by a marl seam. The only possible explanation I see is that in the 

 path of the prevailing wind, but a great way off, there lay a region of 

 great but intermittent volcanic activity, and that the marl is wind- 

 borne volcanic dust. Under these conditions there might easily be 

 produced the thin sharply defined marl beds deposited continuously 

 and in practically unvarying thickness over large areas at irregular 

 intervals, which we actually find. The large quantity of marl that 

 may be present in seams even in most typical ' White Chalk ' is a 

 point which seems not to have been realized by those who argue that 

 the residue after solution of even a considerable thickness of ' White 

 Chalk ' eotild not suffice to produce the ' Clay with Flints '.
