Messrs. A.C. and F.T. Gregory, who were attached to the department of the
Surveyor-General, applied for three months' leave of absence for the
purpose; but it was eventually arranged that the expedition should be
under the auspices of the Government, which provided four horses, and
voted 5 pounds for the purchase of equipment, the remainder being
supplied at private expense.

The party consisted of A.C. Gregory, F.T. Gregory, and H.C. Gregory,
provided with four horses and seven weeks' provisions, the equipment
being reduced to the least possible weight. The starting point was Mr.
T.N. Yule's station, in the Toodyay district, sixty miles north-east from
Perth.

EXPLORATION TO EAST OF SWAN RIVER, 1846.

DIARY.

7th August, 1846.

Leaving Mr. Yule's farm at Boyeen Spring, passed Captain Scully's station
at Bolgart Spring at 10.15 a.m.; thence steered north 70 degrees east
over sandy downs, thinly timbered with eucalyptus; at 12.50 p.m. crossed
a small watercourse trending in the direction of our course till 2 p.m.,
when it turned south; at 3.50 p.m. halted for the night on a small stream
flowing to the south-west.

Latitude by observation 31 degrees 12 minutes 10 seconds; longitude 116
degrees 50 minutes.

8th August.

At 7.5 a.m. commenced a course 70 degrees; at 8.0 crossed a granite hill
with some grass, after which the country was scrubby till 9.30, when we
entered a grassy flat timbered with casuarina; at 10.25 the country was
more open, but scrubby; at 12.45 p.m. observed a small lake bearing 10
degrees; steered on that course, and reached it at 2.10 p.m.; halted till
3.15, and then resumed our former course through a swampy country, and at
4.50 camped on the bank of another small shallow lake.

Latitude by observation 31 degrees 4 minutes 24 seconds; longitude 117
degrees 4 minutes.

9th August.

At 7.35 a.m. steered on a course of 95 degrees through a scrubby country
with small wooded valleys; at noon observed several large shallow lakes
five to ten miles to the north-east; at 3 p.m. altered the course to 45
degrees, and at 3.30 to north; at 4 p.m. reached a large open flat
covered with salicornia and other salt plants, and with shallow lakes of
salt water. At the edge of the flat found a native well with good water
and a patch of grass around it, and bivouacked.

Latitude by observation 31 degrees 2 minutes 22 seconds; longitude 117
