weights per car allowed for different woodlot products, the approxi- 

 mate weight of I, GOO board feet of green logs of different species 

 measuring i8 inches in diameter, the average amount of woodlot prod- 

 ucts that may be loaded on a freight car, and the rate per carload for 

 different distances. 



The author also discusses a simple method of estimating trees in 

 board feet by determining the diameters and length of logs in the tree 

 and finding the board feet from a log table. He also discusses how and 

 where to sell the timber in the woodlot and states the advisability of 

 using a written contract.

Farm Woodlot Timber: Its Uses and Principal Markets. By George 

 N. Lamb, Forest Examiner, U. S. Forest Service. Extension Bulletin 

 51, Department of Agriculture Extension. Purdue University, Indiana. 



According to the Tenth Census, the 215,485 farms in Indiana pro- 

 duced $5,603,000 in woodlot products. This amounts to $26 per farm. 

 There are 3,370,791 acres in woodlands, an average of 15.6 acres per 

 farm. The average annual income per acre of woodland from woodlot 

 products is therefore $1.67. 



Between 50 and 60 species are commercially important in Indiana, 

 although all are not marketed separately as lumber or other forest 

 products. In the northern half of the State beech, sugar maple, and 

 white oak make up the major part of the upland stand, together with 

 basswood, yellow poplar, hickory, and ash. Through heavy cutting, the 

 percentage of white oak has been heavily reduced. The species typical 

 of the bottomlands are elm, soft maple, black walnut, hickory, hack- 

 berry, sycamore, pin oak, and burr oak. Between these two types large 

 areas are found where any combination of these species may be seen. 



In the southern half of the State the typical upland areas support a 

 white-black oak type with maple, beech, basswood, yellow poplar, chest- 

 nut, and chestnut oak in mixture. Pine is found in the rougher lands. 

 Red gum and black gum mixed with elm are the chief species in the 

 lowlands. 



The author lists 17 species of chief commercial importance from the 

 standpoint of the woodlot owner, and describes for each the possible 

 markets for dift'erent kinds of logs and other material and the distance 

 which it is practical to ship different products. He notes the chief in- 

 dustries demanding woodlot timber and their requirements as to kinds 

 and sizes, such as saw timber, veneer wood, fuel wood, railroad ties,
