ters, by means of luminous buoys will be completed and 

 consequently navigation will then be as easy at night as 

 by daytime. 



In the part of the river under description ( from the river 

 ( xualeguaychu to its mouth) there are only two places in 

 the navigable channel where the depth is less than 18 feet. 

 They are the « Barrial » bar and the «Punta Caballos» 

 bar. 



Before arriving at the mouth of the River Gualeguaychii, 

 the navigable channel disappears to be found again at some 

 distance. Those two parts of the channel are separated by 

 a bar formed by sand and thin mud, to which latter the 

 bar owes its name. At this bar, which must be crossed 

 in order to pass from one channel to the other, there is 

 only 13 feet of water at exceptionally low tides. After the 

 surveys have been concluded, it has been found, that the 

 bar becomes narrow towards the North forming a gorge 

 consisting of sand being only 800 wide. It is at this place 

 that the channel to be excavated, for joining up the deep 

 waters, has been projected. The cube to be dredged is 

 about 300.000 M 3 . After this dredging has been carried 

 out the new channel will be marked by luminous buoys, 

 so that vessels will pass safely. 

 pu.nta caballos After the last described bar. the only shallow place in 

 The River Uruguay till its mouth is the < Punta Caballos » 

 bar. It is situated a little above the mouth of the Rio 

 Negro and is also formed by a long and narrow bar 

 which blocks tlie navigable channel. The material to be 

 dredged is sand, the quantity to be extracted being only 

 20.095 M 3 . After this bar has been dredged The channel 

 formed will also be marked by luminous buoys. 



Both channels will be dredged to a width of 200 mis., 

 and as the Argentine Governmenl lias just made an arran- 

 gement with a firm of contractors, to execute this work, it 

 is supposed thai before May of next year There will be in 

 the River Uruguay from Colon to its mouth the depth as 

 has been established in the project of this Ministry of Pu- 

 blic Works for the improvement of the navigability of 

 This river.
