PREFACE. 



The illustrations showing the cave-culture of mush- 

 rooms are from my <( Parks, Promenades, and Gardens of 

 Paris/'' And the frontispiece is after two large cuts of 

 the mushroom caves of Paris, which appeared in the 

 Illustrated London News some time after the appearance 

 of my work. The illustrations of edible fungi are by 

 Mr. WORTHINGTON G. SMITH, who knows and draws 

 these interesting subjects so thoroughly well; and the 

 other figures are by Mr. HODGKIN.
