A PRIMER OF FORESTRY. 



rule, grows only in rich moist soil, and Beech only in 

 damp situations. Fire Cherry, on the other hand, is 

 most common on lands which have been devastated by 

 fire, and the Rock Oak is most often found on dry bar- 

 ren ridges. The Tupelo or 

 Black Gum and the Eed 

 Maple both grow best in 

 swamps, but it is a common 

 thing to find them also on 

 dry stony soils at a distance 

 from water. The knowledge 

 of such qualities as these is 

 of great importance in the 

 management of forest lands. 



REPRODUCTION BY 

 SPROUTS. 



Besides reproduction from 

 seed, which plays so large 

 a part in the struggle for 

 the ground, reproduction by 

 sprouts from old roots or 

 stumps is of great imi^or- 

 tance in forestry. (See fig. 

 38.) Trees differ very much 

 in their power of sprouting. In nearly all conifers ex- 

 cept the California coast Redwood, which has this ability 

 beyond almost every other tree, it is lacking altogether. 

 The Pitch or Jack Pine of the Eastern United States 

 has it also to some extent, but in most places the 

 sprouts usually die in early youth, and seldom make 

 merchantable trees. (See fig. 39 and PI. XXII.) In the 

 broadleaf kinds, on the other hand, it is a general and
