FORESTRY AT PANAMA-PACIFIC EXPOSITION. 



The forestry and forest products exhibit at the Panama- 

 Pacific International Exposition will be shown in the Palace 

 of Agriculture, which, with the exception of the great Palace 

 of ]\Iachinery, is the largest exhibit palace of the exposition. 

 The Palace of Agriculture covers an area of 328,633 square 

 feet and was erected at a cost of $425,610. 



Group 134, under the officiol classification of exhibits, is 

 divided into four classes of forestry exhibits comprising forest 

 geography, maps, statistics and general literature, geograph- 

 ical distribution, botanical collections, seeds, bark, foliage, 

 flowers, fruit, bark and wood sections. The planting, equip- 

 ment and processes for tree collection, nursery practice, field 

 planting and field sowing, make up class 661. Management 

 and utilization, equipment and processes for protection from 

 fire, insects and disease, organization of protective forces, 

 ranger stations, trail and telephone systems, logging methods 

 and equipment, transportation of logs and systems of cutting, 

 comprise another. 



The indirect use of forests, such as watershed protection, 

 efiPects on climate and public health, prevention of erosion and 

 shifting sand, use of windbreaks for recreation or as a refuge 

 for game, is all considered in a separate class. 



Forest products are exemplified in three classes : Lumber, 

 equipment and processes used in cutting hmiber logs into 

 lumber, drying, dressing and grading of lumber and the rules 

 for grading; saw-mill and planing-mill products for the manu- 

 facture of lumber ; wagon-stock, cooperage, boxes, pickets, 

 shingles, and doors. Veneering and veneering-cutting ma-r 

 chinery will also be shown. Forest by-products — tanbark and 

 extracts, naval stores, oils and distillates, charcoal, cork, dye- 

 woods, medicinal and textile barks, kiln-dried wood, wood 

 fuels and wood wool, occupy another class. 



At least 2S per cent of the larch timber over large areas in 

 eastern Oregon has been killed or weakened by mistletoe, and the 

 forest service is taking steps to combat the pest. 



Success has followed forest planting on the sandhills of Neb- 

 raska. Jack pines planted there by the government forest ser- 

 vice ten years ago now have a height of over 15 feet and a dia- 

 meter of 4 inches. 



Increasing use of the national forests by local farmers and set- 

 tlers to supply their needs for timber is shown in the fact that 

 small timber sales on the forests numbered 8298 in 1914, against 

 6182 the previous year. 



Osage orange wood is a source of dye and can be used to sup- 

 plement the imported fustic wood, as a permanent yellow for 

 textiles.
