y and with strong pressure they
will have a tendency to warp.
[Illustration: Fig. 49. The above illustration shows method
of loading kiln cars with veneer on its edges by the use of
the Tilting Platform.]
A kiln car of edge-stacked lumber, properly piled, is made up of
alternate solid sheets of lumber and vertical open-air spaces, so that
the hot air and vapors rise naturally and freely through the lumber,
drying both sides of the board evenly. The distribution of the heat
and moisture being even and uniform, the drying process is naturally
quickened, and there is no opportunity or tendency for the lumber to
warp.
In Figure 49 will be seen a method of loading kiln cars with veneer on
edge by the use of a tilting platform. On the right of the
illustration is seen a partially loaded kiln car tilted to an angle of
45 degrees, to facilitate the placing of the veneer on the car. At
the left is a completely loaded car ready to enter the dry kiln.
Gum, poplar, and pine veneers are satisfactorily dried in this manner
in from 8 to 24 hours.
In Figure 50 will be seen method of piling lumber on the flat,
"cross-wise" of the dry kiln when same has three tracks.

cross-wise of the Dry Kiln when same has Three Tracks.]
In Figure 51 will be seen another method of piling lumber on the flat,
"cross-wise" of the dry kiln when same has three tracks.
In Figure 52 will be seen method of piling lumber on the flat,
"end-wise" of the dry kiln when same has two tracks.
In Figure 53 will be seen another method of piling lumber on the flat,
"end-wise" of the dry kiln when same has two tracks.
In Figure 54 will be seen method of piling slack or tight barrel
staves "cross-wise" of the kiln when same has three tracks.
In Figure 55 will be seen another method of piling slack or tight
barrel staves "cross-wise" of the dry kiln when same has three tracks.
In Figure 56 will be seen method of piling small tub or pail staves
"cross-wise" of the dry kiln when same has two tracks.
In Figure 57 will be seen method of piling bundled staves "cross-wise"
of the dry kiln when same has two tracks.
