The ciirf I'l'd in tlie Rod-C'nift ((iiarry, is a shelly (lolitc. divided bi a bamr 

 oy.sU'r shells, 1.5 inehes frimi the Ion, and by a scennd bar of the same 

 shells 2i feet below the npper bar. 'i'he boltcmi heel in this -|uarvy is a « ell- 

 eompacted oolite, with very few shells, having a bed of roach 12 inches (hicK 

 at the top ; its characteristic distinctions are streaks of yellow occasionally. 

 It is the hardest bed in the island, but will nevertheless work and saw better 

 than the middle bed. owing to its beinK more homogeneous. Tlie roach is 

 throuc;hout the island oolitic, with a cement of carbonate of lime, shelly, and 

 full of cavities from casts of shells •, colour, whitish brown.

 considered the best bed for standing w ealher. 'I he green bed is varied in te.x- 

 lure, containing shells uner|ually cemented. The slant bed is very frialile. 

 The pinney beds are crys'alline. the bottom bed is the hardesi — tliey are most 

 in repute, are free in working, obtainable in large and sound blocks, and stand

 of the beds can be ■ aw n. Some are intersected » ilh small veins of calcareous 

 spar, others abound in shells, the cavities of which are filled with spar — but
