Tlie aim oE this book is two-fold — to give all necessary instruction on the cultivation of the bush- 

 fruits, and to provide a cyclopedia of reference to varieties, species, insects, and diseases. Every 

 variety of the various fruits is fully described, this being the first effort to collect all information 

 about varieties of all these fruits since the time of the Downings. In this respect, the book will 

 always be a standard authority. The varieties are arranged alphabetically under various natural 

 classes or groups, but a very full index refers instantly to any variety. The cultural directions are 

 full and clear, and are entirely separated from the descriptions and technical matter. Full instruc- 

 tions are given for the evaporating of berries.

THE EVOLUTION OF OUR NATIVE FRUITS. 



By L. H. Bailey, Cornell University. 



4S5 Pages— 125 Illustrations- $2.00. 



In this entertaining volume, the origin and development of the fruits peculiar to North America are 

 inquired into, and the personality of those horticultural pioneers whose almost forgotten labors have 

 given us our most valuable fruits is touched upon. There has been careful research into the history 

 of the various fruits, including inspection of the records of the great European botanists who have 

 given attention to American economic botany. The conclusions reached, the information presented, 

 and the suggestions as to future developments, cannot but be valuable to any thoughtful fruit- 

 grower, while the terse style of the author is at its best in his treatment of the subject.
