ; we remained there until the middle of July, part of which time our observations were made at the Island of San Lorenzo, which forms the western side of the bay. This was the season of winter, the sun being to the north of the line, and the time of the year when the heavy mist (garua) prevails, which almost screens the heavens from view. This is variously accounted for. Throughout the year the wind blows almost constantly from the southward, although at diiferent seasons it varies very much as to strength : during the spring and summer months, from November till May, it blows moderately without intermission, whilst in the autumn and winter it is, though generally stronger, often interrupted, when light airs succeed from the north ; on their occurrence the " garua" is immediately formed, and towards evening a heavy deposition takes place, which leads to the conclusion, that the returning warm moist current from the north encountering the cooler ones from the south causes precipitation. The recurrence of these circumstances always produces the same effect. Whilst the south winds prevail conti- nuously, the whole coast of Peru enjoys a clear atmosphere and fine weather. In winter the sun has seldom power enough until near mid- day to dissipate these mists, which renders the climate during the winter season damp and cold, prejudicial alike to comfort and health. The mean annual temperature at Lima is placed by the best autho- rities at from 60° to 85° Fahr. I am not aware that any recorded observations of the barometer have been made throughout the year, but the mean standing of the mercurial column during our stay was 29 '9 83, and its greatest oscillation '200 : the maximum and minimum temperature was 56° to 82° Fahr. ; mean temperature during our stay, 63-3° ; mean water 59'8°, minimum 56°, maximum 63° ; solar radia- tion 83-1° sun, air 73-6°, difference 9'7°; 35 observations. Photo- meter 93° and 19° ; 8 observations: the degree of moisture -922. From the observations made during our visit, we found the vapour plain on this coast to be elevated above twelve hundred and twenty feet. Below this point vegetation is confined to the winter months, unless moisture is supplied by artificial means. Without the tropics, where the vapour plain exists, it protects vegetation below it, but within, the reverse seems to take place : in the first case, we ascend from luxu- riant vegetation to barrenness; in the latter, from an arid, barren waste to some of the most productive and fertile portions of the globe. The low temperature of this part of Peru is to be ascribed more to the influence of the temperature of the ocean, than its proximity to the INTRODUCTION. xxjjj Andes. The prevailing winds pass for a long distance over the sea, and serve to modify the heat of a tropical climate. The small diagram (on Plate VIII., page 188) of the mean daily temperatures at Callao, will show their variations from each other and from that of the water of the bay. CALLAO TO TAHITI. — This route was sailed over during the months of July and August, and between the parallels of 13° and 18° south latitude. The temperature of the air and water changed and the weather became fair when we had reached a distance of one hundred and twenty miles from the coast; the former from 63° to 76°, and the latter from 66° to 78°, until we entered the Paumotu Group. We carried the southeast trades until we were in latitude 17°, and had reached the longitude of 110° west, when they left us, and the wind changed to the west, southwest, and northwest. This interruption continued for several days, with an atmosphere loaded with vapours, an overcast sky, and the barometer standing -100 higher : the diagram (Plate VIII., page 188) will exhibit these variations. The wind afterwards could not be termed the trade wind : though mostly from the eastward, it frequently veered to the southwest, from which quarter the upper stratum of clouds was passing rapidly : these continued until our arrival off Clermont de Tonnerre, the most eastern island of the Paumotu Group. From our observations, it appears that the limits of the trade winds towards the central part of the Pacific, do not extend the same distance from the equator that they do nearer the coasts. It will be recollected that but a month previous to our passing over this route, we had met with the southeast trades in the latitude of 28° 30' south, near the coast of South America; now, at a distance of two thousand miles from the coast, we had lost them in latitude 18° south, and at the season of the year when they are sup- posed to extend to their farthest southern limit, showing a difference in the distance from the equator of 10° in latitude ; and it will be hereafter seen that beyond the Society Islands it is contracted within still narrower limits, while on the western side of this ocean they have been found to extend to the latitude of 22° south : this gives their line of limit a convex curve towards the equator. The degree of mois- ture which we experienced varied from -701 to '984; mean '873. Solar radiation, sun 95°, air 76'8°, difference 18'2° ; greatest diffe- rence 41°, least 4°. The water throughout was about 4° warmer than the air. xxiv INTRODUCTION. GBOTJP -- The Paumotu Group has two seasons, notwith- standing its very uniform temperature throughout the year, which may be divided into the stormy and fine : the former prevails from November till March, when the sun is vertical, and the temperature has its highest mean; the fine season is from April till October. During the former, violent gales from the west and southwest occur, though the winds blow generally from the northward and eastward, rarely south of the east point, and are accompanied with much rain. These gales, which are frequent, cause a great rise of the waters, which often submerge msiny of the low islands ; on these, numerous evidences are seen of the destructive effects from the abrasion at these times, and I think sufficiently account for the dilapidation which is