94 MYSTERIES OF THE FLOWERS

 makers in carnival time. 



The perfect adjustment of the apparatus and its

 some deus ex machina, devised it, and created it 

 all out of the delicate and fragile material of which 

 all flowers are built. But as such speculations are 

 unscientific we must postpone them till such time 

 as we shall have fuller knowledge from which to 

 make deductions. 



Most of the floral mechanisms are economic de- 

 vices to save pollen and to make the most of the 

 precious stuff. The great pine-trees may scatter 

 their pollen by the bucketful upon the wind, and 

 the Indian corn may throw it away in wanton pro- 

 fusion, but the flowers seem to have learned to be

 a tube around the undeveloped pistil, and shed and
