Does anyone remember Candling eggs? Today we added this little gem to the State Library's KGI Online Library, "Candling and Grading Manual for Shell Eggs." Published in 1951 this booklet gives a full description of candling.

The preface states, "This manual is prepared for use in properly training persons and to develop skilled candlers and graders. It may also be used in developing a more thorough knowledge of the egg, the importance of its care, and factors which constitute quality."
Cool little read.
