MALAY PENINSULA (Continued) 



occurrence of tin ore, and the manner of mining by Chinese and Malays. Author 

 believes the mining in all of the districts is in its infancy, and with better roads, 

 and the clearing of streams, rendering transportation easier, many of the deposits 

 now neglected could be worked with profit. There is at least 7,680 acres of actual 

 alluvial ground, which under ordinary circumstances, will afford work to 2.5,000 miners 

 for the next hundred years.

Memoir result of seven months exploration in the Malay State of Perak. Perak, 

 although only 95 by 50 miles in dimensions, having an area of less than 5000 square 

 miles, has long been known as a tin producing countrj', but only since the influx of 

 Chinese has it been of first rate importance. Mines worked at present, chiefly alluvial, 

 water-courses being filled with sand and gravel deposits to a depth of 20 or 30 feet, 

 resting upon a floor of pure china clay, apparently derived from decomposition of the 

 granitic rocks. Geological description necessarily imperfect, owing to the dense 

 tropical vegetation which covers the entire country. Author has been able to estab- 

 lish the presence of numerous quartz veins traversing the granite which is coarsely 

 porphyritic in the center and largely charged with tourmaline at the edges of the 

 masses, reproducing the conditions to be found in the northwestern tin districts of 

 Cornwall. Ore very pure, free from wolframite, arsenic, etc., which is troublesome to 

 the Cornish miner. No vein mines have yet been opened. Methods of working, very 

 primitive. Great improvement of mining conditions under British rule.

Description and cost of working the mines of Kuantan, Pahang, the principal lode 

 mine of the Federated Malay States. These mines, so report says, were worked 100 

 years. The open cast sj-stem was the only one adopted by the old miners. Under 

 native management (at least within recent years) the mines were not a financial 

 success. Good outlook for increased output under European management.

 of mining and its difficulties.

" All the ore worked up to the present time has been found in the alluvium 

 derived from the mountain ranges; that is, in mining language, in stream works. 

 The ore has been traced up to veins in the rock, but these have not hitherto been 

 worked. The tin beds are composed of the debris of granitic rocks mi.xed with the 

 ore."
