FOREWORD TO VOLUME XI 
Mr. Burbank begins this, his eleventh volume, 
with a chapter, which, to the majority of readers, 
must be novel, describing, as it does, the business 
side of raising nut crops. He continues throughout 
the range of profitable nuts, discussing the paper- 
shell and other walnuts, the almond, the chestnut, 
the hickory and a miscellaneous company of other 
nuts—with many definite suggestions for improve- 
ment. 
He tells, also, in this volume, the method 
employed to produce in twelve years a walnut 
tree such as nature takes seventy years to produce; 
he gives his ideas on how reforestration may be 
accomplished profitably; he describes each class 
of tree which yields us gums and syrups, and con- 
cludes with a practical chapter on trees and shrubs 
for shade and ornamentation, together with a 
number of new tree experiments which offer 
encouragement.
