Table 6, which shows the total egg production, the dwarf egg 

 production and the number of dwarf eggs per 10,000 eggs for 

 each month of the two years combined. The data given in the 

 last three columns are shown graphically in Fig. 53.

Fig. 53. Diagram showing for the years 1911-12 and 1914-15 com- 

 bined the percentage of the yearly total egg production and dwarf egg 

 production which occurred during each month and the per cent, (x 100) 

 of the eggs produced each month which were dwarf. Solid line = 

 per cent, of total yearly egg production per month. Dash line = per 

 cent, of total yearly dwarf egg production per month. Dot-dash line = 

 the per cent, (x 100) of eggs produced during the month which were 

 dwarfs. 



An examination of the diagram or the data given in Table 

 6 shows that not only is the actual number of dwarf eggs small- 

 est during the winter, but that the number of dwarf eggs per 

 10,000 is also smallest. The irregular fluctuations of the fall 

 are due to the fact that three birds which produced dwarf eggs 

 because of a pathological condition of the sex organs laid
