Sunday, 4th December, Primrose Springs. Examining the Neale for fresh-water springs. The water holes are abundant, but all more or less brackish; plenty of rushes on the banks, where fresh water can be had by scratching a little below the surface. I have not the least doubt but there will be plenty of fresh water on the surface for a long time after the creek comes down and sweeps all the soda and salt into the lake. It is the rapid evaporation that causes it to be so brackish, and I should think the consumption by stock would make a great improvement in it; there would not be so much of it exposed to the sun, and the evaporation would be much less. After considering the matter of having seen the northern boundary of Lake Torrens, I am inclined to think I have been in error. What I have taken for the lake may have been a large lagoon, which receives the waters of the Neale before going into the large lake: I must examine it again. After my surveys are completed, I shall move my party down the creek to where we found the good water, and from there see what it really is. I cannot bring my mind to think it is the northern boundary of the lake. Monday, 5th December, Primrose Springs. Moved the party down to the South Parry Springs. My eyes are still very bad. Tuesday, 6th December, South Parry Springs. Shortly after daybreak started for Louden Springs, taking different courses, in search of more springs, but can find none. Examined the George Creek, where the small run is to be laid off; found some good water by scratching in the creek, where there are plenty of rushes. A little before sundown we arrived at the springs. I did not observe before that the higher springs on the top of the hill are warm, but not nearly so hot as the others; the lower ones are cold. Some other party has been here; we have seen their fresh tracks and the place where they have camped; they seem to have been wandering about a good deal before they found these springs. Wednesday, 7th December, Louden Springs. Went to the top of Mount Stevenson, built a cone of stones, and obtained bearings to fix it. No appearance of any springs to the east of this, nor of the lake. Thursday, 8th December, Louden Springs. Surveying and building trigonometrical station on a light-coloured hill to the south of this. My eyes very bad; can scarcely see; can do nothing. Friday, 9th December, Louden Springs. Nearly blind; dreadful pain; can do nothing to-day; no sleep last night. Saturday, 10th December, Louden Springs. All yesterday the wind was hot and strong from west and north-west; heavy clouds from south and south-west. In the evening the wind changed to south. This morning still the same; heavy clouds from same direction. My eyes are a little better, so that I shall be able to do something. The sky being overcast I shall put up some of the corners of this run. Sunday, 11th December, Louden Springs. Still cloudy, but no rain.
