PREFACE 



they have evidently been written by people of no training 

 and poor judgment." I desire to state in this connection 

 that the descriptions and statements herein contained ad- 

 here strictly to the authoritative writings of Professor Peck, 

 Dr. W. A. Murrill, the late Professor G. F. Atkinson of 

 Cornell University and Professor C. H. Kauffman of the 

 University of Michigan. 



I consider myself fortunate in being able to offer to readers 

 the original colored plates which were painted by Miss Mary 

 E. Eaton, Artist to the New York Botanical Garden. 



Dr. N. L. Britton, Director of the New York Botanical 

 Garden, has given encouragement and co-operation which is 

 gratefully acknowledged. Thanks are also due to Dr. M. A. 

 Howe, Assistant Director of the Garden, for his kind assist- 

 ance in paving the way for the preparation of this little book. 

 Acknowledgment is also made to George S. Godard, State 

 Librarian of Connecticut and to C. J. Galpin, Ph.D., of the 

 U. S. Department of Agriculture, for their courtesy in per- 

 mitting me to use some of the half-tones in this book. Dr. 

 Howard A. Kelly of Baltimore has favored me with his in- 

 terest and valuable suggestions.
