If you want to see a curious sight get a hermit crab some day and pick up half a dozen empty shells of the size to fit him. Lay the shells on the sand in a circle a few inches across, extract the crab without hurting him from his house, and set him down naked among the empty shells. To get him out, by the way, is not so easy as it sounds, but you can do it by taking hold of his claws and maintaining a steady, gentle pull; in time the muscles of his tail will tire and his grip relax. You will be amused when you see his first attempts to walk without his shell, which weighs three or four times as much as the tenant; it is precisely as a man might act, set down on some planet where gravity is weaker than on our earth. Naked, helpless, and worried—très, très inquiet—the crab makes a dash for one of the shells, gives it a hasty inspection with his feelers, finds something not quite right, and hobbles off to the next one. Perhaps this suits him. He faces about, in goes his tail to take a grip on the whorls, he snaps in and out a few times as if trying the strategic possibilities of the new quarters, and next moment you will see him ambling off blissfully toward the bush.
The chase of the hermit crab is tame sport, no doubt, but not entirely without interest. One evening we set out just after dark, bucket and torch in hand—not the old South Sea torch of coconut leaf, but the modern tube of galvanized iron, filled with kerosene and plugged with burlap, which acts as a wick. The high beach is best at this hour, for one's quarry is beginning to emerge from the bush for the evening dip, and those that have passed will leave spoor in the soft coral sand. Here is the track of a small one, winding toward the water in eccentric curves and zigzags; follow it and you find him, motionless in the torchlight, hoping to escape notice. He goes into the pail with a clang—you can hear his feet scratching vainly at the smooth sides. There were not many about on this stretch of beach; they are uncertain in their habits and seem to be great wanderers. Here is the track of a monster, broad and corrugated like the trail of a miniature Whippet Tank; the spoor leads to the lagoon—no signs of him at the water's edge—he has doubled back. Lift up that rotten coconut frond ... an unga, black, hairy, armed with a vicious pair of claws; you can hear him raging in the pail, a noise halfway between a whine and a growl—a crab with a voice!
A stroll of an hour or two along the btuch usually procures enough bait for a day's fishing, and one turns inland to follow the road home. Sometimes, when the new moon has set behind the Avarua peaks and thick darkness settles over the bush—when the surf murmurs almost maudibly in a stillness broken by the plunge of a fish in the lagoon, or the grating screech of a flying-fox, quarreling with his mates in the palm tops—one is not sorry when the lights of the plantation begin to glimmer through the trees.
We went to bed early that evening, for we had to be up long before daylight to catch the first of the flood tide, but these island nights are not meant for sleep—I was soon up again, to spend a couple of hours alone on the veranda. The feel of the air was like a caress; neither hot nor cold, and perfumed with the scents of strange flowers—waxen Tiaré Tahiti, sweet and heady frangipani, languorous Queen of the Night. In the mango tree behind the house a mynah twittered—a drowsy overture to one of their abrupt nocturnal choruses. They are quaint birds, the mynahs; introduced to the Islands many years ago, they have increased amazingly in this friendly environment, where they live in a state of half-domesticated familiarity with mankind. One sees them everywhere, hopping fearlessly about the streets of villages, fluttering to the table to finish the bread crumbs left after a meal, perched on the backs of cattle in the coconut groves. They are intensely gregarious, gathering in large flocks at sunset to roost in some thick-foliaged tree—orange, mango, or alligator pear. From time to time during the night, with an abruptness and perfect unison that make one suspect the presence of a feathered leader of the orchestra, the two or three hundred members of the colony burst into deafening song—a chorus which lasts perhaps twenty seconds, and stops as suddenly as it began.
At last I knocked the ashes out of my pipe and turned in; at intervals, before sleep came, I heard the far-off thud of a ripe coconut, or the faint slither and crash of an old frond, falling from a palm. We were awakened at three o'clock by the cook's announcement that coffee was ready; it is a pleasure to live where dressing is only a matter of slipping on a fresh singlet and hitching the pareu tight about one's waist. Each man carried a pair of old shoes, for even the leathery feet of a native must be protected before he ventures on the live coral. Half a dozen plantation boys followed us to the beach, along a path leading down an avenue of coconuts, the slender boles illuminated by the glare of torchlight. In five minutes we were under the dark ironwoods at the water's edge, where the canoes are hauled up; without waiting for us, the boys plunged into the lagoon—-half swimming, half wading toward the reef—torches held aloft in their left hands.
