in one tensile test with this timber a breaking load of 17^ tons per square inch was 
recorded, a value only 3^ tons below that usually specified for wrought iron of ordinary 
quality. 
' The results given are fair averages only, the timber being obtained as logs, 
which were wholly cut up and tested." 
Mr. Julius' supplementary tests, 1907 (1908). 
Since the publication of (a), " and particularly of those portions referring to 
the strength of the timbers of the eastern States of the Commonwealth, various other 
data have been received, and notably a ' Report issued by the Government of New 
South Wales in 1905,' embodying the results of tests carried out since the publication 
of Professor Warren's test results in 1892. 
In this report the strength of certain of the timbeis indigenous to New South Wales and 
Queensland are set down at figures considerably below those previously quoted, and it is to be presumed 
therefore, that these latter results are more nearly repiesentative. 
Taking, however, the whole of the data published concerning these hardwoods, the comparatively 
small number of specimens tested, and the manner in which they were apparently selected and prepared 
(vide Prof. Warren's report), it precludes the acceptance of the resultant data as in any way conclusive. 
The Western Australian Government has therefore conducted a further series of tests upon the 
most important of the valuable hardwoods of Eastern Australia in a manner exactly similar to and 
with the same appliances as were used in the tests of the Western Australian timbers. 
Julius' results in turn come in for criticism at the hands of D. E. Hutchins 
(" Discussion on Australian Forestry," p. 224, 1916).
