PHEASANTS IN COVERT AND AVIARY 



gaseous disinfectants, several of which are prepared as 

 follows : — 



Sulphurous Acid Gas 



This is a very useful gaseous disinfectant, and one that 

 is very extensively employed in houses by local authorities, 

 as a means of disinfecting the premises, when there has been 

 an outbreak of some disease such as scarlatina, small-pox, 

 and so forth, in the human subject. 



The coops require to be placed in a close shed, and 

 " Flowers of Sulphur," say a quarter of a pound, is allowed 

 to burn, by throwing it on the top of some red-hot coal, con- 

 tained on a shovel, the shed meanwhile having all windows, 

 doors, etc., closed. 



Chlorine Gas 



This is a powerful disinfectant and particularly suitable 

 when a gaseous disinfectant can be applied. It is made 

 by taking a mixture of manganese dioxide and common 

 salt, say half a pound of the former to a quarter of a pound 

 of the latter. A little oil of vitriol is then poured upon it, 

 and the shallow tin containing the mixture placed on a stand, 

 so that it can be gently heated with the flame of a spirit lamp 

 below. The gas is evolved, and will fill the shed, provided 

 the place is rendered air-tight. It is needless to remark that 

 no live-stock must be left inside, as both are very suffocating 

 gases. 



The use of solid disinfectants about pheasantries in the 

 rearing-field is objectionable, as the birds are very liable to 

 pick up the gritty particles contained in such disinfectant 



powders, which in all probability will lead to death.
