The few days' delay we met with in getting out of Rio de Janeiro gave me an opportunity of Drawing a Plan or Sketch of great part of the Bay, but the Strict watch that was kept over us during our whole stay hinder'd me from taking so accurate a Survey as I wisht to have done, and all the Observations I could make was taken from on board the Ship. This Plan hath no pretensions to accuracy, yet it will give a very good idea of the place, differing not much from the truth in what is Essential.
The Bay of Rio de Janeiro, by some called a River--which its Name Signifies--but this I think is improper, it being nothing more than a Deep inlet of the Sea, into which no considerable fresh water River Emptys itself that I could hear of. Be this as it will, it is Capacious and Capable of Containing a vast Number of Shipping where they may ride in perfect Security. The Entrance is Situated West by North 18 Leagues from Cape Frio, and may be known by a remarkable Hill in the Form of a Sugar Loaf, at the West Entrance of the Bay; but as all the Coast is exceeding high, terminating at the top in Peaked Hills, it is much better known by the Islands laying before it, one of which (called Rodonda) is high and round in form of a Hay Stack, and lies South by West 2½ leagues from the Sugar Loaf or Entrance of the Bay. A little without the 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 ¾ 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 ½ 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 are Erected for the Defence of the Bay. The first you meet with coming in from Sea is a Battery of 22 Guns, seated in the Bottom of a sandy Bay, which is on the South side of the Sugar Loaf, and can be designed for no other use than to hinder an Enemy from landing in that valley, from whence I suppose they may March up to the Town or round by the West side of the Sugar Loaf to attack the Forts that are on that side of the Entrance into the Bay, the first of which is Seated under the foot of the Sugar Loaf on a low Isthmus which joyns the Peninsula or point of the Bay with the Land of the Sugar Loaf. It appears to be a square of Stone Work without a Ditch, with Bastions and furnished with Cannon. A little within this fort are 2 battrys of 5 or 6 Guns each. They are designed to play upon Shipping, but neither these battrys or the Fort are out of reach of a Ship's Cannon. Hard by these batterys stands Fort Logie. It is an irregular hexagon, built of Stone upon a Small Rock standing at the west Entrance of the Bay, and is surrounded on all Sides by the Sea. It is mounted with 14 or 15 guns, which are placed so as to play upon Shipping going in and out of the Harbour. There is only one way to go into it, which is by Steps Leading up to a Sally Port on the North-West side. Opposite this is the Fort of Santa Cruze, built upon a low rocky point that forms the East Entrance of the Bay. It hath the Appearance of a Regular Fortification of Stone Work built upon the Slope of the Rock, on which account there are in some places 2 Tier of Guns. It hath no Ditch but on the Land side, where it is cut out of the Rock; in every other part the Sea washes up to its Walls. It seems everywhere to be well Mounted with Cannon Except on the land side, where none are wanting, because they could be of no use, the land being so very high above it. Yet, after all, neither this Fort nor those on the opposite shore do not appear to be of any great Strength, even against Shipping, for which they are wholly design'd, being the key of the Bay. They lay low, and Ships may come so near as to have them entirely within the reach of their Guns; but it would require 5 or 6 Sail of the line to insure Success. Between 2 and 3 Miles within the Entrance of the Bay, on the West Side, is the Isle Borghleone, upon the east point of which is Erected a Battry of Stone, and Mounted with 17 pieces of Cannon. Besides this, on the highest part of the Island, is a Battry of 6 Guns mounted on an Open Platform. These battrys are designed to play upon Shipping in the Bay, and seems not ill designed for that purpose; yet they would be Obliged to Submit to the Attack of Shipping or that of a Land force, there being nothing to hinder the latter from Landing on the Island behind the Battrys. Opposite to this Island, on the low point on the east side of the Bay, is the Battry of St. Dominica of 7 Guns. A little without this Battry, on the East side of the Bay, is a small but high Island, close to the Shore, on the Top of which is the Church of Bonn Voyage, about half-way down the Cliff. Below the Church is a Battry of 3 Guns. Neither the one nor the other of these battry's are of much Consequence. They serve, indeed, to force Shipping coming into the Bay between 2 Fires, and hinder them from Anchoring on that side until they are silenced. The next fortification is that on the Ilha dos Cobras, the east point and North side of which consists of a Rampart Bastion and a Parrapet faced with Stones and mounted with Cannon, but no Ditch, which is not much wanting, as the works are built on the Edge of the rising Ground. The other side next the Town hath no other inclosure but a plain wall without any Guns. It is said that the works on this Island are in bad repair, on account of being so Extensive that they would take more men to Defend them than they could spare, and, placing no Dependancy on their Strength, let them go to decay. The ground on which the Monastry of Benedictines Stands Commands the Works on the Island. Over the South end of the City stands the Castle of St. Sebastian; it is Seated upon a Hill, and Commands the whole Town; and this is all I know of it, only that it is not counted a place of any great Strength. For the Defence of these Forts and the Town the King of Portugal Maintains 7 Regiments of Regular Troops. Those I saw were well cloathed and in good Condition; but this, as I was told, was not the Case with the whole. Besides these Troops are 3 Regiments of Militia, 2 of Horse and one of foot. These consist of the principal inhabitants of the place, who serve without pay, Muster and Exercise in turns nine Months in the year, on which account they rank with the Regular Troops.
The City of Rio de Janeiro is in the Latitude of 22 degrees 50 minutes South and Longitude 42 degrees 15 minutes West from Greenwich.* (* Modern determination, 22 degrees 54 minutes South, 43 degrees 10 minutes West.) According to Observations made at Sea it is Seated on a plain close to the Shore on the West side of the Bay, at the foot of Several high Mountains. It is neither ill designed nor ill built. The Houses are mostly stone, generally one and two Storys high, with Balconys to most of them. The Streets are of a Convenient breadth, and Cross each other at right Angles, and the whole City may be about 3 miles in Compass. It is Govern'd by a Governor appointed by the King. The present Governor is Don Anto Mendoyaz Fastada, who is no Friend to the English. It likewise is the Residence of the Vice-Roy and Captain General of the States of Brazil, who is as absolute as any Monarch on Earth, and the people to all appearance as much Slaves. This City and Adjacent parts about the Bay are said to contain 100,000 Souls; but not above a twentieth part are Whites. The rest are blacks, many of whom are free, and seem to live in tolerable Circumstances.
The city of Rio de Janeiro is supplied with Water from 2 Different parts of the Adjacent Mountains. That which comes from the Southward is Convey'd a Cross a Deep Valley by an Acquiduct, which Consists of a great Number of Arches placed in 2 Rows, one upon the other; from thence in pipes to a fountain which stands in the Middle of the Square before the Vice-Roy's Palace. At another part of the City is a Reservoir, to which the water is conveyed much in the same manner. From these 2 places, but mostly from
