By the Right Hon. the Earl of Crawford, K.T., F.R.S. It is usually supposed that when a man takes upon himself to write a Preface or an Introduction to the work of another, he should have some qualification — some knowledge of the subject to be dealt with. It is best, therefore, that I do at once disavow any qualification, and confess to a lamentable ignorance on the subject of Natural History. My only desire is to relate in a few words how it came to pass that the possibility of the writing of the book arose. For many years it has been my lot to live in close communion with two inseparable hangers-on — the one rheumatism, the other asthma. I found relief by going to sea, provided it was towards the Sunny South. The cold and damp of a home winter I have not faced for fifteen years. In 1902 I was preparing to go round the world when one of my brother trustees of the British Museum suggested that I ought to bring back xii VOYAGES OF A NATURALIST something for the Natural History Department. The result was that I was strongly recommended to obtain the assistance of Mr. Michael Nicoll. Such was the beginning of a friendship which has endured the severest known test — that of living together at peace on a ship through long calms. We have had three voyages, in the course of which we have passed many southern seas, calling at various islands, and always adding to the store for the Museum — thus sailing down the east coast of South America through the Straits of Magellan up to Valparaiso in Chili, we struck out west for an eight thousand mile run across the Southern Pacific Ocean, visiting islands new to us all, each more charming than the other, and so home after going round the world. Again, we fitted out for a less ambitious cruise in the West Indies and the Gulf of Mexico. How we again set forth for the wilder and less known Southern Indian Ocean, taking on the way the islands of the South Atlantic — running- through the seas of Vanderdecken, though we did not see the Phantom Ship ; how we encountered two nice little cyclones on the Madagascar coast, and got into the group of practically unknown islands to the North, where man is so seldom seen that the birds take no heed of the visitor ; how we got ashore, and got off again without hurt — all these things are told in the pages that follow. INTRODUCTION xm But what those pages do not tell falls to my lot. It is to say how much I and my fellow trustees of the British Museum have appreciated the work done by Mr. Nicoll, his skill in the preparation of the many hundreds of specimens now in the National collections, and his whole-hearted zeal for his favourite science. Time severs many links and brings to some promotion. Thus, on his return from our last voyage, Mr. Nicoll was appointed by the Egyptian Government to the post of second in charge of the Zoological Gardens at Giza, near Cairo, and thus our rambles together are as of the past ; but I trust that the pleasant hours in many and various scenes of the world may be brought to life again in this book, which I hope will run to many editions. My "rolling stone" has started. "Valhalla" is now taking in her stores, and ere these words of mine see the ink of the press, I shall be well on my way to the far East — alas, without my companion. CRAWFORD. PREFACE. Lord Crawford has explained in his most kind Introduction to this little book how it came to pass that I accompanied him on three delightful cruises in his yacht " Valhalla." To visit so many out-of-the-way spots, and to see so much of the world under these charming circumstances, was an ideal experience and a generous education. Seldom does it fall to the lot of a naturalist to be given the opportunity of examining the fauna of so many rarely- visited places, nor can such experiences fail to produce matter for life-long reflection. No words of mine can express adequately the gratitude I feel to my ever-kind and generous host for having provided the means to enjoy these rare and never-to-be- forgotten experiences ; I can but say that whatever success may have been achieved in making collections during these voyages is due to Lord Crawford's ever-ready help and encouragement. I should like also to offer my very best thanks to Dr. P. L. Sclater, F.R.S., to whom I am in- debted for my introduction to Lord Crawford. xvi VOYAGES OF A NATURALIST I am but one of many young ornithologists who have been started and encouraged in their career by Dr. Sclater. In the following pages I have devoted a chapter to each of the most interesting and the least-known islands or regions explored. Some places were visited more than once, and in such cases all my observations have been brought together, so that the course of each voyage has not been always strictly adhered to. It will, therefore, be well to give a brief itinerary of each voyage, and to set down the chief results obtained. First, however, I must tell of the good ship that carried us safely through calms and storms by sail and steam for over 72,000 miles. " Valhalla," R.Y.S., is, I believe, the only ship- rigged yacht in the world. She is of 1700 tons displacement, and is fitted with auxiliary screw, which, under favourable conditions, will drive her through the water at a speed of about 10 \ to 11 knots an hour. It is under sail, however, that " Valhalla " is at her best, and on many occasions we logged 16 knots per hour. A better " sea " ship has probably never been built, and under the worst conditions it was rarely that she took any water aboard. The way in which she rode out a cyclone off the Mozambique coast was wonderful ; the waves towered to a height beyond belief, yet not a drop of water came aboard, nor was any damage sustained. In fact, the only serious > fc H O H _: O o CO < Z Q CO P 5 > e o o pi ** PEEFACE xvn mishap experienced during my voyages occurred off Cape Guardafui, in 1903, when a sudden whirl- wind snapped the jibboom, hurling it into the air like a straw. " Valhalla " was the first ship to be fitted with the " Brougham patent electrical steering-gear," an invention which makes steering possible from any part of the ship. In 1905 she took part in the famous yacht race for the German Emperor's Cup, from Sandy Hook to the Lizard, and, although by far the largest yacht, she came in an easy third. The accommodation on board is palatial — most ample " headroom," large cabins, and electric light throughout. The freezing room is capable of carrying many tons of meat, sufficient for a very long cruise. The total number of crew carried, including officers, engineers, and stewards, was about sixty-five. Indeed, under any consideration, a better or more beautiful yacht could not be imagined. First Voyage. During the first voyage our party consisted of Lord Crawford, Major L. B. Wilbraham, Dr. W. B. Macdonald, and myself. We left Cowes on 19th November, 1902, on a voyage which lasted rather more than eight months, and during this time 38,000 miles were covered. After calling for coal at Lisbon, Madeira, the B xviii VOYAGES OF A NATURALIST Canaries, and Cape Verde Islands, we ran down the Atlantic coast of South America, calling at some of the islands, and visiting Bahia and Monte- video for coal, thence through the Straits of Magellan and Smythe's Channel into the South Pacific. From Valparaiso we sailed westwards amongst the South Sea Islands ; thence through Torres Straits into the Indian Ocean. After leaving Ceylon we steamed south-westwards until the African coast was sighted, hoping — and in this we were partly successful — to escape the fury of the monsoon. The remainder of the voyage home was performed by way of the Red Sea and Mediterranean, and, after a pleasant passage through these waters, Cowes was reached on 1st August, 1903. Below is given a detailed itinerary of this voyage : — Lisbon, 24th to 26th November, 1902 ; Madeira, 29th to 30th November ; Las Palmas, 1st to 3rd December ; St. Vincent, Cape Verde Islands, 10th to 12th December ; St. Paul's Rocks, Mid-Atlantic, 17th to 18th December ; Fernando de Noronha, 20th to 22nd December; Bahia, Brazil, 26th December to 5th January, 1903 ; Montevideo, 14th January to 20th January ; Straits of Magellan, 28th January to 5th February ; Smythe's Channel, 5th to 10th February ; PREFACE xix Valparaiso, 14th to 24th February ; Easter Island, 10th to 13th March ; Pitcairn Island, 22nd to 23rd March ; Tahiti, Society Islands, 31st March to 17th April ; Tutuila Island, Samoan Group, 22nd to 24th April ; Apia, Upolu Island, Samoa, 25th to 29th April ; Suva, Fiji Islands, 3rd to 6th May ; Thursday Island, Torres Straits, 18th to 23rd May ; Singapore, 3rd to 9th June ; Colombo, 17th to 20th June ; Aden, 2nd to 3rd July ; Suez, 10th July ; Port Said, 11th to 13th July; Gibraltar, 22nd to 26th July ; Cowes, 1st August. The collections made during this voyage com- prised some two hundred and twenty bird-skins, thirty mammals, a few hundred fishes and reptiles, and several hundred butterflies, moths, and other insects. No new species of bird or mammal was obtained, but a series of skins of the Pitcairn warbler (Tatar e vaughani) was of considerable interest. The types of this species are spirit specimens in the British Museum : no skins of the bird had ever been collected before ; moreover, the fact that the first plumage of the young differs very considerably from that of the adult of this warbler was unknown until we obtained specimens. b2 xx VOYAGES OF A NATURALIST Another interesting discovery we made was that Richardson's skua (Stercorarius crepidatus) winters in great numbers in the Bay of Valparaiso — many hundred miles further south on the west coast of America than it has previously been found. The two peculiar species of land-birds which inhabit Fernando de Noronha, the Brazilian convict island, are also perhaps worthy of notice, on account of their rarity in collections. These are a flycatcher (Elainea ridleyana), and a warbler (Vireo gracilirostris), which were pre- viously represented in the British Museum by the type-specimens only. Amongst the fishes obtained during this voyage one — Corvina crawfordi — from the harbour of Montevideo, proved to be new to science. A species of microlepidoptera — Pyroderces crawfordi Walsingham — from Tahiti, was also previously unknown, and another specimen of this group of little moths — Heliostobes mathewi — from Valparaiso, forms the only other known specimen in addition to the type. Second Voyage. The second voyage upon which we started from Cowes on 18th December, 1903, was to the West Indies. Our party for this cruise consisted of Lord Crawford, Mr. C. R. Pawson, Dr. R. C. MacWalters, and myself, though at Barbadoes PREFACE xxi we were joined by Colonel C. E. Swaine, who visited all the West Indian Islands with us, but left us at Florida for a trip through the United States. The voyage occupied about five months, and after calling at the Canaries for coal we steamed across to Barbadoes, thence to St. Lucia, St. Vincent, and Grenada, afterwards running up the entire chain of islands to Jamaica, the Caymans, and then on to Cuba. Thence we proceeded to Florida, where some excellent tarpon fishing was enjoyed, and after a flying visit to Key West, for the purpose of coaling, we returned home via Bermuda and the Azores, reaching Cowes on 8th May, 1904. An itinerary of this voyage is appended : — Madeira, 24th to 27th December, 1903 ; Teneriffe, Canary Islands, 28th December to 1st January, 1904 ; Barbadoes, West Indies, 15th to 21st January ; St. Lucia, 22nd to 25th January ; St. Vincent, 25th to 27th January ; Cariacou, 27th to 28th January ; Grenada, 28th January to 1st February ; St. Lucia (second visit), 2nd to 5th February ; Martinique, 5th to 7th February ; Dominica, 7th to 10th February ; Montserrat, 10th to 12th February ; St. Kitts, 12th to 15th February ; Antigua, 15th to 17th February ; St. Kitts (second visit), 17th to 18th February; St. Croix, 19th to 21st February ; xxii VOYAGES OF A NATURALIST St. Thomas, 21st to 24th February ; Porto Rico, 24th to 26th February ; Jamaica, 29th February to 8th March ; Grand Cayman, 9th to 13th March ; Little Cayman, 13th to 14th March ; Havana, Cuba, 17th to 21st March ; Punta Gorda,Florida,22nd March to 4th April ; Key West, Florida, 5th to 8th April ; Bermuda, 13th to 20th April ; St. Michael's, Azores, 29th April to 2nd May ; Cowes, 8th May. The number of birds obtained during this trip to the West Indies somewhat exceeded four hundred, of which the following three proved to be new to science : — Dendroeca crawfordi, from Little Cayman ; Vireo laurae, from Grenada ; Pitangus caymanensis, from Grand Cayman. The birds found in all the West Indian Islands are of great interest, as no two islands have an avifauna exactly similar, so that all our collections were of value. The Cayman Islands specimens are worthy of particular notice, as nearly all the resident birds are peculiar to the islands, and there were previously very few specimens from this locality in the British Museum. About one hundred fishes and reptiles were also obtained, but not one was new, nor were there any of great rarity. The most interesting, perhaps, were the five fine specimens of tarpon, which we caught off the Florida coast. These ranged in size from 40 to 95 pounds in weight, X x