Canterbury and Westland. 229 



"Wills, an important branch, joins it on the same side, draining the 

 western slopes of the high snow-covered peaks at the head of the 

 Hunter river, whilst two miles lower down, the Bourke, a large stream 

 coming from the west, augments the volume of the river considerably. 

 For five miles more, the Haast continues its northerly course, when it 

 enters a broad valley running at a right angle to it, and having a 

 general east and west direction. Here it is joined by the waters of 

 the Landsborough, a broad glacier river, the main sources of which 

 come from Mount "Ward and some other peaks of the central chain. 

 Its course is of a length of about 15 miles, with a westerly direction. * 

 Near the junction of these two confluents, another important branch, 

 principally draining the southern flanks of the Hooker and Gray 

 ranges, and which I have named the Clarke, unites with the Haast. 

 It lias a nearly south-west course, and near its head waters, Docherty's 

 Pass is situated. After this junction, the valley of the Haast trends 

 for about eight miles to the west-north-west, when, after having 

 received a considerable affluent from the north, it turns again at right 

 angles to the south-west, keeping this course for about eight miles, 

 when for the remaining 13 miles, it again resumes its former west- 

 north-west course. 



Okuetj and Waiatoto. 



Between the Haast and Arawata, the Okuru and "Waiatoto rivers 

 fall into the sea, of which the former has its sources on the 

 western slopes of Mounts Dana, Kinross, and Bowen ; and the latter 

 on those of Mounts Castor and Pollux, all prominent peaks in the 

 central chain. 



The Abawata. 



Of the remaining rivers, the Arawata, entering the sea in Jackson's 



Bay, is worth mentioning. I have only seen it at its mouth, but Dr. 



Hector, who has explored its upper course, describes it as a true 



glacier river. Its main source issues from the Haast glacier, descend- 



* Mr. Gerh. Mueller, who has lately explored the Landsborough, kindly informs me that it« 

 course, as laid down in this map, is not quite correct, the main source, instead of coming from 

 Mount Cotta, being situated on the western flanks of Mount Ward. The main valley, instead of 

 running in a west-south-west direction, has consequently a nearly east and west course. At the 

 same time, I wish to observe that, by a mistake of the draughtsman, the junction of the Lands- 

 borough and Clarke rivers has been placed about three miles above their real junction.
