Trials with White Leghorns from 1947 to 1952 showed that more accurate selection could be based on average length of laying cycle and age at first egg than on total production for the first laying year. To apply this method, careful observations must be made for a few months while the birds are trap-nested.-T. D. Bell.See also Absts. 5780, 5917, 5919, 5928, 1013.
