During my residence in India, I have had many opportunities of 

 judging how far the various modes of packing plants for their 

 voyage to Europe are successful, or otherwise ; and subsequently 

 having been so fortunate as to bring a considerable number of living 

 plants to Europe, I have acquired additional experience upon this 

 subject, from a personal inspection of the gradual influence of those 

 successive changes of climate to which plants are exposed during 

 their transmission. A further occasion, almost a year ago, of 

 seeing the practical result of such directions as my own experience 

 had suggested, has induced me to believe that some hints upon the 

 most secure way of preparing plants for a voyage may not be 

 without interest to the Horticultural Society. 



The subject may be considered under the four following heads ; 

 1. the preparing plants for the voyage ; 2. the packing them ; 3. their 

 treatment during the voyage; and, 4. their management upon their 

 arrival. 



With regard to preparing plants for a voyage, it is of great import- 

 ance to attend to the age and strength of the subjects, a consider- 

 ation which does not generally meet with the attention it deserves. 

 Very often plants of tender age, or already weak and sickly, or 

 grafts only recently, or imperfectly united to their stock, are 

 crowded together hastily into the cases in which they are to
