The curious and well-known by-productof zinc, chloride or salts of zinc, whichformerly went to waste, is now beinglargely used as a wood preservative byrailroads, bridge builders, dock builders,and for the protection of shingles, clap-boards and any other wood that is ex-posed to moisture or influences produc-tive of decay; the salts of zinc, in solu-tion, by means of hydraulic pressure areforced into the pores of the wood, whichis then soaked in a solution of tannin andglue. An important fact in this connec-tion is that the ties and piling now usedon the Santa Fe & Southern Pacific, andsome other Western roads, are treated inthis manner, the companies named usingannually the large amount of three millionto four million pounds each.
