THE SECRET OF FLOWERS

It would seem never to have occurred to poet, editor, or

It was a German pastor, Christian Conrad Sprengel, at the 

 close of the eighteenth century, who first pointed out the true 

 significance of conspicuous flowers. His book, now a botanical 

 classic, attracted but little attention; his publisher did not 

 even send him a copy of it, and in discouragement he did not 

 publish the second volume, but turned from the study of plants 

 to that of languages. The title of the work. The Secret of 

 Nature in the Form and Fertilization of Flowers Discovered, 

 affords us the pleasure of knowing that he rightly estimated

 as is now well established, that the bright hues of flowers serve 

 as signals to attract the attention of nectar-loving insects fly- 

 ing near by. He was led to this conclusion very fitly by the
