PREFACE ix 



for his help and for the interest he has taken in the 

 matter, but also to thank him for the greatly enhanced 

 value that the book receives by going forth to the public 

 with the imprimatur of so high an authority on economic 

 botany. 



The author has also to express his acknowledgments 

 to Professor Oliver and the authorities of the Kew 

 Gardens for the advantage of being able to illustrate the 

 book with some scientifically accurate figures. The 

 engravings of the coffee, the cacao, the tea, the orange, 

 the nutmeg, the cinchona, the rice and the tania plants 

 are copied from the guide to the Royal Gardens. The 

 illustration of the coca plant and the diagram of the 

 vanilla flower are from the Kew Bulletins ; it is proper, 

 however, to remark in regard to the last-mentioned, that 

 Fig. 4 is an improvement on the original, as it shows 

 the lamellum pushed up under the anther. The other 

 illustrations are from the author's drawings.
