Supposed Discovery of a Petroleum Spring near Kilkeel,. - A few days ago the Kingdom of Mourne was agitated by the rumour that a petroleum spring had been discovered in the townland of Moneydarragh, near Kilkeel, on the farm of Mr. Henry McNeilly, who is over from America on a visit, has repeatedly declared that he had seen what his experience had led him to believe were indications of the presence of a petroleum spring.  Lately a quarry was opened, in which a quantity of water collected, and upon the surface of this a film of oily substance speedily formed.  This was skimmed off and about a pint of it has been bottled, and will be submitted to and analyst by Mr. J.Q. Henry, J.P. agent to the Earl of Kilmorey.  If the analyst's report should be favourable, it is expected that boring will be undertaken, with a view of ascertaining if petroleum in quantity is present in the strata underlying the Kingdom of Mourne.

DISCOVERY OF SILVER, IRON, AND LEAD ORE NEAR KILKEEL, COUNTY DOWN: In the townland of Leitrim, near Kilkeel, a number of miners have been engaged for some time past sinking a shaft. A few days ago they happened to come on a strata of iron ore; sinking further, they came on another of lead; and a little deeper they discovered silver ore. Should the quantity of the several metals prove so abundant as to enable the workmen to carry on operations, it will prove a new source of wealth to the kingdom of Mourne. It is understood that to Lord Newry’s keen research and persevering industry the present discovery is mainly attributable. His lordship must be congratulated on the discovery, which, it is hoped, may prove so extensive and remuniterative as to sufficiently reward that nobleman for his energetic and philanthropic exertions in behalf of his tenants on his. Mourne estate.
