232 ON THE DETRITAL TIN-ORE OF CORNWALL. 
As the earlier accounts show that tin was obtained in this dis- 
trict and in its neighbourhood in much larger quantities than in 
any other part of Cornwall,* it might have been expected that 
traces of works still more ancient would have been more numerous, 
and masses of Jew’s-house-tin more frequently found. If it were 
so, however, they probably found their way to the Smelting- 
furnace at once; for the interest of Antiquaries and Mineralogists 
in their preservation was, at that time, but slightly aroused. As, 
for many years past, din-str eaming has had but a bare existence in 
the vicinity, neither specimen, nor record of discovery,t has 
rewarded later enquirers. 
‘*The present Mr. Glynne of Glynne has...shown me a large gold 
‘“‘ Seal-ring made of Gold hoppes found in the River under his house ” [Mr. 
Tonkin’s papers MS. B: pa: 54]. ‘I have also Two small pieces found in 
a ‘* Stream-work near the Church of Cardynham not far from Bodman.”

+ At Berriow in North Hill the ruins of an old building—always known 
as the Jew’s-howse—were remoyed about 1832-3, and beneath them were 
found— 
a ladle of stone [? potstone] now in the Museum of the Royan InsrirurTion 
OF CoRNWALL; and two troughs or moulds of granite, which measured re- 
spectively— 
The smaller. The Larger.