every- where seen on the west side of the islands throughout the South Pacific. There is no time afforded for the growth of vegetation, be- tween these storms, and often from their violence the debris or soil must be washed entirely away. The southeast trades are prevalent in the fine season, with fair weather for most of the time, though they are subject to severe squalls, which last but a few hours. At the time we passed through this group, we found no ocean current to exist. The mean standing of the barometer was 29-964 inches; the mean temperature during August 79° 33'; the degree -of moisture '877: the temperature in January, 1841, when visited by the Porpoise, was 81 '4°. Although the temperature was so high and without variation, the climate, judging from the healthiness of the natives, and their apparent lon- gevity, is salubrious. The power of the sun's rays, by 94 observa- tions, was 96° sun, 8O8° shade, difference 15'2°; greatest difference 35°, least 1°. The thermometers were exposed on a rack con- structed for the purpose, and as free from the influence of reflecting surfaces as possible : the observations were made at corresponding hours each day, and as much as possible under the same circum- stances. TAHITI. — This island was visited by us in the months of Septem- ber and October, 1839, and February, 1841. The climate of Tahiti is usually spoken of as delightful; but, according to the missionaries and residents, it is found to be very debilitating. The variation of the thermometer is between 60° and 85° Fahr. The mean temperature during our stay, in September and October, was 76'4°, in February, 82°. In the summer months (from November to March) the Tahitian Group is subject to the winds from the northward and westward, which INTRODUCTION. xxv render the climate sultry and hot at that season. The climate may be divided into wet and dry periods : the former includes the summer months, the latter the winter. Although there is but little respite from the heat, the difference of the mean being only 6°, yet the setting in of the southeast trade winds brings fine weather, dissipates the vapours, and clears the atmosphere, and for a time produces an exhila- rating effect, both during the day and at night, from the prevalence of a land-breeze which sets in soon after sunset, and causes the night to be cool and pleasant. No one who has not experienced it can estimate the pleasant sensation this wind produces, scented as it is with all the perfumes of this " queen of the ocean." The variations of the thermo- meter during our stay were only 7° for the air, and 2° for the water; the mean of the barometer 30'083 inches, higher than it stood in the Paumotu Group or at sea. The amount of rain which fell was 4 '2 inches : I was not able to procure any data for the annual quantity, the missionaries who have laboured so long in this field never having attended to any of these interesting results in meteorology. The heat on the western side of the island is much more oppressive during the day than on the east, but less so at night, from a longer continuance and more certainty in the land-breeze coming down from the high mountains. The southeast side has almost constant showers through- out the year, particularly during the season of the trade winds. The degree of moisture obtained from our observations on the north side was '800 ; the result on the southeast side would probably have been greater. Many plants succeed better on the southeast side of the islands ; but from the habits of the natives, the north side being more thickly settled, we might infer that the latter is the most agreeable and salubrious. The vapour plain generally exists at two thousand feet, and it is seldom that the mountains are clear of clouds above this height. The solar radiation was 94'9° sun, 804° shade, difference 14'5° ; mean of 27 observations. While we were making the transit from Callao to Tahiti, the Relief, one of the squadron, was on her passage to the Hawaiian Islands from the same port : a view of the oscillations made by her instruments can be seen by comparing the diagram, Plate XXIV., Appendix, with that of the Vincennes, on Plate VIII. The track of the Relief was not parallel to that of the Vincennes, until she reached the same latitude north of the equator, where it appears that both barometers suffered a depression — that of the Relief the greatest; but although the times were somewhat different, yet about the same meridians they 7 INTRODUCTION. show very nearly the same, both giving satisfactory evidence that as the centre of the great Pacific is reached a depression occurs ; and I take this opportunity of calling attention to it, that from whatever direction this ocean is crossed, a like depression will be shown, as will be clearly pointed out by an inspection of the diagrams exhibiting the results of our observations. TAHITI TO THE SAMOAN GROUP. — After stopping a few days at Eimeo, we passed to the northward and eastward of the Society Group, and thence to the westward, on the parallel of 15° south lati- tude. Even on this parallel the winds proved very light and variable from the westward, and we did not obtain the winds from the south- ward and eastward until we had reached the longitude of 160° west. The length of our passage was fifteen days. The change in tempe- rature was +3-53° in the air and +2'89° in the water; the radiation of the sun, the thermometer similarly placed as in former experi- ments, 98-1°, 81-3°, difference 16-8°, the greatest and least difference being 29'5° and 6-5°; the decrease of the mercurial column when at sea was -133. The wind from the west, as we found it to the east- ward of the Paumotu Group, maintained a high column. The degree of moisture '872. SAMOAN GBOTIP — We remained fifteen days in the harbour of Pago Pago, situated on the south side of the Island of Tutuilla, during which period we had an almost constant succession of strong winds from the southward and eastward, with light rain in showers. The harbour of Pago