i— i X X < o S-i x a P O M ^S x X I— I PQ P5 o < x 02 PREFACE xxni and I preserved the skins of four of them on our homeward voyage. About two hundred butterflies, moths, and other insects were also obtained. The most interesting islands visited during our sojourn in the West Indies were Martinique, famous for its volcanic eruptions in 1902, and the Cayman Islands, which have been but seldom visited by a naturalist. Third Voyage. It was not until the autumn of 1905 that I again set out in the " Valhalla " on my last and, perhaps, most interesting voyage. On this cruise we had a somewhat larger party, for besides Lord Crawford, the Hon. Walter Lindsay, Dr. A. Dean, and myself, Mr. E. G. B. Meade- Waldo was invited to accompany us for the purpose of collecting insects, and thus I was able to devote my whole time to birds, mammals, fishes, and reptiles, with the consequence that examples of several new species were obtained. We sailed from Cowes on 8th November, 1905, and, after calling at Las Palmas, ran down amongst the South Atlantic Islands to the Cape of Good Hope ; thence northwards through the in- hospitable waters of the Mozambique Channel to Madagascar and the little-known islands which lie to the north-west. After visiting the Seychelles we returned home via the Suez Canal, xxiv VOYAGES OF A NATURALIST completing a voyage of seven months, during which time we had covered about 19,000 miles. The following is the detailed itinerary : — Las Palmas, 13th to 16th November, 1905 ; Put back to Las Palmas owing to illness of one of the crew — 17th November; St. Paul's Rocks, 2nd December ; Bahia, 10th to 30th December ; South Trinidad, 3rd to 5th January, 1906 ; Martin Vas, 5th January ; Tristan da Cunha, 17th to 20th January ; Cape Town, 28th January to 8th February ; Durban, 14th to 15th February ; Mayotte, Comoro Islands, 23rd February to 3rd March ; Diego Suarez, Madagascar, 4th to 9th March ; Glorioso Island, 10th to 11th March; Assumption Island, 12th to 13th March ; Aldabra, 13th to 16th March ; Aground on Assumption, 16th to 17th March ; Mahe, Seychelles Islands, 22nd March to 2nd April ; Praslin and Felicite Islands, Seychelles, 2nd to 5th April ; Mahe (second visit), 5th to 8th April ; Aden, 14th to 17th April ; Suez, 23rd April ; Port Said, 24th to 27th April ; Gibraltar, 5th to 8th May ; Cowes, 13th May, 1906. The results obtained during this voyage were more important than those of the two preceding ones. The collection of bird-skins, numbering five PREFACE xxv hundred, contained specimens of eight species new to science. Besides these there were many rarities, few of the birds of the small coral islands to the north-west of Madagascar having been previously represented in the National collection. The new species discovered were as follows : — A white tern (Gygis crawfordi) from South Trinidad ; A diving petrel (Pelecanoides dacunhae) from Tristan da Cunha ; A paradise-flycatcher {Terpsiphone lindsayi) from Mayotte, Comoro Islands ; A swift (Cypselus mayottensis) from Mayotte, Comoro Islands ; A ground-cuckoo (Centropus assiimptionis) from Assumption Island ; A turtle-dove (Turtur assumptionis) from Assumption Island ; A heron (Butorides crawfordi) from Assump- tion Island ; A sunbird (Ginnyris mahei) from Seychelle Islands. Many fishes and reptiles were collected, but none of these proved to be new or of great interest, except a large specimen of the ribbon-fish (Regalecus), which was obtained at Cape Town. This fish is rare in collections, its pelagic habits making its capture difficult. Of the insects obtained I learn that several belong to new species, or are otherwise rare or xxvi VOYAGES OF A NATURALIST important, but at present I believe nothing has been published concerning them. The most interesting islands visited were un- doubtedly South Trinidad, Dassen Island, Glorioso, Assumption, Aldabra, the Comoros, and Seychelles, all of which have been fully dealt with in their proper place in the following pages. This, then, is a brief outline of my three voyages on the " Valhalla," and if some of the notes in the following chapters are not as full as is desirable I must remind my readers that our stay in many of the " ports of call " was of very short duration — a difficulty only to be expected on a long voyage, when coaling or other necessary though wearisome proceedings effect frequent delays in the larger ports. If, however, my account of our experiences should at some future time prove of use to any of my readers who themselves set off for these distant parts of the world in search of natural history treasures, or if the following pages give to the reader even a fraction of the pleasure which I myself experienced in visiting the islands therein portrayed, I shall feel that the book has not been written wholly in vain.

CHAPTER I. saint paul's rocks. Saint Paul's Rocks, situated in mid- Atlantic, about 540 miles from the nearest point of the coast of South America, and 15 miles north of the equator, are probably the most interesting rock-islets in the world. Roughly about half a mile in circumference, this group is composed of five peaks of rock, the highest of which is only 64 ft. above the level of the sea. Darwin has stated* that Saint Paul's group is not volcanic, and thus forms the only island in the world, with the exception of the Seychelles, that is of neither volcanic nor coral formation. These rocks are surrounded by deep sea, and the Challenger Expedition could discover no ridge under the sea to connect them either with the mainland or with the islands of Fernando de Noronha, about 200 miles to the south. Owing to their small size, Saint Paul's Rocks cannot be seen, even in clear weather, from a * "Voyage of the 'Beagle.'" 2 VOYAGES OF A NATURALIST greater distance than eight miles. Their appear- ance from a short distance is most peculiar, the two highest peaks being white with the droppings of the numerous sea-birds which nest on them, while the remainder are of a deep greenish-black, very dark in contrast to the white peaks. The outlying rocks, as can be seen during the fall of the swell, are much worn below the water-line. My first visit to these interesting rocks was made in 1902, during my first voyage with Lord Crawford in the " Valhalla." They were sighted from aloft at 1.30 p.m. on the 17th December, and shortly afterwards became visible from the deck. Numbers of gannets appeared and circled round the yacht, while, as we gradually drew near, great numbers of birds were to be seen flying in all directions round the highest peaks. At 3.30 we were close in, and shortly afterwards a boat was lowered and we set out for the shore. The weather was perfectly fine, but, owing to a slight swell, the surf was breaking on the rocks in a most forbidding manner. As we rowed closer, however, we found that, by waiting and choosing the right moment, the boat could be backed in to a projecting portion of the rock, and then, as we rose on the swell, it was not difficult to jump ashore. Accordingly we backed in carefully, and took our turn to wait for the lift of the swell and then BOOBIES 3 jump. At one moment the rock towered above us, at the next the boat flew upwards until it was level with the landing place — then was the time to jump, and as one jumped the boat was pulled out clear of the surf. Thus one by one we landed safely. As soon as we were ashore we noticed a vast number of crabs* crawling about in all directions. Some of these crabs were of a green colour ; these were the smaller and more numerous, perhaps the younger ones, while others, which were larger, were of a bright vermilion. The landing place we had chosen was at the foot of the highest peak, which Moseley calls Booby Hill,t and certainly this name is well chosen, for the peak was covered with boobies, a species of gannet — Sulci leucogaster — and their nests were so close together that it was almost impossible to walk without stepping on either eggs or young. The young boobies, sometimes two in a nest, were of all ages, from bare, newly-hatched chicks to fully-fledged young. The nest of this gannet is merely a collection of old and dirty feathers and loose stones. Round about each nest were quantities of flying fishes in all stages of decay, brought there and disgorged by the parent birds as food for the young. The freshest part of this food supply, we soon discovered, * Grapsaa strigosus. f " Notes of a Naturalist on H.M.S. 'Challenger.'" 4 VOYAGES OF A NATURALIST made excellent bait for the innumerable fishes which swarmed round the rocks ; but as we found later, by accident, the best and freshest bait was to be procured by gently prodding an old gannet while it was sitting on its nest, when it would at once disgorge a fish. It was by no means pleasant to walk about amongst these nesting birds, and, indeed, we found it to be a most painful proceeding, as both old and young pecked viciously at our legs. The young birds were especially annoying, and would get out of their nests and follow us, snapping savagely at our legs with their long sharp bills. At the base of Booby Hill I came on a colony of noddy terns.* This bird lays its single egg on the bare rock. Most of the eggs were hard set, and there were many young ones of various ages. Although very tame, the noddies were not so bold as the boobies, and we did not succeed in catching more than one adult bird of this species with our hands. Running about among the noddies we saw a turnstone,f a well-known visitor in the spring and autumn to the shores of the British Isles. In the winter it is distributed practically over the whole world. This bird has not hitherto been recorded from Saint Paul's Rocks, however, and it was probably resting there while on migration. Besides the birds already mentioned, a second * Anous 8tolidus. f Strepsilas interpres. K5 I H u , ► t 1 CO M o o p; CO CO \ \ li4 m m NESTING AT ALL SEASONS 5 species of noddy tern — Micranous leucocapillus — a smaller and darker bird than the common noddy, was seen and obtained. This small tern was not nearly so abundant as the larger species, and it was not found nesting on Booby Hill. It was also far more shy, and specimens were only obtained with difficulty. Thus there are only three species of birds which nest on Saint Paul's Rocks, and they appear to breed all the year round. The naturalists of the " Beagle " landed there in February, those of the " Challenger " in August, while we were there in December, and on all of these occasions both eggs and young were found. One of the sailors landed with us in the boat to collect eggs for eating purposes. Whether any of the crew ate any I never heard, but as nearly all those we obtained were hard set, I should imagine they did not. I have a vivid recollection, too, of being called up in the small hours of the following morning, with the news that several of the eggs had hatched during the night. From the top of the highest peak one could get a good view of the rocks. They are divided up into groups of jagged peaks, each group being separated from its neighbour by a channel through which the sea rushes with great violence. The rock on which we landed appeared to be the largest, both in height and circumference. At the foot of Booby Hill were several tidal c 6 VOYAGES OF A NATURALIST pools in which many species of small fishes were seen, but all attempts to catch them with a net proved futile. A great many fish were, however, caught in the sea by fishing from the rocks. Of these a species of "cavalli" weighed in some cases as many as twelve pounds. Fishing here pre- sented a somewhat unusual difficulty, for sharks swarmed in incredible numbers, and it was a difficult task to avoid hooking them instead of more serviceable game ; indeed, so numerous were the sharks that, on our return to the ship, we found that during our absence no less than twenty had been caught, all of them at no greater distance than two hundred yards from the shore. As to the other inhabitants of the rocks, Darwin mentions the following : A pupiparous fly (living as a parasite on the booby), a beetle (Quedius), a, tick, a small brown moth belonging to a genus which feeds on feathers, and a woodlouse. Moseley says : " We found two species of spiders .... and, in addition to the insects noted by Darwin, the larva of a moth, apparently a Tortrix, and a small dipter .... but could not find either the beetle or woodlouse." We searched carefully and obtained specimens of the feather-feeding moth, a tiny beetle, and a small cricket, but failed to find either the wood- louse or the spider. The pupiparous fly was, however, noticed on the booby. The heat on Saint Paul's Rocks was intense, SHARKS 7 the sun, beating down on the bare rock, made the place like an oven, and the only shade was that thrown from Booby Hill towards evening. Shortly before sunset we went on board, fully determined to land the next morning on another part of the rocks. Getting off was, we found, a much more difficult business than landing, but at last it was safely accomplished. Several fishes and one bird were dropped into the water during the process of embarkation, and they were im- mediately taken by sharks, so it was just as well that none of our party slipped into the water. Perhaps a shark is not so dangerous