I asked him how the people of Kusaie first became acquainted with the properties of the plant. He shook his head.

“I do not know. God made it to grow here in Kusaie in the days that were dark” (heathenism) “and when we were a young people. A wise man from Germany was here ten years ago, and he told us that the people of Ponapé, far to the west, use the oap even as we use it, but that in Ponapé the plant grows larger and is more juicy than it is here.” *

* The “wise man from Germany,” I ascertained a year or two
afterwards, was the well-known J. S. Kubary, a gentleman
who, although engaged in trading pursuits, yet enriched
science by his writings on his discoveries in Micronesia.

Early on the following morning, when the tide was falling, and the jagged pinnacles of coral rock began to show on the barrier reef opposite the village, the entire population—about sixty all told—were awaiting Kusis and myself outside his house. The men carried small, unbarbed fish-spears, the women and children baskets and bundles of oap.

From the village to the reef was a distance of two miles, which we soon covered by smart paddling in a dozen or more canoes; for had we delayed we should, through the falling tide, have been obliged to leave our stranded crafts on the sand, half-way, and walk the remainder.

I need not here attempt to describe the wondrous beauties of a South Sea coral reef at low tide—they have been fully and ably written about by many distinguished travellers—but the barrier reef of Strong's Island is so different in its formation from those of most other islands in the Pacific, that I must, as relative illustration to this account of the fishing by oap mention its peculiarity.

Instead of the small clefts, chasms, and pools which so frequently occur on the barrier reefs of the mountainous islands of Polynesia and Melanesia, and which at low tide are untenanted except by the smallest varieties of rock-fish, here were a series of deep, almost circular, miniature lakes, set in a solid wall of coral rock with an overlapping edge, which made the depth appear greater than it was, especially when one stood on the edge and looked down to the bottom, four to six fathoms below.

In all of these deep pools were great numbers or fish of many varieties, size, and colour; some swimming to and fro or resting upon the sandy bottom, others moving upwards and then downwards in the clear water with lazy sweep of tail and fin. One variety of the leather-jacket tribe was very plentiful, and their great size was excelled only by their remarkable ugliness; their ground colour was a sombre black, traversed by three broad bands of dull yellow. Some of the largest of these fish weighed quite up to 20 lbs., and were valued by the natives for their delicacy of flavour. They would always take a hook, but the Strong's Islanders seldom attempted to capture them in this manner, for their enormous, hard, sharp, and human-like teeth played havoc with an ordinary fish-hook, which, if smaller than a salmon-hook, they would snap in pieces, and as their mouths are very small (in fact the leather-jacket's mouth is ridiculous when compared to its bulk), larger and stronger hooks could not be used.

Another and smaller variety were of a brilliant light blue, with vivid scarlet-tipped fins and tail, a perfectly defined circle of the same colour round the eyes, and protruding teeth of a dull red. These we especially detested for their villainous habit of calmly swimming up to a pendant line, and nipping it in twain, apparently out of sheer humour. Well have the Samoans named the leather-jacket Isu'umu Moana—the sea-rat.

In one or two of the deeper pools were red, bream-shaped fish that I had in vain tried to catch with a hook, using every possible kind of bait; but the natives assured me that I was only wasting my time, as they fed only upon a long thread-like worm, which lived in the coral, and that a spear or the oap was the only way of capturing them. So far I had never actually handled one, but on this occasion we secured some dozens. Here and there we caught sight of a young hawk-bill turtle darting out of sight under the ledge of the overhanging walls of coral, putting to flight thousands of small fish of a score of shapes and colours.