Pago is surrounded by high hills, and the Peak of Matafoa (the highest point of the island, 2,359 feet in altitude), which con- densed the moisture. When the weather was clear, the vapour plain was seen about 300 feet below the peak, extending on all sides over the island. The difference of temperature on the top of Matafoa was found, when compared with that on the level of the sea, to be 10° less, which gave 230 feet in altitude for every degree of the thermo- meter : the observations were made at 4 o'clock P. M. The mean standing of the barometer at Tutuilla 30'033 inches; whole group 29-946, oscillation '400. The mean temperature during our stay was 80° Fahr. ; the range of the thermometer was 17°, from 74° to 91°. A register kept at this island gave the annual mean as 76°. The trade winds, which come from the southeast, blow about one- half of the year, from April to September. In the months of January and February they come from the northward and westward. The proportion of clear weather to that which is cloudy and rainy, is about INTRODUCTION. XXvii equal. In fine weather, copious dews fall. The climate of Tutuillu is much modified by the overhanging clouds, which shield the harbour and its valleys from the powerful rays of the sun. The trade wind sets in about ten o'clock and continues till sunset. The nights are calm ; at times a faint land-breeze is felt. The rain which fell in eleven days of our stay at Pago Pago harbour amounted to 4-3 inches; the degree of moisture in clear weather '871. The climate of the group is believed to be more moist than that of the Society Islands, and warmer; it was thought the season was earlier, many of the fruits being farther advanced, making full allowance for the difference in time. This we believe may be owing to the extensive area of ocean (equal to 3,600,000 square miles) lying a few degrees of latitude to the north of this group, the temperature of which is several degrees elevated above that of the sea surrounding the Tahitian Group. The extent and situation of this area will be seen on the map which faces the title-page. The climate of this group may be classed as variable ; for one situated within the tropics, it has a great deal of bad weather through- out the year, and during the summer months is subjected almost annually to violent hurricanes. In the winter, from April to No- vember, the weather is more settled, the winds more moderate, and calms often prevail. This group was visited by us in October, 1839, and again in January and February, 1841, which enabled me to ob- tain more accurate information of its climate ; this, however, has par- ticular reference to the island of Upolu, the central one of the group, and to the harbour of Apia, on its north side. The map of Upolu (Hydrography, Vol. I.) will give a correct idea of its size and topo- graphy. Apia is situated, with respect to the trade winds, on the lee, or north side. The mean temperature during our first visit, October and November, 1839, was, air 80'55°, water 82'91°; during the second visit, in February, the air 79'94°, water 82-61°. The tempera- ture on the south side of the island is a degree or two lower. The variation of the temperature was from 72° to 98° ; that of the water 6°; from 80° to 86°. From the register kept by the Rev. Mr. Mills, the missionary at Apia, of which I was permitted to take a copy, the mean temperature for the year 1838 was 79°. The mean solar radiation, sun 103'6°, shade 92°, difference 11'6°; greatest difference 26°, least 1'5°. To the kindness of William C. Cunningham, Esq., H. B. M. Vice- Consul of Apia, as well as Mr. Lundy, of Tutuilla, I am indebted for xxviii INTRODUCTION. information relative to a violent hurricane which passed over this group on the 17th December, 1840, shortly before the arrival of the Peacock on her second visit, in 1841. The following are the material facts, viz. : At Apia, on the 12th, light winds prevailed from the southeast, the upper or cirrus stratum of clouds coming from the southwest. The wind continued to increase until the 16th; at midnight it changed to a heavy squall from the northeast. At 2 A. M., on the 17th, the wind was violent from the southeast, with a copious fall of rain; at 2h. 30m., wind from south-southeast in heavy gusts ; at 8 A. M., a rapid shift to southwest ; afterwards the gale gradually moderated, with the wind from the same quarter. At Tutuilla the storm began at daylight on the 17th, increasing till noon. Wind east-northeast. Half an hour after noon there was a lull of twenty minutes, and then the wind shifted suddenly round to the southward and westward, and blew a heavy gale, which continued till midnight : the morning of the 18th was clear. At both places the gale was most violent just after the change, when houses and trees were prostrated, and great destruction caused to a considerable portion of both islands. The islands of Upolu and Tutuilla lie west-northwest and east- southeast. The eastern end of Upolu and the western end of Tutuilla were the parts that suffered most severely. Over the town of Lione, on the western end of the latter, the centre of the storm seems to have passed ; it swept over it and one or two other villages in its track, levelling all the buildings, tearing up the bread-fruit and cocoa- nut trees, and prostrating a large area of forest trees. This gale, estimating from the time of its sudden changes, was about four hours in passing from Upolu to Tutuilla, a distance of sixty miles; conse- quently its progress was about fifteen miles an hour, in a northwest and southeast direction, having been carried onward by the northwest monsoon, which prevailed at that season of the year. The gale was felt at Savaii, the westernmost, and also, from the reports of the natives, at Manua, the easternmost island of the group. They could give no other facts. The length of the whole group is three hundred miles, which would give the diameter of the storm about two hundred and fifty miles. It is to be regretted that no good