Testing Eggs by Electric Light. 



This picture is from a photograph of a couple of candling- booths, designed by the 

 author of "Eggs in Cold Storage." Each candler works by herself in a small room 

 closed on three sides by matched stuff, and on the fourth or front side by a heavy 

 curtain to keep out the light. These curtains are seen pushed back in the picture, so 

 that the interior of the booth may be photographed. The white boxes in the center of 

 the booths are candling boxes. They are pierced with two holes, and have an electric 

 light suspended inside A shelf, showing in the picture, runs around three sides of the 

 booth at a convenient height above the cases, for supporting fillers, dividing boards, 

 nails, hatchet, etc. The barrel is for the litter of various kinds (old newspapers, etc.) 

 which alwaj's accompany country packed eggs. The pail just above the barrel is for 

 rotten eggs. Cork shavings may be seen in the box between the two booths. The 

 advantage of each candler working independently will be appreciated by all familiar 

 with the work. The concise arrangement of this style booth makes a great saving in 

 space as compared to the ordinary candling room.
