TRAVELS I NT 
a-hreaft - of fort Picolata ; where, being defirous of 
gaining yet farther intelligence, I landed ; but, to 
my disappointment, found the fort difmantled and 
deferted. This fortrefs is very ancient, and was built 
by the Spaniards. It is a fquare tower, thirty feet 
high, invefled with a high wall, without baftions, 
about bread high, pierced with loop holes and fur- 
rounded with a deep ditch. The upper ftory is 
open on each fide, with battlements, Supporting a 
cupola or roof: thefe battlements were formerly 
mounted with eight four pounders, two on each 
fide. 
The works are condru&ed with hewn flone, ce- 
mented with lime. The (lone was cut out of quar- 
ries on St. Anaftatius Ifland, oppofite St. Auguf- 
tine : it is of a pale reddifh brick colour, and a tef- 
taceous compofition, confiding of fmall fragments of 
fea-fhelis and fine fand. It is well adapted to the 
conflrucling of fortifications. It lies in horizontal 
mafles in the quarry, and conflitutes the foundation 
of that ifland. The caflle at St. Auguftine, and 
mod of the buildings of the town, are of this Hone. 
, Leaving Picolata, I continued to afcend the ri- 
ver. I obferved this day, during my progrefs up 
the river, incredible numbers of fmall flying infecls, 
of the genus termed by naturalifts Ephemera, con- 
tinually emerging from the mallow water near more, 
fome of them immediately taking their flight to 
the land, whilft myriads crept up the grafs and 
herbage, where remaining for a fhort time, as they 
acquired fufrkient ftrength, they took their flight 
alfo, following their kindred to the main land. 
This refurreclion from the deep, if I may fo ex- 
prefs it, commences early in the morning, and ceafes 
after the fun is up. At evening they are feen in 
clouds
