at hand to extinguish a blaze as soon as it is discovered. Wood slow to take 

 fire is the best flask material, though choice is usually limited to kinds near 

 at hand or that are cheap. Redwood, when not too costly is preferred, because 

 it is generally conceded to be more fireproof than any other domestic wood. 

 Coating the inside of flasks with a fireproof chemical has been tried recently 

 as an experiment. Flask woods in order of their importance in Pennsylva- 

 nia are as follows: 



White pine. 

 Loblolly pine. 

 Hemlock. 

 Shortleaf pine. 

 Longleaf pine. 

 Yellow poplar. 

 Spruce. 

 Chestnut. 



White oak. 

 Pitch pine. 

 Norway pine. 

 Sugar maple. 

 White elm. 

 Red oak. 

 Beech. 



The Pennsylvania forests furnished only one-fourth of the total pattern 

 material used. This was probably due to the diminishing stand of white 

 pine timber in the State of the size demanded by the high grade lumber 

 pattern makers. Nearly seven-ninths of all that was used was shipped in from 

 West Virginia, the Great Lakes region, and western states.
