30 THE THEORY AND PRACTICE OF WORKING PLANS 



b. Depth: Very shallow less than 6 inches 



Shallow 6 to 12 inches 



Moderate 12 to 24 



Deep 24 to 36 



Very deep over 36 



c. Color and consistency (light, binding, stiff, etc.) 



d. Soil moisture: 



Wet: when water drips from a piece held in the hand 

 without pressing. 



Moist: when water drips from a piece pressed in the 

 hand. 



Fresh : when no water drips from a piece pressed in the 

 hand, though it is unmistakably present. 



Dry: when there is little or no trace of water. 



Very dry: when the soil is parched. Such soils are 

 usually caked and very hard, sand being an excep- 

 tion. 



e. Agricultural value. 



8. Forest floor (the deposit of vegetable matter on the ground 



in a forest). 



a. Litter (the upper, only slightly decomposed portion of the 



forest floor). Deep, moderate, scant, etc. 



b. Humus (the portion in which decomposition is well 



advanced). Give the depth in inches. 



9. Ground cover (all small plants growing in a forest, except 



young trees; such as ferns, mosses, grasses and weeds). 

 Specify as herbaceous, woody, grass, ferns, moss, etc., 

 and state amount. 



10. Underbrush (all large woody plants, such as laurel, striped 



maple, witch-hazel and devil's club, which grow in a 

 forest but do not make trees). 



Note. — Undergrowth includes ground cover, underbrush, seedlings, shoots, 

 and small saplings. 



11. Reproduction (trees less than 10 feet high, from sprouts 



or from self-sown seeds). State whether the repro-
