"As before stated, the committee believes that a serious mistake was
made on the test fence in painting out the leads and other formulas on
the various woods without any special attention to reduction to suit the
nature of the wood, thus accounting largely for the difference of the
wearing of the paints on the different woods.
"The reduction of the white leads especially was to be criticised in
these tests, in many cases too much oil and not sufficient turpentine
being present to cause penetration.
"The application of paint to cedar was satisfactory in most all cases,
and this wood showed much better results than the other woods upon the
fences. The exudation of resinous pitch on the hard pine was extremely
serious, in some cases coming through the paint in large streaks,
causing bad results.
