is made into a paste so that it may be easily poured. The sulphuric 

 acid solution is made by putting four ounces of crude acid into a gallon 

 of water. The amount used of the two mixtures will vary with the 

 size of the nest. Equal quantities of each are employed. First pour 

 the bichlorid into the main entrance to the nest through a funnel and 

 follow with an equal quantity of the diluted sulphuric acid. Close all 

 the entrances to the nest and the chlorin gas generated penetrates 

 through the galleries of the nest and kills the ants. At least this is the 

 belief of the exploiters of this remedy."
