COAST NORTH OF PUZZUOLI. 



167 



Briclo-e^rnn out into tlie sea. (See Plate YII.)"^ This mole, 

 which is believed to he eighteen centuries old, consists of a 

 number of piers and arches, thirteen of which are now 

 standing, and two others appear to have been overthrown. 

 Mr. Babbao-e found, on the sixth pier, perforations of litho- 



domi four feet above the level of the sea; and, near the 

 termination of the mole on the last pier but one, marks of 

 the same, ten feet above the level of the sea, together with 

 great numbers of balani and flustra. The depth of the sea. 



at a very small distance from most of the piers, is from 30 



to 50 feet. 



Coast north of Puzzuoli. — If we then pass to the north of 

 Puzzuoli, and examine the coast between that town and 

 Monte Nuovo, we find a re- 

 petition of analogous phe- k^. 125. ' 

 nomena. The sloping sides of 

 Monte Barbaro slant down 

 within a short distance of the 

 coast, and terminate in an 

 inland cliff of moderate ele- 

 vation, to which the geolo- 

 gist perceives at once that 

 the sea must, at some for- 

 mer period, have extended. 

 Between this cliff and the sea is the low plain or terrace, 

 before alluded to, called La Starza (c, fig. 125), corresponding 

 to that before described on the south-east of the town ; and 

 as the sea encroaches rapidly, fresh sections of the strata may 

 readily be obtained, of which the annexed is an example.

b. Ancient cliff, now inland. 



c. Terrace (called La Starza) composed of recent 



submarine deposits.
