NOTES ON FOREGOING EXPERIMENT. 



The birds were in perfect health during the winter. There was not a case of 

 frost bite in the coldest weather. This, doubtless, was due to the cotton-covered frame 

 which was let down, in front of the .roosting place, on cold nights. 



The number of eggs laid was greater than that from hens of the same variety, age 

 and strain, kept in a warmed house. 



The eggs, in early spring, were more fertile than those from hens kept in warmed 

 houses. 



When the weather was unusually severe the fowls were given snow instead of 

 water.

The birds in this experiment were kept in a warmed house. 



The average monthly maximum and minimum temperatures of the building 

 during the winter months are also given. This table (8) should be compared with 

 the foregoing table 7, when results will be found in favour of the system of keeping 

 poultry in unheated, well-ventilated houses. 



NOTES ON above EXPERIMENT. 



Rations fed to the above fowls were the same as given to the birds in the cotton 

 front house, as shown in table No. 7.
