[A stolen granite monument.] In walking about the parts of the town we were permitted to enter, large slabs of cut granite were seen, which were presumed to be from China, where the walls of canals or streamlets are lined with it.  But Dr. Pickering in his rambles discovered pieces that had been cut as if to form a monument, and remarked a difference between it and the Chinese kind.  On one or two pieces he saw the mark No. 1, in black paint; the material resembled the Chelmsford granite, and it occurred to him that the stone had been cut in Boston.  I did not hear of this circumstance until after we had left Sulu, and have little doubt now that the interdiction against our gentlemen visiting some parts of the town was owing to the fear they had of the discovery of this plunder.  This may have been the reason why they so readily complied with my demands, in order to get rid of us as soon as possible, feeling themselves guilty, and being unprepared for defence; for, of the numerous guns mounted, few if any were serviceable.

The theft of the pistol was so barefaced an affair, that I made up my mind to insist on its restoration.  At the setting of the watch in the evening, it had been our practice on board the Vincennes to fire a small brass howitzer.  This frequently, in the calm evenings, produced a great reverberation, and rolled along the water to the surrounding islands with considerable noise.  Instead of it, on this evening, I ordered one of the long guns to be fired, believing that the sound and reverberation alone would suffice to intimidate such robbers.  One was accordingly fired in the direction of the town, which fairly shook the island, as they said, and it was not long before we saw that the rogues were fully aroused, for the clatter of gongs and voices that came over the water, and the motion of lights, convinced me that the pistol would be forthcoming in the morning.  In this I was not mistaken, for at early daylight I was awakened by a special messenger from the Datu to tell me that the pistol was found, and would be brought off without delay; that he had been searching for it all night, and had at last succeeded in finding it, as well as the thief, on whom he intended to inflict the bastinado.  Accordingly, in a short time the pistol was delivered on board, and every expression of friendship and good-will given, with the strongest assurances that nothing of the kind should happen again.

[Marongas island.] As our naturalists could have no opportunity of rambling over the island of Sooloo, it was thought that one of the neighbouring islands (although not so good a field) would afford them many of the same results, and that they could examine it unmolested.  Accordingly, at an early hour, they were despatched in boats for that purpose, with a sufficient guard to attend them in case of necessity.  The island on which they landed, Marongas, has two hills of volcanic conglomerate and vesicular lava, containing angular fragments embedded.  The bottom
