The observations behind tlie above tables were recorded with a view to 

 general results. In oidnr that they nii>i,ht thus serve, the observations 

 had to be freed from the danjjei-s attending selection. It was desired to 

 find the actual production of the country rather than to determine any 

 possible ideal. Therefore, when such notes were taken it was the usual 

 practice to take all trees come to. In starting in, however, there was some 

 variation in this practice, and throughout the work on tlu> Kennebec I 

 did allow myself some leeway. That is, very unthrifty trees were avoid- 

 ed, and an occasional very heavy crowned one as well. The results so 

 understood, however, are thought to be representative. They cannot be 

 much if any above the actual average of the country. They are doubtless 

 less than by careful handling could be obtained. 



When exploring on the Androscoggin I put myself under a stricter 

 rule. AVhen notes were taken only very seldom was a tree of the size 

 desired passed by, in those few cases where a tree was evidently diseased 

 or very badly crippled by suppression. Tlie fact probably accounts for 

 the difference in scale between the figures from the Kennebec and those 

 from the Androscoggin. The accompanying table of growth for spruce 

 on cut-over lauds on the Audioscoggiu is based on observations on about 

 300 ttees. The stands most often represented are mixed spruce and hard 

 wood. 



One other thing may account for the difterence spoken of in part. The 

 Androscoggin lauds traversed were on the average some 400 feet higher 

 than those explored on the Kennebec. If the difterence is due to this 

 fact, a striking relation is here found. That is, the region of the heaviest 

 stands and the largest and finest trees has yet a slower growth in diam- 

 eter, volume and per cent. I can only state this suggestion and hope for 

 further light. 



The subject of the representative character of these figures was dis- 

 cussed on page 124.
