Caution is never laid aside, the only law that exists being that of force; but the weak contrive to balance the power of the strong by uniting. They have not only contentions and strife among themselves, but it was stated at Manilla that the mountaineers of Sooloo, who are said to be Christians, occasionally make inroads upon them. At Sooloo, however, it did not appear that they were much under apprehension of these attacks. The only fear I heard expressed was by the Sultan, in my interview with him; and the cause of this, as I have already stated, was probably a desire to find an excuse for not affording us facilities to go into the interior. Within twenty years, however, the reigning Sultan has been obliged to retire within his forts, in the town of Sooloo, which I have before adverted to. These people are hostile to the Sooloos of the coasts and towns, who take every opportunity to rob them of their cattle and property, for which the mountaineers seek retaliation when they have an opportunity. From the manner in which the Datu spoke of them, they are not much regarded. Through another source I learned that the mountaineers were Papuans, and the original inhabitants of the islands, who pay tribute to the Sultan, and have acknowledged his authority ever since they were converted to Islamism. [67] Before that time they were considered extremely ferocious, and whenever it was practicable they were destroyed. Others speak of an original race of Dyacks in the interior, but there is one circumstance to satisfy me that there is no confidence to be placed in this account, namely, that the island is not of sufficient extent to accommodate so numerous a population as some ascribe to it. The forts consist of a double row of piles, filled in with coral blocks. That situated on the east side of the small stream may be said to mount a few guns, but these are altogether inefficient; and in another, on the west side, which is rather a rude embankment than a fort, there are some twelve or fifteen pieces of large calibre; but I doubt very much if they had been fired off for years, and many of the houses built upon the water would require to be pulled down before these guns could be brought to bear upon any thing on the side of the bay, supposing them to be in a good condition; a little farther to the east of the town, I was informed they had a kind of stockade, but none of us were permitted to see it.
