THE WOODS GROWN IN PENNSYLVANIA. 



Of the seventy-two woods which the manufacturers reported using, the en- 

 tire amount of only six was home grown. These were aspen, (or popple), 

 mountain laurel, sometimes called kalmia, black locust, sassafras, sumach 

 and willow. The forests in the State also furnished a part of the supply 

 of thirty-six other woods, making an aggregate of State-grown material used 

 equal to a little more than 28% of the total consumption. 



Instead of arranging the woods in the order of the quantity consumed, as 

 in Table 1, they are shown in Table 2 alphabetically according to their 

 generic names. This arrangement throws together consecutively the birches, 

 the cedars, the oaks, the maples, and the pines, and allows an easy compari- 

 son of amounts of each species used, and if desired, an aggregate of any of 

 them can be made readily. For a more convenient comparison of the home- 

 grown woods with those grown out of the State, not only the quantities of 

 these two classes are given for each species but also the per cent, which 

 each class represents.
