ME. S. S. BUCKMAN - ON THE 



[Nov. 1903, 



It seems desirable to state exactly the nature of the evidence 

 obtained. The stones in the gateway were typical * Upper Lias ' 

 nodules; the gateway itself was on 'Upper Lias' Clay, Anyone 

 who knows how a farmer will take the least possible trouble to 

 obtain materials to harden a field-gateway, especially one where there 

 is no cart- traffic of importance, can judge that these nodules were 

 picked up close to the gate, and that they are, in every probability, 

 within a few feet of their vertical position. Then the hill is com- 

 pletely isolated : the stones were about on the 800-foot contour- 

 line, which is a steep climb of some 650 feet up from the vale. 



As regards the finds in the gravel-pit, the material of tnis pit is 

 the scree or talus of the hillside. It is angular gravel, not worn, 

 and it has not been, in a strict sense, transported. It is material 

 that has slid down from the hill, and is comparable to the -talus 

 so often seen at the foot of a quarry or escarpment, or of a railway- 

 cutting. Its value as evidence for what is in the hill above is the 

 same as that of tumbled blocks found in such places as quarries, or 

 cuttings ; but it does not indicate the exact position, nor does it give 

 the actual thickness. But the relative sequence of fossiliferous 

 blocks may be known by the sequence which has been ascertained 

 elsewhere. 



To show what the finds at Bred on Hill indicate, the following 

 Table is given, stating the sequence of hemerse, and indicating the 

 various deposits made, in the Cotteswolds, during those times.

1 The term ' Aalenian,' as now used, replaces in part the term ' Upper 

 Toarcian' employed in my paper on 'The Cotteswold, &c. Sands ' Q.uart. Journ. 

 Geol. Soc. vol. xlv (1889) pp. 473, etc. ; and the term ' Toarcian ' is almost equal 

 to the term ' Lower Toarcian ' in that paper (see below, p. 457)-
