Rocks. The Rhode Island Reds, compared with the Barred Plymouth 

 Rocks and the White Wyandottes, show a less difference between the 

 two months. In this connection it may be noted that the mean value 

 of the February egg production for eight years, as given for the Barred 

 Plymouth Rocks by Pearl (7) if reduced to a basis of 31 days is 12.03, 

 approximately, or slightly higher than for January, which is 11. 71, The 

 mean egg production for February (28 days) for the entire flock of our 

 Rhode Island Reds has always been higher than for January. 



Table VIII is similar to Table VII, but we have utilized the larger 

 numbers made available by including in the January and February 

 means the records made by birds beginning to lay as late as January i. 

 The essential result is the same as shown in Table VII.
