1214 InTRODUCTION 
To all who have so freely contributed of their best, the compiler 
would record his obligation and appreciation ; particularly to those 
personal friends from whom he has exacted and received tribute, 
chief among whom are Mr. Paul Work and Mr. A. E. Wilkinson, 
of Cornell University, without whose advice and assistance this 
bulletin could not have been issued. 
Those interested in the subject are made up of all sorts and 
conditions of men, including not only the child with the strip of 
ground so dear to his heart, which has first brought him in touch 
with Nature’s wonderful mysteries of the development of the 
seed into the living plant, and which has engendered a love for the 
soil never forgotten; the urban dweller with his circumscribed 
garden plot, whose hours of sunshine are as few as those in the 
canyons of the mountains, and the farmer with his more ample 
space — sometimes, alas, like “the field of the slothful and the 
vineyard of the man void of understanding,” yet when properly 
managed a most potent factor in his farm economy — but also the 
one who specializes in vegetable growing on a large scale. To all 
of these whom this volume reaches with the springtime goes the 
wish on the part of the compiler, that it may be not only pro- 
ductive of seed sowing, but also assist in a more abundant harvest.
