a light that you will feel they are inherently of great interest, and 

 that very little is really known about them. Hard defined theories 

 are stated positively, which often do not agree with each other, or 

 with the most ordinary observations, and men of equal eminence 

 hold absolutely opposite ideas on some of the fundamental points 

 we have had under review. Our subject is one which must be 

 treated broadly, and, above all, not from merely local standpoints. 

 Observations at one place alone might give rise to the most 

 fallacious opinions, and the facts collected in the most widely 

 separated districts or countries must all be carefully weighed. 



I do not doubt but that much remains to be discovered on 

 this north-west coast, as to these Boulder Clay deposits, and the 

 most effectual way to acquire the greatest amount of knowledge as 

 to the formation, in the shortest time, and with the least expendi- 

 ture of unnecessary labour, would perhaps be a properly organized 

 examination by the members of this Association and of the Barrow 

 Field Club. The purpose of this paper would indeed be accom- 

 plished if it should be the means of producing joint action between 

 the two Societies, thus work would be economized and mutual 

 assistance rendered in these explorations, which probably might lead 

 to most valuable discoveries. If we work alone, we each may be 

 wasting our strength where the other has been before, whilst if we 

 both are aware of what each has decyphered of the dim records of 

 the icy past, the result could not fail to be a confirmation of the 

 old proverb that Union makes Strength.
