Estimating the population affected by the trade of Jolo, at 100,000, we note that the importation of cloths and woven materials amounted to ₱204,431 in 1905 and ₱196,836 in 1906, or 37 per cent and 42 per cent of total imports, respectively. There is no doubt that the weaving industry among Sulus and Samals is far from being adequate to furnish clothing material, and European cotton cloths are therefore extensively used throughout the Archipelago.
The importation of rice amounted to ₱152,344 in 1905 and ₱114,832 in 1906, or 27 and 24 per cent of the total imports, respectively. The Sulus are agriculturists and should be able to raise sufficient rice for themselves and the Samals. The islands most fitted for this purpose are Sulu, Basilan, Tapul, Siasi, Pata, and Pandami. The Samals are not agriculturists as a rule and seldom raise anything except tapioca and corn. They generally live on flat, low islands, unfit for the cultivation of rice. The Archipelago as a whole should produce sufficient rice, tapioca, corn, and camotes to feed the whole population. The importation of rice in 1905 was probably in excess of the average amount; less rice was raised that year because of war and general disturbances.
The commodities of next importance are yarn and thread for weaving purposes. Importation of these articles amounted to ₱36,118 in 1905 and ₱39,188 in 1906, or 7 and 8 per cent, respectively. The country does not produce silk, cotton, or wool.
All other imports may be regarded as accessories. Of these opium comes first, then dyes, breadstuffs, sugar, iron, steel, brass, paper, and earthenware. A considerable amount of tobacco is imported by the government free of duty, and quantities of tobacco, opium, and cloths formerly were smuggled in. The reduction of imports in 1906 may be due to increased production, to the depression that followed the disturbances of 1904 and 1905, and to a diversion of certain parts of the trade to Zamboanga.
The exports, on the other hand, show a light increase in 1906. They distinctly represent those resources of the country which are most capable of development. At the head of the list stands the shell industry, particularly the pearl shell, which amounted to ₱189,472 in 1905 and ₱149,542 in 1906, or 64 and 52 per cent of total exports, respectively. The exportation of shell has lately been greatly affected by the falling of the price of pearl shell in the market of Singapore. The exportation of other shells seems, on the contrary, to have increased. Pearl fishing is the principal industry of the country and forms the main source of its riches. The fishing is done exclusively by natives, but the trade seems to be wholly in the hands of Chinese. The figures given above do not include pearls. It is very difficult to obtain any statistics for this valuable product, but on the whole it is reckoned by merchants as equivalent to the whole output of shell.
Second in importance comes copra, which amounted to ₱35,740 in 1905 and ₱60,104 in 1906, or 12 and 21 per cent of total exports, respectively. The marked increase of this export in 1906 may be explained partly by increased production and partly by the general damage done to the trees in 1905 by locusts. Increase in the cultivation of coconut trees is not perceptible and can not account for the increase in exportation.
Dried fish comes third in order, amounting to ₱15,786 in 1905 and ₱26,302 in 1906. This industry is capable of unlimited development. The fertility of the Sulu Sea is unusual and can hardly be surpassed. Nothing but enterprise and organized effort is needed to render this trade a source of enormous wealth to the country. The natives are exceedingly skillful in fishing, but lack ambition and initiative. The trade in fish is mostly in the hands of Chinese merchants.
Fourth in importance comes hemp. Both in fiber and cordage its exports amounted to ₱11,140 in 1905 and ₱21,230 in 1906. Hemp culture has markedly improved during the last year, and the increased production is sufficient to explain the increase in exportation. Coconut trees and hemp grow splendidly on all the larger islands of the Archipelago, and their cultivation is capable of extensive development.
Copal and gutta-percha are the products of Sulu, Basilan, and the Tawi-tawi Islands. Although sufficiently important in themselves, they sink into insignificance when compared with the four primary staple products and the immense possibilities that lie in the line of their development.
The greater part of the trade of Jolo is handled by the Jolo Trading Company, the firm of Hernandez & Co., and the commercial houses of Chaun Lee and Ban Guan, all of which are controlled and managed by Chinese merchants. The following list compiled in the office of the Jolo Trading Company, for the Far Eastern Review, is a fair estimate of the prospective exports of the town for the coming two years:
| Article | Amount | Price | Total |
| Piculs. | |||
| Hemp | 1,000 | ₱21 | ₱21,000 |
| Pearl shells | 150 | 45 | 6,750 |
| Trepang or beche-de-mar | 50 | 30 | 1,500 |
| Shark fins | 20 | 45 | 900 |
| Hemp rope | 30 | 25 | 750 |
| Caracoles (sea shells for buttons, etc.) | 40 | 12 | 480 |
| Black shells | 10 | 8 | 80 |
| Copra | 500 | 7 | 3,500 |
| Seaweeds | 40 | 4 | 160 |
| Hides | 10 | 20 | 200 |
| Cacao | 10 | 50 | 500 |
| Tortoise shells | 1½ | 1,800 | 2,700 |
| Sea horses | 240 | ||
| Grand total | 38,760 |
Hemp is generally exported to Manila, while the other articles mentioned in the above table are generally exported to Singapore.
Trepang, shark fins, seaweed, and sea horses are foods highly prized by the Chinese.
If the value of pearls taken is estimated on the basis suggested by the president of the Jolo Trading Company, it will bring the total up to ₱58,760 per month.
Population
The present population of Jolo is less than 2,000. This includes all the natives and foreigners living in Tulay and Busbus; but the United States troops are excepted. The bulk of the inhabitants is made up of Filipinos,
