As this last pond will do for the party, I will return and bring them up, for there is a slight appearance of rain, and I wish to get them on as far as possible before the winter rain comes on. Returned to our last night's camp, where we arrived at sundown. Wind, south-east, with few clouds. Saturday, 7th June, Plain East of Blue Swamp. Returned to the Depot; found all well. Clouds all gone, but the wind blowing strong from the south-east. Sunday, 8th June, Daly Waters. Strong winds still from south-east, and sometimes from the south. Day very hot. Monday, 9th June, Daly Waters. Last night, a little after sundown, Mr. Waterhouse was seized with a violent pain in the stomach, which was followed by a severe sickness, and continued throughout the night; this morning he is a little better. I think it was caused by eating some boiled gum which had been obtained from the nut-tree Mr. Kekwick discovered last year. When boiled it very much resembles tapioca, and has much the same taste. I also ate some of it yesterday, which occasioned a severe pain in the stomach, but soon went off. Some of the others also felt a little affected by it, but none so bad as Mr. Waterhouse; on others it had no effect whatever, and they still continue to eat it. Mr. Waterhouse looks so ill that I think it desirable not to move the party to-day, and trust by to-morrow he will be quite well. Light wind from the south-east, with a few clouds. Tuesday, 10th June, Daly Waters. As Mr. Waterhouse is better, I shall move the party to-day. Started at half-past eight a.m., following my former tracks. At half-past four p.m. camped at the blue-grass swamp; twenty-six miles without water. The horses will require to be watched during the night. Wind, south-east. Day very hot. Latitude, 15 degrees 56 minutes 31 seconds. Wednesday, 11th June, Blue-Grass Swamp. Started at seven o'clock; course, 70 degrees east of north. At three miles crossed the ironstone rise, and at eleven miles changed to north, to cut the chain of ponds, which I have named Purdie Ponds, in honour of Dr. Purdie, of Edinburgh, M.D. At one mile and three quarters, on the last course, camped on the largest pond. The country that we have gone over, although there are a number of holes and cracks in it, is really of the best description, covered with grass up to the horses' bodies. We have passed several new trees and shrubs. The bean-tree is becoming more numerous here. At this season and in this latitude it sheds its leaves; the flower is in full bloom without them. The course of the ironstone rise seems to be north and south. Wind, south-east. Weather a little cooler, but clouds all gone. Latitude, 15 degrees 52 minutes 58 seconds.
