PEEFACE 



The title, Trees in Winter, might seem to one unacquainted with 

 the subject to confine the usefulness of this book to the months De- 

 cember, January and February. Winter, as we shall use the term, 

 is not defined by the human calendar. It is that period when the 

 tree is in its resting condition, and may be considered to extend 

 from the shedding of the leaves in the fall to the bursting of buds 

 in the spring. The period is different for different trees and in dif- 

 ferent localities, but in the northeastern United States it may be- 

 gin as early as the latter part of September, with such forms as 

 the Butternut, and may extend even into the middle of May with 

 the Catalpa. The title would further emphasize the general rule 

 brought out in Part I that the buying, planting, and care of trees 

 should take place only in their dormant condition. Such excep- 

 tional treatment as spraying for leaf diseases will be discussed 

 for the sake of completeness but it still remains true that a tree 

 generally would better be left untouched during its growing season. 

 The material in Part II, first appeared in pamphlet form as a bul- 

 letin of the Storrs Agricultural Experiment Station. The demand 

 for the bulletin, especially for use in the schools, has proven so 

 great throughout the state that it seems desirable to publish the 

 information in book form and thus render it more widely avail- 

 able than could be the case in a state publication of necessarily lim- 

 ited distribution. 



Part I, on the planting and care of trees, has been added in car- 

 rying out the suggestion of the publishers and many of our corre- 

 spondents who have thought that such an introductory part would 

 broaden the usefulness of the book, especially among those who 

 possess trees of their own. The section is written primarily for 

 the individual and his home grounds rather than for a municipal 

 street planting commission. The viewpoint, therefore, will be 

 more that of the country and of the home than that of the city. 

 Xo especial originality is claimed for the material in this part, a 

 considerable number of publications including government bulle- 

 tins have been consulted in its preparation. If the arrangement 

 of the subject matter renders needed information easily obtain- 

 able, it will have served its purpose.
