Otf THE PATANI. 137 



but during long and careful observations, extending over a period 

 of fourteen months, I did not find any traces of galena veins in 

 granite itself. I found, however, that there existed a distinct 

 mineral band or belt, about two miles in width striking south and 

 by west, and within this belt, these veins of galena were frequent, 

 whilst the largest and most productive lodes, although each series 

 was broken and disconnected by the intervening granite, were 

 found running in one straight and clearly defined line in the same 

 direction, although not necessarily having all the same direction of 

 strike, the contortions of the limestone causing the same lode to 

 assume different bearings according to the displacement of the 

 rock. 



If the reader will glance at the rough sketch map, he will note 

 to the north in the Goa Tumbus Valley the words " Great Lode ;" 

 this is a wide strong lode of lead with copper and iron pyrites, and 

 extends downwards into the shales which exist at this place ; from 

 thence draw a line to " No. 3 " which is in the limestone on the other 

 side of the intervening granite, this is also a strong lode of the 

 finest galena, not yet traced to shale, but cased in crystalline lime- 

 stone ; from thence again in the same direction draw a line to the 

 place marked " Kim Ching Valley " and here again occur numerous 

 veins of galena whilst a hill of granite intervenes between this 

 limestone and that of No. 3. Galena is also found on the opposite 

 valley in the same direction, granite again intervening. 



Further to the north-west in the valley of Goa Tumbus draw a 

 line from the point where a large lode is marked as cropping up 

 in the stream, this is also more or less in shales and highly impreg- 

 nated with pyrites ; now draw a line from this in the same direction 

 as the previous one and it will be found to cut the point marked 

 " No. I Mine," which was the largest lode of galena that has ever 

 been discovered in Malaya and of first quality ; continue the line 

 again and it strikes at the head of the Kim Ching Valley where a 

 series of rich lodes exist to the present day. I may remark that 

 these lodes occurring in the crystalline limestones contain silver in 

 proportions varying from 23 to 66 oz. to the ton. 



The tin deposits which in this part of the country are mostly 

 worked on the hills, will also be found more or less to follow the
