AGRICULTURE ON THE PACIFIC SLOPE 



enough between them for the ants to move about. Place 

 the glass on a piece of wood in an agateware pan, and pour 

 in some water. This is to keep the air moist and prevent 

 the ants from escaping. Now dig up an ant nest and place 

 some of the ants, together with the young (which look like 

 white grubs), on the glass in the pan. Cover the pan with a 

 piece of glass, and over this put a piece of cardboard to keep 

 out the light.

 ing on the Pacific slope. (The smaller figure is a little less than natural 

 size.) 



Better still, get a sheet of transparent lemon-colored 

 celluloid, lay it over the glass cover of the pan, and on it 

 place another glass cover. The ants behave in the yellow 

 light just as if they were in darkness, and can be watched 

 without taking off the cover. 



The ants should be fed with honey and bits of meat, 

 which may be placed on the glass strips. 



A very injurious ant which may spread rapidly on the 

 Pacific Coast is the Argentine ant (figure 115).
