INTRODUCTION. 



Scope of the Work. 



Various phases of educational work come within the scope of the 

 work of the Geological Survey of the State. The Survey originated 

 as a Ge< ' gical and Biological Survey of Oklahoma Territory. In 

 the regular work of members of the Survey a large amount of ma- 

 terial and information is gathered concerning the natural resources 

 of the State, 'litis information is given to the citizens of the State 

 chiefly through articles in the papers, and by the publication of 

 circulars and bulletins. 



Early in 1"12 the Geological Commission directed that a study 

 of the tree- of the State he undertaken at once. This work was 



gned to the writer. The information so far collected has been 

 secured while carrying on field work in connection with the regu- 

 lar work oi the survey. This report is only preliminary. The work 

 will be continued throughout the year along with other investiga- 

 tions, and it will be arranged to give a part of the year entirely to 

 the work. Some consideration has been given to the trees and 

 shrubs, and the condition of growth in sixty-six counties of the 

 State. A preliminary list oi the trees and shrubs was prepared and 

 typewritten copies were furnished to a number of persons over the 

 State, who were interested in gathering information concerning 

 the trees. This list has proven to be in considerable demand and 

 it is thought best to put it in more convenient form pending the 

 publication of the final report. In the preparation of this work the 

 writer has endeavored to give such general information as will make 

 this report of value to the schools of the State, and to the public in 

 general, until a more complete publication can be prepared. 



In the present report the family, genus, scientific, and common 

 names of the trees and shrubs are given, and in addition are notes 

 on the general and specific occurrence of each plant included in 

 the report. The name- of a few vines and other plants having a 

 close relation and association with the trees are given. An her- 

 barium is being prepared of all the native plants included in the 

 list. A large number oi photographs oi the trees have been taken 

 and many of these will be used in the complete publication. Any 

 additions, corrections, or suggestions will be gladly received. 



Previous Work and Publications. 



There is no person in the State who is making tree Study or 

 forestry his business. To the present time nothing ha- been pub- 

 lished which can be called a catalogue of the tree- or Other plant- of 

 ( Oklahoma. There has been very little published which will give
