Several roadsare now melting the sleet on the rails by the use of a solution of calciumchloride. The solution is stored in a tank on the car and is led throughsmall pipes to the rail innnediately in front of the collecting . one gallon of solution is used per mile, making the about7V cents i)er mile. The effects of one treatment last for two or threehours during the continuance of a storm. Solutions of common salt have been used in the same manner,but it is claimed that the corroding action on the iron of the calciumcliioride is not as great as that of a salt solution. Fiar. -Ji.
