To the attentive eye the sight of industrial insects exhibiting 

 the most refined art in their labours is a spectacle both 

 strange and sublime. Human Reason is confounded by 

 Instinct thus raised to the highest pitch of which Nature can 

 offer an example, and the perturbation of intelligence 

 increases on observing, patiently and minutely, the details 

 of the life of those creatures most highly endowed with 

 instinct. K. Blanchard.
