Are you interested in Plants 

 As well as in Birds and Animals? 



Then you ouahl to read.. . JHE PLANT WORLD 



The only Popular Journal of its kind in America. The fifth volume , 

 beginning in January, 1902, will have a series of articles on the prom- 

 inent botanical institutions of the country, illustrated with beautiful 

 photographs. Possibly, too, you will be interested in the eight page 

 Supplement which takes up in proper botanical sequence and discusses 

 from mouth to month all the families of flowering plants, telling their 

 distinguishing characters, economic uses, and where they are found. 

 It is copiously illustrated with text cuts and half-tones. 



THE PLANT WORLD is an original Magazine, edited for the 

 botanist and plant-lover alike, but technical matter is excluded. 

 Everyone is welcome to contribute to its columns. 



If you knew you could secure a sample for a one cent stamp 

 wouldn't you send for it? And when you found it only cost a dollar 

 a year wouldn't you feel sort-y because you hadn't subscribed earlier? 



We would like to tell yon about the other publications we handle, 

 but The Plant World itself will do that if you will let it make your 

 acquaintance. Address