instruments were in the possession of these intelligent gentlemen, but such as they had were observed. A barometer in the possession of Mr. Williams, the Ame- rican Consul, which usually stood at 28 inches, at Apia, fell as INTRODUCTION. xxix low as 24 inches; the thermometer at 6 A. M. of the 17th stood at 88°, being nearly 8° above the mean standing of the instrument at that season of the year. In 1849, December 26th, they experienced a severe storm, which continued for two successive days : this storm was not so violent in regard to the force of the wind, but the sea was very destructive, rising high, and it is remarked that islets were raised on the reef on the north side of Upolu several feet above high water mark : the wind blew from the east, and came round to the north and northwest. This gale appears to have been of great extent, for it was felt at both the Society and Hervey Groups. SAMOA GROUP TO SYDNEY, NEW SOUTH WALES We had very fine weather on this passage, until we passed outside of the southeast trades, in latitude 22° south, when the wind changed to the northward and westward, then to southwest, and finally to the northeast and north, as we approached the coast of New South Wales. After we reached the longitude of 175° east, and the latitude of 17° south, the temperature of air and water fell rapidly, equalling one degree of temperature for each degree of latitude, till we reached the parallel of 33° south, and 160° east longitude. The barometer in this passage rose '159 ; temperature of the air fell 12-33°, and the water 13-75°; mean degree of moisture '833. Sydney lies upon the same parallel of latitude with Valparaiso, yet differs 10° in the mean annual temperature. The cause is obvious. The ocean which bounds both coasts has also this same difference : one is washed by a tropical current, while that of the other has a polar stream flowing along its shores. On other coasts where the same causes exist, like results are found : the eastern coast of South America differs from the western to nearly the same amount, and the same might be shown of others, did the space allotted for these remarks permit. In comparing temperatures on the same parallel in the northern and southern hemisphere, some interesting results are obtained. The island of Raratonga, one of the Hervey Group, latitude 21° 14' south, longitude 160° west, has a mean annual temperature of 75-61°. The lowest temperature was 60°, in July and August, the highest 89°, in December, January, and Feb- ruary, differing 29°. Oahu, one of the Hawaiian Group, lies in lati- tude 21° 18' north, longitude 158° west ; the mean annual temperature 75-8° : the highest degree of heat in June, for 12 years, has been 90° ; lowest 53° in January; difference 37°. These are both high islands, 8 XXX INTRODUCTION. situated in mid ocean, and within the range of the trade winds of both hemispheres, which blow at Oahu five-sixths of the year, while at Raratonga they are constantly intermitted, and seldom continue half the year : they exert less influence upon the climate in south than in north latitude. The average daily range of temperature at Oahu is 12°, whereas at Raratonga it is but 5° ; the temperature of the water at the Hawaiian Group is 81°, while that at the Hervey Group is 75° : thus we have two islands nearly similarly situated in geographical position, which we find to differ but 0'19° in their mean annual temperature, 7° in their average daily range, and 8° in their greatest difference. I regret that there has not been any barometric observations made at Raratonga, with which to compare the pressure at Oahu. The above results were obtained from observations taken during the years 1837 and '38, at both places, and are confined to the day observations, viz., 6 A. M., noon, and 6 P.M., at Raratonga, and 7 A.M., 2 P.M., and 10 P.M., at Oahu. SYDNEY, NEW SOUTH WALES. — Our stay at Sydney was from the latter part of November till the end of December, 1839, and the month of March, 1840. The weather, during the time of our observations, was cloudy, with rain, the wind generally from the eastward. The mean temperature for the month of December, 1839, was 66'4°, the extreme fluctuation 27°, and the extreme daily varia- tion 11°. The mean standing of the barometer is 29-940 inches, and its oscillation 1-810 inch; by the records of the Colony, the mean annual temperature is G5'70°. The seasons are considered but two, summer and winter, the former from October to February, the latter from May to September : at Sydney these are marked by the preva- lence of the winds : during the former, the easterly winds blow, while during the latter, they come from the southwest; in March and April, as well as September and October, the winds are variable. The ther- mometer seldom falls below 40°, or ranges above 78° during the winter ; in summer its range is from 54° to 91° : these temperatures only apply to the east coast and to the day hours; therefore, although we have the greatest heat, yet it cannot be considered the lowest tem- perature : ice is seldom seen at Sydney. More recent observations, kept at the South Head, at Port Jackson, make the temperature a little different ; but even these latter observations do not include the most important minimum hour of the night, and are, therefore, still only approximate. At Port Philip, on the south coast, the thermo- meter in the winter descends to 35°, and rises to 65° : in summer its INTRODUCTION. ,,,.,.: •A.A.A.1 range is from 50° to 98°. The winds show a reversed order at these two places : while it blows from the eastward on the east coast during the summer season, it is blowing from southwest on the south const ; and in the winter this is again reversed to south west at the former place, while at the latter easterly winds are experienced ; the cause of this state of things is to be looked for in the extensive arid wastes which exist in the centre of New Holland, and will account for some of the remarkable phenomena which take place in the climate ; perhaps