done with 2 beacons placed in lineonthe Argentine coast 



and four buoys. 



This bad bar of Almiron Grande having been passed 

 and after the two arms of the Almiron Island* have joined 

 - again, the channel becomes wide and deep, having a depth 

 of 22 meters in, the very poii of Paysandii (Sheet />). 



There are on the Oriental shore near the Sacra» creek 

 several shoales which remain above water when the river 

 is low but which offer no danger to the navigators as they 

 are ouside the general course. 



Different is the shoal situated above the port of Paysanchi 

 and wicb is called the shoal of the «Curtiembre» (Tannery). 

 On it grounded the river steamers «Helios» and Paris». 

 It can be avoided during day time, navigating a little 

 westward of the line formed by the two tower of the Church 

 of Paysandii. At present the shoal is marked by a buoy, 

 which has been placed by this Commission. 



The channel widens again till it reaches the lower end of 

 the «San Francisco » island in front of the creek on the 

 Oriental shore of the same name. 



Here again it presents two arms to the navigation (Sheet 

 K). The Eastern arm was before the one followed by the 

 sailors, till it was discovered, that in the Western there 

 is 2 feet more of water so that at present the first named 

 is only used by vessels of small draught, which go to load 

 lime or limestone in the River Queguay. The channel at 

 the North point of the San Francisco» Island, which in 

 days before formed the pass indicated by this name, is now 

 no longer used. 



The Western channel has been surveyed in the years 

 1895 and 1901, no notable differences in its configuration 

 has been found. 



It has a depth of 6 feet and being curved caused the fre- 

 quent groundings that have taken place at this point. 

 Upstream of the bar proper exist some sand banks, which 

 beginning at the South end of the Queguay island, cross the 

 river in the direction toward the great bank at the North 

 point of the Hornos island. 



The bar forms a weir when the river is low and the water 

 flows in this case round the Northern point of the island of
