It is made by taking Copperas one-half ounce, 

 Sulphate of Soda four ounces, Gentian Root (pow'd) 

 one-half ounce, Phosphate of Soda two ounces, and 

 pure Creosote (Beechwood) one dram. The Creosote 

 must first be rubbed well (in a mortar) with about 

 forty grains of Calcined Magnesia, (otherwise it 

 would not mix with water.) Add two quarts of 

 warm water and follow with the other ingredients. 

 Set away in a cool place, and use a tablespoonful to 

 a gallon of the bird or birds' drinking water.
