OHIO KXI'KKIMKNT STATION: BULLETIN 208 



With the patience and cunning that in time become characteristic 

 of the devoted photographer, we succeed in catching, with the cam- 

 era, a very-much-alive "chuck" indulging in a day-dream in the 



entrance to his 

 b u rrow, (See 

 frontispiece). 



Later this same 

 burrow shall have 

 dropped into its 

 deep passage a 

 small ball of rags 

 or twine saturat- 

 ed with bisul- 

 phide of carbon, 

 after which the 

 entrance must be 

 closed s e c u rely 

 with a banking of 

 soil firmly tamp- 

 ed or pounded. 

 The deadly pene- 

 trating vapor or 

 gas from this 

 dangerous, explo- 

 sive chemical, will 

 fill the burrow and 

 the inmates will 

 lapse into a sleep 

 during which 

 there will be no 

 dreams of mis- 

 chief for the 



Fig. 4. They promise to be good. future.

 are shown by photographs on th^ following pages and are accompan- 

 ied by brief descriptions and remarks which will readily enable the 

 planter to decide which form or means of protection will best suit 

 his conditions.
