INTRODUCTION 
is a topic rarely dealt with satisfactorily by writers on 
vegetable gardening. This book attempts to remedy that 
deficiency. 
In connection with this particular phase of the subject , 1 
it should be borne in mind that horticulture is not am 
exact science and that opinions are judgments rather than 
facts. The best posted experts differ on the subject of 
relative merits of the different varieties. However, the ; 
observations recorded in the following pages are based on 
intimate studies extending over many years, in many 1 
sections of the country. In the absence of other records 
they will serve as the starting point for those who are i 
anxious and willing to help put vegetable gardening on a 
more nearly scientific basis. 
In an endeavor to make this book serve millions and to i 
make it truly useful to gardeners in all sections, a great 
deal of expert advice was sought. In incorporating it in 
the book grateful acknowledgment is due Mr. Howard : 
M. Earl for helpful hints on all topics. In making I 
special reference to Pacific Coast conditions, the excellent 
work of Professor Wickson on California vegetables has 
been freely consulted. A quarter century after its first > 
edition, it must still be considered the leading treatise on 
the subject. Particular thanks is due Mr. Leonard ■ 
Barron, Editor of The Garden Magazine, whose generosity 
in putting at my disposal thought, time, and everyready ! 
craftsman’s advice has helped a great deal in making this 
work complete and authoritative. 
With this goes the hope that this book may help to 
really make America a land of gardens; to sufficiently 
interest those who have never before made a garden, to 
dig, rake, sow seeds, and put plants into the ground; to 
encourage those with experience to do more gardening and 
to help the expert to still better results.
