76 Eeports of the Inspectors of 31ines. [Off. Doc. mine is situated, and the surveys of the face of the workings alono- such pillar shall be made in duplicate and must practically agree." In order to comply with this provision J. F. Snyder, chief miningengineer of the Delaware, Lackawanna and Western Railroad Company, J. H. Bowden, chief miningengineer of the Susquehanna Coal Company, W. J. Eichards, chief miningengineer of the Lehigh and Wilkesbarre Coal Company, and G. M. Williams, mine Inspector of this district, met and agreed that all the said pillars as far as related to their companies should be in accordance with the following terms and formulas Agreement In compliance with the requirements of section ten, article three of the act of June 2, 1891, entitled " An act to provide for the health and safety of persons employed in and about the anthracite coal mines of Pennsylvania, and for the protection and preservation of property connected therewith," it is hereby agreed between the engineers of the and of and the Inspector of mines of the Anthracite district of Pennsylvania, that the barrier pillars to be left, one-half {\) by each owner, between the workings on their adjoining properties, are to be, as nearly as practicable, of the thickness to be determined as follows : First. That after this date the width of barrier pillar between the workings of adjacent properties is to be five times the thickness of seam mined out fi-om floor to roof at the water drainage level ; and that at all points below such level its width shall be equal to the thickness mined out at that point multiplied by one per cent, of the depth below drainage level added to five times the said thickness mined out. Thus Thickness of workings X one per cent, of depth below drainage level + thickness of workings X 5 = width of barrier pillar. And as further illustrated by the attached table of pillars to be left between adjoining mines of different thicknesses of workings at difl'erent depths. Second. That the water drainage level shall be understood to mean the level at which Avater would drain ofi" from any abandoned workings, and that where the level is higher in one mine than in an adjoining one the higher level shall be taken, and where there is but one mine opened it shall determine its drainage level, and if the drainage level of a mine subsequently opened upon adjoining lands is higher, the additional thickness required shall be left by the owner of said mines. Third. That these thicknesses shall be subject to such modifications as may be deemed advisable under varying conditions of the strata and seams due to proximity of other seams, faulty nature of seam or strata or other conditions shown by the development of the workings. Fourth. That on notice of either party that any modifications of this agreement are desirable a meeting shall be forthwith held to decide the same. : :
