SALT WATER IN FIRES.
The recent disastrous fire in San Francisco, when $1,000,000 worth of property was destroyed, shows the lack of a proper system of fire protection. The water pressure was altogether too low. With a view to remedying this evil, which is recognized by the authorities, the Olympic Salt Water Company of San Francisco, has for some months past been laying its mains, and intends to bid for the patronage of the city. The company proposes to offer the city free of cost all the salt water needed for sprinkling purposes in the section where their mainsare laid and their hydrants set. Fighting fire with salt water is not an experiment, but has been successfully used in England for years. It has been proved beyond question that salt water is best adapted for fire purposes, and there are several reasons why this is so. First, the density of the water does not allow it to evaporate so readily, thus allowing it a longer period to get in its destroying power. Again, salt water weighs sixty-four pounds to the cubic foot, as against sixty-two pounds for fresh water. The difference of course is found in the salt. It is claimed that one service of salt water is equal to three in fresh. Returns from seventeen English cities where salt water is used for sprinkling purposes show that the streets have gradually become macadamized. The mortality has also decreased from twenty to thirty per cent. The Olympic Company has a reservoir with an elevation of 320 feet above the city. The reservoir is on Point Lobos avenue, near Josephine street, and has a capacity of 4,500,000 gallons.
