Tulip tree (Liriodendron Tulipifera) is also known under the common names 

 of "whitewood" and "yellow poplar". This wood is not native to Canada, 

 except in a small section of the southern part of Ontario. Tulip wood is prac- 

 tically all imported from the United States. It comes fourth in the list of 

 imported woods, and occupies the fourteenth rank amongst the woods used. 

 The average price paid for tulip, $42.48 per thousand feet board measure, is 

 higher than the price paid for ash. Machinery manufacturers paid $90 for this 

 material. 



Tulip is reported to be used by eight industries to the extent of 3 per cent 

 of the total. Over 45 per cent is used in car construction. 



It is claimed that tulip is the best American wood for holding its shape 

 after seasoning, and it seasons without checking or warping. It is easy to work 

 and takes paint well. Tulip wood combines softness, lightness, and toughness, 

 with durability. 



TABLE XV ELM 



*Less than one-tenth of 1 per cent. 



Elm is one of the most popular hardwoods of the province of Quebec, both 

 as an ornamental and as a lumber tree. It is used for almost every purpose for 

 which Canadian hardwood can be employed; but it has been particularly in 

 demand for cheese boxes and basket material. It grows to a very large size. 

 The species is mostly confined to the basin of the St. Lawrence. 



The greatest proportion of the elm used is white elm (Ulmus americana), 

 with a much smaller proportion of rock elm (Ulmus racemosa) and red, or slippery, 

 elm (Ulmus fulvd). The wood of elm is fairly heavy and hard when dry, and 

 fairly elastic and strong. It has an even and rather fine texture. The chief 

 faults of the elm are its non-durability and the difficulty of seasoning it. 



Rock elm is considered the most valuable wood of the three species. It is 

 harder, stronger, tougher, and more durable than the others. Rock elm is
