HILL: GEOLOGY OF JAMAICA. 55 
The Richmond formation is exposed in all parishes of the east adjacent 
to the Blue Mountain Ridge, but in a greatly disturbed condition. It 
is best seen in the north coast parishes of Portland, especially the dis- 
tricts of St, George and Metcalfe in St. Mary Parish ; and in Hanover, 
in the bluffs and hills of the back coast country, cast, west, and south 
of Lucea, Excellent and typical exposures are seen between Richmond, 
district of Metcal fe, St. Mary Parish, and Annatto Bay, the beds occur- 
ring in many short open anticlinal and synclinal folds. At Richmond

a bluff in the banks of Flint River well shows the thin alternations of 
evenly bedded shales and sandstones overlying the conglomerates. (See

At Moral Cut, near Moral Station, thin flags of impure arenaceous 
limestone appear in alternation with the beds of shale (Fig. 19), and

of Wag Water the Richmond beds are vertical. Many other excellent 
€Xposures occur in this portion of the parish of St. Mary, constituting 
the western terminus of a belt of the formation which extends thence 
m a south of east direction through Portland Parish. It is impossible 
to obtain continuous sections of these beds, owing to minute folding
