voyage^'. 
The Tamar arrived at Port Jackson on the 
28th of July, 1824 ; when every facility was ren- 
dered by the colonial government, to further the 
object in view. The expedition sailed thence in 
less than a month, with a detachment of the 3d 
regiment, and forty-five convicts, in addition to 
the party of Royal Marines that had been em- 
barked before the Tamar left England. The esta- 
blishment was placed under the command of Cap- 
tain Barlow, of the 3d regiment. A merchant 
ship, the Countess of Harcourt, was taken up to 
convey the stores and provisions, and the Lady 
Nelson, colonial brig, was also placed at the 
disposal of the commandant.

sage to the northward, and in less than three 
weeks cleared Torres’ Strait by the route you 
recommended to Captain Bremer, without en-

Mermaid and Bathurst, were not noticed; by 
reason of the greater altitude of the Tamar’s 
mast-head affording a much more extensive view
