Threshing machines, including grain threshers and clover huUers, are 

 the most important commodities of this industry, and in this particular line 

 of manufacture Pennsylvania leads all other states. There are many interior 

 parts of these machines that require woods of different qualities. The 

 general tendency to substitute metal for wood has not proved practical and 

 consequently a majority of these parts like grain registers, dust conveyors, 

 and screen frames are still made largely of wood.- Likely for the same rea- 

 son, frames and siding or exterior panels of threshers call for wood and 

 white pine and yellow poplar are the principal panel woods because these 

 woods are light, easily worked, take paint readily, and are not given to 

 twist and check. 



Straw-carriers, closely allied to threshers, are another product Important 

 in this industry in Pennsylvania. Woods similar to those for threshers 

 are demanded; white oak, yellow poplar, and sugar maple in the order named 

 being most frequently called for. 



Corn shellers and land rollers demand a considerable amount of lumber 

 each year. Beech for framing, shortleaf pine, and yellow poplar for panels 

 play an important part in making the former, and sugar maple and oak 

 for the latter. The rollers of land rollers were formerly made of wood. " A 

 cross-section from a sycamore or yellow poplar log was usually selected and 

 the rollers were usually made on the farm or at nearby blacksmith shops. 

 Today these implements are in universal use and have been found indis- 

 pensable, as a labor saver. The factories sometime ago began making them 

 and now use metal almost entirely, but a small amount of wood is still in 

 use and hard maple meets the demand in the State. The bottoms of the roller 

 platforms are of shortleaf pine but any strong wood will answer for this 

 purpose. The roller blocks or bearing frames are of hard maple. The hay 

 baler manufacturers also use sugar maple ahead of other woods; but oak, 

 both white and red, is indispensable for certain parts.
