Evening Republican, Volume 17, Number 70, Rensselaer, Jasper County, 22 March 1913 — Nails Protect Piling. [ARTICLE]

Nails Protect Piling.

Some of the piles in use in Amsterdam are 300 to 400 years old. That part which is not in the ground is often bored by a pile worm near the surface, but is preserved by driving in nails with very large heads, so as to give the pile an iron coating. Thia coating is then transformed by the water into a layer of rust, which protects the wood from the pllA worm. This process must be repeated every fifteen yean.
