and rough an implement, a pliant stock of grass, 

 gently insinuated into the caverns, will probe their 

 windings to the bottom, and quickly bring out the 

 inhabitant ; and thus the humane inquirer may grat- 

 ify his curiosity without injuring the object of it. 

 It is remarkable that, though these insects are fur- 

 nished with long legs behind, and brawny thighs 

 for leaping, like grasshoppers ; yet, when driven 

 from their holes they show no activity, but crawl 

 along in a shiftless manner, so as easily to be taken : 

 and again, though provided with a curious apparatus 

 of wings, yet they never exert them when there seems 

 to be the greatest occasion. The males only make 

 that thrilling noise perhaps out of rivalry and emu- 

 lation, as is the case with many animals which exert 

 some sprightly note during their breeding time : it 

 is raised by a brisk friction of one wing against the 

 other. They are solitary beings, living singly male 

 or female, each as it may happen; but there must be 

 a time when the sexes have some intercourse, and 

 then the wings may be useful perhaps during the 

 hours of night. When the males meet they will fight 

 fiercely, as I found by some which I put into the 

 crevices of a dry stone wall, where I should have 

 been glad to have made them settle. For though 

 they seemed distressed by being taken out of their 

 knowledge, yet the first that got possession of the 

 chinks would seize on any that were obtruded upon 



them with a vast row of serrated fangs. With