there is none more notable than the excessive droughts which frequently prevail and continue for months ; in other years great floods occur. In the Narrative, Vol. II., p. 168, 4to. edition, I have spoken of the exploration of the country, and the peculiar condition in which it was found by the exploring parties, and to which I would refer for information upon the subject. The quantity of rain which falls is very variable: in 1840, 35-25 inches fell; in 1841, 45 inches; making a fourth more. The rainy season is in April and May : the greatest quantity which has been known to fall in any one day, was 20-12 inches. The degree of moisture, by our observations, was -748. I have before remarked that there is a great difference in the climate of New South Wales, and that every locality has in a measure its own. It is difficult to account for the anomalies that occur in the seasons. The rains that prevail on the eastern coast, are generally brought by the west and southwest winds from the interior, as all the meteorological registers, kept at Port Jackson and Macquarie, prove : these are land winds; yet, at an opposite season, we find these same winds causing the blight that is so much dreaded by the agriculturist, from the want of moisture. In March, the barometer stood at 29-969 in., while the temperature of the air and water had risen from 3° to 4° higher than in December. ANTAECTIC c B u i s E. — This cruise was made during the summer season of the southern hemisphere. The diagram on Plate XI., p. 302, gives the track of the Vincennes, the oscillation of the barometer, and the variations of the thermometer, the mean daily depression of the barometer, or the diminished pressure of the atmosphere within and along the Antarctic continent : the mean pressure was deter- mined to be 29-040 in., its extreme oscillation 1-160 in. The tempe- rature of the air, with but few exceptions, followed that of the water : these exceptions only took place when near large bodies of ice, and which are readily distinguishable on an inspection of the diagram. During a period of 42 days in midsummer, the tempe- xxxii INTRODUCTION. rature was but seldom found above the freezing point of water ; the lowest temperature was 22°. From the low temperature of both water and air, it will be perceived that when ice is once formed, it can seldom be melted while it remains in these high latitudes : this will account for the large masses which are almost constantly accu- mulating from the depositions in the form of snow, sleet,, or fog. The winds which prevailed were from the northwest and south- west, until we had passed to the westward of the meridian of 160° east, when we had a change from the eastward, with better weather. The mean degree of moisture was '890. The photometer was ex- posed for the 24 hours for several days : it fell to 19° for the night hours, and rose to 93° in the day : from this it is evident that the intensity of light in the southern hemisphere is not as great as it is represented to be in the northern. The mean solar radiation was 4 -7° ; the greatest difference between the sun and shade 9°; least 1°. A thermometer placed on the black hammock-cloth in the sun rose only to 3G°, that in the shade being 30°. This shows a remarkable difference in the power of the sun's rays between the southern and northern hemispheres. Captain Scoresby and other Arctic navigators state, that the temperature in the sun frequently rose to that of melting pitch, while it was below the freezing point in the shade. It will be seen, on referring to our first cruise to the south, repre- sented on Plate VI., page 138, in the longitude of Cape Horn, that the same results were had : the barometric column decreased in altitude as we reached the higher latitudes, and the thermometers in the air followed that of the water, until masses of ice intervened. The degree of moisture on that cruise was '935. From an examination of the temperature of the southern hemisphere, I have become satisfied that it is more equable than the northern ; of this we have had many proofs, and the observations I have had access to fully cor- roborate it: the fact of the thermometer having varied but a few degrees during the summer months, the power of the sun's rays not being so great, and the temperature not descending so low during winter, together with a much higher mean annual temperature, and a much less range, all tend to satisfy me that such is the case. In the Narrative, I have mentioned several gales which occurred during this southern cruise : the progress of only one I have been able to trace satisfactorily, in consequence of the four vessels of the squadron having been separated some distance from each other. I have refe- INTRODUCTION. xxxiii rence to the gale of the 28th and 29th January, 1840. The position of the squadron was as follows, viz. : Porpoise, latitude 64° 46' longitude 137° 16' east. Vincennes, " 65 45 " 140 " Flying-Fish, " 65 15 " 150 16 " Peacock, " 61 20 " 154 09 " The Porpoise encountered the gale first ; it began with the wind from the eastward, and veered during its continuance to the south- west by the south ; its duration was eighteen hours." The Vincennes next experienced it, the storm undergoing the same changes as those of the Porpoise; duration eleven hours. The Flying-Fish we find to have encountered it next, the storm coming from the northeast and veering to the southward ; duration twelve hours. The Peacock was the last to encounter it, the storm beginning from the northwest, and veering by west to the southwest, the most violent part of it after its change ; duration was twenty-four hours. The distance of the Porpoise from the Vincennes was about 60 miles, which it passed over in 3 hours ; between the Vincennes and Flying-Fish 260 miles, which it traversed in 13 hours; and the dis- tance between the Vincennes and Peacock, about 400 miles, — this space was passed over in 21 hours, which gives its rate of progress about 20 miles an hour, and its track from west-southwest