shown in B may be adopted, if desired, viz., a movable wooden 

 shelf under the perches to catch droppings. House " B " would 

 take a third perch, if necessary, and would then accommodate 

 at least 30 birds. In both A and B the kerosene receptacles in which 

 the legs of the houses stand should be fairly deep, and only partly 

 filled so that the birds may not be able to get at the kerosene. 



The approximate cost of the material for house A built of uralite 

 as shown would be £5 10s. 



House B would be less ; and both would be less still if built of 

 ruberoid. The difference between the cost of wood and iron and 

 uralite is not great.
