A REVOLUTION IN EGG PRODUCTION 95 



hesitancy in placing the producti\'e possibility of White Leg- 

 horns, when handled as a business proposition, as an average 

 of two hundred eggs a year from each hen, in large flocks, 

 under proper care, with liberal feeding of balanced rations, 

 and with business days equalized in length, by artificial means, 

 sufficiently to enable the hens to manufacture their product. 



The figures given herein, on the comparative production 

 for the years 1913. and 1914, were chosen, for this purpose, 

 because the flocks matched better for these two years as to 

 the number of birds and the corresponding ages of the birds 

 making up the flocks. The two years being consecutive are 

 also better for comparison. 



As noted before, on Page 55, the birds in 1913 contained 

 pullets, one and a half year old, and two and a half year old 

 hens at the beginning of 1913; and pullets, one and a half 

 year old, two and a half year old, and a few three and a half 

 year old hens at the beginning of 1914. Thus there were a few 

 hens in the flock over four and a half years old at the begin- 

 ning of 1915. 



The author has records of much better production in 

 1911, which follow, and these are given to show that for great 

 production, under the best conditions with a natural day, the 

 age of the fowls has a good deal to do with the number of 

 eggs produced. 



The tables for 1911 show an average production, for the 

 whole flock, of one hundred fifty eggs. This flock contained 

 pullets of 1910, and fifty-nine pullets hatched May 18th, 1911, 

 and in this average, of one hundred fifty eggs, these 1911 pul- 

 lets are figured in as being matured birds at four months and 

 eighteen days old on October 1st, 1911. 



The tables for 1911 show an average production for the 

 adult fowls hatched May 30th, 1910, of one hundred seventy- 

 eight eggs. All these fowls were nineteen months old at the 

 end of the year of this record. 



The reader will thus be in a position to note that even 

 with the handicap of age of the adult fowls, and the lower 

 average for the year 1914 as compared with that of the year 

 1911, because of this handicap, the fall and winter production 

 of 1914-1915, with the aid of an artificial day, compares very
