210 APPENDIX 



VI. Lay off an acre or half-acre plot. Make a list of all 

 trees on the plot and find the percentage of the different 

 species by dividing the number of trees of a certain kind by 

 the total number of trees on the tract. 



VII. Make a list of trees found growing only in the open, 

 intolerant trees, and a list of those found growing under the 

 shade of other trees, tolerant trees. 



VIII. Note for different species of trees the time when 

 the buds begin to swell in the spring, the time when the leaves 

 are fully developed, the time of blossoming, the time when 

 the leaves fall, and the time when the seed is ripe. 



IX. Lay off a sample plot in the woodlot and have students 

 write a description of the plot, kinds and percentages of trees, 

 size and height of trees, condition of the trees, whether injured 

 by fungus diseases or insects, the undergrowth, the reproduc- 

 tion, forest floors and the humus. 



X. Have students mark with chalk or otherwise the trees 

 that should be removed to increase the growth of the trees 

 left or to improve the character of the woodlot. 



XI. Have students study the market conditions, the prod- 

 ucts that are in demand and the prices of each delivered. 

 Information can be secured from portable sawmill men, from 

 lumber dealers, and from those that utilize the products or 

 purchase them. 



XII. Estimate all the products in a woodlot, or those in 

 a certain portion, and figure what profit can be made by har- 

 vesting and selling the products. 



XIII. Study the reproduction of trees in the woodlot to 

 find under what conditions of soil and light the seeds germi- 

 nate and the seedlings develop the best. 



XIV. Visit a portable sawmill and scale logs with different 

 log rules before they are sawed, and measure the amount of 

 lumber that is actually sawed out of the logs, and compare the 

 results. Determine the loss due to defects in logs. 



XV. Visit a woodlot that has been heavily grazed and
