1. The data show a positive rectilinear association between the date of hatch and the date of first egg.

2. The date of hatch seemed to have a very slight association with the age at first egg (sexual maturity).

3. A decided curvilinear association was found between the date of hatch and the number of eggs produced before March 1.

4. The data show a positive rectilinear correlation between the date of hatch and spring egg production (March, April, May and June).

5. The date of hatch has a curvilinear association with total annual egg yield.
