of from the outside Inwards. The writer is indebted to 

 a friend for this plan, which is as helpful in practice as it 

 is sound in theory. 



In order to make the most of the Euston system, the 

 eggs should be put under hens at Intervals, which will 

 ensure a setting of eggs, partially incubated, being ready, 

 in case of emergency, at any time during the hatching 

 season. It often happens during very wet weather that 

 birds will desert their eggs for a time and return when 

 the young birds Inside them are dead. If the keeper 

 has some eggs under hens at this time he can distribute 

 them very profitably to those birds which would otherwise 

 sit without effect. 



The hatching of late second nests should always, when 

 possible, be accelerated by ten or twelve days. 



Very late birds, even if they live, seldom grow proper- 

 ly, and invariably lay very late the following season. 

 Their eggs also being small and few In number, the 

 probability is that the offspring is none too strong. The 

 fact that these birds can be hatched by artificial means 

 ten or twelve days earlier than would be the case under 

 ordinary circumstances, makes a considerable difference 

 to their growth and laymg power. 



The Euston system will be found useful in other cases 

 which crop up during every ne^ing season. 



Keepers should be encouraged to keep statistics of all 

 the ne^s they find, and If maps of their beats, showing 

 the fences, are provided for them, the ne^s can be 

 marked down and none should be forgotten. 



The date on which each bird begins to sit should be 

 carefully noted, as it may become of the utmoit im- 

 portance later on.
