The local headquarters of the industry are at Mergui, but most of the supplies are drawn from Maulmain and Rangoon, or from the more distant Singapore, where the industry is financed. The season extends from October to April or May, when the southwest monsoon begins and puts a stop to the fishery on this exposed coast.
The boats used are mostly of Burmese build. They measure from 25 to 35 feet in length, and 7 or 8 feet in width, and have 18 to 24 inches of draft, with curved or half-moon shaped keels, and with high square sterns. Owing to the very light draft and the amount of free-board, they are deficient in weatherly qualities; but are fast sailors before the wind and are easily rowed from place to place. For this reason they are especially suited to the industry in Mergui, because during the pearling season calms and light winds prevail and oars form the principal motive power, especially in the channels and passageways between the islands where the tides are frequently very swift.
If a number of boats are of the same ownership, a schooner of thirty to one hundred tons’ capacity is commonly provided as a floating station and base of supplies for them; the gathering of such a fleet presents an interesting sight, like a great white hen among her brood of chickens.

Most of the boats are from Mergui, and are chartered at a monthly rate of from Rs.105 to Rs.120 each, including a crew of four or five Burmans with their subsistence, consisting principally of rice and salted fish; the charterer is further required to pay each member of the crew four annas, or one rupee, for each day actually employed in operating the diving pump. In addition to these men, each boat carries one diver and an attendant, commonly known as “tender.” The boat is sailed or rowed by the crew, as directed by the diver; and while the latter is submerged, the boat and crew are under the supervision of the attendant.
The divers are the most important men in the fleet, for on their ability and efficiency depends the success of the enterprise. A very considerable portion of them are natives of the Philippine Islands, although many Japanese have been employed recently, and the number is increasing. The compensation is at the rate of £2 to £4 per month, and £20 for each ton of mother-of-pearl secured. The attendants are likewise mostly Manilamen, but many Malayans and Burmans are employed; the wages range from Rs.50 to Rs.80 per month, including provisions. The peculiar duties of the attendant are to help the diver into his dress, place the shoulder leads into position, screw on the helmet, and especially to receive and respond to signals and to direct the movements of the vessel in accordance therewith.
The scaphander, or diving dress, is composed of solid sheet rubber, covered on both sides with canvas. The head-piece is made of tinned copper, and is fitted with three glasses, one at the front and one on each side, so as to afford the diver as wide a view as is consistent with strength of construction. It has a valve by which he can regulate the pressure of the atmosphere. The dress has a double collar, the inner portion coming up around the neck, and the other hermetically fastened to the breastplate. The breastplate is likewise made of copper. The suit is connected with the air-pump by means of a stout rubber tube which enters the helmet, and through which air is supplied to the diver incased therein. This air-tube consists of three or four lengths—each of fifty feet—of light hose, commonly called “pipe.” This is buoyant so that it may be easily pulled along, and may not readily foul among the rocks. However, when working on very rough bottom with sharp-edged stones, the lower length is of stouter material in order to resist the chafing on the bottom. Before descending, the air-line is loosely coiled around the diver’s arm to prevent a sudden strain on it when it is tightened, and a signal-line is attached to his waist to enable him to communicate with the men above.
In fishing, if the current is slight, the boat is permitted to drift therewith, and if there is little or no current, it is propelled by oars as may be required. The diver—fully dressed in the rubber suit with helmet, etc.,—goes overboard easily by means of a Jacob’s ladder of five or six rungs on the port side of the boat, and is lowered by an attendant, who gives close attention to the lines, the crew having manned the pump in the meantime. On reaching bottom, the diver walks along, following the course of the moving boat and swinging his shoulders from side to side to take in a wide vision in his search for oysters. In clear water he can discover them at a distance of twenty-five or thirty feet, even when fifteen fathoms below the surface; but sometimes the water is so clouded that it may be necessary for him to go almost on hands and knees to see them, and when the seaweeds are thick and high, he may locate them almost as much by feeling as by sight. Owing to this difficulty in seeing the oysters, the work is suspended in rough weather and for many days following. The catch is placed in a sack or basket of quarter inch rope, which is raised when filled, emptied, and returned to the bottom by means of a rope.
