also, in common with our whole country, I am particularly 

 indebted ; also to those numerous individuals whom I have 

 elsewhere named. 



England, by the exertions of her most intelligent and 

 influential men, and by her societies, particularly that of 

 London, has, confessedly, done a great deal for the ad- 

 vancement of the science ; and no man in England has 

 probably done more in its aid than the late Thomas An- 

 drew Knight, Esq., lately the distinguished president of 

 the London Horticultural Society, with the exception only 

 of Mr. Loudon, who, for the extent and usefulness of his 

 writings on this and other subjects, may be deemed one of 

 the most remarkable men of the age. In profound horti- 

 cultural researches, who more distinguished than Professor 

 Lindley and Mr. Thompson, in this decisive day ? 



To the descriptions of the fruits of the divers climes, 

 which are adapted to the various sections of our country, 

 from the north to the .south, and bordering on the tropics, 

 I have added the useful vegetable plants, and the trees and 

 plants of ornament. Also, I have added a select list of 

 fruits, or a recommended list, of a limited number, of 

 those kinds only, which, having been already tried and ap- 

 proved in our climate, can be especially recommended. 

 To many of these I have prefixed an asterisk, or star. But 

 as many of the new kinds, of the highest character, have 

 never as yet borne fruit in our country, and are therefore 

 excluded, it must appear evident that this list will, from 

 time to time, require a revision. The select the very 

 best possible list, and such alone as we should most of all 

 be desirous of offering the public cannot be formed until 

 all those new and excellent kinds, which this extraordinary 

 age has produced in Belgium, are put to trial in our cli- 

 mate. Their names, their numbers, and their excellence, 

 constitute a host, in all probability far greater than all that 

 the former ages had ever produced. For their introduc- 

 tion to out own country, much is due to the individual en- 

 terprise of our own citizens, to Dr. Van Mons, of Belgium, 

 and much also to the distinguished liberality of Mr. 

 Knight, and the London Horticultural Society.