to human beings as it is usually supposed to be. That there are some sharks which will attack a man in the water is, of course, certain, but I think that there are not very many that will do so. During two visits made to Saint Paul's Rocks we tried to ascertain the nature of the food of these sharks. We cut open and examined at least thirty of them, but in only one did we find the remains of food — a half-digested fish. Of what, then, does their food consist ? It seems incredible that they can feed entirely on fishes, as anyone will realise who has seen the slow, almost lazy, way in which they take their prey. Judo-ino; from the enormous number of sharks round Saint Paul's Rocks, there should be a great supply of food. Of course it is possible that they can exist for a length of time without food. That c 2 8 VOYAGES OF A NATURALIST they go elsewhere for their food is not likely, as these rocks are far away from any other land. During our second visit a shark, which had been shot with a rifle, sank, and as all its companions, of which there were a great number round the ship at the time, followed it down, and on reappearing refused to look at our baits, I imagine that they devoured it. During the night of 17th December we steamed slowly away from the rocks, but at daylight we returned, and, lowering a boat, again landed. This time we went ashore on one of the rocks at the further end of the bay, which is formed by the semi-circular nature of the group. The weather being even finer and the sea smoother than on the previous day, we landed without difficulty, and at once climbed to the highest peak of this rock, which is 60 feet in altitude, and the second highest of the group. Here I was delighted to find the nests of the smaller noddy tern, which I have mentioned as having been seen on the previous day. This bird lays its egg in a most curiously constructed nest. A mass of fine seaweed is cemented to a small jutting ledge of rock, the cement being formed of the droppings of the birds. We found altogether four of these nests, each of which con- tained a single egg. A few of the larger noddies were also breeding here, but these, as on Booby Hill, had laid their eggs on the bare rock, without ss 00 _ O x Ph Eh' fa o Eh X o K H a EH o 00 A SECOND VISIT 9 making any attempt at a nest. Moseley, in describ- ing these bracket-like nests, suggests that it is only the strongest birds that take possession of the favourable points of the rock on which they are placed, although he adds a footnote to the effect that at the time of his visit he did not realize that two species of noddies inhabit Saint Paul's Rocks. It is, however, quite obvious that it is not the strongest birds, but only the smaller noddies, which occupy these ledges, since the larger noddy was in no instance found nesting upon them. This day, while we were on the rocks, a ship passed by, close in. It is only occasionally that ships sight these rocks, and then only to determine their exact position. No one, it is almost certain, had landed on Saint Paul's Rocks since the visit of the " Challenger " until we were there just twenty-nine years later. At 4.30 p.m. on the 18th December we sailed away, bound for Fernando de Noronha, and as I stood on deck and watched these interesting little islands fading away in the distance, I little thought that in three years' time it would be my fortune to see them again. It was on my third voyage in 1905, while on the way to Brazil, that Lord Crawford suggested that we should renew our acquaintance with these little-known islands. Shaping our course ac- cordingly, we sighted the rocks on 2nd December, 10 VOYAGES OF A NATURALIST and, after a few minutes' steaming, drew up close to our former landing place. The weather was, unfortunately, by no means so kind on this occasion as on our former visit. A strong wind was blowing, and the surf was break- ing with great fury on the foot of Booby Hill. It might have been possible to land, but we de- cided that, under the conditions prevailing, it was too risky to venture close to the rocks, therefore we were forced to content ourselves with a distant view of the boobies. Some time was, however, spent over shark fishing, and we had hopes that the weather might improve. A number of sharks were caught, and in this way we spent the greater part of a day. As the sea was still high at sunset, Lord Crawford decided that it was not worth while to remain longer, so we sailed for Bahia, Brazil. During this visit to Saint Paul's Rocks we noticed that the birds were present in about the same numbers as before. Boobies of all ages were flying round the ship the whole time we were there, and many noddies were also seen. CHAPTER II. FERNANDO DE NORONHA. On 20th December, 1902, the island of Fernando de Noronha was sighted, and at 4 p.m. we dropped anchor off the settlement. On the island is a Brazilian convict settlement, and permission to land is by no means easy to obtain. The " Challenger " Expedition was not allowed to make collections there, and Mr. Ridley, who visited the island in 1887, was, previously to our visit, the only naturalist who had collected with any thoroughness. Of the three species of land-birds which he obtained, two proved to be new to science. It was therefore a matter of great satisfaction that, by the courtesy of the Governor of the island, we were allowed to land and make natural history collections, and not only that, but were also generously provided with guides and horses. The most remarkable physical feature of Fernando de Noronha is a gigantic column of rock standing erect on the highest peak. This 12 VOYAGES OF A NATURALIST column appears to be a smooth mass of rock, and looks as if a slight push would send it head- long into the sea. Another marked feature, which is visible at a considerable distance, is an opening through the sea-cliff at the south-western extremity of the island. This boring has been made by the sea, and is known as the " hole in the wall." Just opposite our anchorage, and close to the settlement, there was also a magnificent " blowhole " in the cliff, through which the air was driven, by the rise and fall of the sea, with a loud roar every few seconds. The island slopes gradually upwards from the sea, and its general appearance from a little distance is green and fertile. When we landed we found that the cause of this apparent fertility was a thick growth of fig trees, which covered most of the island. Maize is, however, grown at certain seasons of the year, and in a letter received by Doctor Macdonald some months after our visit, one of the Englishmen living on the island describes it as looking very green and fresh, owing to the abundance of the maize crop. As soon as a boat had been lowered we started for the shore. The surf was breaking with such fury on both the charted landing places that we were forced to abandon the idea of getting in at these spots ; but we found that, by backing the boat to a jutting mass of rock, we could, with a little difficulty, scramble ashore. A CONVICT SETTLEMENT 13 The Governor, accompanied by two English- men who manage the telegraph and Lloyd's signal station, had come down to meet us, and, thus accompanied, we proceeded to the settle- ment, where arrangements were made for a collect- ing expedition on the following day. While we were at the Governor's house a bugle was sounded to summon the convicts. There were about 200 of them, all under long sentences, most of them having been convicted of murder. One man, who was told off as a guide to our party, was said to have committed seven murders, and as he owned to five of them, I have no doubt that we were correctly informed. After their names had been called, the convicts dispersed for the night, about fifty being locked up in the gaol, and the rest going off to their own houses. Most of these men have wives and families, and, as far as we could judge, their lives were not hard. They have to work three hours a day for the State, but the rest of the day they can spend as they like, though all have to appear when the bugle is sounded in front of the Governor's House. Shortly after the convicts had dispersed we started for the landing place. At its best this is a difficult place from which to embark without getting wet, and it was seldom that we landed there or got away without getting soaked by the waves. 14 VOYAGES OF A NATURALIST The next morning we landed early, and, walking to the settlement, were met by our English friends, who had procured ponies for us on which to cross the island. During our ride I saw a pair of white terns (Gygis sp.), the most beautiful of all the tropical sea-birds. Later on we saw many of these terns in the various islands we visited, and, whether hovering over the deep blue sea of the South Pacific, or sailing round the palms of a coral island in the Indian Ocean, they seem equally at home ; wherever they were seen the snow-white of their plumage and the deep dark blue of their eyes made them ever memorable. At the base of the column on the peak we made our first acquaintance with frigate birds,* which were sitting in numbers on some bushes ; their scarlet pouches were extended, and looked in the distance like large red blossoms. It is only in the breeding season that frigate birds develop this curious ornament. When closely examined it is seen that the pouch is formed by a bare patch of skin on the throat, which can be expanded by the bird at will. At times a great bladder as large as a football is thus formed. When the bird is taken in the hand and carefully examined, the whole of the body appears to be inflated. On skinning the bird it is at once seen that the whole body is enveloped with a mass of air cells. The pouch is only an exaggerated form of such an air * Fregata aquila. THE FRIGATE BIRD'S POUCH 15 cell, and, being larger than those on the rest of the body, is more noticeable. In the breeding season the pouch is constantly being inflated, and, as a consequence, the skin of the throat becomes stretched to such a degree that when not inflated it hangs down in a loose fold below the bill of the bird. It is only the males that are able to inflate these pouches in this way, the female having a non-inflatable patch of bare skin of a duller colour on the throat. We afterwards found that by inserting a bicycle pump into the larynx of a freshly-killed male frigate bird and pumping air into the throat, the whole of the body, as well as the throat, becomes inflated. Along the shore we saw a species of the tropic, or bo' sun, bird. This proved to be Phaethon Upturns, and two fine specimens were obtained by Lord Crawford. Several of them were flying along the face of the cliff. The name " bo-sun " is said to have been given to this bird on account of its cry, which is supposed to resemble the pipe of a boatswain's whistle. It must be confessed, however, that the only cry we heard it utter was a harsh scream not unlike that of a tern. A dove known as Zenaida auriculata, which was originally, without doubt, introduced from the mainland of South America, was extraordinarily abundant on this island. They were very tame 16 VOYAGES OF A NATURALIST and fearless, but were not nesting at the time of our visit. Their note is a loud rattling " coo." Insects were not very numerous — bees, dragon- flies, beetles and crickets being the most notice- able, while a little blue butterfly was frequently seen fluttering along at our feet in the pathways through the groves of fig trees. In the houses we collected a number of mosquitoes, apparently of one species only. It seems that it is only in the houses that mosquitoes are troublesome, as, during the whole of the time we were on the island, we were not attacked by these pests out-of-doors, and it was only when we entered a house that they became a nuisance. We went to the furthest extremity of the island in a north-west direction from the settlement. Here we found that the low fig trees, which seem to be the principal trees of the island, were growing in greater abundance than near the settlement. In these trees numbers of small birds, which in general appearance much resembled reed- warblers, were flitting in and out among the leaves in search of insects. These birds proved to be all of the species called Vireo gracilirostris. Their loud, but by no means unpleasant, song somewhat resembled that of a pied wagtail, so familiar as a British bird. This part of the island was steep and precipitous. We followed a path which took us down to the seashore about one hundred feet below, and here FRIGATE BIRDS ON GLORIOSO ISLAM). (See also ( lhapter X.) 11 0.1 BRILLIANT FISHES 17 we noticed numbers of sooty terns,* which were flying in a perpetual stream along the coast, just above the breaking waves. These birds were not nesting at the time of our visit, but we were told that they bred in great numbers on one of the smaller islets, which lies about half a mile off the settlement. A few tropic-birds, which were flying high overhead, appeared from their manner to have nests, which were probably situated in the most inaccessible parts of the cliff. The tide was low, and we were able to walk some distance along the shore, A long ledge of rock was pointed out to us by one of our friends as an excellent place for fishing, and in many shallow pools we saw numbers of» brilliantly coloured fishes ; some of these were blue on the back and yellow beneath. We made repeated attempts to capture them, but to no purpose. It is impossible to make a collection of the whole fauna of an island during a visit of two or three days, as we soon realized ; consequently I spent most of my time searching for the three species of land-birds which inhabit Fernando de Noronha. Specimens of the dove and the warbler, which have already been mentioned, were collected during the morning. As soon as we returned from our excursion across the island a visit was paid to the Governor's garden, where, owing perhaps to the greater abundance of trees, birds were more * Sterna fuliginosa. 