Graded I'ohimc Tables. 13 



of dimension stock was sawed for construction purposes about 

 the mill and yard. It amounted to about 20% of the total 

 cut of beech, and less than 5% of the birch and maple. All this 

 dimension stock was graded as No. 3 Common "Stickers," which 

 were taken as much as possible from beech, and to some extent 

 from the poorest maple and birch, were also graded as Xo. 3 

 Common. At one time, during the collecting of the data, there 

 was a special order for 3 inch stock, 12 feet long, which was 

 graded as Xo. 3 Common, but in reality w^as an intermediate 

 grade between No. 2 and Xo. 3 Common. This tended to in- 

 crease the amount of Xo. 3 at the expense of Xo. 2 in the 

 12 foot class, and its effect is plainly seen in the birch log rule. 

 In the case of the two highest grades in birch, namely firsts and 

 seconds, and firsts and seconds red, considerable two inch stock 

 was sawed, more especially in the red grade. However, the 

 amount in comparison to the total was small, less than 5%. In 

 the ma])le and beech there were sawed from time to time small 

 lots of i\", if" and 2|" stock but the combined amount of all 

 these thicknesses was less than 5% of the total. In all cases the 

 board.-- were sawed i" thicker than the standard dimension to 

 allow for shrinkage. The beech as a whole was of poor quality, 

 but the amount of Xo. 3 Common was undoubtedly increased 

 considerably by the large amount of dimension stock and stickers 

 sawed from this species. It will be noted that in the ten foot 

 class in the birch log rule, there is a greater proportion of the 

 poorer grades than in the longer lengths. This is particularly no- 

 ticeable in the Xo. i Common Red and in the No. 2 Common 

 grades. It is probably due in part to the fact that the longer 

 logs can be trimmed more advantageously and a limited percent- 

 age of short lengths is allowed in the upper grades ; but largely 

 to the fact that the greater proportion of the 10 foot logs were 

 top logs and hence knotty and of poorer quality. The mill crew, 

 e. g. sawyer, edgeman and trimmer man, were men of average 

 skill, all having had previous experience in hardwood mills of 

 other regions. 



Methods Used. 



The following statistics were obtained in the woods : D. B. H. 

 stump height, diameter inside and outside bark at stump and at 

 small end of each log, length of each log, total height of tree,
