3d. From 3 fathoms on the Ortiz Bank, steer S. E. by the compass until you make Point Indio. In this track you will deepen your water to 5 or 5 fathoms, crossing the middle channel, according to the state of the river. Passing the middle of the channel the water diminishes gradually according as you near the land.

4th.

When

When you think you are about 7, 8, or 9 miles from the land, which will be in 34 or 3 fathoms of water, steer E. S. E. and coast it along.

5th. When Point Indio bears S. W. by the compass, steer N. E. by E. until you see Monte Video, which may be seen about 30 or 33 miles distant from the top of a common-sized vessel. Keeping your course N. E. by E. you will continue in 3 fathoms of water until you find yourself 6 or 7 leagues from Monte Video.

6th. When you find 5 fathoms of water you will be 9 or 10 miles from the harbour of Monte Video.

From the said 5 fathoms to the harbour it will lessen to 21.

By the South of the Chico Bank.

From 3 fathoms in the Outer Roads steer E. by S. as before, until you have 6 fathoms off Ensenada.

Before you lose sight of the town of Quilmes

N

you can see Point Lara, which is easily known by a grove on the side of the river.

S. E. of Point Lara there is a large ombu tree on Mr. Wright's Estancia, distant about 2 miles. E. S. E. of Point Lara is the Point and Mount of Santiago, easily seen at the distance of 7 miles.

2d. Having passed the Bank of Ensenada, which runs out about 5 miles from Point Lara to the N. E. by N., steer S. E. by compass until you find yourself 5 or 6 miles from land.

Before you lose

3d. When 5 or 6 miles from land, steer E. S. E. by compass to keep along the shore. lose sight of Point Santiago you will see the ombu tree of the Balandra to the E. S. E. distance about 14 miles, and one of those nearest to the river.

From this ombu the N. W. point of the Chico Bank bears N. 30° E. Keeping an E. S. E. course, after you have run a short distance you will see Point Atalaya resembling two mounts. Keeping still on the same course you will see many ombu trees, and when you have run about 6 miles you will see a large grove of them, where lies the town of Magdalena. The church of Magdalena is easily discovered, having two steeples, the largest at the east.

From this church the S. W. point of the Chico Bank bears N. 15° E. by the compass.

Between the Chico Bank and the land the least water you find is between the S. E. point and the coast; when the river is low you have, generally, about 17 feet.

Having passed the church you may keep farther from shore than six miles, as you have then passed the Chico Bank, and keeping on your course E. S. E. you will see four ombu trees, being the last you will see.

After passing the last ombu trees the shore is level, with shrubs, grass and reeds until you make Point Indio about 15 miles distant.

Point Indio is low level land with only one tree on it, and to the S. E. you can see two large groves of tallow-wood and espinillos.

These mounts are near Point Piedras and Point Indio.

From Point Indio the S. E. part of the Ortiz Bank bears N. 30° E. by compass, distant about 14 miles.

Situation of the Buoys on the Banks of Ortiz, Chico, Santiago or Ensenada de Barragan, and the Bank of Lara, which buoys may be seen 41 or 5 miles distant in clear weather and smooth water from the deck of a common-sized vessel.

1st. On the S. E. part of the Chico Bank there

is a red buoy in 3 fathoms water and muddy bottom.

From this buoy the church of Magdalena bears S. 15° W. by compass.

2d. W. by N. of the first, 4 miles distant, in 3 fathoms, sand and mud bottom.

3d. N. by W. of the second, in 1 fathom, 4 miles distant. This buoy is in the middle of the bank, which is less than one mile wide from N. E. to S. W. and serves for both channels N. and S. of the Chico.

4th. This fourth buoy is to the W. N. W. of the third, on the N. W. end of the Chico Bank, in 3 fathoms, muddy bottom, and bears N. 28° E. from the ombu tree of the Balandra or Point Atalaya.

On the Ortiz Bank are four black buoys.

1st. N. 30° E. of Point Indio, in 3 fathoms, muddy bottom, 13 or 14 miles distant, there is a black buoy.

.

2d. N. N. E. of the buoy on the S. E. side of the Chico Bank, on the edge of the Ortiz, in 3 fathoms, muddy bottom, 8 or 9 miles distant.

3d. N. N. E. of the third buoy on the Chico Bank, on the edge of the Ortiz, in 3 fathoms, muddy bottom, 7 miles distant.

4th. N. of the fourth buoy on the N. W. side

of the Chico Bank, in 3 fathoms, sand and mud, distant 7 miles.

On Santiago Bank is a black buoy.

On the N. edge of Santiago Bank of Ensenada, in 3 fathoms, muddy bottom, is a black buoy. From this buoy, which is 6 miles from the nearest land, Point Santiago bears S. 17° E. and Point Lara S. 60° W. by compass.

On Lara Bank is a black buoy.

N. 40° W. of Point Lara, distant 34 miles, on the N. edge of Lara Bank, is a black buoy, in 2 fathoms, muddy bottom. This bank is very narrow, being hardly half a mile wide and about four miles in length: when the river is low there is not more than from 7 to 9 feet of water on it. On the S. side is very good anchorage in 2 or 3 fathoms water, according to the state of the river, and is sheltered from the S. E. and E. S. E. winds.

2d. After running 30 miles, shift your course to W. S. W. and run for Point Indio.

3d. After making Point Indio, bring it to bear S. S. W. 8 or 9 miles distant.
