Water Boring at Harpers Ferry.

Mr. Tindrel, who has been engaged since last June, at Harper’s Ferry, in in boring for water, arrived in town, yesterday. He states that he has perforated the solid rock to the depth of 266 feet, and found good water at a far less depth, but that it would rise only to a certain height and no further. That he continued his operations, till the late great freshet in the Potomac, which on a sudden the muddy water of the river, backed into the hole he had bored in the rock, which induced him to believe that there was a communication between the hole aforesaid in the river. He was right in his conjectures, for when the freshet subsided, the water in the hole came down to its usual level, leaving the same limpid water as heretofore– And now Mr. Tindrel is on his way to N. York to procure copper tube, which, when fixed, and the interstices between its exterior and the rock being chinked up with a composition prepared for the purpose, he adds, there can be no doubt but that the water will rise to the surface of the earth, sufficient for all purposes. — Alexandria Her.
