Shortly after the construction of the Port Darwin telegraph, Mr. Giles made a persevering attempt to lead a small party from Chambers's Pillar to the sources of the Murchison River. The expenses were provided partly by himself and partly by Baron Von Mueller, of Melbourne. The party consisted of Messrs. Giles, Carmichael, and A. Robinson, with fifteen horses and one dog. The start was made about the middle of August, 1872. For the early part of the journey the River Finke was followed, but it led them into a rugged, mountainous country, in which travelling was difficult. The scenery was often charming, as one glen after another was explored. Palm-Tree Glen, in particular, called forth unceasing admiration on account of the multitude of wild flowers which were "born to blush unseen and waste their sweetness on the desert air." "I collected to-day," says Mr. Giles, "and during the other days since we have been in this glen, a number of most beautiful flowers, which grow in profusion in this otherwise desolate glen. I am literally surrounded by fair flowers of many a changing hue. Why Nature should scatter such floral gems in such a sterile region is difficult to understand; but such a variety of lovely flowers of every colour and perfume I have never met with previously. They alone would have induced me to name this the Glen of Flowers, but having found in it also so many of the stately palm-trees, I have called it the Glen of Palms." During a further advance among the outlying spurs of the M'Donnell Ranges, the Finke was left, or lost, and laborious search had often to be made for water. The mountains were high, but no creek was found with a longer course than twelve miles. The peaks often assumed strange and fantastic shapes, as the explorers have indicated by such names as Mount Peculiar, Haast's Bluff, &c. The following quotation from the journal shows how they were straitened at this time through want of water. After finding a little in the hollow of a rock, just sufficient to save life, Mr. Giles says:--"It was necessary to try to discover more water if possible, so, after breakfast, I walked away, but, after travelling up gullies and gorges, hills and valleys, I had to return quite unsuccessful, and I can only conclude that this water was permitted by a kind Providence to remain here in this lovely spot for my especial benefit.... I have, in gratitude, called it Mount Udor, as being the only one in this region where a drop of that requisite element was to be obtained. And when I left the udor had departed also." This incident occurred at the twenty-first camp from Chambers's Pillar. From this point a persevering, but unsuccessful, effort was made to strike out west in the direction of a chain named Ehrenberg's Mountain. Want of water again forced the party back on Mount Udor. A more southerly route led to the important discovery of a great saltwater lake, which was called Amadeus, after the then King of Spain, son of Victor Emanuel.
