THEIR MARVELLOUS INDUSTRY 
case the body of all orders is solidly built, with the thorax 
and head protected by spikes. 
Much as I disliked the saubas for the endless trouble 
and suffering they inflicted upon me, I could not help 
admiring their marvellous industry and energy. No agri¬ 
culture is possible where they are to be found, and even 
where they do not exist in Central Brazil, if agriculture 
were started they would soon invade the territory and 
destroy everything in a short time. Foreign plants do 
not escape. No way has been found yet of extirpating 
them.