18 VOYAGES OF A NATURALIST numerous, and the third species of land-bird, a flycatcher,"' was met with. In this garden, which was nicely laid out and enclosed by an iron fence, were many large cocoanut trees bearing a quantity of fruit. There were also some sapodillas, the fruit of which was ripe at this time. It is greatly appreciated by the people on Fernando de Noronha, and we were persuaded to taste it. Externally it somewhat resembles a small round potato ; the flavour, how- ever, is too much like that of the mango, the suggestion of turpentine which pervades the latter fruit being distinctly noticeable in the sapodilla. Doves were swarming in the garden, every tree and bush being apparently tenanted by them, and the Governor showed us a cage full which had recently been caught. They were, he told us, excellent to eat. There are no indigenous mammals on Fernando de Noronha, but ratsf and micej have been im- ported or have escaped from ships. I did not get any rats, but two mice which we shot were of a pale fawn colour, and probably differed in colour, at all events, from those of their ancestors which first appeared on this island. One of the outlying islets is called " Rat Island," but we were informed that rats were no more numerous there than on the main island. Close to the place where we embarked, we * Elainea ridleyana. f Mus rattus. ± Mus musculus. CATAMARANS 19 noticed a thick-stemmed plant covered all over with small spikes, and bearing leaves like those of the geranium. We were warned by our friends that this plant, when touched, gave a most painful sting. Moseley mentions that, although he used the greatest care when securing a specimen, he got a sting, the results of which he felt for several days afterwards. We afterwards saw this same plant in Brazil. During the second day of our stay on Fernando de Noronha a steamer, which visits the island once every month, arrived, bearing mails for the inhabitants. The advent of the steamer is much looked forward to, as life on Fernando de Noronha for a European is dull in the extreme. As soon as the boat arrived a large raft was pushed off from the shore and anchored outside of the surf. The raft resembled in shape a large table, the legs of which were fixed to a platform composed of a number of logs lashed together. A boat was sent off from the steamer loaded with packages of stores, clothing, letters, and other things, and these were put on to the raft, from which they were landed in native catamarans. The catamarans, which are built on the same principle as the large raft, are of sufficient size to carry one person with comfort besides the native oarsman. They are especially adapted for landing through surf, and they ride over the breaking waves with wonderful buoyancy. 20 VOYAGES OF A NATURALIST We once landed in a catamaran, and all of us got ashore with no more than wet feet. In Brazil we frequently landed through surf in the same way, though the catamarans there are larger and are propelled by two natives. Our time ashore on this second day was limited, and we did not get very far beyond the settlement. Major Wilbraham and I walked for some distance along the shore, and saw the same species of birds as at Saint Paul's Rocks, but we noticed that the turnstone appeared to be quite numerous. There are, I believe, two species of lizards on the island, but we only saw one of them. This was Mabuia punctata, and it seemed to be a most abundant species on every part of the island. As we had many other interesting places to see, our stay on Fernando de Noronha was of necessity very short, and after two days we set sail for Bahia, in Brazil. It is probable that in a few years' time Fernando de Noronha will cease to exist as a convict settlement. We were informed that as capital punishment had taken the place of exportation for life in Brazil, no more convicts were to be sent there. tl < — < < < — CHAPTER III. ITAPARICA, BAHIA. During the three cruises of the " Valhalla," we made two visits to Bahia. On the first occasion we landed on 26th December, 1902, Christmas Day having been spent in sight of the coast of Brazil, while on the second we dropped anchor in the Bay of All Saints on 10th December, 1905. Some six miles from the town lies Itaparica, a large island inhabited by about 30,000 people, and it was here that most of our time (a fortnight on each occasion) was spent. During our first visit some time was occupied in finding the most suitable places for landing on this island, and also in searching for the best spots for collecting birds, butterflies, and other specimens. What we learnt on this occasion, however, proved of the greatest assistance during our second visit, as we were then able to find the passage through the reef with little difficulty, and go at once to our old collecting grounds. Before describing our doings at Bahia, I must refer in detail to an important incident which 22 VOYAGES OF A NATURALIST occurred on the high seas during our second voyage thither. On the 7th December, 1905, when in latitude 7° 14' S., longitude 34° 25' W., and about fourteen miles from the coast of Brazil near Para, a creature of most extraordinary form and proportions was sighted by two of us. At the time we were under sail only, and were slowly making our way to Bahia. It was at about 10 o'clock in the morning, and I was leaning on the rail of the poop deck, when a large fin suddenly appeared close to the ship at a distance of about fifty yards. This fin resembled that of no fish I had previously seen, and I pointed it out immediately to Mr. E. G. B. Meade- Waldo, who was on deck with me at the time, and we watched it together for several minutes. As we passed slowly by, a long eel-like neck surmounted by a head, shaped somewhat like that of a turtle, rose out of the water in front of the fin. This creature remained in sight for a few minutes, but we soon drew ahead of it, and it became lost to view, owing to the ripple of the water. Owing to the fact that we were under sail at the time, it was not possible to go about and make a closer inspection, and with great regret we had to be content with the view we had had of this remarkable monster. A full account of it was given at a meeting of the Zoological Society of London, on 19th June, 1906, and I quote below from the report which was N < m fa o Fh o D H H H fa fa O « o K H P n w i H 05 i 3 fa o W o « CO H w o H CQ P I--A J? •< •3 ?=J O o Q o * w i -S$ H •fci 0 "fc w CO o o J-l 24 VOYAGES OF A NATURALIST printed in the " Proceedings " of that Society (10th October, 1906, p. 721) :— "At 10.15 a.m., on Thursday, 7th December, 1905, when in lat. 7° 14' S., long. 34° 25' W., in a depth of from 322 to 1,340 fathoms, Meade- Waldo and I saw a most extraordinary creature about 100 yards from the ship, and moving in the same direction, but very much slower than we were going. At first all that we could see was a dorsal fin, about four feet long, sticking up about two feet from the water ; this fin was of a brownish-black colour, and much resembled a gigantic piece of ribbon-seaweed. Below the water we could in- distinctly see a very large brownish-black patch, but could not make out the shape of the creature. Every now and then the fin entirely disappeared below the water. Suddenly an eel-like neck, about six feet long and of the thickness of a man's thigh, having a head shaped like that of a turtle, appeared in front of the fin. This head and neck, which were of the same colour above as the fin, but of a silvery-white below, lashed up the water with a curious wriggling movement. After this it was so far astern of us that we could make out nothing else. " During the next fourteen hours we went about twice, and at about 2 a.m. the following day (8th December), in lat. 7° 19' S., long. 34° 04' W., the first and third mates, Mr. Simmonds and Mr. Harley, who were on the bridge at the time, saw THE GREAT SEA-SERPENT 25 a great commotion in the water. At first they thought it was a rock a- wash about 100 to 150 yards away on the port side, just aft of the bridge, but they soon made out that it was something moving and going slightly faster than the ship, which at that time was doing about 8|- knots. Mr. Simmonds hailed the deck, and one of the crew, who was on the look-out, saw it too. Although there was a bright moon at the time, they could not make out anything of the creature itself, owing to the amount of wash it was making, but they say that from the commotion in the water it looked as if a submarine was going along just below the surface. They both say most em- phatically that it was not a whale, and that it was not blowing, nor have they ever seen anything like it before. After they had watched it for several minutes, it ' sounded ' off the port bow, and they saw no more of it." This creature was an example, I consider, of what has been so often reported, for want of a better name, as the " great sea-serpent." I feel sure, however, that it was not a reptile that we saw, but a mammal. It is, of course, impossible to be certain of this, but the general appearance of the creature, especially the soft, almost rubber- like fin, gave one this impression. It is often said that, if there were such a monster, remains of it would have been found long ago, but this is not necessarily so. Supposing the " sea-serpent ' 26 VOYAGES OF A NATURALIST lives in deep holes, such as there were in the spot where we saw our " monster," then there would be little chance of remains being washed ashore, and the amount of deep-sea dredging that has yet been done is very small, so that it is not surprising that no parts of this creature have been obtained in that way. That it is not more often reported is not to be wondered at, when one realizes how often it is that a ship may sail for days together without sighting another ship, even in seas where there is considerable traffic. Also it must be remembered that such ridicule is generally bestowed on the reports of sea-monsters that many persons hesitate to describe what they have seen. I know myself of several instances of unknown sea-monsters having been seen by reliable witnesses, who, to avoid the inevitable " chaff," would not publicly state their experiences. * * * * The town of Bahia has a striking and picturesque appearance from the harbour, white houses peeping out here and there from luxuriant vege- tation. But " distance lends enchantment to the view," and when on shore the narrow and filthy streets, and the general untidiness of the whole place, quickly dispel the illusion of cleanliness. During my two visits to Bahia I spent as little time as possible in the town. A run of some forty A BRAZILIAN FOREST 27 minutes in our steam launch took us across to Itaparica, where, after passing through a passage in the reef, we landed in a small " Berthon " boat. A great part of the island has been cleared, and it required over an hour's walk to reach the nearest patch of virgin forest. The luxuriance of the vegetation in a Brazilian forest is truly wonderful ; even at mid-day in the thickest part of the forest one might imagine it was twilight, owing to the density of the foliage. Brightly coloured birds and butterflies are met with at every step, and it would seem that in every patch of forest there are different species of birds, while every hour of the day brings forth new forms of butterflies. It was on this island that we first saw humming- birds, a large blue species* being the most abundant. We were rather surprised to notice how frequently these birds perch. I had always accepted it as a general belief that humming-birds seldom settled, but were nearly always on the wing. Since this, my first acquaintance with these ex- quisite little birds, I have had the good fortune to meet with examples of many other species of humming-birds in South America and the West Indies, and have noted that they are as often at rest on the trees as hovering round the flowers in search of food. All the specimens obtained were carefully examined during the process of skinning, * Eupetomena macrura. 