Cleaning Fountains. 39 



it and the vessel up to the same height as the hole in the 

 side of the jar or flower-pot, therefore the hole in the side 

 of the rim of the vessel must not be quite so deep as the 

 height of the side of the saucer ; and above all the plug in 

 the flower-pot must be airtight. This fountain is cheap, 

 simple, and easily cleaned. Water may also be kept in 

 troughs, or earthenware pans, placed in the same way. The 

 fountains and pans should be washed and filled with fresh 

 water once every day, and oftener in warm weather ; and 

 they should occasionally be scoured with sand to remove 

 the green slime which collects on the surface, and produces 

 roup, gapes, and other diseases. In winter the vessels 

 should always be -"emptied at night, in order to avoid ice 

 from forming in them, which is troublesome to remove, and 

 snow must never be allowed to fall into them, snow-water 

 being most injurious to poultry.
