How to Preserve Eggs. 



To each pailful of water, add two pints of fresh 

 slaked lime and one pint of common salt; mix well. 

 Fill your barrel half full with this fluid, put your eggs 

 down in it any time after June, and they will keep 

 two years, if desired. A solution of silicate of soda, 

 commonly known as water glass, is also used for the 

 same purpose.
