From the lay of the country to the northward of the Lyons River there does not appear to be any reason to suppose that a river of any magnitude falls into Exmouth Gulf, as there would be hardly room for it between the sources of the Alma and the rivers flowing to the north coast.
I cannot bring my report to a conclusion without recording my acknowledgments to Mr. James Roe for the able and effective assistance he has rendered me throughout the expedition, the barometrical observations and management of the provision department having been especially under his charge.
My best thanks are also due to Mr. W.D. Moore and Mr. C. Nairn, who on every occasion endeavoured to relieve me as much as possible from some of the many arduous duties that usually devolve on the leader of an exploring party. Chainer Fairburn and the native Dugel also gave general satisfaction in the performance of their respective duties.
I may add that to the ready cooperation and unanimity that prevailed throughout the party may in no small degree be ascribed the successful issue of the undertaking.
I have the honour to be, Sir, etc.,
F.T. GREGORY,
Assistant Surveyor.
To the Honourable the Surveyor-General, etc.
