Limestone and Cement.

THE "Lower Helderberg," and "Water Lime" formations, both crop out within the city limits. The Limestone of the former series occurs near to the surface, in the North- eastern side of the city, along the foot of a hill; West of Wills Creek it forms (with the Oriskany sandstone) the hill upon which the Western half of the city is built. There are several points where this stone is easy of access, and where it can be quarried to advantage, the quarries on the Western side of the city being easily accessable, both by rail and water. The stone is of fair quality, average samples analysing less than 3 per cent, of Silica. The "Water Lime," or "Cement" rock, crops out in the Northern part of the city, on the Western bank of the Wills Creek. It has been quarried at this point for over thirty years, by the Cumberland Hydraulic Cement Manufacturing Company, whose Mills, etc., are located on the banks of the creek near the quarries.

The Hydraulic Cement manufactured here, and sold under the name of "Lynn Cement" and "Cumberland Cement," has been favorably known to contractors and builders for over thirty years, and is highly commended by such Engineers as Benjamin H. Latrobe, C. P. Manning, and Maj. Henry Brewerton, This Cement is noted for the energy of its action, and will bear a greater admixture of sand than any other natural Cement now in use.

We append below a table showing the weight in pounds sustained by Cement Mortars, made into prisms two inches square, by eight inches long, and broken on supports four inches apart, by pressure in the middle. The Cements were kept in sea water after the first twenty-four hours, and were 320 days old when subjected to the test. The result of this severe test was in every way favorable to the "Cumberland Cement." As will be seen from the table, it is second only to the celebrated Portland (artificial) Cement of English manufacture, and superior to all other natural Cements.