to east-northeast. The centre of the storm must have passed between the vessels ; the Vincennes, Porpoise, and Flying-Fish being to the south, while the Peacock was to the north : this is known by the wind having veered in opposite directions during the changes that took place while it continued. SYDNEY TO NEW ZEALAND — This passage was made in 13 days, in the month of March. By the diagram, Plate XII., page 330, it will be perceived that our route was nearly on the parallel of Sydney, and that the temperature of both air and water was several degrees higher than it had been in a lower latitude in the month of November, illus- trating the influence of tropical currents between New Holland and New Zealand during the summer months. The winds, after leaving the coast, were quite variable, seldom remaining over a few hours stationary. As we approached New Zealand, they were more constant from the southwest; the temperature of the air varied between 64'4° and 71'6°, that of the water between 68° and'72'5°; the oscillations of the barometer were '420 in.; the rise of the mercurial column taking place with northerly winds, whilst it was depressed with southerly 9 XXXIV INTRODUCTION. ones. The degree of moisture -816. We had generally a cloudy and overcast sky, with very moderate winds. NEW ZEALAND. — The observations at Bay of Islands, New Zealand, were during the months of February and March, 1840. The varia- tions of the mean daily temperature are shown on the diagram, Plate XII., page 330. The climate of New Zealand, although changeable, is more equable than that of New Holland. The mean temperature was 61-3°, the maximum 73°, minimum 52°. The prevailing winds are from the southeast and west; the former are attended with rain. May and June are the rainy months. There is usually a difference of 20° between the temperature of the day and night. The degree of moisture '772. The mean standing of the barometer was found to be 30-004 inches, and the temperature of the water 66-37°. The climate of New Zealand is thought to be better adapted to the European con- stitution than that of New Holland. Droughts are never felt in any excess. These islands are in the track of the severe hurricanes, which occasionally pass over them, particularly the northern part near the Bay of Islands. One of these occurred during our stay ; it happened on the 29th of February and 1st of March, 1840. For the development of this gale I am indebted to the inquiries of several gentlemen of the Expedition, who were at the Bay of Islands when it occurred, and to the kindness of the masters of the vessels who were caught in it. We have five positions where observations were made, three to the north, and two to the south of its track, viz. : at the Bay of Islands, on board the Brigs Victoria and Camden, H. B. M. Ship Herald, lying in the River Thames, and the Flying-Fish, one of our squadron; their relative position will be better pointed out by their latitudes and longitudes, which were as follows, viz. : Camden, ... 31° S. 174° 07' E. Victoria, 33° 30' S. 171° 50' E. Bay of Islands, 35° 17' S. 174° 07' E. H. B. M. Ship Herald, ... 36° 49' S. 174° 43' E. Flying-Fish, 40° 30' S. 178° 30' E. From these positions we ascertain that the storm had a diameter of five hundred miles, from the latitude of 31° to 40° 30' south. We also observe that its track was south-southwest, veering as it progressed, to southwest, and that its velocity was equal to twenty miles per hour. Its centre passed just to the southward of the Bay of Islands, at which place there was a calm of ten minutes, when the storm recommenced with equal violence from the opposite quarter ; INTRODUCTION. XXXV the trees that were prostrated at the Bay of Islands were found lying with their tops to the northward. The gale came on with the wind from the southward and eastward at all the stations, — this was nearly at right angles to its actual line of movement : the veer- ing of the gale was from left to right. It was one of the most de- structive that had occurred at New Zealand, the water rising to a great height, and overflowing a part of the island which had before been thought beyond the reach of the sea. The lowest standing of the barometer on board H. B. M. Ship Herald was 28-75 inches, when the gale was most violent. The change of wind took place at 2 A. M. of the 1st of March, and on board the Flying- Fish it was at its height at 3 A. M. Throughout the gale the thermometer did not descend below 66° Fahrenheit, the temperature of the surrounding sea. On our passage to Tonga, one of the Friendly Islands, we did not enter the trades until we reached the latitude of 24° 26' south, when they blew from the east. The barometric column again decreased •139 in., while the temperature of the air increased 13-3°, and the water 9-7°. Tongataboo comes under the class of low coral islands, but its cli- mate is dissimilar ; it is more humid, and the heat more oppressive. The daily transitions from heat to cold arc much complained of, though we found but 8° difference in the temperature. The dews are remarkably heavy, which may account for the feeling of cold at night; they are said to render the climate unhealthful. The mean temperature of the air, during our stay of ten days, in the month of April, was 79-05°, that of the water 79-28°; the barometer stood at 29-808 in.; the degree of moisture '893. Hurricanes are frequent in this group. The months from Novem- ber to March are those in which they occur. According to the accounts given me, these begin with the wind at northwest, go round to the eastward, and end at the southeast. Sudden changes during the height of the gale are experienced, and trees are prostrated with their tops in all directions. It appears that the progress of these storms is from the northeast to the southwest, corresponding to what we found to be the case at New Zealand, and nearly at right angles to that before described at the Samoan Islands. The courses of these gales having been well ascertained, we must