About a thousand people areemployed within itswalls, and itsvaults contain in normal times about one hundred million dollars' worth of gold and silver. The weighingoffice contains machines which weigh sov ereigns at the rate of thirty-three per minute, throwing those' of full weight into one compartment and thelight ones into another. Half a million dollars' worth of gold is thus tested daily.