The tide was very low; we had only a short paddle to the shallow water on the inner side of the barrier. It was dead calm—ideal weather for the spear—but there had been a storm somewhere to the south; lines of tall glassy combers, faintly visible in the starlight, were curling with the splitting reports of field artillery—crashing down on the reef until the coral beneath us seemed to tremble at each shock. The eastern sky had not yet begun to pale—the constellations glimmered with the soft glow of the tropics: the Southern Cross, Orion, and the Pleiades.
When the water was only knee-deep we moored the canoe to a coral mushroom and went overboard in bare legs and tucked-up pareus. Wading slowly, about twenty feet apart—the lagoon so still and clear that it was not easy to tell where air ended and water began—nothing moving in the circle of torchlight could escape notice. It was necessary to watch the bottom and walk warily; the reef is a honeycomb of holes and passages through which the sea boils in at certain tides. Many of these holes, only a few feet in diameter at the surface, lead deep down and out into the caverns lining the edges of the pass—the haunts of octopus and the man-eating rock-cod called tonu. A faint ripple revealed a big blue parrot fish skulking in the shadow of a bowlder; one of the native boys slipped his spear close before he thrust with a skill that needs years to acquire. He killed the fish with a stab just where the head joins the body, and strung it on the strip of hibiscus bark at his waist.
These lagoons swarm with strange forms of life unknown in northern waters; until one learns one's way about there is a certain amount of danger in wading through the shallows along the reef. A sea scorpion passed close by us—a wicked-looking thing, all feelers and enormous fins; a touch of those spines would give you a nasty leg. An even more poisonous fish is found here—though fortunately not often: the noo, which lies buried in patches of coral sand. I have never seen one, and do not know its name in English, but the spines of its dorsal fin are said to be hollow like the fangs of a rattlesnake, and to inject a poison—when stepped on—that is apt to kill or cripple for life. The totara, or sea porcupine, is another odd creature, but not at all to be feared; at the approach of danger he blows himself up like a football, and once inflated, is proof against almost anything—I've seen a man hurl a heavy stone on one a dozen times without being able to burst him open. In a different way, the conger eels are nearly as hard to kill, particularly the big ones, which are no joke to handle when one is wading barelegged. One must be on the alert every moment—torch blazing, spear poised. One moment you jump on a mushroom of coral to avoid a pair of sea snakes, long, slender and spotted—active, fearless creatures whose bite is said to be a serious matter; a moment later you are slipping and scrambling at top speed to cut off some large fish, working his way through the shallows. One of the boys bagged a patuki—a young tonu; I was glad to have a look at the ugly little brute. He was only a foot long—a marvel of protective coloring, irregularly spotted and blotched so as to be nearly invisible against a background of coral. The size of the mouth, the power of the jaws, and the rows of cruel little teeth, convinced me that the full-grown fish must deserve the bad name given him by the pearl divers.
The light was gray and the cloud banks along the eastern horizon flushing pale rose when the boys extinguished their torches and set out across the lagoon, each one trailing a heavy string of fish. My host had had enough sport for once, but I love to be on the water at dawn, so when I had landed him I paddled out to the pass to fish for titiara. The current was slack and not a breath of wind stirred the lagoon. The light grew stronger; the contours of the island developed in sharp serrations against the sky; presently the sun rose.
I anchored the canoe in a fathom of water at the edge of the pass, allowing her to swing out over the depths. Through my water-glass I could examine the precipitous walls of the channel—fifty feet high, overhanging in places, seamed, pitted, broken by the dark mouths of caverns. Shoals of fish moved leisurely along the face of the coral—appearing and disappearing like nesting swallows, seen from a cliff-top: swinish parrot fish, bright blue and long as a man's arm; taputapu, spangled orange and black—stopping to nibble at the coral; slender pipefish; swift nanue; fish of extraordinary form and coloring—indescribable, perhaps undescribed. At last I saw what I was after—a school of titiara, working in from the sea.
