From introduction: In December, 1892, as the result of field work on the part of Dr. G. H. Williams in the northern and of the writer in the southern portion of South Mountain, there appeared a preliminary description of two of the rock types, in which their identification as ancient volcanics was announced. In this bulletin it is proposed to substantiate that identification with more detailed proof. It is further proposed to show that these ancient igneous rocks were, at the time of their consolidation, identical in character with their recent volcanic analogues, and that their present differences are due to subsequent changes, chief among which has been devitrification. It is also proposed to recognize these facts in the nomenclature.

Patent for a "simple, durable, compact, and reliable plant, house, or means operated by the force and energy of the wind without supervision or attention, and generating electricity and storing the same for use" (lines 10-14).

Patent for an improvement in whiffletrees, made out of steel. It includes a description and illustration.

Patent for "an improvement in cartridge-loaders adapted to load cartridge shells automatically, the machine being operated by suitable power. It consists in improved power mechanism and devices which may be arranged and combined with the loading mechanism of a machine cartridge-loader" (lines 38-45).

Introduction: By way of introduction a section will be described across the Devonian of the northeastern part of Monroe County, Pa., along the line of Brodhead Creek and the Delaware, Lackawanna and Western Railroad.

Patent for a baling press made up of a vertically movable core that moves up as it gets wrapped up in the internet, supporting drums, a feed apron that presses the material to the core, a pivoted swinging frame with a compression roller, a bale support, a mechanism that lifts the frame when the bale is finished, and a rack-and-pinion mechanism that raises the compression roller that moves up to let the bale get bigger, and a mechanism that rotates the rack-and-pinion.

From introduction: In his report on the Geology of Pennsylvania,' Professor Lesley summarizes his opinion upon the geology of the South Mountains and Formation No. 1. In this, Formation No. 1 is referred to the Upper Cambrian, and a detailed description is given of its occurrence along the South Mountains and across the State to the Delaware. The superjacent limestone, No. 2, is referred to the Ordovician.' Fuller reference will be made to Professor Lesley's descriptions in speaking of the rocks of York County.

From introduction: This report deals with the Middle and Upper Carboniferous System.
