once destroyed the correlation of the Bored bed on the top of 
this Freestone with the one which exists on the top of the 
Upper Freestone in the Stroud area. 
Now an important link in our chain of evidence would be 
to show the separate existence of the Upper Freestone in the 
North Cotteswolds as distinct from the Notgrove Freestone, and 
to do this requires the introduction of our second series of 
strata, namely the sands, H. , These I wish to call the Harford 
Sands, because they seem to be best developed in the fine 
cutting between Harford and Over Harford, some two miles 
west of Bourton Station. It strikes me very forcibly that these 
sands have not improbably been confounded with the sands at 
the base of the Inferior Oolite—those sands which, in other 
parts of the Cotteswolds, are just above the Upper Lias and 
below the Cephalopoda bed. If so, we again have another 
reason for the alleged thinning out of the Inferior Oolite, as 
this stroke would deprive us of all the lower members of that 
formation. I shall further on have more to say in reference to 
the supposed identification of these sands in this manner, but 
at present it is most important that I should show the true 
position of the Harford Sands, because they are an easily 
recognised and very persistent horizon, and it is from their 
position, when once established, that we shall be able to work 
out the remainder of our deposits. 
It is most necessary to take as a starting point a bed or 
series of beds about the position of which there can be least 
argument, and I think that the Oolite Marl probably supplies 
us with such, and since it occurs in a very developed state 
at Notgrove Station, I append the following section of that 
cutting :—
