in argillite. The source of the gould was thus made evident. 
At the Centennial Exhibition, Philadelphia, 1876, H. S. Poole, 
Superintendent of the Acadia Mine, Pictou, exhibited a collec- 
tion of gold specimens with associate minerals. In this there 
were fine specimens of the gold containing conglomerate of 
Gay’s River. One large specimen was particularly interest- 
ing. It is a large piece of greenish argillite upon which con- 
glomeiate has rested, leaving a small portion of itself and a 
striking display of small plates and scales of gold. On our last 
visit to the mines I found that a great amount of work had been 
done since my previous visit. The slates underlying the con- 
glomerates had also been excavated. I did not find any con- 
glomerate with gold, but I observed in the slates abundance of 
the Discinoid forms, which had attracted my attention on my 
first visit, and which I have already noticed elsewhere. These 
forms here are very regular, striking and puzzling. The 
specimens in the Museum with the gold containing conglomerate 
readily attract attention. The sea shore of the Lower Carboni- 
ferous Period extended to the position of Gay’s River Gold 
Field. 
The gypsums associated with the conglomerate are seen by 
frequent outcrops to extend westward to the neighborhood of 
the Gay’s River and Shubenacadie Road. Beyond this all for- 
mations are obscured, except on the old road from Gay’s River 
to Elmsdale. Here frequent outcrops of Lower Cambrian 
quartzites occur. Beyond the road to Milford these are seen to 
approach the Shubenacadie River to within the distance of 4a 
mile. Before coming to Elmsdale they retreat in the direction 
of the Oldham Gold Mines, giving place to a large extent of 
eypsums and gypseous deposits. Near the Enfield Station, on 
the other side of the Shubenacadie Bridge, on the road to the 
Oldham Gold Mines, argillites appear. About 2 miles farther 
we-enter the mining region. I visited these in order to examine 
the position where our rich gold specimens had been found—the 
specimens which had been purchased by the Government for 
exhibition at the Centennial Exhibition, Philadelphia. I exam- 
ined the position with interest. Jt was in the Oakes’ Mine, at
