late in May and commenced laying in October, continuing 

 laying moderately, through November and December. The 50 

 birds were mated in November with 2 cockerels, that did not 

 quarrel, and these matings continued through the 10 months' 

 test. 



Three of the 50 died and did not do a full year's work, and 

 7 others laid irregularly and are not considered in the data 

 given below.

During the first lo days in January, all of the eggs laid by 

 the 40 birds were saved and incubated and the results noted. 

 The same was done through the first 10 days of each succeed- 

 ing month, ending with October. All of the eggs laid during 

 the several lo-days periods, were incubated, none were rejected 

 because of lack of size, irregular shape, or defective shells, as 

 would have been done in ordinary selection. This, of course, 

 reduced the percentages of hatchable eggs in all the periods. 

 The results are given in the accompanying table.
