Salt and Slush
“The practice of salting the tracks of city railroads, where­by they have been kept in a state of cold slush during winter, has called forth the wisdom of various city magis­trates and others in exposing the evils, or supposed evils, arising therefrom. The Common Council of Phila­delphia called in scientific experts to give testimony. Professor Rand, of the Franklin Institute, did not believe there was any increase of mortality among children from catarrhal diseases since the use of salt upon the rail­roads. The difference between salt and no salt is, that with salt you may have only have one day’s slush, where the slush would last a week without it.”
