It would have made the bulletin more useful if for each region 

 height, volume, and growth per cent had been combined into one table, 

 somewhat as has been worked out for the Adirondacks in the follow- 

 ing table :

In Table 17 a column should have been provided giving the mean 

 annual increment (m. a. i.), based on cords, to show at a glance at 

 what age the culmination comes. We supply this as follows :

Table 18. showing normal yields for Norway spruce, raises the old 

 question whether our Site II is equivalent to the European Site II or 

 III (cf. recent issues of the Journal). The author apparently con-
