7 oz. 12 dwts. of silver. (See Table of Assay Results and Assay 
Plan, Plate xxv., Plan C.) This sample was found lying on the 
surface, and was probably washed down from a lode. I spent some 
days prospecting for this lode, but was unable to locate Its i 
With regard to Wicklow, a fair chance of testing the gold 
mines valley and Croghan Kinshelagh was not afforded me, 
owing to an objection which the owner of the estate had to 
prospecting, orders being given to those in charge to have me 
turned off and prosecuted if found on the estate. However, 
before being informed of this, I had obtained some samples, 
the highest assay being four dwts. per ton (No. 65, Table of Assay 
Results and Assay Plan, Plate xxiv.). This sample was taken from 
a quartz vein eight inches wide. ‘The length of the outcrop was 
not obtainable ; it is situated near the summit of Croghan Kinshe- 
lagh, and in the immediate vicinity of the old Government workings. 
This I believe to be the highest assay as yet obtained from vein 
quartz in Ireland. The assay was performed in triplicate, the fluxes 
at the same time being assayed and found to contain no gold. 
Tt was the intention of Mr. John Howard Parnell, M.P., and 
myself to erect an experimental washing plant in the vicinity of 
this lode, but permission was refused by the owner of the estate. 
I now beg to refer to the paper contributed by Mr. George H. 
Kinahan “On the possibility of gold being found in quantity in 
Co. Wicklow.”! He states :— 
“ From the explorations in different portions of the world it has 
been learned that in connexion with a Placer mine, gold may be found 
—first, in the mother rock (reefs or veins) ; second, in the higher 
shallow alluvium of the valley (shallow placers) ; third, in the lower 
deep alluvium of the valley (deep placers) ; fourth, in the alluvium 
of the beds of the high, now dry, supplementary streams of the 
ancient or primary valley (dry gulch placers) ; and fifth, in the 
shelves, or high level flats, on the sides of valleys (shelf, reef, or 
bar placers), the latter being the relics or records left of the floor 
of the ancient primary valley—they proving that prior to the 
present time the gold was, in the first instance, deposited in a 
comparatively wide shallow valley, while the alluvium of the 
present stream is the rewashed drift of the ancient valley mixed
