Some Words Woodsmen Use 



ABSCISSION The natural separation of 

 parts of a plant (such as flowers, bark, 

 fruit, leaves, or branches) by the break- 

 down of the absciss layer, which is a layer 

 of cells across the base of a branch or 

 embedded in the bark through which the 

 leaf or branch or other part breaks off. 



ACCESS ROAD A road built into isolated 

 stands of commercial timber so they can be 

 reached by loggers, fire fighters, and others. 



ACID WOOD Wood cut for use in plants 

 that manufacture charcoal, acetic acid, and 

 methanol by destructive distillation. It is 

 sometimes called distillation wood or chemi- 

 cal wood. 



ARBORICULTURE The science and art of 

 growing trees, especially as ornamental or 

 shade trees. Distinguished from silviculture 

 or forestry (the science and art of growing 

 trees as a forest or for lumber) and from 

 tree horticulture or pomology (growing 

 trees for fruit, nuts, etc.). 



ASSOCIATION As used in botany: An 

 assemblage of plants, usually over a wide 

 area, that has one or more dominant species 

 from which it derives a definite aspect. 



BACKFIRE A fire intentionally set along 

 the inner edge of a control line located 

 ahead of an advancing fire, for the purpose 

 of facilitating control by a widening of the 

 control line and the removal of intervening 

 combustible materials. 



BALL-HOOTER A slang term loggers use 

 for a man who rolls or slides logs down a 

 hillside. 



BARBER CHAIR In loggers' slang, a stump 

 on which is left standing a slab that splin- 

 tered off the tree as it fell. Generally it indi- 

 cates careless felling. 



BLAZE A mark made on the trunk of a 

 standing tree by painting or chipping off a 

 spot of bark with an ax. It is used to indi- 

 cate a trail, boundary, location for a road, 

 trees to be cut, and so on. 



BOLE The stem or trunk of a tree, 

 usually the lower, usable or merchantable 

 portion of the tree trunk. 



BOOM ( 1 ) Logs or timbers fastened to- 

 gether end to end and used to hold floating 

 logs. The term includes also the logs en- 

 closed. There are many varieties depending 

 on construction and use, such as bag, barge, 

 bracket, catch, fender, fin, glancing, hold- 

 ing, limber, pocket, receiving, round, rud- 

 der, shear, sorting, storage. (2) Projecting 

 arm of a log-loading machine, which sup- 

 ports the log during loading. May be either 

 of the swinging or the rigid type. 



BROADLEAF A tree with two cotyledons, 

 or seed leaves; it usually is deciduous that 

 is, it sheds all its leaves annually. The 

 broadleaved trees, such as maple and oak, 

 have relatively broad, flat leaves, as con- 

 trasted with the conifers, such as pine, 

 which have narrow leaves, or needles. 



BUCK To saw felled trees into logs or 

 bolts; to bring or carry, as to "buck" water. 



BURL A hard, woody growth on a tree 

 trunk or on roots, more or less rounded in 

 form. It is usually the result of entwined 

 growth of a cluster of buds. In lumber, a 

 burl produces a distorted and unusual (but 

 often attractive) grain. 



BURNS Areas in which fires have in- 

 jured the forest. 



CAMBIUM A soft layer, strip, or cylin- 

 der of living cells, one row thick, between 

 the living bark and living wood of a tree. 

 During the growing season its cells divide 

 continuously, giving origin to the wood tis- 

 sues and the bark tissues. 



CAMP INSPECTOR To loggers, a man 

 who drifts from camp to camp, trying out 

 the food and living accommodations but
