wool placed in one of the upper chambers of the nest and the hole

and then poison the rest of the inmates of the nest. 
Specimens of the various forms of this Termite, preserved in 
spirit, and the queen chamber in the nest, as well as information about 
the nesting habits, distribution and damage caused, will be most wel- 
come if addressed to
