shipping of a great deal of stock which would not be adapted to the

Of sawed veneer the yield is about half what it would be in 
straight sliced, because the saw kerf is about the thickness of the 
veneer sheet. Thus, a 20-inch log with an equivalent volume to the 
linear foot of 524 square feet of veneer one-twentieth inch thick, 
after it is squared, and 10 per cent is deducted for waste in the sheets 
and in the " dog board," yields 126 square feet of veneer to the linear 
foot. This makes only about 8 square feet of veneer to the board 
foot of log. 
Kinds of veneer. — Walnut veneer is generally termed plain, striped, 
or figured, although there are no hard and fast lines of distinction 
separating the three kinds. 
Plain veneer is without stripe or figure. It is produced mainly 
by the rotary method, but some of it is made by straight slicing from 
the log in the tangential direction. (PI. VI, fig. 1.) The veneer 
produced by the straight rotary process is generally plain. In forest- 
growth timber in which the annual rings are not very distinct the 
straight rotary method gives a coarse effect to the veneer, and in 
open-growth timber the more distinct growth rings give a still 
coarser effect, producing a very "wild" design. (PI. VI, fig. 2.) 
Plain veneer is also produced by the stay-log rotary process. If 
cutting is from the sapwood side, the effect is somewhat similar to 
that produced by the rotary process, but some striped effect is ob- 
tained, especially toward the center of the log. If cutting is from 
the heartwood side, the striped effect is obtained at first, the veneer 
becoming plain in the middle, and entirely plain before the flitch 
is sliced down to the "dog board." Plain veneer is also produced 
by straight slicing near the outside of the log. 
In striped veneer the lines caused by the growth rings are fairly 
straight. This effect is produced both by straight slicing and the 
rotary stay-log method. The veneer straight sliced from near the 
center of the log has the most distinctly striped effect, especially if 
the veneer is from an open-growth tree in which dark and light lines 
alternate. These stripes are sometimes so marked that the veneer 
resembles that made from Circassian walnut. In straight slicing 
the stripes become broader as the sheets are cut at a greater distance 
from the center and the striped effect is not so pronounced. 
Striped veneer is produced by the stay-log method when the cut- 
ting is from the heartwood side. Near the center of the log a quar- 
tered effect is produced. (PL VII, fig. 1.) At a short distance from, 
the center striped veneer is obtained along either edge of the strip. 
Slicing from the outside of the log gives a striped effect to the 
middle part of the sheets cut near the center of the log.
