Report of the Forest Commission. 141 



foresters were directed to confine their examinations to trees 

 which were 12 inches or more in diameter on the stump, 

 although the lumbermen were cutting the spruce there as low as 

 10 inches and occasionally smaller. With the exception of the 

 trees under 12 inches in diameter, the foresters examined 

 every spruce stump and top within the area selected until the 

 required number had been measured. 



In counting the rings of growth in these trees note was made 

 of the number at each inch of the radius with a view to deter- 

 mining the annual increase in diameter. 



In the following tabulation, Table IY, the first column con- 

 tains the specimen number, the next the diameter inside the bark 

 of the tree on the stump ; then follows the number of rings per 

 inch on the stump, counting from the heart outward, and along 

 the line of what might be termed the longest radius ; the last or 

 right-hand column on the left-hand page shows the total number 

 of rings, or age of the tree, as indicated at the height of the 

 stump. 



On the right-hand page the statistics for each tree are continued, 

 following the same specimen number, which, as before, is found 

 in the first column ; the next column shows the diameter of the 

 shaft at the top, or at the small end of the top log ; then come 

 the number of rings per inch at the top, counting outward from 

 the heart ; the next column shows the height of the stump ; the 

 next the combined length of the logs into which the trunk was 

 cut, each log being as a rule 13 feet 4 inches long ; the next 

 shows the length of the tree top or u leader " left by the lumber- 

 men, and the last column the total height of the tree as indicated 

 by the combined figures of the three preceding columns. 



The short dash or hyphen-mark, which appears occasionally in 

 connection with the last figure in a line, indicates that the radius 

 terminated in a fractional inch and, consequently, a smaller 

 number of rings.
