Although however, they agree to differ amongst themselves, there can be no doubt of the loyalty of the group, as a whole, to their parent nation.

I shall go no further into this matter, as, although English enough, it is foreign to my subject.

I shall treat more especially of the colony or colonies within whose boundaries my travels led me, and shall begin with South Australia, where my first expedition was conducted.
South Australia includes a vast extent of country called the Northern Territory, which must become in time a separate colony, as it extends from the 26th parallel of latitude, embracing the whole country northwards to the Indian Ocean at the 11th parallel.

South Australia possesses one advantage over the other colonies, from the geographical fact of her oblong territory extending, so to speak, exactly in the middle right across the continent from the Southern to the Indian Ocean.

The dimensions of the colony are in extreme length over 1800 miles, by a breadth of nearly 700, and almost through the centre of this vast region the South Australian Transcontinental Telegraph line runs from Adelaide, via Port Augusta, to Port Darwin.
At the time I undertook my first expedition in 1872, this extensive work had just been completed, and it may be said to divide the continent into halves, which, for the purpose I then had in view, might be termed the explored and the unexplored halves.
