A Blue Gum tree of full growth willaverage 7 feet diameter at the butt, 100 fest in length to thelowest branch, and from 200 to 250 feet in extreme height. Inthe sapling or pole stage Blue Gum grows rapidly, but when reach-ing maturity the growth is almost imperceptible, and it wouldprobably take from three to four hundred years to attain its fulldimensions. The rapidity of growth, however, is materially affectedby the natural surroundings, trees, for instance, under a shelter-ing hill, or in deep moist soil, being of much more rapid growththan those in the more ox))osed and rocky situations. The trunkis usually straight and cylindrical, with a thick bark, composed ofnumerous layers of a compact, short-grained, fibrous nature, andat certain periods the outer layer dries and peels off. sometimesin long strips, whilst in other cases the hark is shod in short curlv

The Blue Gum, together with other timber trees of Tasmania,is an evergreen. There is diversity of opinion regarding a periodwhen it is stated the sap is either rising or quiescent in our trees,more especially in regard to the Eucalypti, specimens of which may*be found in bloom at any period of the year. Some contend thatthe sap is always moving, such contention probably being occasionedby the varying local conditions in rainfall, humidity, and swampyand hilly country. One fact is undisputed, viz., that whilst at oneperiod of the year the bark may be stripped from a tree with com-parative ease, at another it can only with difficulty be removed,showing that the natural functions of the
