which, however, are not disposed parallel with the coasts, but run in a transverse 

 direction towards the south-west, one of them terminating in the granite headland 

 of Cape Mandhar. Farther south rises the isolated mass of Dikbuik, better known 

 by the name of Bonthain, or Bantaeng, from the town at its foot. Bonthain, 

 which was found by Weber and Wich- 

 mann to be of volcanic origin, as already 

 suspected by Beccari, is the culminating 

 point of Celebes (10,270 feet). 



The south-east corner of the Macassar 

 peninsula is continued seawards by a few 

 islets and the long, hilly island of Salayer 

 (Saleyer), or Limbangang, with heights ex- 

 ceeding 3,000 feet, and at one point attain- 

 ing an altitude of 5,840 feet. A curious 

 and hitherto unexplained phenomenon is 

 the glow of light observed in the evening 

 at both extremities of Salayer during the 

 prevalence of high winds. Salayer is itself 

 continued southwards by other islets, such 

 as Tambolongang, Pulasi, Rusa, Tanah 

 Jampea, and Bonerate, which belong ad- 

 ministratively to Celebes, and which like 

 Buton, at the extremity of the south- 

 eastern peninsula, may also be regarded 

 as forming part of the same geological 

 system. 



Although no volcanoes have been dis- 

 covered in the central parts, there can be 

 no doubt that in remote times Celebes was 

 the scene of considerable eruptions. In 

 several districts, and especially near Maros, 

 in the province of Macassar, the limestone 

 formations rest on basalt rocks, which here 

 and there even crop out above the sedi- 

 mentary deposits. 



The northern peninsula, attached to the 

 rest of the island by a low, narrow isthmus, 

 forms geographically and geologically a dis- 

 tinct region. East of Tomini, where the 

 isthmus is contracted to a width of about 18 

 miles, and commanded by the lofty Mount Donda (9,500 feet), the peninsula is 

 traversed by chains of gneiss and auriferous quartz hills, and at the point where 

 it trends towards the north-east more recent lavas and scoriae have burst through 

 the other formations. Here rises the Saputan volcano (6,170 feet), the theatre of
