PURI'OSK ill this chapter to explain 

 some of the man}- remarkable \\a\'s in 

 which plants are enabled to scatter 

 their fruits and seeds. The chief agen- 

 {y cies which assist in carrj'ing out this purpose 

 are wind, animals, birds, running water, and 

 moisture in the atmosphere. We shall find that 

 man\- seeds are furnished with certain outgrowths 

 and ])eculiarities which are sj)eciall\' adapted to 

 the action of these agencies, with the result that 

 such seeds .are distributed far and w idc. We will 

 first examine some of those fruits which are scat- 

 tered by animals ; this end is generall)- attained 

 by means of hooks and cur\ed spines on the outside 

 of the fruit.
