are then at a low point and because that season is usually the driest 

 in the swamps. Some choose the period following the spring high- 

 water stage. An important influencing factor is the danger of attack 

 by the pinhole borer or ambrosia beetle. For a discussion of this 

 subject, based upon extensive investigations conducted by specialists, 

 the reader is referred to Circular 82, "Pinhole Injury to Girdled 

 Cypress in the South Atlantic and Gulf States," and Circular 128, 

 "Insect Injuries to Forest Products/' issued by the Bureau of Ento-

WASTE IN LOGGING. 



Various forms of waste in logging are found in some regions. 

 Utilization is complete, however, in the most literal sense of the term, 

 among the Mississippi River operators; as a rule not a living cypress 

 tree is left, stumps are cut low, and top logs are taken. Where clean 

 cutting is practiced trees above 16 to 18 inches at the stump are taken 

 for lumber; from 8 to 14 inches for ties, piling, etc.; and practically 

 everything left by the axe is broken by the steam logger. Over the 

 Atlantic region the wood in the trees felled has in the past been utilized 

 much less thoroughly, and the smaller sized trees left standing. One 

 company in western Florida commendably adheres to a high diameter 

 limit in the selection of trees for felling, but wastefully cuts high 

 stumps and leaves large top logs. As thousands of deadhead logs, or 

 "sinkers," left 10 to 20 years ago, are now being taken out by machin- 

 ery, so in turn later cutters on the same areas will undoubtedly pick 

 up many large top logs and material left in high stumps. Although 

 present cutting may be for special sizes and grades of stock, it is 

 doubtful if it is wise or practical thus to leave large quantities of good 

 timber in the woods (PI. II). The high stumps often result from 

 sawyers working in the girdle line, which, of course, is chopped out by 

 the girdlers at as high a point as possible above the basal swell in order 

 to avoid unnecessary labor. 



Waste in logging cypress is generally attributed to the poor quality 

 of labor, but is usually due to carelessness in supervision and failure 

 to realize the true stumpage value of the material left. Operators 

 on the Atlantic coast, where freight rates to the larger markets are 

 considerably lower, should be able to apply to their own logging the 

 methods which have been worked out so successfully in Louisiana. 

 In many cuttings in the Atlantic coast region stumps are left 5 to 9 

 feet high in order to effect a slight saving in labor; while in Louisiana, 



a general practice, small trees are cut at 2 feet, and all others, up 

 to the largest sizes, at 3 feet. The amount of merchantable lumber 

 contained in the upper 2-foot seeiion of n, stump 4 feet in diameter 

 cut 5 feet in height, allowing '■','> per cent for defect and not including 

 the slab, is 90 board feet. At a stumpage rate of $8 per thousand
