V\g. 9. Diagram showing the average egg production in each month 

 •of the year based on nine years trap nest records. The &gg production 

 curve is given by a solid line. The dotted line represents the average 

 maximum New York price of eggs for each month of the year 1907 

 as taken from the Crop Reporter. The scale of egg production is given

 given the scale of egg prices in cents per dozen.

 tion of between 4 and 5 eggs in November the Hne rises rather 

 sharply to an average production of nearly 12 eggs per bird in

 sharply to a maximum of a little more than 16 eggs per bird 

 for the month of March. From March on the line drops very 

 steadily forming almost a straight line until it reaches a low 

 point in October. There is a slight deviation of the line upward
