This must have come from some quartz reefs further up in 

 the hills. Its occurrence in this river is referred to in the 

 Kadayim-pota. 



A second instance of its occurrence in this form was in the 

 Galle District, where a small nugget was taken from the alluvium 

 accumulated in one of the ravines ; it weighed over 6 grains, 

 and was associated with fragments of gems, such as sapphire, 

 garnet, chrysoberyl, tourmaline, zircon, as well as of sulphides 

 of some rare metals. This deposit was due to disintegration 

 from the matrix in which they occurred originally. I followed 

 up the ravine to its head with the expectation of finding a 

 quartz reef from which the gold must have been dislodged, and 

 found two small reefs crossing it. I took specimens from 

 these and found traces of gold, but not in sufficient quantity to 

 warrant its being worked. I have had further specimens from 

 this reef of a much better character. 



In the second form it occurs in the Ramboda district, Central 

 Province, where several remarkable reefs strike across the 

 valleys. In one of my tours I gathered numerous specimens 

 of quartz of various hues, chloritic and micaceous rocks. 

 On breaking them up and examining, I found in the quartz traces 

 of gold, a specimen of which is on the table. I am unable to 

 give the precise locality. 



In the third form it occurs in the pyrites of the gem-pits in 

 the Ratnapura-Rakwana districts, but only in very small 

 quantity. 



From the little I have seen, it is my opinion that considerable 

 quantities will yet be brought to light. 



Specimens exhibited. 



1. Nugget of gold. — Galle District. 



2. Associated Minerals of ditto. 



3. Gold in quartz. — Central Province,
