Passing the two buoys situated to the S.E. of the Bank Chico, and continuing to sail W.N.W. you will distinguish several ombus situated upon some hills. When you close in the two small woods of talas, upon the side of the river, then you close in to the Point of the Atalaya, and arrive to the small wood, or copse of talas, you will have passed the Bank Chico.
Leaving the copse of talas, the coast is very low, and presents small regions of sand, to a distance of about 6 miles; that which follows, and which is more raised, is the Forest of Santiago of the Ensenada: to the end of this Forest, there is three leagues of length; it is the Point, or Cape de Santiago of Ensenada of Barragan: arrived there, follow the same directions that have been given in the first course from Monte Video to Buenos Ayres.
Observations.
In the passage from Monte Video to the Southern Coast, the bottom is bad, as well as in the environs of Cape Indian.
From Cape Indian, as far as the first ombu, situated upon the land of the Magdalene, you must not anchor nearer than 6 or 7 miles from the shore, because there is a ridge of rocks, which extends itself to more than 5 miles, and on which anchors will not hold.
Variation of Depth of Water from Monte Video to Buenos Ayres, between the Banks Ortiz and Chico.
Leaving Monte Video, having the Cape to the S.W. you will find 2½ or 3 fathoms of water; at 9 miles, you will find 5 fathoms; at 18 miles from thence, you will not find more than 3½ fathoms; at 30 miles farther, you will have a quarter of a fathom less; proceed 33 miles farther, and the sounding lead will give you once more 3½ fathoms; in short you will find the same depth of 3½ fathoms, until you find yourself within six miles of the Southern Coast.
From Cape Indian, with the 3½ fathoms, steering to N.W. towards the Bank Ortiz, the sounding lead will give you from 4½ to 5 fathoms, according as the river flows or ebbs; when you do not find more than 3 fathoms, then you will be on the brink of the Bank Ortiz.
From the 3 fathoms from the brink of the Bank Ortiz, steer to the W. towards Buenos Ayres; your soundings will increase progressively from 5½ to 6 fathoms, according as the river is either low or high.
