FORESTRY LESSONS OK HOME WOODLANDS. 15 



sawed in the district ? Wheat becomes of this lumber ? If there are 

 any wood product factories in the district, arrange for a trip to the 

 same and study the various processes from the rough wood to the 

 finished products. What timber in the district is most valuable? 

 Why ? An interesting study to make is the part forest products play 

 in the construction of machinery, transportation lines, airplanes, etc. 



Correlations. — Geography: Trace the timber products of the dis- 

 trict to their market. In a like manner locate the source of timber 

 products brought into the district and trace their probable route. 

 On a State map locate the timber areas and learn, if possible, the 

 important kinds of trees in each area. Locate the great lumber 

 regions of the United States. From what ports are forest products 

 of the United States exported? 



Arithmetic: Construct problems in which the prices of timber 

 products are used. Use, if possible, the value of the forest products, 

 the price of timber land, and prices of the miscellaneous forest 

 products. 



Language : Make a study of the forest products of the district and 

 write a report of your study. Another report of value will be that 

 on the forest products that are imported into the district. 



Lesson V. USING FARM TIMBER. 



Problem. — To discover the right uses of farm timber. 



Sources of information. — Farmers' Bulletins 516, 711, 715, 744, 

 1023, 1071, and 1117; Department Bulletins 718 and 753; Forestry 

 Bulletins 80 and 144; publications of State foresters and colleges of 

 agriculture. 



Illustrative material. — Again a field trip will furnish the best illus- 

 trative material for this lesson. Note the height of the stumps 

 where timber has been cut, the careless felling of trees causing the 

 injuring of young trees, the tops and large limbs left in the forest. 

 In the absence of a field trip, pictures may be shown illustrating the 

 points mentioned above. 



Topics for study. — The right using of timber on the farm should 

 begin at the time the tree is cut. Waste of good timber in the 

 woods is altogether too common nowadays, with high values on prac- 

 tically every kind of tree. 



High stumps mean usually that the best quality of the timber in 

 the tree is wasted. Often the value of the timber left in high stumps 

 is sufficient to pay for all the costs of logging. Saw logs can now 

 be taken profitably from the tops which had to be left only a few 

 years ago. Wherever possible the tops should be worked up into 

 crossties, mine props, or firewood. By careless felling of trees much 

 promising young timber is broken and destroyed.
