SAWING AND EXPORT.
659
A good quality in the timber is characterized by its being sound
and (as far as possible) free from knots, and by the wood being
close-grained. This quality depends upon the shape which the trunk of the
tree has had (a »pillar-shaped» tree gives the best timber), and upon the
fact that it be cut before its growing capacity has essentially ceased.
Many things may deteriorate the quality of the wood, e. g. »discoloured
wood», which arises from fermentation of the sap; cracks or warping
(»shakes»), which are caused by uneven seasoning, or else depend upon
the tree being too old; and »wane», caused in sawing. — Sorting is a very
important work, and the men who perform it, the brackers (klampare),
receive higher wages than others.
Transporting to the lumber-yard.
In shipping sawn timber to English-speåkhig countries, a
distinction, respecting quality, is made between mixed (a denomination
properly signifying seconds, with a mixture of firsts), 3rds, 4ths, 5ths,
6ths (also called inferior 5ths), and »wrack» (wrack-refuse). For other
markets, French sorting is used, i. e. prima, secunda, tertia, quarta,
and quinta quality. (Thus thirds in the English classification
correspond to secunda in the French). Whitewood is most frequently shipped
nnsorted.
