Since then he made another journey with the same object in view, but encountered extremely dry weather and underwent many hardships.

Hann was born in Wiltshire, in 1846, and came to Victoria with his parents at a very early age.

He spent most of his life squatting in North Queensland, where he held several station properties.
In the first year of the present century the Western Australian Government followed up Hann's explorations north of the King Leopold Range, by a larger and better-equipped party instructed to make a thorough examination of the region.

It was placed in charge of F.S.
Brockman, a Government surveyor, who had with him C.Crossland as second, F.House as naturalist, and Gibbs Maitland as geologist.
Brockman was born in Western Australia in 1857, was educated at Bishop's College, and after a spell in the bush on his father's properties, he joined a Government Survey camp, as cadet.

In 1879 he started as surveyor on his own account.