28 VOYAGES OF A NATURALIST and in every instance their gizzards contained the remains of insects. During our second visit to Brazil we camped out for four nights ] on Itaparica. Our tent was pitched near one of the patches of virgin forest, and at no great distance from a small lake, on the margins of which were numbers of jacanas,* a bird resembling a water-hen in shape, but provided with toes of such great length, that it can walk with ease over the floating leaves of the water-plants. In the lagoon caimans or alligators were plentiful, and during the day several were always to be found either basking on the trunks of trees, which had fallen near the water, or lying in the water itself, with only their eyes and nostrils above the surface. The near proximity of water to our camp was convenient, but at nightfall we realized that we had made a great mistake, for the mosquitoes swarmed in such numbers that sleep was im- possible. A fire had been lighted previously, and arranged in such a way that the smoke blew through the tent, but the mosquitoes swarmed in notwithstanding, and after spending two nights of discomfort, we obtained mosquito nets and moved the tent to a greater distance from the water. After this we most of us were able to get a couple of nights' immunity from these pests. Two of * Parra jacana. OS Q < CO I— I «i O I— I s ANIMALS OF THE FOREST 29 my companions, however, went out moth-catching at night and omitted to fold up their nets before they started, the consequence being that on their return the nets were full of mosquitoes, and a few weeks later they both suffered from a bad attack of malarial fever. In spite of mosquitoes by night and grass-ticks by day, we all agreed that a short stay in the solitude of a Brazilian forest was a most delightful experience. The first two nights there was sufficient moonlight to make shooting possible, and I spent a great part of the night in walking about round the camp. Several foxes were seen, and one of these I shot. The island abounds with foxes, and there are also a fair number of wild cats, but although several of the latter were seen, we did not succeed in shooting any. Every night I set a number of traps for small mammals, and, though I managed to get a few specimens, I found there were several difficulties to be overcome. In the first place the bait is almost at once devoured by ants, and this necessitates a constant series of visits to the traps. Then again the traps are continually sprung by animals which are too large for them to hold — such as opossums and foxes. Eventually I found that the only way to get any specimens of rats or mice was to set my traps just before nightfall, and then visit them at frequent intervals during the night, and in this way I managed to secure a few. 30 VOYAGES OF A NATURALIST On several occasions we saw troops of marmosets travelling with extraordinary speed from tree to tree through the forest. From our tent a clearing of several acres, with here and there a small clump of mango trees, in which were numerous species of birds, extended to the lake. About the camp itself there were always numbers of vultures of two species.* They showed not the least fear of us, and would descend almost at our feet to pick up scraps thrown out to them. The Brazilians protect these birds, and the penalty for killing one is a heavy fine. Another very com- mon bird of prey is the caracara, a pair of which are to be seen in every patch of forest. We came across a pair of the pale grey variety of this species, and a very beautiful sight it was to see these birds circling round over the tree-tops. In appearance they reminded one somewhat of a buzzard when seen from a distance, but the tail is longer. A large hawkf was also often to be seen sitting on the dead palm trees, and three were shot for the collection, while on several occasions a large eagle was noticed sailing overhead, but never within gunshot. At night the cries of two kinds of owls were noticeable, and these proved to be a small scops-eared owlj and a large wood-owl ; the latter, though seen, was not obtained. Numbers of night-jars of two species inhabited the forest * Cathartes aura and C. atratus. f Aslurina nattereri. J Scops braziliensis. BIRDS OF THE FOREST 31 and clearings near our tent. The cries of these birds, quite unlike the loud reeling note made by the well-known species which we see in England, were loud liquid calls, which were only uttered, so far as I could ascertain, when the bird was on the ground. During the day a scarlet tanager was continually seen in the trees and bushes near our tent, and another bird, most noticeable by reason of its numbers, was a small swallow.* This little brown- backed bird invariably appeared in great numbers directly after a shower of rain. A shower of rain had a remarkable effect on the life in the clearing, for immediately afterwards there appeared immense swarms of flying ants. As soon as these ants arrived, they were followed by a great number of birds of all kinds — flycatchers (Elainea), tanagers, oven-birds, and woodpeckers appeared, while the little brown- backed swallow came in great numbers. The ants were at a disadvantage, and were not safe even when they had reached the ground, for here the woodpeckers followed them and swept them up with their long tongues. I imagine that all these birds came from the neighbouring forests, as previous to the showers of rain not a bird was to be seen in the clearing. Another instance of birds appearing at certain places only when there are insects, was to be * Stelgidopteryx. 32 VOYAGES OF A NATURALIST seen round the lagoon, which a small spine-tailed swift* visited regularly in the evening when there were swarms of small flies, while at other times of the day, when flies were not numerous, not a single swift was observed there. It would be tedious to mention individually all the birds seen during these visits to Itaparica, but there are two other species to which I must draw attention — one, because it is one of the most noticeable of Brazilian birds, and the other, be- cause of its scarcity, as far as specimens in museums are concerned. The first belongs to the family of tyrant-fly- catchers, which is numerously represented in Brazil. Several species were met with by us, but by far the most common was Tyrannus melancholicus — a bird of about the size of a thrush with a yellow breast, grey back, and a partially concealed golden-orange crest. It is to be seen in almost every tree, and is further remarkable for the monotonous cry which it utters continually. The other bird to which I would refer is another member of the family of tyrants. This bird — Myiarchus pelzelni — is apparently scarce in collections, though why this should be it is difficult to say. It was quite common in the mango trees near our camp, and several were shot and skinned. Perhaps, however, Itaparica is particularly suited to its requirements, and it may be rare in other * Chaetura iumosa. A SWAMP 33 parts. I think, however, that most likely it is confused with another bird of the same genus, viz., M. ferox, which is most abundant in Brazil, and closely resembles it when seen at a distance. Every morning, about half an hour before dawn, we left our tent and walked through the woods to a large swamp about a mile away, where we had some fairly good shooting. A large flock of teal* was sometimes feeding on the mud sur- rounding a large pool of water, and a few snipef were bagged, but, unlike snipe in general, they offered the easiest of shots. They behaved much like the jack snipe, rarely flying more than a few yards at a time, and always allowing of a close approach. The most numerous birds were, how- ever, the jacanas, which were in enormous numbers, and as soon as we appeared on the spot they rose in large flocks and circled round us high overhead. Many delightful hours in the early morning were spent in this way among the numerous different forms of bird and insect life. Daybreak in the tropics is undoubtedly the best time out of the twenty-four hours, for then the air is cool and in- vigorating— a great contrast to the rest of the day, when the heat becomes almost unbearable. The hottest part of the morning we usually spent in the thick forest, where, under the deep shade of the trees, it was possible to collect specimens without feeling the effects of the heat. * Nettion braziliensis. f Gallinago delicata. 34 VOYAGES OF A NATURALIST After some experience I have found that the best, in fact the only, time to do really good work in the way of collecting in the tropics, is a few hours after daybreak, and again some two hours before dark. Only then can one work with comfort, but, what is more important, the birds at these times appear to be more numerous and more easily approached. Towards mid-day every sign of animal life seems to disappear, and there is no doubt that at that hour mammals and birds hide away in the comparative cool of the thickest part of the forest. Altogether these few days in camp on Itaparica proved to be most interesting, and although we suffered to a great extent from mosquitoes and grass-ticks, from the latter especially, we were well pleased with our results. The ticks were a source of great annoyance, and, in spite of all we could do to prevent them, they swarmed on our clothing and buried them- selves in our skins. When once fixed in the skin it is a very difficult matter to remove them, as they quickly bury their heads, and if any force is used in removing them, their heads break off and remain in the flesh, where they often cause a bad wound. The part of the island in which we were camped did not appear to be thickly populated. Along the shore there were a number of small houses tenanted mostly by fishermen, but in one or two FETES AT BAHIA 35 of the larger of these houses there were a few of the better-class Brazilians. These were traders from Bahia who rent these houses for the summer, and one of them, who procured porters for us, told us that he took a house on the island every year during the hot weather, as it was then far more healthy than at Bahia. Occasionally a case of " beri-beri " makes its appearance among the natives in Bahia. All sufferers from this dreadful disease are at once sent across to Itaparica, and we were informed that they frequently recover when this is done, but if they remain in Bahia they usually die. The population of Bahia and the surrounding country is of all nationalities, though the greater number appear to be negroes. All these people are of the Roman Catholic religion, and they celebrate their Saints' days by a great display of fireworks. During the two visits of the " Valhalla " there were a number of these displays, and the continual banging of crackers at all hours of the day and night was infinitely less amusing to us than to the Brazilians. On the occasion of our first visit, a great pro- cession of boats filled with priest and choristers started from the shore and visited most of the ships in the harbour. When they arrived at a Brazilian ship they fired off a number of crackers which they had with them, and one of these ships, a Brazilian man-of-war, replied with a salute of guns. On 36 VOYAGES OF A NATURALIST every Saint's day a procession takes place, generally on land, but on special occasions, as on this one, which was the day after Christmas Day, the ships in the harbour are visited. SOUTH TRINIDAD ISLAND, NEAR THE LANDING PLACE. [36.] CHAPTER IV. SOUTH TRINIDAD. At 6 o'clock on the morning of the 3rd January, 1905, the island of South Trinidad was sighted. This island is situated in the South Atlantic Ocean off the coast of Brazil, lat. 20° 23' S., long. 29° 43' W. It is volcanic, and of the same formation as the coast of Rio de Janeiro. South Trinidad had been visited by naturalists three times previously. In 1868 the Italian corvette " Magenta " came to the island, and two species of petrels were obtained and described as new to science by Dr. Giglioli.* The second expedition was made in August, 1875, by Lord Crawford (then Lord Lindsay), who, when on the way to Mauritius to observe the transit of Venus, landed at South Trinidad and made a small collection of birds, f Thirdly, on 13th September, 1901, the naturalists of the " Discovery," when bound for the Antarctic regions, landed there and made a collection. * "Ibis," 1869, pp. 62-60. t "Proceedings Zoological Society," March 2nd, 1880, p. 161. E 38 VOYAGES OF A NATURALIST Amongst the birds obtained by the last-named expedition were several specimens of a petrel, which Dr. Bowdler Sharpe described as a new species.