necessary to use the foi-eign article. It will be well, therefore, to 

 present what is claimed for Kanawha salt, by those who are most 

 familiar with its qualities Analyses of the salt and brines have 

 been made, and it is said to have less lime in its composition than 

 any other salt. It is a'so claimed that it is entirely free from 5?*^-

 objectionable for curing meats and that it contains some other in- 

 gredients, in greater quantity than any other salt, which add to its 

 curative or preservative qualities. Hence its popularity, wherever 

 tried, for such purposes. The properties alluded to are the chlorides

 reason of their deliquescent qualities, cause its absorption more 

 readily, and never allow it to cake on the surface of meats. 



The reputation of this salt among the pork packers of Cincinnati 

 is well known, and it needs no recommendation, at this day, from

 only as a matter of public interest, and to point to the want of 

 foresight in the Virginia Legislature, in not making provision for 

 the development of the immense mineral wealth of the Western 

 part of this State. The product of coal, salt, and iron, in a few 

 vears, by proper encouragement, would add very many millions of 

 dollars to the Tax List of the State, and furnish employment to 

 hundreds of thousands of laborers, whose willing hands would add 

 immensely to her resources.
