the granite, the nearest portions of which are three or four miles 

 away. Limestones are however so easily dissolved by water 

 containing carbonic acid that there is nothing astonishing in this 

 denudation. The highest point at which the tin is found is said to 

 be 1000 feet above the present level of the valley. This I did not 

 see. The Malays and Chinese were working in caves 300 or 400 

 feet up the face of the cliff. The ore was sent down in baskets 

 running on wire. 



DlNDINGS. 



At the Island of Pulo Pankore, one of the Dindings Group a 

 small quantity of tin sand is obtained by washing the sand in the 

 valleys. The island is entirely of granite with much red clay on 

 some small hills I did not see any other indications of the 

 paleozoic formation. There are no regular mines. The tin sand is 

 washed from the surface by a few Malays, and smelted in a small 

 charcoal furnace of the rudest construction. The Datu of the 

 locality said that gold was also found in the sand but could not 

 show me any specimens. He brought me however, to a narrow 

 valley about two miles north of the landing place. The spot 

 pointed out was in the bed of a small stream full of large boulders. 

 We washed several panfuls of sand but without seeing a trace of 

 the precious metal. Nevertheless, the Datu insisted that if we 

 would only get some of the sand from under the very large 

 boulders we should find plenty of gold, but as no one had ever 

 done so, this was merely his opinion. It would take a good deal 

 of dynamite to remove even the smallest of the rocks. 



It is very possible that minute scaly gold may be found in 

 connexion with the granite. It is so found at Batang Padang at 

 no great distance to the south-east. It may be also mentioned 

 that the first discovery of tin sand in Australia was made in 

 connexion with gold in the drifts of the Oven's River. Gold in 

 granite is however, rare in Austi'alia, but it is not uncommon, and 

 even rich deposits have been found at the junction of granite with 

 lower paleozoic slates and schists. I believe that at some former 

 time small quantities of gold have been found at Pulo Pankore.
