A tree of Eucalyptus amygdalina in the recesses of Dandenong, 

 was measured by Mr. D. Boyle, and found to have attained a 

 height of 420 feet. Mr. G-. W. Robinson supposes this.Eucalypt 

 towards the sources of the Yarra to attain a height of 500 feet. 

 He found the circumference of a tree growing in the back ranges 

 of Berwick to be 81 feet, at the distance of 4 feet from the 

 ground. A Eucalyptus on the Black Spur was measured by Mr. 

 G. Klein, and its height found to be 480 feet, consequently exceed- 

 ing by 40 feet twice the height of the towers of Notre Dame Ca- 

 thedral in this city, and overtopping the tallest of the celebrated 

 Sequoia Wellingtonia's, or Big Trees of California, by 155 feet ; 

 as, according to J. D. Whitney,. the State Geologist, the Sequoia 

 known by the name of " Keystone State," in the Calaveras grove, 

 stands at the head of the Big Trees, with an elevation of 325 feet, 



' and this, he adds, is the tallest tree yet measured on this conti- 

 nent, so far as our information goes. 



If the size of these Eucalypts is astonishing, not less remark- 

 able is the quantity of timber supported by the soil in the places 

 where they grow. In the State forest at Dandenong (Victoria), 

 it was found by actual measurement that an acre of ground con- 

 tained twenty large trees of an apparent average height of about 

 350 feet, and thirty-eight saplings of an apparent average height 



. of fifty feet; the land being occupied besides by a dense under- 

 growth. Again, in one of the densest parts of the Mount Mace- 

 don State forest, an acre of messmate (Eucalyptus fissilis, Ferd. 

 Mueller) forest was found to contain forty-two large standing 

 trees and twelve saplings. Many of the largest of these trees 

 were from six to seven feet in diameter, four feet from the 

 ground, and from 200 to 220 feet high. These measurements 

 were taken by Messrs. Couchman and R. Brough Smyth ; the 

 latter gentleman states that in the Mount Juliet Ranges, he 

 found trees of far greater height and standing much closer to- 

 gether than in the Macedon Ranges. The Eucalypts are of very 

 rapid growth, and it is more than probable that the extraordinary 

 dimensions which some of these trees have attained is not so 

 much the result of a very great age, but is rather due to extreme 

 rapidity of growth. This marvellous quickness of growth, com- 

 bined with a perfect fitness to resist drought, has rendered many 

 of these trees famed abroad. Baron Von Mueller says : " In 

 Australian vegetation we probably possess the means of obliter- 

 ating the rainless zones of the globe, to spread at last woods over
