method is of so much importance, and the 

 study of fruits with a view to discovering their 

 names is such a valuable exercise for students, 

 that I have felt constrained to include the 

 Warder classification practically entire in this 

 volume. 



Of course, to do this some revision seemed 

 necessary. First, it was desirable to add 

 many of the newer and most important varie- 

 ties, and, second, it seemed possible to cut out 

 a good many of the old varieties which have 

 now been lost from Warder's original list. 

 Warder's list of varieties has, therefore, been 

 revised more or less in both these directions, 

 and appears in the remodeled form below. 



In the elimination of obsolete varieties I 

 have been especially assisted by Mr. William 

 A. Taylor, of the United States Department 

 of Agriculture, to whom my most grateful 

 acknowledgments are due. Mr. W. M. Irwin 

 and Mr. W. H. Ragan, also of the Depart- 

 ment of Agriculture, have assisted more or 

 less. In this part of the revision it appeared 

 that about forty per cent of the names in 

 Warder's list are now obsolete ; about 

 thirty per cent are of uncertain identity, or 

 cannot now be either established or discarded
