1905.-MacMalion, P. The Merchantable Timbers of Queensland " (Brisbane, 
JOS). Page 21, " Durability of Queensland sleepers "; p. 24, Strength of Queensland 
timbers.' Table 21 consists of transverse tests. The work contains many records 
(some illustrated by excellent photographs) of various physical tests, mostly undertaken 
by the Railway Department.

p. 140, including plates. 
This is a very important publication, and contains the results of original tests 
on Eucalyptus and other timbers. The Eucalypts are enumerated at pages 7 and 8. 
See also the corrections in the " Addenda " list. To some extent Queensland has a 
set of vernacular names of timbers of her own.

Notes are given in regard to twenty-one species. Particulars are given in regard 
to the Railway Department's tables (1916) of the strength and durability of some of 
them.

The tests for the transverse strengths in my experiments were conducted in every case with 
pieces 2 inches x 2 inches x 84 inches =336 cubic inches. Eac*h piece was placed upon supports exactly 
6 feet apart, and then water was placed gently and gradually into a scale suspended from the middle 
until the piece broke, note being taken of the deflection with 390 Ib. weight, and also at the crisis of 
breaking. 
After this a piece 2 feet 6 inches in length was taken, whenever it was found practicable, from one 
of the two pieces broken by the transverse strain, and tested for the tensile strain by means of a powerful 
hydraulic machine, the direct cohesion of the fibres being thus obtained with great exactness. Further, 
for the purpose of determining the proportions of size to length best adapted for supporting heavyweights, 
a great many cube blocks were prepared, of various sizes, as also a number of other pieces of different 
form and dimensions, which were then, by the aid of the same machine, subjected to gradually increasing 
vertical pressure in the direction of their fibres, until a force sufficient to crush them was obtained, 
A second edition of this work, edited and enlarged by the late Professor Marshall 
Ward, was published in 1893. Chapter XXIII is devoted to the " Timber-trees of 
Australia," and includes accounts, more or less full, of the timbers of Tuart 
(E. gomphocephala) , Jarrah (E. marginata), Karri (E. diver sicolor), Ironbark 
(E. siderophloia) (as E. resinifera), Blue Gum (E. globulus), Stringybark (E. obliqud). 
Most of the trees referred to being Western Australian, a note of it is given at 
this place.
