In regard to thecomparative costs of railway lubricationthe data available have not been suffi-ciently segragated to show what is actuallychargea1)le to packing. On this point taken the standardizing the grades andmethods of manufacture, and the appli-cation of lubricants, and real progressbegan to be made. The lubricants werepurified and specially adapted to the high-est service, and in the matter of packingit was soon discovered that neither woolnor cotton possesses all of the desirable. the properties desirable in a packing thanany other, the long coarse wool and themethod of spinning giving a naturalresilience. The demand for these threadsis great, and the price high, and thereis not sufficient available to fill the require-ments of the railroads. Others are of opinion that an all cot-ton packing gives best results, but tliefact is that cotton has more often been railroad men ha\e not reached an agree-ment.
