which, the coDe does not fall : the caterpillar has taken 

 the precaution to sustain it by some threads of the 

 same species with its border. When the cone is finished, 

 the caterpillar applies herself to disengage aad trans- 

 sport it from its place. She has left a small aperture at 

 one end of it. She causes her head to come out at this 

 opening, bears it forward, seizes a part of the prop with 

 her teeth, and by an effort draws the cone to her. The 

 threads that hold it give way, and the caterpillar carries 

 her little house about with her as the snail does her 

 shell. Behold her walking ; her march is a new my- 

 stery. It has been said that all caterpillars have at least 

 ten legs : this is absolutely without any, and shews us 

 what ah opinion we ought to entertain of such naturalists. 

 Let us lay in her way a finely polished glass, placed per- 

 pendicularly. She is not in the least retarded by this, 

 but climbs over the glass as on a leaf. By what secret 

 art is she enabled to cleave to it, for she has neither legs 

 nor claws to grapple it ] You have seen caterpillars that 

 spin little heaps of silk which they fix themselves to. 

 Our miner spins the like, at certain distances, according 

 to the track she is to pass over. She seizes one of these 

 heaps with her teeth, which becomes in part a support 

 for her; she draws the cone to her, and carries it to- 

 wards the little heap : fastens it to it ; thrusts her head 

 forwards : spins a second heap : fixes herself to it in the 

 same manner as to the first ; makes an effort to discharge 

 the cone, which she effects, drags it towards the new 

 heap, fastens it likewise to it, and this second step being 

 taken unravels to you the secret of her ingenious me- 

 chanism. By this means she leaves on the bodies over 

 which she passes little tracks of silk, which she spins 

 from space to space. When , she has arrived at the 

 place she is inclined to fix herself at, she here stops the 

 cone intended for a habitation, and places it in a verti- 

 cal situation. There afterwards issues from it a very 

 pretty butterfly, as richly clothed, and of the same 

 genus, as those of other miners.
