SELECT LIST OF FRUITS. 



The select list of fruits which are particularly recommended for a 

 moderate collection, have been designated by a star throughout this 

 work, and also throughout the Index, all these having been satis- 

 factorily proved ; but, as a considerable proportion of the highest 

 character are new, and of recent introduction to our climate, or not 

 having been, as yet, satisfactorily proved, and are therefore excluded, 

 it must be evident that this list will, from time to tn,v;, require a 

 revision. The list of the long-keeping or winter fruil* hould be 

 increased by duplicates, or by additions, and beyond th* proportion 

 of the more transient or summer fruits.
