If you will turn to the map you will see that Torres Strait, which separates Australia from New Guinea, is spotted with islands. There are hundreds of them, some inhabited by strange tribes and others sparsely settled by Australians. There are islands for every day of the week, and when we came into the harbour of Thursday Island we were told we must go on to Friday Island for quarantine.

Thursday Island is scarcely more than a tiny speck in Torres Strait, but owing to its excellent harbour it is a port of call for ships on their way through the passage. All the steamers that go about north Australia to Europe stop here. There are also steamers for Japan, China, the Philippines, and other parts of Asia, as well as vessels bound for New Guinea and the islands of the South Seas.

The island has a military importance, as it commands Torres Strait and is one of the defences of the British possessions in this part of the world. The harbour is large enough and deep enough for the biggest warships; it has been strongly fortified and has also a coaling station.

Through its commerce and pearl fisheries a considerable town has grown up on the island. Two piers have been built out into the harbour for the accommodation of the smaller steamers, and back of these are the warehouses and stores. There are six hotels, three or four churches, and the large house of the governor, who is a Queensland official. This stands on a little hill at one end, not far from the barracks, great two-story buildings with galleries around them, looking not unlike one of our second-class summer hotels.

The port has one of the most mixed populations of this part of the world. I had no sooner stepped on the wharf than I was surrounded by representatives of all the peoples of the South Pacific. There were brown men, black men, and yellow men; Filipinos, Japanese, Chinese, East Indians, Fijians, Papuans, and Australian aborigines. There were pearl divers, beachcombers, bêche-de-mer fishermen, and adventurers of all colours and races. Thursday Island is a sort of Suez for an area of nearly twenty thousand square miles of island-sprinkled ocean between New Guinea and Australia. The town itself is far cleaner than many of its population, being quite free from epidemics, for the Queensland government rigidly enforces the health regulations. Native councillors elected by the people must see that the villagers keep their houses, food, and clothing clean, that they go regularly to church, and that they send their children to school. These black officials strut about in red jerseys with the word “Councillor” in white letters across the front.

The chief interest in Thursday Island lies in its pearl fisheries. Pearls and shells are the principal subjects of discussion, and the finding of a large pearl is talked of everywhere. The best pearl shells are taken from the coral islands and lagoons. The oysters grow to an enormous size, often having shells as big as a tin wash basin. The average weight of a pair of shells is about two pounds. The oysters lie on the bottom of the sea or cling to the coral rocks. They do not like sand or mud, and will not thrive where the tide shifts the bottom about. They grow largest where they can fasten themselves to coral formations. There are many caverns in the reefs, and the oysters attach themselves to the roofs of these submarine caves in clusters of a dozen or more. They cling to the rocks by a cartilage, or muscle, that extends out near the hinge of the shell, and then branches off into multitudinous threads, each of which glues itself to the rock.

Several years ago a perfect pearl, weighing thirty-two and a half grains and valued at five thousand dollars, was taken out of the Thursday Island grounds. But this was a rare find, indeed, for most of the money in getting pearl oysters comes from the shells and not from the occasional pearls within them. It is estimated that only one shell in a thousand contains a pearl. In a recent year the value of Australia’s export of pearl shell was nearly two million dollars, while the value of the pearls shipped in the same year was only about one sixth as much.

Shell is cash at Thursday Island, and in the world’s markets the better quality commands from five hundred to a thousand dollars a ton. It is used for making mother-of-pearl knife handles, buttons, and in all sorts of inlaid work. Trading vessels sail from island to island collecting the shell from the natives, in exchange for tobacco, calico, and other goods. The traders pay from sixty to one hundred dollars per ton for shell that will sell in London for about ten times as much.

The Japanese have almost monopolized the diving at Thursday Island, for they will stay longer under water and risk more than any one else. Among the divers are also many South Sea Islanders, besides Danes, Swedes, and Malays. The proprietors of the pearl ships say the Japanese are the best, and that the others often pretend to be sick.

The fishing is done by fleets consisting of one large boat, of, say, one hundred tons, and several smaller ones. The divers work from the small boats, each of which has a pump to supply them with air when they are under the surface. As even the small boats cost several thousand dollars each, the business takes considerable capital. The diver prepares for his plunge by slipping on over heavy flannels a diving suit to which ropes and air tubes are attached. He wears a metal helmet with circles of glass set in it so that he may see about him. His boots are soled with plates of copper or lead weighing about twenty-eight pounds to each foot, while the total weight of his equipment may be more than one hundred and fifty pounds.