conclude that the paths of these storms are deflected, somewhat like those of our own hemi- sphere, only in a contrary direction, moving from the northwest to the southeast in the lower latitudes, and thence passing to the higher latitudes by a course towards the southwest. The same gale at the xxxvi INTRODUCTION. Friendly Islands is seldom felt at the north and south islands, but the islands lying between the two rarely escape : this is another proof of the direction in which these storms move, and the fact that we have no accounts of the same gale having been felt before or after at the Feejee Islands, lying west and northwest of the Group, would seem to confirm the evidence that the directions across the Friendly Group are from the northeast to the southwest. FEEJEE ISLANDS. — We were but two days making the Feejee Group, with the trade wind from nearly east, and an overcast sky. The islands lie nearly west of the former, distant about 300 miles. The position we occupied, was at the island of Ovolao, where we re- mained for 48 days, during the months of May and June, the greater part of which time the observations were made at the Observatory, on the eastern side of the island. The island of Ovolau rises very pre- cipitately to the height of 2060 feet. During our stay, the weather was fine and the winds moderate and variable, prevailing from the eastward for most of the time. The temperature of the air and water varied, the former from 60° to 94°, and the latter from 78'3° to 81°, the mean temperature of the air 77'81°, and the mean standing of the barometer 29-997 inches ; the greatest oscillation of the barometric column '4 20 in: the rise of the column is produced by southeast winds, while it falls with those from the north and west. The weather is generally clear, except when the southeast winds blow strong, when the atmosphere becomes hazy. The height of the vapour plain was found to be 1900 feet above the level of the sea. It will be perceived that the range of the thermometer is greater than at Tonga. The summer months, from October to March, are considered the worst period of the year, when the northerly and westerly winds are expe- rienced, and at times severe storms pass over the islands. The winter months, from May till September, are considered the finest; then the winds prevail more constantly from the southeast ; they blow at this time much fresher. The climate has a general resemblance to that of Tahiti, and the mean annual temperature very nearly corresponds. At the Feejee Islands it has a greater range. During our stay in the Group, stormy weather occurred but once, when the thermometer fell to 70°, the wind from the southeast ; the barometer rose at this time •145 in. above its mean standing. This eifect upon the barometer excited my attention, as I had frequently observed it before, when in the vicinity of high land, and on the side of it which is exposed to the southeast trades. A sufficient cause for it may be found in the obstruction the high islands may cause to the aerial current, thus INTRODUCTION. xxxvii creating a greater pressure of the atmosphere. I have before remarked that the climate on the east and west sides of the large islands is dif- ferent; a fact we had an opportunity of proving while engaged in this Group. At the same hours we found the mean difference of the tem- perature to be 2° less on the lee side than it was on the weather side, but the greatest difference was 4'23°. This was doubtless the effect of condensation taking place on the weather side, while evaporation was going on rapidly on the lee side. The standing of the barometer was also found to be '126 in. higher on the wea- ther side. The diagrams on Plate XIII., page 402, exhibit the mean daily variation of the thermometer and barometer, that at Ovolau while we were stationary, and the other while we were moving about from port to port of the northern large island. The variation of the temperature may be attributed to the advance of the season rather than to any change of locality. During our stay, the lowest temperature shown was 68°, and this in mid-winter. Feb- ruary and March are considered the most stormy months, when heavy gales are frequent. Those that have been experienced, begin at the northeast and shift round to the north and northwest, from which latter quarter they blow with most violence, and clear off with the wind from the west and southwest. I endeavoured to trace the gale which happened at these islands on the 22d and 23d February, in some connexion with those which occurred at New Zealand, but without success. Strong winds pre- vailed at Tonga, but they had no gale there. The same gale, how- ever, was experienced off Erromango ; the time of its occurrence being the 28th, 29th, and 1st March; the position was between 500 and 600 miles to the west-by-south of the Feejee Group. The wind was from the southeast to south-southeast; this would lead to the belief that the storm had passed to the northward and westward, travelling to the westward. The mean solar radiation at the Feejee Group was found to be, sun 97°, shade, 72°, difference, 25°; maximum, 110°, minimum 82°. FEEJEE GROUP TO HAWAIIAN ISLANDS. — In this passage we made a course about north-northeast, from 17° south to 21° north latitude, traversing the central part of the Pacific, on a line 2500 miles in extent. On Plate XIII., page 402, the track is shown, and the variations of the instruments. The depression which took place in the barometer, cannot fail to be remarked on inspecting this diagram ; and in order to show that this was not only the case on one passage, I have given 10 XXXviii INTRODUCTION. on the same plate a diagram of the Relief's track, the year before, and refer to the Peacock's track and observations on Plate XXIIL, Ap- pendix, the year after, which were nearly over the same course ; and, the depression of their barometers being reduced to the same standard, they very nearly correspond. The diagrams also point out the changes that took place in