Since the communication to the Editor of the Western Journal was made, the following letter has been received from Judge Calhoun, formerly a member of Congress from Kentucky, now Judge of a district comprising eight counties, embracing Bon Harbor. The elevation of his position, and his residence in the county where Bon Harbor lies, are some evidence of the weight to which his statement is entitled.

The report of Professor Lawrence not embraced in the said communication, is also herewith annexed, by which will be seen the geological formation of the Bon Harbor region, and that in all probability there is here a body of salt water, as its existence will only be in accordance with the general example of coal fields above the falls of the Ohio at Kenhawa, Pittsburgh, and Zanesville, where wells have been sources of great profit, making very large fortunes   But if that has been the result there, and supplies for the Bon Harbor country come from them, how much more valuable ought salt wells at Bon Harbor to be ?

By Professor Lawrence's report it will be also seen that we have an abundant supply of fire clay.

For iron manufacture, no point can be better, as the pig passes by Bon Harbor to Pittsburg and Wheeling eight hundred miles above, and returns manufactured.

That when the Chagres and Panama railroad is finished, or one from the Missisippi to California, which must soon be commenced, the opening for supplies of manufactures from this region will be immense.
