The wooden parts of tools, such as the
stocks OF planes and hahdlasi OF chtsels,
are often made to have "a nicbs appear
ance byiFrench polishing, but this adds
nothing to their durability. A much bet
ter plan is to let them soak in linseedoil
for a week, and rub them with cloth for
few minutes every day for a week or
two. This produces a beautiful surface
and at the same time eXerts a sOlidlfying
and preservative action on the wood
The finding of large deposits of resin
imbedded in the earth on the island Of
Borueo has long been puzzle to natur-
alists. The subject has recently been in
vestigated by NJ, Posewiez, who found
that the resins are the product of num-
Der of trees belonging to the families
'conifera, dipterocarpg and'burscrace@."
The gums eXude on the limbs and form
large masses, which finally fall to the
earth of their own weight. The heavy
tropical rains soon imbed the humps in
the earth or wash them down into gull
lies, where they are buried by subsequent
rains.
A recent German invention, composed
Of pulverized iron and lnseed varnish, Is
intended for covering damp walls, outer
walls and, in short, any place or vessel
exposed to the action of the open air and
to the weather. Should the articles to be
painted be exposed to frequenj changes
of temperature, linseed-Oil Yarnish and
amber varnish are mixed with the paint
intended for the first two coats, without
the addition of any artificial drying me-
dunn. The first coat is applied rather
thin, the second little thicker, and the
last in rather fluid state.
To know whether water is hard or soft
dissolve little white soap in alcohol,
and add few drops of the water under
investigation. If the alcohol turns milky
it is hard; if either unaltered or simply
cloudy it is soft. To detect copper per-
centage, add a little filling dust of soft
iron to the water, leave it in for a few
minutes, and add few drops OF sal am
moniac. A blue colonization betTays the
presence of copper. Sulphur combina-
tions are detected by adding little water
to the mercury in the bottle, this is
closed and left to stand for few hours.
II the mercury assumes darker surface,
and upon shaking separates into gray
powder it is a sign that the water contains
sulphur combinations.
