"An inspection of the white lead paints on the fence indicated in every
instance a rough, chalked, and disintegrated surface that seemed to be
well worn, in some cases nearly to the wood. The strongly oxidizing air
of the seacoast is probably responsible for the early decay of this
pigment.
"It was observed that the combination type of paint showed better hiding
power than white lead, over the black crosses placed on the priming coat
of each panel, as a hiding power test.
