20 ADVICE FOR FOREST PLANTERS IX OKLAHOMA. 



The greatest climatic disadvantages are excessive heat and occa- 

 sional droughts. The average annual rainfall is more than 35 inches 

 and would be abundant for the growth of both forest trees and agri- 

 cultural crops if it were somewhat better distributed. The native 

 hardy species, like the oaks, have little difficulty in withstanding 

 these conditions; hence this part of the Indian Territory, though a 

 prairie country. i- potentially forest land. 



The chief planting site ;it Henry Kendall College is a semicircle 

 located directly in front of the main college building, with a radius 

 of 3*20 feet. (See fig. 3.) Hedge- and windbreak- are provided to 

 protect the athletic park, gardens, and orchards. Single lines of 

 trees along the drives and near the outer boundaries of the tract are 

 intended to add to the beauty and comfort of the situation. 



A very important part of the plantation is the nursery, occupying 

 a -trip 7~> feet wide at the east edge of the semicircle. This is to be 

 used for demonstrations to the students of fore-try and to produce a 

 supply of young trees for planting on the campus. The portion of 

 the semicircle west of the nursery is to be devoted to the growth of as 

 many hardy species as is practicable. In general, a -ingle species 

 will be -et in each row. and the trees of the whole plantation will be 

 set 1 feet apart, in row- 8 feet apart. The following species have 

 been recommended :

 windbreak- south of the garden, west of the boy-* dormitory, and 

 south of the orchard in the northwest corner of the campus, are to be 

 of Russian mulberry planted 3 feet apart in -ingle rows. The wind- 

 break- east of the garden and barnyard will be made of Mariana 

 plum and wild plum, respectively, planted 4 feet apart in -ingle 

 rows. In either of these windbreak.-, the common -our or Morello 

 cherry may be substituted, if desired. The purpose in planting the
