During the return journey to Nickol Bay, he ascended Mount Samson, and from the summit obtained an extensive view that embraced every prominent peak within seventy miles, including Mount Bruce to the north, and Mount Augustus to the south, the distance between these two elevations being 124 geographical miles.

They crossed the Hammersley Range on to the level plains of the Fortescue by means of a far easier pass than that used on the outward journey, and arrived at the Bay on the 19th of July.
On the 31st of July Gregory started on a new expedition to the east.

On the 9th of August he came to a river which apparently headed from the direction they desired to explore -- namely the south-east.

Crossing another river, which they named the Shaw, the explorers, still keeping east and south of east, found on the 27th of August, a river of some importance running through a large extent of good pastoral and agricultural land.

This river was named the De Grey, but as their present object was to push to the south-east, they left its promising banks and proceeded into a hilly country where they soon became involved in deep ravines.
