In the event of occurrences of unexpected disasters, impediments, and
unavoidable accidents, arising from loss of provisions or of horses, or
of any injury to the health or strength of the party, rendering it
utterly impracticable for the expedition to proceed as high northward as
Gascoyne River, your discretion then supplying whatever you may be
unprovided for in your instructions, you will explore as far as it is
possible for you to do, on your return, the country north of the settled
districts of York and Toodyay; so that something of utility may be
accomplished, and the great object for which this expedition was prepared
may not be wholly frustrated.

I am further to add that His Excellency's best wishes accompany your
party, and that the success of the expedition, and the return of all
engaged in it in health and safety, will be hailed by him with very
lively satisfaction.

I have the honour to be, Sir,

Your obedient servant,

R.R. MADDEN,

Colonial Secretary.

To A.C. Gregory, Esquire, Perth.
