 the improvement of the Upper Uruguay could be initiated. 



Willi reference to the workmen, as labourers, sailors, J^ffr *|» n ch a 

 miners, firemen, etc. it can be said that They arc of a very ^ci^sofiower

The ordinary buoys which are intended to be placed are 

 of about 0,75»i M 3 of displacement, and will he anchored 

 with chains of 25 milimeters diameter and of a length 

 equal to double the depth at the highest river. 



The towers or beacons for indicating directions have been 



80X80 

 designed of angle iron - -j~- - milimeters and are 8 meters 



high. 



The advantage of their use ( besides an other principal 

 one, which will be indicated further on ) is that they can 

 be changed into a luminous demarcation under economical 

 conditions. 



The huts, which are provided for guards, are destined 

 for the watching and the service of maintenance of the 

 demarcation of the principal bars of Chapicuy, Hervidero 

 and Corralito. 



In order to estimate the cost of the luminous buoys to 

 the Port of Colon, which port is navigated by the river- 

 steamers during night time, the prices of the contract with 

 Messrs. Dirks & Dates of the 10 th of January 1899, for a 

 similar work executed in the River Plate, have been taken.
