EXCHANGES. 



''The Victorian Naturalist, "" Nos. 10, 11, and 12. *'A Trip 

 to North and North- West from Broken Hill," by Dr. W. Mac- 

 Gillivray, will be found of great interest. 



''The Measuring of Tall Trees," by Mr. A. D. Hardy. In 

 this article the writer deals with the subject of the tallest trees 

 in Australia, which have been measured by competent observer 

 and duly recorded. His investigations lead him to put tlie 

 highest tree on record as 375 feet. This tree, growing at 

 Thorpdale, in Gippsland, was measured by a licensed surveyor, 

 G. Cornthwaite. The second highest, at Mount Dandenong, 

 was measured by a civil engineer, Mr. G. W. Robertson, who 

 measured the tree to its 9-inch diameter top as 342, the esti- 

 mated total height being 360 ft. Mr. Hardy graphically de- 

 scribes the difficulties met with in securing accurate heights, 

 and ends with a plea for the preservation of these noble trees, 

 probably the highest in the world.
