11. Trough stone, three feet four inches .—Trigonias, 
the shell changed into spar, and Ammonites. (Similar to 
some parts of the last.) 
12. White bed, two feet eight inches .—Contains Am- 
monites. (Between 10 and 13.) 
13. Hard bed, three feet six inches.— Trigonias, the 
shell changed into spar and Ammonites. This bed is 
very like No. 11. (Rathe? less green sand than No. 10.) 
14. Fretting stone, two feet.— A soft stone and no 
shells. (A loose sandy Limestone with green sand.) 
15. Under bed, two feet. — Fragments of shells 
changed into spar. (More compact and finer grained 
than the last, and holding less green sand.) 
16. Under bed, two feet six inches. — Contains Trigo- 
nias, the cast of the outside of the shell a soft stone. 
(Like the last, except that it contains no spar.) 
The whole depth of Chicksgrove Quarry to the bottom 
of the stone is 6 1 feet 4 inches, measured by J ohn Moun- 
tague, foreman of the quarry. 
The scales of fish, erroneously supposed to have been 
found in this quarry, were from a tile-stone quarry on Lady- 
Down, in the parish of Tisbury, and about one mile 
N. W. from Chicksgrove Quarry. 
The above are the names by which the different beds 
are known by the people who work the quarry. 
Most of the stone contains calcareous spar, in the place 
of the fragments of shells dispersed through it, but No. 
14 and 16 are without it; the Spangle bed contains most. 
The rare stratum called by Geologists “ White Free- 
stone” and here called chalk, but from which it differs in 
its situation, occurs also at Brill, in Buckinghamshire^ 
and at Upway, in Dorsetshire