the temperature of the air and water, and show that they attain their maximum between 5° and 7° south latitude, in these longitudes. It also will be seen that the thermometer indicates the same temperature in the latitude of 21° north, that it has in 15° south latitude. In passing through the belt of ocean comprised within the 10th degree of latitude on either side of the equator, we found the mean degree of moisture to be -868, and the solar radiation 18°. We lost the southeast trades in 7° south latitude; they afterwards conti- nued variable, lasting but a few hours from any one direction. When in latitude 3° south, we had a heavy fall of rain, 5'2 inches, the tem- perature of which was 02°, air 70° ; the upper stratum of clouds, after it ceased, was seen moving from the east-northeast. The variable winds accompanied us until we reached the latitude of 8° north, when we met the northeast trades. During this passage of 43 days, the maximum temperature was 88°, minimum 73° ; the greatest oscillation of the barometer -280 in. The other vessels of the squadron made the passage at the same time, and all their observations tend to confirm those of the Vincennes. HAWAIIAN ISLANDS — Our observations at these islands continued through a space of six months, from September to April, 1840—41. The first two months of this time they were made on the Island of Oahu, and the last three on Hawaii, the former on the leeward and the latter on the windward side. These will be found projected in the dia- grams, on Plate XIV., page 440. The mean temperature in the first period at Honolulu (Oahu), was 78'01°, varying from 70° to 89°, and during the last at Hilo (Hawaii), 70'09°, and varying from 57° to 82°. The oscillations of the barometer are greater than in south latitude, and more fluctuating, being '540 in. The mean standing of the barometer was 29-973 in. The column generally rises with the northwest winds, and is depressed by the northeast. The tropical hours for 47 days (hourly observations) correspond to 3 h. 36 m. A. M., 9 h. 36 m. A. M., 3 h. 12 m. P.M., 9 h. 30 m. p. M. The mean annual temperature, by the ob- servations kept for several years at Honolulu, is 75'8°, that of a sunken thermometer, six and a half feet deep, gave 82'5°.* The diurnal vari- * I am at a loss to account for this apparent discrepancy between what the buried thermometer gives, and the moan annual temperature for several years ; the thermometer INTRODUCTION. XXxix ation is about 12° Fahrenheit, and its extreme annual range 37°. The solar radiation 21'4°. The climate of these islands varies according to the elevation; in speaking of the climate, I allude to that part on the coast, nearly on the sea level. The moisture depends upon the situation, whether high or low, or on the leeward or windward sides of the island; the leeward side is free from rain, while the windward side has an almost constant succession of showers ; these continue during the preva- lence of the northeast trade winds, which last for nine months of the year, from March till December. In the winter months they are sub- ject to calms, and occasionally to southwest gales; these do not appear to partake of the whirlwind character, but are accompanied by a deluge of rain. The trade winds blow with great strength during a part of the day, but the nights are calm and beautiful. In the summer months heavy dews prevail, but they are not considered unhealthful. The inhabi- tants generally prefer to reside on the leeward side of the islands. The quantity of rain which falls annually is variable; at Honolulu, in 1837, it was 21-1 in., and in 1838, 46-8 inches. During our stay at the island of Hawaii, we ascended to the top of Mauna Loa, 13,4-40 feet above the level of the sea, and 60 miles west of Hilo. In order to give some idea of the position which we occupied, and where the phenomena were observed, the following description of the shape of the island of Hawaii seems necessary. It is of triangular form, with its longest side to the west, and embraces about 3500 square miles ; its whole surface is occupied by three mountains. Mauna Loa is nearly in the centre, and is a huge flattened dome, rising from a base 60 miles in diameter; Mauna Kea, 27 miles to the north, 14,000 feet elevation, and to the west; Mauna Hualalai, at a distance of 24 miles, 10,000 feet high. Between the three mountains lies a vast plain, strewed with lava and ashes, which the mountains have vomited forth. All the surface above an elevation of 6,000 feet, is destitute of wood. The top of Mauna Loa has a crater one mile in diameter, and 760 feet deep : our position was within 80 feet of the edge. The simultaneous observations were continued through a period of 9 days ; they are projected on the diagram, Plate XV., page 490. The oscilla- tions of the barometric column, it will be seen, are nearly coincident, but in the thermometers we find that the range is much greater at the summit than below, and that even the maximum and minimum hours was placed in a bottle of water, which was buried in black scoriae, and remained there fifteen days. xl INTRODUCTION. do not correspond : while the one above passed through a range of 27°, the one below changed but 13°. The observations made with a view of determining the height in feet due to each degree of temperature during our stay at the summit and at the station we occupied on the mountain side, are given in the following table ; these results, it will be seen, vary in consequence of the range of temperature being so much greater at the upper stations than at the lower, which must affect them according to the hour in which the observations are made. If the means are to be taken at the maximum hours, the result will be too great, and if at the mini- mum hours, too little, and it also appears that the localities have their influence. Hours.

The height due to a decrease of one degree in the boiling point of water, at the above places was 537 to 550 feet. Mean solar radiation, sun, 110°, shade 82°, difference 28°.
