fco a much greater extent, and in the last period the birds laid 

 only 26 per cent, of first grade eggs. A third pen, which in 

 the first period produced 17 per cent, of second grade eggs, 

 lost heavily, and in the fifth period had produced 64 per cent, 

 of second grades; thereafter it slowly improved, and in the 

 final month produced 78 per cent, of first grade eggs.

 of single pens, results have been collected of the number of