* As we gradually drew near to the island, the " Ninepin," a huge upright column of rock, came into view. This rock is several hundred feet in height, and in shape is much like an enormous tree-trunk. It was at one time undoubtedly of a much large diameter than now, long exposure to the weather having worn its surface away to such an extent that only the hard central core remains at the present time. When we were within a mile or two of the island, we could see that the greater part of it was covered with grass, while against the sky-line at the ex- treme summit a mass of trees could be distinguished. Extending from the summit to the base were many fissures, which formed deep valleys, and these were thickly overgrown with tree-ferns. Sea-birds, chiefly large petrels, appeared in numbers, and circled round the ship, while a good many gannets settled in the rigging. A strong northerly gale was blowing, and Captain Caws had little hopes of the sea being smooth enough to lower a boat. As we drew under the lee of the island, however, the sea proved perfectly calm, and but little surf was beating on the shore. * "Bulletin Brit. Om. Club," XII., p. 49 (February, 1902). TREE-FERNS ON SOUTH TRINIDAD ISLAND. [39.] LANDING ON SOUTH TRINIDAD 39 A large amount of treasure hidden in former days by pirates is said to be buried on South Trinidad, and Mr. E. F. Knight visited the island on two occasions for the purpose of searching for it. We kept a careful look-out for the " Cascade " and the " Pier," mentioned by Mr. Knight in his " Cruise of the Alert." The " Cascade " was soon sighted, and proved to be a small trickle of water which had its source among the groves of tree-ferns near the summit of the island, and ran down a deep valley into the sea at a point about 200 yards from the jutting promontory of black rock which has been named so aptly the " Pier." A boat having been lowered we started for the shore. On getting near in we met with several large turtles, which were swimming about close to the rocks. These turtles visit South Trinidad for the purpose of depositing their eggs, and during our two days' visit we saw many of them swimming about, but none were on the beach, and it is probable that we were too early in the year to find their eggs. The boat was backed up to the natural " pier," and with one of the seamen I scrambled on to the rocks. At first it seemed doubtful whether the " pier " was connected with the shore, but we soon found that it was not difficult to climb over the huge boulders forming the " pier," and thus reach the strip of sand which fringes this part of the island. e 2 40 VOYAGES OF A NATURALIST Directly I had landed I was mobbed by a screaming crowd of white terns and noddies, which rose from their nesting-places on the rocks. So close to me did these birds fly, that I was able to touch them with the barrels of my gun. Between the " Cascade " and " Pier " the coastline is slightly indented and fringed with a narrow strip of sand. Beyond the sand a mass of rocks had to be climbed before we could reach a plateau, which could be seen about 200 feet from the water's edge. After passing the rocky base of the hill, we found the rest of the way com- paratively easy. The ground, which was covered with long wiry grass, was very treacherous, and slid away underfoot at every step. Half-way up the slope the carpenter of the ship planted a board on which " Valhalla " was carved. This board was very thick and heavy, and will probably last for many years. We found the remains of several such boards on the island, but the names they originally bore were all illegible. We found also some letters painted in white on a huge rock on the plateau, but owing to long exposure to the weather this was also illegible. This rock was covered with noddy terns and their eggs. The birds, which were of the same species as the large noddy met with on Saint Paul's Rocks, were very tame, and several photo- graphs of them were taken at close quarters. On the plateau are great numbers of fallen trees, NODDY TERN AT THE NEST, SOUTH TRINIDAD ISLAND. [41.] VEGETATION OF THE ISLAND 41 apparently of a species of acacia, which from all appearances have been dead for many years, though why they died it is impossible to say. They show no signs of having been destroyed by fire. The whole of the island is covered with these dead trees ; some standing with their bare branches spread out as in life, and others lying in all positions. In some places so thickly is the ground strewn with them that it is difficult to force one's way through. When South Trinidad was first discovered it was thickly wooded, but no record seems forthcoming as to when and why the trees died. It mav have been that some volcanic disturbance destroyed all the vegetation, but this seems unlikely, because on the summit of the island there flourish trees and tree-ferns which appear to be of a great age. At one time a number of goats inhabited the island, but for many years these have disappeared, though the reason for this is also unknown. There is at the present time sufficient green food to support any number of goats, for, besides the grass, which covers the greater part, there are quantities of beans growing in masses on the fallen trees on the windward side. As soon as we began to ascend to the plateau numbers of petrels appeared flying overhead ; these were of two species, the most numerous being the (Estrelata wilsoni of Sharpe. About the size of a pigeon, this bird has a dark slate- 42 VOYAGES OF A NATURALIST coloured back and head, with white, or in some individuals grey, underparts. These birds were just commencing to breed in the holes and crannies in the rocks. The other petrel (CEstrelata trini- tatis), which is dark brown all over, with black legs and feet, was less numerous, but higher up the ravine a few were tending their well-grown young, which were sitting in hollows in the rocks and under overhanging ledges. The young birds were covered with long thick brownish-grey down, and resembled big " powder-puffs." They were extremely fat, and when handled they ejected a greenish fluid from their tube-like nostrils. The old birds circled overhead in great numbers and screamed at us angrily. Occasionally a long bubbling note, not unlike the call of a female cuckoo, was heard. This note was only uttered by the Wilson's petrels. The plumage of the birds of this species showed two distinct varieties or " phases." The majority had pure white breasts, but many others had these parts of a smoky-grey colour : these may have been younger birds. I caught many pairs of Wilson's petrels at their nesting-places, and in every case the birds had white breasts, and although I handled a good many petrels (a hundred at least) on South Trinidad, I never found a light- breasted bird in company with a dark-breasted one. It may well be, therefore, that the dark- breasted ones are birds not fully adult. All these P < oc p O « e p "s o 5 P 53 P O CO fc O H O < Ph z x K CO 00 O < TAMENESS OF THE BIRDS 47 plumage of the adult is entirely white, with the exception of a narrow ring of black feathers en- circling the eye. The bill, as I have already noted, is jet black, while the feet are pale sea-blue, the webs joining the toes being milky white. Both old and young have the middle toe furnished with a strong and sharp claw, which is specially useful to the young bird when it is in danger of falling from the nesting place. Several pairs of gannets*, a smaller bird than our well-known solan goose, but somewhat simi- liarly coloured when adult, were found sitting on their nests or tending their young. The nests were in every case a collection of sticks placed in a suitable position on the fallen trees. We found no eggs, but the young were in all stages of growth. The newly-hatched bird is covered with pure white down, but it has a black bill, and a patch of bare black skin surrounding the eyes and extend- ing down the neck under the chin. The down on the forehead stands erect, and gives the bird a most comical appearance. Photographs were obtained of these birds without any difficulty, and most of the old gannets took no notice at all of our presence. In fact, one old bird, which was sitting by a well-grown youngster, took so little interest in our proceedings that we found it necessary to wake it up in order to take its portrait. * Sula piscator. 48 VOYAGES OF A NATURALIST High overhead a number of frigate birds were circling. Every now and again one would plunge downwards and chase a gannet which, slowly flapping up from the sea, was bearing a mouthful of food to its young on the hillside. These frig-ate birds, of which there are two species on South Trinidad, get their food chiefly by robbing the gannets. Woe betide the gannet, as it slowly wends its way to its nest and young, if it is spied by a frigate bird. The robber at once hurls itself on its victim, and the gannet, terrified at the attack of a bird so much larger than itself, drops from its mouth and throat all the fish which it has been at such pains to catch. The frigate bird then swoops down and, catching up the fallen fish before it reaches the ground or sea, makes off and swallows the stolen food at leisure. Frigate birds, however, do not always rely on this method of getting a meal. I have frequently seen them catching fish for themselves, and plunging into the water somewhat after the manner of a tern. I have also seen them feeding on the remains of a shark which had been killed and thrown overboard. The commoner of the two frigate birds on South Trinidad is the greater frigate,* a bird of large size, larger than the common kite, and with a long forked tail. The adult male is a glossy greenish black, the feathers are of a lanceolate shape, and * Fregata aquila. X Z < X z — - H P O x z o o 5* ft O o & p o A z < En hJ- P - FRIGATE BIRDS 49 under the chin is a large red bag, to which I alluded in a former chapter. The bill is long and sharp, and the upper mandible ends with a large curved hook, a most formidable weapon of offence and defence. The females and young have no bag on the throat, and have the underparts white. The other species was the lesser frigate,* which resembles the larger except for its much smaller dimensions. We obtained one specimen, and this was shot from the deck of the yacht by Mr. Lindsay. The lesser frigate bird has only once previously been obtained in the Atlantic. This was on the occasion of the visit of the " Discovery " to South Trinidad, in September, 1901. It is, however, a common bird in the Pacific and Indian Oceans. Apparently neither of these frigate birds was nesting on South Trinidad during our visit, but they may breed on the neighbouring islets of Martin Vas, in the immediate vicinity of which we found them numerous. My great hope was that there might be a land- bird on South Trinidad, because all the other South Atlantic islands, with, of course, the excep- tion of Saint Paul's Rocks, on which there are no trees or vegetation of any kind, have their peculiar forms of land-birds. During the first day we were ashore, I kept to the " Cascade," knowing that there was no time to search thoroughly amongst * F. and. 50 VOYAGES OF A NATURALIST the tree-ferns and other vegetation at the summit of the island. I wished, moreover, to make as complete a collection as possible of the sea-birds, and especially of the petrels peculiar to the islands. In this I was successful, as specimens of all the birds previously known from South Trinidad, as well as of one species — the noddy tern — new to its avifauna, were collected during that afternoon. During the following night we steamed slowly away, and at daylight went about, returning to our former landing place. At 9 o'clock we were ashore again, and at once climbed to the plateau. Mr. Meade-Waldo and I then set off to climb to the summit. We each took a sailor with us to carry our lunch, cameras, and so on, but soon after we had begun the ascent of the " Cascade," one of the sailors gave out, and we had to leave him to return to the ship. After this we had to carry our own cameras, and soon found that these, together with collecting gun, butterfly net, and other things, considerably retarded our progress. After leaving the plateau we decided that our best way to reach the tree-ferns was to follow the " Cascade " as much as possible, and then climb round a huge crown-shaped rock, which towered above us. Passing up the rocky bed of the " Cascade," which I had explored the previous day, we found that beyond it the bed of the stream was somewhat more open. Masses of ferns were growing close to the water, and in these my com- kT " THE "CROWN ROCK, SOUTH TRINIDAD ISLAND. [50 ; WE CLIMB TO THE SUMMIT 51 panion caught a number of moths. The sides of the valley were here very steep and covered with grass, but we soon discovered that the ground was remarkably brittle. We kept to the bed of the stream until the " Crown " rock was reached. The stream here was full of fallen trees, every one of them tenanted by a pair or more of white terns. The trees were lying at all angles, several of them completely blocked our passage, while the sides of the valley were literally covered with dead branches, which lay partly or wholly overgrown by the ferns and grass, so that our progress was extremely slow and tedious. Every now and again a moth fluttered out from under our feet, and many were captured. A little further on the bed of the stream was dry and full of boulders of all sizes, round which we had to make a wide detour. At last we reached the ' Crown " rock, where a halt was made for luncheon. After a too short half -hour's rest we started our climb again, and soon found that we still had the most difficult part of our journey in front, for after we had skirted the " Crown " rock we came to a narrow ridge of crumbling ground. covered with grass but giving no safe foothold. On each side of us the ground sloped down precipitously for several hundred feet, and a slip would have been disastrous. For some distance 52 VOYAGES OF A NATURALIST we proceeded in slow fashion, planting our feet firmly in the crumbling earth, not daring to hold on by the long grass, which would have torn away at once, till at length a broader stretch of land opened in front of us. The ground was still very brittle, but it offered a good foothold. In front of us, at a distance of a few hundred feet, we