The world seems to be finding new treasures every day.

It -seems certain that the Cape diamond field is one of extraordinary Tichness, and covers a tract 500 miles long, and now it is said that the product of silver in America is to be indefinitely increased.

The silver deposit in the San Francisco Mint during the first five months of the year was 209,104 minces. To give these mines fair play, science should discover some -quicker method of extracting the metal which could be practised on the spot. The silver can be moved, the ore cannot.
