Mr Maldonado, manager of one of the estates in the Isle of 

 Principe, caught large numbers of G. palpalis, by making his 

 labourers wear a black cloth, coated with bird-lime, on their

 given good results in other localities, for it has been shewn that 

 a single fly-catcher can capture far more flies in a single day 

 than twenty or thirty fly-papers.