could see the top of the island covered with low bushes resembling lauristinus, amongst which was a clump of trees bearing shining leaves. In these trees numbers of gannets were sitting on their nests, and they seemed to be considerably astonished at seeing us approaching their home. We quickly scrambled to the trees, and a few minutes later the summit of South Trinidad was gained. I shall never forget the magnificent view which now lay revealed. Behind us was the " Cascade,'" on each side deep valleys filled with tree-ferns, while to our front the whole of the windward side of the island was exposed to view. Immediately below a precipice fell sheer down for several hundreds of feet, and then the land gradually sloped away to the green undulating country which borders the windward side of South Trinidad. In the distance, and close to the water's edge, the remains of a Portuguese convict settlement was to be seen. There appeared to be little of it standing, but the foundations of the houses, deserted for many years past, could be < H Ph Eh H w — w H w Eh O M o Q EH w O 02 A SPLENDID VIEW 53 clearly distinguished. To our immediate right was a peak of about the same height as that upon which we were standing. The ground had slipped away from it to such an extent that all vegetation had been destroyed, and only the deep red-coloured earth was to be seen. Further to the right towered the " Sugarloaf," boldly outlined against the deep blue sea. It was full of crannies and ledges, in which petrels were nesting in vast numbers, As soon as we appeared above the sky- line, these birds left their nests and flew backwards and forwards in immense and continually in- creasing numbers, until the air was full of a screaming multitude of birds. Below, above and on all sides of us these birds wheeled and shrieked, until the clamour became almost deafening. Beyond the " Sugarloaf " we could see " Noah's Ark," a mass of rock rising straight up from the sea, and shaped like the familiar toy so dear to children. This rock was likewise covered with petrels, and they also joined the tumult. At the foot of " Noah's Ark " the pirate's treasure is supposed to be buried. Whether there is really any treasure is doubtful, but if there is, it is probable that it will never be found, as, owing to the brittle character of the soil, the land is continually slipping, so that by this time the treasure must be buried deep, beyond all hope of recovery. Far away, and almost on the horizon, the rocky 54 VOYAGES OF A NATURALIST islets of Martin Vas, on which no one is yet known to have landed, were discernible. It was next to impossible to make our way down to the windward side of the island ; moreover, it was getting late in the afternoon, so we decided that the best thing to do was to descend to the " Pier " by the same way we had come. But instead of taking the " Cascade " valley, we began to descend by another deep valley close to it. The surface of the ground here was even more brittle than in the " Cascade " valley, and the descent was very steep. My companion and a sailor started first and safely reached the first of the tree-ferns. Seeing that they were safely down I started, but the ground was now considerably broken up by their feet, and I found that it was extremely difficult to get a foothold in the powdery red-coloured earth, which slipped away from under me like sand. Suddenly, and without any warning, the whole of the ground gave way, and, enveloped in a cloud of choking dust, I felt myself rushing down the incline, and, before I could realise what had happened, I was standing, or rather sitting, close to my companions. My first thought was for the camera and slides which, together with my gun, had been slung on my back. Most fortunately these were uninjured, and, as I afterwards found, none of the plates had suffered in any way, although the camera-case was full of dust. A VALLEY OF TREE-FERNS 55 After this the way became a little easier. The bed of the valley was dry, but it had evidently been hollowed out by water, for the rocks showed considerable wear from trickling water. Possibly it is only in the rainy season that there is any water in this valley, for at the time of our visit the rocks were covered with a thick tangle of grass. Amongst the grass and climbing over some of the fallen trees, a few of which were to be seen in this valley, was a species of climbing bean. This bean was in flower, and is doubtless the same as that mentioned by Mr. Knight as growing thickly on the windward side of the island. Mention may here be made of some mice which we saw in considerable numbers, both in this and in the " Cascade " valley — to what species they belonged we were unable to determine. They were small and of a greyish colour. We both thought that they looked like a small vole, but they were extremely quick in their movements, and the grass was so thick and high that we were unable to shoot any specimens. The sides of this valley were thickly grown with tree-ferns, and to these we now turned our attention. The ferns were from twelve to twenty- five feet in height. Their stems were quite bare, but at the top a number of fern-like fronds grew at right-angles to the stem. The tree-ferns on South Trinidad grow very close together, and owing to this fact and to the ground being strewn f2 56 VOYAGES OF A NATURALIST with boulders of all sizes, over which the grass had sprung up in great luxuriance, walking through a forest of these ferns was a tedious business. Every now and again I was thrown into a state of excitement on hearing a shrill twit- tering sound just above my head. Visions of a land-bird were always in my mind, but time after time I was disappointed to find that the twitterings were caused by white terns which were nesting on the tops of the decaying trunks of dead tree-ferns. Finally we came to the reluctant conclusion that there is no land-bird of any kind on South Trinidad. We had carefully searched the tallest trees on the summit, and there, as in the tree-ferns, we found no signs of such a bird. On the trunk of one of the tree-ferns, Mr. Meade- Waldo found an orchid, which he sent home to England, but apart from this and the bean there was no other plant in this valley which we had not found in that of the " Cascade." Instead of taking us down to the shore, as we had fully expected, we found that the valley was a mere cul-de-sac, and ended with a steep precipice of several hundreds of feet in height. It was by this time nearly four o'clock in the afternoon, and we had arranged to be at the landing place at five, and here we were nearly two thousand feet above the sea, and the yacht looking a mere speck far below us. It was Q < ■"T" o fel 53 H* fi ^ H <» *e W P S O CO K) H £5 CO 2* eg o 5si fc rt r« s a. i 8 3*. H &5 o H o P3 H ft* -^-^ H W H A DIFFICULT CLIMB 57 necessary, therefore, to get out of the valley in which we were trapped as quickly as possible. To climb the slide we came down was an impos- sibility, my fall earlier in the afternoon having completely shut that way off from us. To descend from where we were was also an impossibility, owing to the precipice. The only way open to us was to force our way through the tree-ferns and gain the ridge and climb up that to the gannets' nests. We all three felt that we had had enough climbing. Water there was none ; all our drink had been consumed earlier in the afternoon. However, we had to get out somehow, and the sooner the better ; so we started off, and at length reached the ridge up which we slowly made our way. Arrived at the top we started for the ' Cascade " valley, and followed the same track as that we had ascended some hours previously. Going down this track was much more un- pleasant than coming up. On our right was a precipice, while the outlook on our left was scarcely less formidable, for in that direction the ground fell away almost sheer for at least three hundred feet. Our path was a narrow ridge, just wide enough to give a foothold, and that a most insecure one. At length, however, we reached the " Crown " rock, and skirting it again we came in sight of the beginning of the " Cascade," the clear water of which was so tempting that the seaman and I resolved to climb down to it. Never 58 VOYAGES OF A NATURALIST was water more refreshing, and not even the presence of vast numbers of land-crabs was suffi- cient to deter us from a long and much-needed drink. Then, feeling greatly refreshed, we fol- lowed the course of the ' Cascade,'3 and little by little made our way down towards the shore. In many places the " Cascade " formed waterfalls as much as ten or twelve feet in height, and these falls were not easy to negotiate. " Jack," however, produced a piece of rope, and so we were able to lower ourselves down from rock to rock, and finally reached the shore without mishap. The sailor who accompanied us on this, and afterwards on many excursions of this kind, was the coxswain of the steam launch, and volunteered to carry our extra baggage, such as cameras and so on. Throughout this voyage he gave his services in this way, and to his untiring persever- ance and willingness we are greatly indebted. We reached the " Pier " about six o'clock in the evening, and for my part I was most thankful to get into the boat and rest. Notwithstanding the hard work, however, I had never spent a more delightful or interesting time. During the three voyages that it has been my good fortune to make in the " Valhalla " with Lord Crawford, many interesting and beautiful islands were visited, but to my mind none of these places possesses the charm of this small uninhabited spot in the South Atlantic. CHAPTER V. MARTIN VAS. The ship was hove to off South Trinidad during the following night, and early next morning we steamed slowly towards the rocky islets of Martin Vas. Owing to the insufficient manner in which the sea surrounding this group of islands has been charted, it was necessary to proceed very cautiously. Suddenly the water became very shallow, and, although we were then about two miles away from the nearest islet, it was necessary to go full speed astern. While we were backing in this way a large rock, covered by some six feet of water, was seen within a few yards of the ship. This rock is not marked on the chart, and we thus had a very narrow escape from an enforced residence on South Trinidad. At length a passage was found for the ship, and we drew in to within about half a mile of the main islet. We then set out in boats and rowed towards the shore. Martin Vas consists of four rocks, the two 60 VOYAGES OF A NATURALIST largest being connected together by a narrow- strip of land which is only noticeable at low water. It does not seem to have been previously mentioned that when approached from the south- east, three of these islets bear a striking resemblance to the outline of South Trinidad, though on a much smaller scale. The largest of them is about 300 feet in height, and its sides are precipitous ; but the summit appears to form a plateau. If the ground of this island is as brittle as that of South Trinidad, I should imagine that it would be nearly impossible to climb to the plateau. No one, however, has, so far as I can ascertain, landed on Martin Vas. It has been said that the heavy surf makes it impossible to land. At the time of our visit, however, the weather was exceptionally fine and the sea quite smooth, and had we been able to spare the time, we could without any doubt have got ashore on the largest of the islets. As we approached numbers of the greater frigate bird appeared and circled overhead. Many sooty terns* also came off from the main islet, and these in company with the common noddy seemed to be the commonest birds inhabiting the group. A few Wilson's and Trinidad petrels were observed, but all these were flying over the sea, either in the direction of, or away from, * Sterna fuliginosa. ffl If i EC < > - O H ■* BIRDS ROUND THE ISLETS 61 Trinidad. None of them seemed to be nesting on Martin Vas. An example of the smaller noddy tern* was seen amongst the common noddy and sooty terns, and a large white-breasted shearwaterf passed my boat. Several pairs of gannets, of the same species as that found on South Trinidad, were also seen, but they did not appear to have nests on Martin Vas. The sooty tern does not seem to have been recorded from Martin Vas or South Trinidad before, though it probably is quite common there. To authenticate our identification a specimen was obtained, and this was the only bird we shot during the morning. I do not think that the islets of Martin Vas are inhabited by any birds of great interest, and probably South Trinidad offers more suitable nesting places. The sea round these islets is inhabited by numerous sharks, almost as many being seen here as at Saint Paul's Rocks. Many were caught from the ship while we were away in the boats, but they were not of any great size, their average length being about six feet. Shortly after mid-day we returned to the yacht, which at once got under steam and left for Tristan da Cunha. During the two days spent on South Trinidad * Micranous leucocapilliis. f Puffinus gravis ? 