Gas Buoys added in 1903 



Owing to the introduction of acetylene gas by the 

 Department, a large number of gas buoys were put in position 

 in November last ; the total number now between Montreal 

 and Lake St. Peter is 16, but 12 of these were placed between 

 Montreal and Sorel, for the benefit of the late arrivals among 

 ocean going steamers. The advantage of these gas buoys 

 has been said to be twofold, the steamers are enabled to 

 proceed at night as well as during the day, going to and from 

 Montreal without any unnecessary stoppage, during the autumn 

 navigation.
