XI. Meanwhile gold jnlly be looked for in 
Perthshire chiefly ik the following 
LOCALITIES OR UNDER THE FOLLOWING CIR¬ 
CUMSTANCES :— 
A. At the head-waters of the rivers or streams ; 
in the ravines of mountain water-sheds. 
It must he remembered that the largest nuggets 
are to be expected nearest their matrix ; and the 
proximity of that matrix may be judged of by the 
angularity or smoothness of their surface —• the 
smoothest being the most water-worn and the 
furthest travelled. 
B. In ‘‘drifts’' (gvavels, clays, sands)—at their 
base—especially where they rest on the 
“ bed-rock, ” and in “pockets” or hollows 
of the latter. 
The fullest and most recent information concern¬ 
ing the “ Gold and GokbFields of Scotland,” includ¬ 
ing those of Perthshire, is to be found in three papers 
by the author—the first submitted to the Geological 
section of the British Association in 1867, and pub¬ 
lished in the Beport of the said Association for that 
year; the second presented to the Geological 
Society of Edinburgh in 1867, and published in its 
Transactions for 1868 ; and the third read before the 
Ptoyal Geological Society of Ireland in 1868, and pub¬ 
lished in its Journal for 1869. 
My mineral cabinet contains several specimens of 
Scottish native gold, collected for me in one of the 
southern auriferous counties of Scotland some years 
ago, or sent recently from the Sutherland diggings; and 
it will give me pleasure to show them to any person 
exhibiting a hona fide interest in the present subject. 
Though intended, doubtless, to convey b, figurative 
meaning, the following quotation from Bernard is 
quite appropriately applicable to m}^ present subject 
in a very literal sense :— 
Men’s books with heaps of chaff are stored : 
God’s Book doth golden grains afford. 
Then leave the chaff, and spend thy pains 
In gathering up the golden grains !” 
A vote of thanks was awarded to Dr Lauder 
Lindsay for his paper.
