Test Xo. 0. — With five White Leghoru heiis. Cock bird separated from hens on 

 June 23, 1904. E^g-s put into incubator five days later and thereafter for twenty days. 

 Details are as follows : — 



It is interesting to note the result of the two tests. In the first test, Xo. S, fertili- 

 zation was strong enough in 6 eggs laid on the 5th day, after removal of the male bird 

 from tlie breeding pen, to hatch out two healthy chickens. The last trace of fertilization 

 is found in an egg laid eleven days after removal of the male bird. Examination of 

 tliis egg, in course of incubation, showed a fairly well developed chicken dead in the 

 shell. It had evidently died in progress of development from weak gennination. Xo 

 further evidence of fertilization is found in this test. 



In the second case, test Xo. 9, strong chickens are hatched from eggs laid on the 

 eighth day after removal of the male bird and fairly strong and healthy chicks from 

 eggs hi id on the tenth day after separation. From the three eggs laid on the eleventh 

 day after separation a weak and infirm chicken was hatched. After this there is no 

 trace of fertilization. Results seem to endorse the advice given in reports and corre- 

 spondence of previous years, to the effect that it is not advisable to set eggs for hatching 

 winch are laid on or after the fifth day of removal of male from breeding stock. 



Another interesting result which made itself evident was the comparative unim- 

 paired condition of the unfertilized eggs at the conclusion of the 21 days' tests. 

 These unfertilized eggs were taken from the incubator on the 22nd day, after they 

 were put into the machine. During that time they were subject to the^ ordinary tem- 

 perature of 103 degrees of heat usually maintained for the hatching of chickens from 

 fertilized eggs. On examination, these unfertilized eggs wore found to be in as equally 

 good condition and flavour — if not better in numerous instances — than the majority
