PREFACE TO THE FOURTH EDITION. XI 



To cultural directions we have little to add. A 

 well made rhododendron-bed will need no renovat- 

 ing in a score of years : but if the plants seem to 

 lack nourishment, well rotted cow manure may be 

 applied with beneficial result. 



As we said years ago, so now, when the promise 

 of bloom for the coming year is greater than ever 

 before, we say to all lovers of flowers, " plant rho- 

 dodendrons." 



Glen Eidge, January, 1876.
