pine, western yellow pine, redwood, Douglas fir, western red cedar, Sitka 

 spruce, and sugar pine. The region of the southern states contributed large 

 amounts, equivalent to 34 per cent, of all, including more particularly the 

 several species of southern yellow pine lumber and cypress. The Ohio valley, 

 the Lake states, and New England, sent in varying amounts, which explains 

 the comparatively small quantity of home-grown woods used by the planing 

 mills. It must be remembered, however, a large number of these species are 

 not common lumber trees in Pennsylvania. 



Only 28 per cent, of the total amount of lumber used was produced in the 

 State. But of the species consumed that are plentifully cut in Pennsylvania, 

 the reports show the demand for a high per cent, of home-grown woods. For 

 instance, over 45 per cent, of the white pine, 67 per cent, of the hemlock, one- 

 third of the chestnut, 80 per cent, of the sugar maple and beech, 60 per cent, 

 of the birch, and half of the basswood reported by the planing mills, were 

 cut from State timber, indicating the importance the forests bear to the de- 

 velopment of the State. The planing mill Industry is not only the most promi- 

 nent wood consuming industry in the State but it appeals more widely to the 

 interest of every class of citizens than any other. In order that the supply of 

 lumber the State contributes for building material may be maintained and 

 probably increased in the future, it is necessary to protect and improve the 

 forests as far as possible. With this in view the Commonwealth has put into 

 effect and has in operation a progressive forest policy which if given popular 

 support will help to solve the problem of future lumber supply.
