EUCALYPTUS DIVEESICOLOR. 



These proportions will be subject to some variation, according to the age of the trees. These 

 measurements were made under the author's direction by Mr. L. Hummel. 



E. diversicolor seems as hardy as E. globulus, though it may prove less so than E. amyg- 

 dalina, E. Gunnii, E. pauciflora, E. viminalis and even E. obliqua, E. Sieberiana and E. gonio- 

 calyx, among the larger kinds of timber-trees of this genus. Dr. Aberg finds, that on the entrance 

 of the La Plata-River E. diversicolor turns out one of the fastest in growth, and if the species was 

 rightly determined E. corymbosa carried there besides E. globulus the palm, E. obliqua and 

 E. siderophloia coming next in this respect. On the rich alluvial soil there grew also compara- 

 tively fast : E. Gunnii, E. Leucoxylon, E. hfemastoma, E. largiflorens, E. longifolia, E.goniocalyx, 

 E. cornuta, E. rostrata, E. tereticornis and E. maculata, but the latter with E. marginata and 

 E. calophylla suffered there from frost. Many grew in that region from two to even five inches 

 daily during the most favorable time of the season ! 



When gradually through the progress of settlement the harbors between King George's Sound 

 and Cape Leeuwin will be opened up for trade, Karri-timber will become extensively available for 

 export also.
