ACKNOWLEDGMENTS 
For help most generously given during the preparation 
of this volume the author is under obligation to many per- 
sons. In the list of those who have read most of the galley 
proofs and from whom many helpful criticisms and addi- 
tional statements of fact were received are W. E. Larson, 
Principal of the County Training School of Algoma, Wis- 
consin, previously for several years Inspector of Rural 
Schools for the State of Wisconsin; J. L. Randall, now in 
charge of gardening in the Fitchburg, Massachusetts, Nor- 
mal School, formerly Director United States School Garden 
Army; W. R. Beattie, Extension Horticulturist, United 
States Department of Agriculture; Hugh Findlay, of the 
Department of Agriculture and Horticulture, Columbia 
University, New York City; and Kenneth Boynton, for- 
merly Supervisor of the Garden School for Convalescent 
Soldiers and Sailors, now acting Head Gardener in the New 
York Botanical Garden. The chapter on ‘Insects in the 
Garden” was read by F. H. Chittenden, and the chapter 
on “Diseases of Garden Plants” by W. W. Gilbert, both 
of the United States Department of Agriculture and both 
of whom contributed suggestions and ideas of the greatest 
value. Many of the uncredited photographs which so 
splendidly illustrate the processes of gardening were secured 
from W. C. McCollom, Islip, New York. 
To all the persons named above, to all those who have 
contributed illustrations as acknowledged, and to various 
. other persons not mentioned who have answered letters of 
inquiry or whose writings have been consulted, the writer 
wishes to express deep appreciation. 
It has indeed been a pleasure to write this little book.
