486 Geology of Canterbury and Westland. 



For the altitudes of the rivers crossing the Canterbury plains and 

 the Plains themselves, the reader is referred to the Tables on page 

 403—6. The Chief Surveyor of Canterbury, Mr. J. H. Baker, and 

 the District Engineer, Mr. Gr. P. Williams, have kindly furnished me 

 with a number of altitude observations, by which this list has gained 

 much in value. In all cases where altitudes of points, which I had 

 previously calculated from barometric observations, were amongst 

 them, I have substituted them for my own, as having been obtained by 

 more reliable methods. In my reports on " The altitude of the country 

 between Hokitika and Christchurch, by Arthur's and Browning's 

 Passes," and on " The head waters of the Biver Bakaia," I have 

 discussed at length the value of barometric observations when com- 

 pared with those obtained by the spirit-level, at the same time giving 

 the results of both methods in a tabular form. In this list only the 

 spirit-level altitudes along the "West Coast Boad are given, as obtained 

 by Mr. Edward Dobson, C.E., formerly Provincial Engineer of the 

 Canterbury Province, to whom I am indebted for them.
