EUCAL YPTUS. 



In water it swells greatly, thus in the Tasmanian vessels 

 built of this timber the seams are scarcely discernable 

 when these are taken on the ways for coppering. Uses: 

 Ship-building, wheelwright work, agricultural implements, 

 telegraph poles, piles, bridges. Its use for railroad sleepers 

 has been of late years supplanted by Eucalyptus rostrata 

 (checks too much for their use with ordinary seasoning, K). 

 L/aslett says that the old trees often decay about the heart- 

 wood like some of our old oaks. It is deemed to be use- 

 ful in the ways spoken of after the eighth or tenth year 

 of age. Heart wood and sap wood are generally rejected 

 in Tasmania as not durable. Color, generally pale yellow, 

 sometimes brown or grey. Height up to 330 feet. Sp. 

 gravity average by Balfour, 1.014 (63.19 Ibs per cubic foot).
