DUNDRY HILL. 
The Oolites of Dundry Hill, near Bristol, have always presented 
a problem of some difficulty to Cotteswold Geologists, who have 
found it no easy matter to apply their own local subdivisions to the 
80 or 40 feet of rags and freestones there developed, so as to bring 
the two sets of deposits into harmonious relations with one another. 
_ Mr. Lycett, though evidently entertaining some doubts respect- 
ing the true correlation of these beds, offers a solution of the question 
as follows :—He says, “at Dundry the quarries are capped with 
rag-stones, which seem to belong to the Spinosa Stage ;. this is under- 
laid by useful building freestones, and by sandy Oolite, in all nearly 
50 feet thick, which, probably, represent the Fimbria Stage. The 
Cynocephala Stage is here represented by only half-a-yard of ‘ Sands’ 
overlying the Upper Lias Clay.” We have here the Cotteswold 
serles apparently identified at Dundry, and [ visited the quarries 
with the expectation of being able to recognise the equivalents of 
the three stages as laid down by Mr. Lycett; but Iam bound to 
record as the result of my observations, my persuasion that the 
Dundry beds are a repetition and extension of those at Lympley 
Stoke and Charlcombe, having the Trigonia and Spinosa beds at the 
base, and resting on the ‘ Sands” as in the last-named localities, 
but with a greater extension upwards of the freestones, which like- 
wise assume at Dundry a purer grain, and more even and regular 
characters. 
The Freestones at Dundry occupy the eastern extremity of the 
hill, from which point, followed along their line of strike, they 
rapidly attenuate, so that within an area of less than a mile from 
their point of greatest extension, they cease to be any longer trace- 
able. The principal quarries are near the Church, and in what is 
known as the “ Upper Quarry ” the following beds are exposed :—

derived was the question, and an inspection of that and the adjoining 
excavations affording no satisfactory explanation, I awaited the re- 
turn of the quarrymen from their dinner to obtain information on 
the subject ; and learnt, in reply to my enquiries, that the rock in 
question lies at the bottom of all, and reposes upon a stratum of clay, 
which in its turn rests upon Sand. The clay was described as a 
water-bearing stratum, and in sinking a well for water in the 
quarry, the workmen had brought up the blocks of ‘ Trigonia and 
Spinosa grit” from the position indicated. The clay band would 
appear to be a merely local and accidental deposit; and I heard a
