SORTING AND STACKING. 271 



localit}^ according to the custom of the sawmills or floating 

 trade. The timber-trade prefers lengths of 10, 11, 12, 14, and 

 18 feet. The smallest class is usually used for water-pipes. 



iii. Remaining Species. 



Here according to the quantity of timber available, and the 

 demand, a separation into classes is advisable. Three classes for 

 each kind will suffice. Among broad-leaved trees, beech ranks next 

 to oak in importance, and most requires separate classification. 



Frequently logs and butts arc classed-together, and then six 

 to eight classes are required for oakwood and four to six for 

 conifers. 



B. Poles. 

 In this group poles used for building or other industrial 

 purposes come first, and then those used in agriculture. There 

 is great variety in difi"erent districts as regards their dimen- 

 sions : the following list only gives the more important classes, 

 most of which, and especially the larger sizes, may be sub-divided 

 into two, three, or even four sub-classes. 



1. Building- and scaffolding-poles, always coniferous, 30 — 50 



feet long and more, 100 pieces containing 200 — 300 

 cubic feet (6 — 8 cubic meters). 



2. Telegraph-posts, 25 — 30 feet long, 6 inches across at top. 



3. Ladder-wood, 20 — 40 feet long, 100 pieces containing 



175—200 cubic feet. 



4. Cart and agricultural implement poles, of both broad-leaved 



and coniferous wood, 100 pieces containing 100 — 175 

 cubic feet. 



5. Hop-poles, coniferous [except sweet chestnut — Tr.], 15 — 



30 feet long, 2i — 5 inches in diameter at 4 feet from the 

 base, generally sub-divided into four or five classes. 

 One hundred pieces contain 125, 80, 60, 35, 20 cubic 

 feet. 



6. Poles for fastening logs into rafts. 



7. Tree-props of different species. 



8. Tree-stakes of different species. 



9. Poles used for making hooping for casks. 



10. Crate-wood and hurdle-stakes.
