split along the line of bedding. It is extensively quarried for 

 building and other purposes, being easily cut with the knife or 

 saw. Large blocks of it are turned into pillars, vases, balus- 

 trades, and other architectural ornaments. This stone is exten- 

 sively used for building in the islands ; and, for the same use, 

 is largely exported to many parts along the shores of the Medi- 

 terranean. It attains a thickness of from 40 to 50 feet. 



" The stone from which the finely-carved vases are cut, comes 

 from the lower part of this bed, and is obtained near Naxiar. 

 The rock in this locality dries whiter, is finer grained, and more 

 compact than in general." Spratt. 



" It is impossible to distinguish between the beds D, E, P, 

 in the above grouping, except in cliff-sections." Earl Dude.

No. 5. The hard cherty limestone, " is a yellowish- white 

 cream-coloured limestone, having sometimes semi-crystalline 

 strata alternating with an oolitic grit or sandstone, apparently 

 composed of minute fragments of shells and corals. It attains 

 a considerable thickness, since nearly 400 feet of it in perpen- 

 dicular depth is visible on the north-west coast of Gozo." 

 (Spratt.) "This bed forms a high and rocky coast-line on the 

 south end of Malta, and dipping to the north appears about the 

 water-line in the neighbourhood of Valetta and Sliema, forming 

 a barrier to the sea. Probably the softer superincumbent beds 

 have in course of time been worn away, till the appearance of 

 this rock arrested any further encroachment. A Scutella inva- 

 riably marks the junction of this bed with No. 4." (Earl Dude.) 

 The New Dock is built of this rock, and it is quarried in several 

 places for building purposes, and it is likewise burned for lime.
