About 50 years ago that well-known and enterpr.sing member of the English House of 

 (.'ommons, Mr. John Corbett, ])nrchased the large estate at Stoke Prior, upon which are the 

 celelirated Worcestershire Rock Salt Mines. 



Although these mines had been worked to some small extent for at least l,Ot)t) years, hut 

 little was known of the real character and excellence of the beds of salt, lying at such an immense 

 depth below the surface. However, through the energy of Mr. Corliett these mines have beeu 

 fully develoi>ed, and found to contain millions of tons of jaire glass-like chloride of sodium (pure 

 salt in white crystal formations), free from the reil oxide and many earthy imiiurities containeil in 

 the Cheshire Hock Salt. Hence no chemical or colouring matter of any soi't is reipiired or used 

 at this factory, any of which substaiu^es are more or less prejudicial to the successful cniing of 

 meat and provisions generally. The buildings and plant of this factory, covering an area of 

 30 acres, have been erected at a cost of not less than £530,001), no expense being spared in 

 machinery and improvements for the j)roilnction of the tinest Stoved and best Curing Salt, which 

 is now deservedly classed as the purest the world produces. 



These mines were worked by the Romans, and as the ]iay of a Roman soldier was in salt 

 it is said that the word salai-y was in this way derived.
