Where a system of checking the work of iinskilled individual can- 

 dlers was enforced, the number of bad eggs graded by them as 

 good was ordinarily no greater than that found with skilled labor 

 (Table 7 and fig. 2). To accomplish this result with untrained labor 

 the individual candlers were instructed to place all eggs which were 

 difficult to grade with the rejects or in a container b};^ themselves. 

 The rejected eggs from the unskilled crews were recandled by the 

 foreman or another expert, and a record kept of the good eggs thus 

 reclaimed. If an undue number of edible eggs were found, the in- 

 spector called the attention of the individual candler to the fact, and 

 gave him the instruction necessary to enable him to avoid fu- 

 ture mistakes. The same routine may frequently be followed in the 

 case of skilled labor in order to maintain a high standard of accu- 

 racy, and to locate a lack of knowledge on the part of any individual. 

 By this procedure some good eggs were found to be present always 

 in the rejects, especially in those from inexperienced candlers. The 

 reverse should be avoided. From 39.6 to 66.6 eggs per case were 

 salvaged by recandling the rejects from inexperienced candlers thus 

 instructed. If 10 per cent of these eggs were found to be bad on
