about eighty miles (see map). Throughout the region there is a great 

 development of the Tertiary sedimentaries, and some of the localities have 

 been looked on as classical in the discussion of various points relating to 

 New Zealand stratigraphy. Notably is this true of the areas in proximity 

 to the Waipara River, the Weka Pass, and Amuri Bluff, probably no parts 

 of New Zealand furnishing better opportunities for studying the relation- 

 ship of beds with a Cretaceous fauna to those with a Tertiary fauna. Never- 

 theless there have been and now exist remarkable discrepancies of opinion 

 on the part of writers, and as we have had in the course of our search for

phosphatic rock ample opportunities to study the relationship of the beds 

 in different localities, and, as many miles of outcrops have been carefully 

 examined, especially those concerning which the discussion has been keenest, 

 we consider it appropriate to place on record the result of those observa- 

 tions, as far as they affect the question of the stratigraphy, in the hope 

 that they may aid in a definite opinion as to the points at issue being 

 arrived at. 



The most important question suggested by the investigation is the 

 matter of the conformity or unconformity of two limestones which are
