The passion for discovery soon took possession of the new arrivals, and the adventurous Governor placed himself in the front of this enterprise. To us who live in times when Australia has ceased to be an unknown land, their efforts in this direction may appear to have been small and the results insignificant, but it should not be forgotten that the horizon was at that time the limit of discovery, even in meagre outline, whilst an accurate survey had scarcely proceeded a couple of miles beyond the settlement. On the 2nd of May the Governor and party sailed off in the long-boat for the purpose of exploring Broken Bay, which had been seen and named by Captain Cook, but not entered. It proved to be the entrance to a large river, expanding to an immense width, and abounding in exquisite natural scenery. Having crossed the bar, three distinct divisions of Broken Bay were explored, and to the last of which they gave the name of Pitt Water, in honour of the far-famed English premier. Next year this success was followed up with the exploration of the river (the Hawkesbury) which here enters the sea. Large tracts of rich alluvial land were found on both sides. In a short time hence these fertile flats became the homes of an industrious agricultural population, who frequently saved Sydney from the horrors of famine. This voyage of discovery was continued as far as Richmond Hill (the Kurrajong), from which position the chasm in the mountains was distinctly seen, and the sentries which guard its entrance named the Carmarthen and Lansdown Hills.
