The experiments were conducted on quartz obtained from 
the Clogau mine, 1 cwt. of which was crushed and tested, 
producing eight ounces and five pennyweights of fine gold., the 
value of which is rather more than £3 per ounce. 
From the same mine had also been produced 207 tons of 
quartz, 191 of which gave 241 ounces; 12, of better quality, 
gave 96 ounces; and 3 tons of best quality the enormous 
amount of 976 ounces : the whole quantity amounting to 1,314 
ounces. This, together with an experiment on five tons a little 
before, yielded a total of 1,370 ounces, valued at £5,300 ; the cost 
of obtaining which he estimated at £300. There are, of course, 
exceptional cases, but sufficient to show what may be done ; 
though, taking the bad with the good, Mr. Readwin considers 
half an ounce of gold to the ton of quartz to be the average 
yield. The total proceeds of gold for the last Christmas 
quarter amounted to £4,796, which lie expects will be the 
average quarterly yield for the present year. With these 
results, we are surely justified in considering gold-mines as 
one of the staple products of our island : not to be looked upon 
as a treasure for fortune-seekers wherewith to indulge the 
ff auri sacra fames,” but, like all other mining ventures in 
this country, as another opportunity for the application of 
steady perseverance combined with the highest scientific know- 
ledge and application.