62 VOYAGES OF A NATURALIST and Martin Vas a large collection of birds was made. They were kept in the refrigerator until I could finish skinning them, a task which occupied several days. The series of skins of the petrels is very interest- ing, and seems to show that Wilson's petrel, which was described as a new species from examples brought home by the " Discovery," is in reality the same as (Estrelata arminjoniana, described many years ago by Professor Giglioli. Owing, however, to the specimens brought home by the naturalists of the " Discovery " being in freshly moulted plumage, they appeared to belong to a different and undescribed species. CHAPTER VI. TRISTAN DA CUNHA. Owing to the very fine weather and light winds the passage from Trinidad and Martin Vas to Tristan da Cunha occupied twelve days. Tristan da Cunha is the largest of a group of three islands, all of which are within sight of one another ; but Nightingale Island and Inaccessible Island, the other two of the group, are insignificant in size and appearance compared with Tristan da Cunha, the peak of which rises over 8,000 feet above the sea. Gough Island, which is situated about two hundred miles to the south and slightly east of Tristan da Cunha, should probably be included in this group, owing to its somewhat similar avifauna. A large number of sea-birds, including several species of albatroses, as well as petrels, breed on Tristan da Cunha and the two smaller islands in the immediate neighbourhood. Long before the islands were sighted sea-birds became very numerous. Two species of petrels 64 VOYAGES OF A NATURALIST which we saw at no great distance from Tristan da Cunha deserve special mention, because up to the present time no one has succeeded in dis- covering where they breed. One of these is the great shearwater,* a well- known visitor to British seas, and I think the only " British " bird whose eggs are now unknown. These birds were seen in some abundance in the neighbourhood of these islands, and in nearly every case there were two individuals, doubtless male and female, together. A few weeks later I ex- amined a skin of the great shearwater in the Cape Town Museum, which had been caught on Inac- cessible Island, and there would seem to be little doubt that this bird breeds on one of these three islands. The other petrel which was encountered, not only before we reached Tristan da Cunha but also between that island and the Cape of Good Hope, was (Estrelata incerta, of which very few specimens have ever been obtained. It is about the size of a large pigeon, and of a dull brown on the back with yellowish-brown, almost golden, neck, and white underparts. The three skins in the British Museum were all obtained in the South Atlantic near the Cape of Good Hope, and possibly this bird also nests on one of these three islands. As the yacht gradually drew nearer to the islands the number of albatroses increased. The * Puffinus gravis. Q Q Ei A MAIL FOR THE ISLANDERS 65 yellow-nosed albatros* was by far the commonest of the three species seen here. This bird somewhat resembles a very large black-backed gull, the head, however, is washed with smoky-grey, and a bright yellowish-orange streak extends along the whole length of the bill. The great albatrosf was in smaller numbers, and most of them left the vicinity of the ship when within a few miles of the island. Every now and then a sooty albatros,J easily recognisable by its sooty-brown colour, was observed. The people on shore soon sighted the ship, and, when we were within a mile of the settlement, two boats put out, and a few minutes later the islanders scrambled aboard. Lord Crawford had brought a mail from England, and some time was spent in sorting the various letters and packages. By the time this was finished it was too late to go on shore that day, and all we could do was to spend an hour in a boat between the ship and the island. I had a talk with several of the islanders about the birds, and especially the three species of land- birds, which have been described from Tristan da Cunha. I succeeded in getting a certain amount of information, but how much of it was correct I cannot say. I was told that there is now only one land-bird. This is a thrush called Nesochicla eremita, which * Diomedea chlororhyncha. f D. exulans. % D- fuliginosa. 66 VOYAGES OF A NATURALIST in colour and size much resembles a young black- bird in nestling plumage. The Tristan finch,* about the size of a sparrow and of a greenish colour, appears to be extinct on Tristan da Cunha, though we were told that it is still common on Inaccessible Island. Tristan da Cunha is overrun with rats, and they are probably responsible for the ex- tinction of the finch. I also made enquiries as to whether the flight- less moorhenf still existed on the main island, but none of the islanders had any knowledge of the bird. They, however, told me that a bird like a " little black chicken " with long legs is quite common on Inaccessible. There is little doubt that this rail, of which I believe no specimens have yet been obtained, is a different species to that which was formerly found on Tristan da Cunha. Moseley statesj that the rail of Inacces- sible Island was described to him by two men who had been living on that island as " much smaller " than Porphyriomis nesiotis, and differing from it in " having finer legs and a longer beak." The name "Inaccessible," it should be mentioned, was given to the island on account of the inac- cessibility of its peak. The island itself, being fringed with a thick growth of kelp weed, is not difficult to land upon, as the weed prevents the surf from breaking on the shore. * Nesospiza acunhae. f Porphyriomis nesiotis. X "Notes by a Naturalist," 1892, p. 105. A NEW DIVING PETREL 67 We rowed to within half a mile of the shore of Tristan da Cunha, near the settlement. The sea was perfectly smooth, and had it been earlier in the afternoon we should have landed. The settle- ment is composed of about sixteen stone houses, and is situated at the foot of the peaks where the grass-covered ground slopes gradually down to the sea. Great numbers of cattle were feeding on this grass land. The islanders sell them to passing ships, and we ordered two bullocks, but owing to the stormy weather which set in that night we were unable to hold any further com- munication with the shore. During the evening I made a small collection of sea-birds. Two fine examples of the yellow- nosed albatros were shot, also some terns.* The latter, which are much like our common tern, were very numerous, and, judging by the number of young birds which were only just able to fly, there must be a considerable nesting colony. The most interesting birds which we saw, however, were some diving petrels, which proved to belong to a hitherto undescribed species, f Superficially these petrels resemble the diving petrel of the Straits of Magellan, but they are somewhat smaller and have a much greater power of flight. On several occasions I saw them rise off the water and fly away out of sight, whereas * Sterna vittata. f Pelecanoides dacunhae Nicoll, "Bull. B.O.C," XVI., p. 103. 68 VOYAGES OF A NATURALIST those found in the Magellan Straits drop into the water after a flight of about fifty to one hundred yards. The Tristan da Cunha diving petrels are constantly exposed to rough weather and break- ing waves, and in consequence have to take wing continually to avoid being drowned, and this fact may account for their greater powers of flight. They were met with soon after we left the yacht, and became more numerous as we ap- proached the land. Half a mile from the shore they were on all sides of us, and appeared con- tinually close to the boat, when instead of diving they at once took to flight, and passed away at a great speed. The peak was covered by a mass of dense clouds, through which there appeared every now and then a yellow-nosed albatros sailing down from its nesting place to the sea. We were informed that a great many of these birds as well as sooty albatroses breed inside the crater at the top of the peak, and that the great albatros does not nest on the main island, but only on Inaccessible. We made arrangements with one of the natives to visit the peak the next day, and had great hopes of making some interesting additions to our col- lection of petrels. Alas, early next morning the sea had risen to such an extent that landing was quite out of the question. We lay to off the island for three days, but the gale increased in fury instead of abating, and as our stock of coal was CLOUDS AND MIST 69 getting very low, we were forced to leave and shape our course for Cape Town. The steward bought from the natives of Tristan da Cunha a quantity of small red berries which, when stewed, were much like cranberries in flavour. This fruit, which we were told formed the prin- cipal food of the thrush-like bird, is probably the Nertera depressa mentioned by Moseley {ibid., p. 99). While the ship was hove to a great many birds were seen, Antarctic skuas and sooty albatroses being the most conspicuous. They were too know- ing or else too well fed to be caught on a hook, although much time was spent in fishing for them. We also saw two very large porpoises, which were nearly pure white ; they played about for several hours round the bows of the ship. During the three days of waiting the weather was so thick that, although we were repeatedly within a mile of Tristan da Cunha, we only twice saw the peak, which suddenly appeared from amongst the clouds and remained visible for several minutes, the rest of the island being com- pletely buried in clouds and mist. G CHAPTER VII. DASSEN ISLAND. Seven days after leaving Tristan da Cunha we sighted Table Mountain, and a few hours later the anchor was dropped in Table Bay. During the week at sea between the Tristan Islands and the Cape we had a strong west wind which was most favourable for sailing, and one day's run under these conditions was 275 miles. During our second day at sea, when nearly 400 miles from Tristan da Cunha, an Antarctic skua and many terns* were met with. These birds must wander many hundreds of miles from land, and, as they were not likely to have been migrating, it is probable that they follow shoals of small fish, and thus in time get into mid-ocean and far from land. Great numbers of petrels and albatroses were also seen, and, indeed, birds were more numerous in this part of the South Atlantic than elsewhere in the oceans that we visited. Petrels of several species were frequent, either singly or in large flocks, while yellow-nosed * Sterna vittata. TABLE BAY 71 albatroses followed us until we were within sight of Table Mountain, when they disappeared, and their place was taken by the " Cape hen."* Table Mountain was quite clear and free of clouds, and the sea was a flat calm as we turned into Table Bay. When we anchored in the Bay, at some distance from Cape Town, we found that cormorants were swarming in incredible numbers right up to the shipping. During our stay at Cape Town the " Valhalla " was dry-docked for scraping and painting, and this necessitated our leaving the ship and taking rooms in an hotel. Eleven days were spent here, and we made several most interesting excursions in company with Mr. W. L. Sclater, who was at that time the director of the Cape Town Museum. Under his guidance we climbed Table Mountain, but by far the most interesting experience was a trip to Dassen Island. This island is situated about 35 miles from Cape Town and is of great importance, not only on account of its fine lighthouse, but also owing to its being a Government " bird-preserve." Cormorants' guano and penguins' eggs are collected on the island in great quantities and shipped to Cape Town. Having obtained special permission to visit the island we left Cape Town on February 3rd in the Government tug "Magnet," which was carrying the * Majaqueus cequinoctialis. g2 72 VOYAGES OF A NATURALIST mails there. Soon after leaving Cape Town we passed close to Robben Island, which is set apart as a leper station. Many penguins were seen during the passage, and numbers of Cape hens followed the launch. Occasionally sooty and black-browed albatroses flew by, but no specimens were obtained as we had no guns with us, on account of the strict regulations enforced on Dassen Island, where the firing of guns is prohibited for fear of disturbing the nesting birds. As we drew close to the island, after a few hours' passage, we came in view of enormous numbers of penguins sitting in rows upon the shore, while the sea in the immediate neighbour- hood was crowded with them. I had never before seen so many birds together, but even this was nothing to what we were to witness the next day. As soon as we landed we were met by one of the lighthouse-keepers, as well as by one of the men whose duty it is to see that the birds are undisturbed. Dassen Island is in no place more than a few feet above the level of the sea ; it is entirely uncultivated, and almost completely covered with a low growing ice-plant. On the windward side the shore is rocky, but in no place steep, while on the leeward side it is sandy. The rest of the island is covered with a deep layer of sand in which the penguins dig holes for their nests at the roots of the ice-plants. » — T '/ cc ft < GO GO CO ft E-t CO H ft H O ft ft co go < W o ^°*^$5?i' w > EifeP'.
