from one blossom to another, loaded with 

 yellow dust ; gay-coated insects seem dancing 

 on the sunbeams, as if in quest of a per- 

 petual spring ; and butterflies emulate the 

 colours of those splendid flowers, on which 

 they shut and open their gorgeously tinted 

 wings. And yet, though seemingly intent 

 on merely varying their sources of delight, 

 they have all and each, a duty to perform 

 in the magnificent museum which they are 

 designed either to embellish or to benefit. 

 Functions are carried on by them, which, 

 although presented to the senses in their 

 eflFects, the mind is unable to comprehend. 

 And not more truly does one part of an 

 exquisite piece of machinery fit into the 

 other, than the structure of even the smallest 

 flower is adapted to the winged creatures 

 that frequent it ; and those winged creatures 

 to the simple flower, their fit dwelling-place, 

 "The little insect's world of joys or cares."
