TERRA RI A 



143 



The dry-temperate terrarium is naturally the simplest in construction, 

 the 1 principal requirements being open ventilation and a small drinking 

 pool with cement edge and mirror bottom. This seems to be necessary 

 to some of the creatures, as they are accustomed to seeing the sky 

 reflected in water and without this they do not at first recognize it as 

 water.
