THE NATURE STUDY C0UKSE. 



ants quickly remove all their belongings to a dark room and 

 leave the space ready to be uncovered and brushed out. If 

 orange-tinted or other non-actinic glass be used for roofing 

 for one of the dark rooms, the ants will go on working under 

 it for a time without much disturbance and then they may be 

 well observed. Food is placed in the lighted room in minute 

 bits. Try various kinds to find their favorites ; try morsels 

 of sweetened cake, crushed walnut, banana, etc. The sponges 

 referred to are their watering troughs; these should be scalded 

 once a week and filled with two or three drops of clean water 

 twice a week. In connection with a study of ants, read 

 Lubbock's " Ants, Bees, and Wasps."
