nent share of the mixture. These grades of site are marked off 

 from each other by the factors of soil depth and soil moisture. 

 Beyond these limits are conditions of extremes toward which 

 the species rapidly fades in number and quality. 



The results are given in the table, and shown graphically in 

 the diagram. 



Site I: The "Bottomland" areas (not swampy). 



Site II : On this the type "Average Hardwoods" occurs. 



Site III: Verging on the rocky ridges and the "Oak Ridge" 

 type. 



In the best situations the largest advantage for height growth 

 comes during the first year. Afterwards, growth on sites I and 

 II is more nearly the same in amount. In the third year the 

 amount of height growth on site III diminishes much faster than 

 upon more favorable situations. The maximum quality I (the 

 largest set of results obtained from any one plot of quality I site) 

 shows a large increase over average conditions for the same 

 quality. 



Relation of Soundness of Parent Stumps to Height Grozvth of 

 Sprouts. — The removal of a crop of first or second generation 

 coppice wood of the ordinary type in Connecticut, usually reveals 

 a wide variation in the condition of soundness of parent stumps. 

 The problem here presents itself as to the subsequent rate of 

 height growth of sprouts from stumps of different degrees of 

 soundness. 



A study was made under the following conditions : ( 1 ) The
