ANNIVERSARY ADDRESS. 9 
complete. Since that time a number of additional contributions 
have been given to the world. In addition to his scientific writ- 
ings and the literary work connected with his ecclesiastical func- 
tions, Mr. Clarke published, before emigrating to Australia, two 
or three volumes of poems; and from time to time in this 
country he indulged his taste in verses, although he did not 
again collect them so as to put forth a book. 
Considering the great number of separate papers which issued 
from Mr, Clarke’s busy brain and pen, it is somewhat remarkable 
that he did not, except to a limited extent, seek to collect and 
condense his vast stores of information into convenient volumes 
for scientific libraries. It is probable that want of means in 
addition to want of leisure was the chief cause of this apparent 
neglect ; but whatever the cause the fact is to be regretted, for the 
difficulty of referring to papers scattered over many periodicals 
and many years is such that practically they drop into oblivion, 
and it is difficult now to form a just conception of Mr. Clarke's 
enormous labours. On two subjects, however, Mr. Clarke col- 
lected his observations into books—the first, published in 1860, 
entitled “Researches in the Southern Gold-fields of New South 
Wales,” and the second, entitled “ Remarks on the Sedimentary 
Formations of New South Wales,” a fourth edition of which was 
completed a fortnight before his death. 
The portion of Mr. Clarke’s geological labours most closely 
_ connected with the prosperity and advancement of the Colony is 
doubtless that relating to the discovery of gold and indication of 
gold-fields. Although other names may be associated with his— 
for example, Count Strzelecki and Sir Roderick Murchison on the 
Scientific side, and Mr. Hargraves on the practical side—yet, after 
looking carefully through the available evidence scattered over a 
variety of publications, I have no hesitation in saying that Mr. 
Clarke deserves the chief credit as the discoverer of gold in Aus- 
tralia. As far back as February, 1841, he found gold near 
Hartley, apparently about the same place where Strzelecki had 
_ found an auriferous sulphide of iron in 1839, although of this
