liad been preceded by a time of less high water. A few miles east of Baku, a flat 
hill-top (B, fig. 17) was sparsely strewn with water-worn cobbles at a height of 430 
feet ; and here we found a well-formed pothole, about 3 feet in diameter, and of 
somewhat less depth, with a c 
round stone hing in it. South-

end of the monoclinal ridge be-

bles, pebbles, and broken shells lay at a height of about 460 feet; but it may be 
that this is simply a remnant of a Pliocene deposit. 
The most interesting records of the modern high-level Caspian near Baku were 
found in three cobble spits at about 600 feet altitude above the present water level. 
As no accounts of the Baku district that I hav'e read make mention of shore records

at SO great an altitude, these spits will be described in some detail. The first one 
was found at S, fig. 15, on the top of the horseshoe ridge of the late Tertiary Aralo-

wells. The spit was somewhat east of the apex of the ridge cur\e. The anticline
