East Entrance of the Bay, and near the shore, lay 2 Islands near each
other: 3 leagues from the Eastward and 4 miles from the Shore are 2 low
Rocky Islands, which are the first you meet with in coming from the
Eastward or from Cape Frio.

To sail into Rio de Janeiro there is not the least Danger until you are
the length of the Fort of Santa Cruze, which stands on the point that
forms the East Entrance of the Bay or River; on the West Entrance is Fort
Lorio, built upon a Rock which lies close to the Main Land, the distance
from one Fort to the other is 3/4 of a mile East and West, but the
Channel for Shipping is not quite so broad by reason of Sunken Rocks
laying off each of the Forts; these rocks may not be properly placed in
the plan, being only laid down from the information of the Pilot. The
Narrowness of the Channell here causeth the Tides both Flood and Ebb to
run pretty strong, insomuch that you cannot Stem it without a fresh
breeze of Wind, nor is it safe Anchoring because the bottom is foul and
Rocky. By keeping in the Middle of the Channell you will not only avoid
being forced to come to an Anchor, but all other Dangers. Being got
within the entrance your Course up the Bay is North by West 1/2 West and
North-North-West something more than one League; this brings you the
length of the great Road, and North-West and West-North-West one league
more carrys you the length of the Ilha dos Cobras, which lies before the
City. Keep the North side of this Island close on board and Anchor above
it in 5 fathoms of water, where you see most Convenient before the
Monastery of Benedictines, which stands upon a hill at the North-West End
of the City. Small Ships and Vessels generally lay between the Town and
the Ilha dos Cobras, but in order to get there they must come round the
North side of the Island.

I shall now give the best description I can of the Different Forts that
