A list of trees and other ornamental plants was selected and 

 planted at the Experiment Station dry-farm, Cochise, Arizona, the 

 altitude of which is about 4000 feet. Another list was made for 

 planting at the Tempe Date Orchard, Tenipe, Arizona. The plants 

 for the date palm orchard were selected with reference to alkali 

 resistant qualities. 



STUDIES OF GRASSES AND GRASS LIKE PLANTS 

 The writer gave most of the summer season of 1918 to field 

 studies of our native grasses and other forage plants of the central 

 and northern parts of the State, with a view to secure as much prac- 

 tical information as possible relative to the abundance, distribution, 

 life history, and grazing value of these plants. A part of the fall 

 season was spent in a similar study of the forage plants on the bet- 

 ter class of ranges in southern Arizona. This season was peculiarly 

 interesting, since in many localities on account of the shortage of 

 grass, stock were subsisting largely on browse. 



During the early months of the school year, one-half of the 

 writer's time was taken ud with instruction work, including classes 

 in botany in the University and in physiology and hygiene in the 

 S. A. T. C. Following the abrupt close of the S. A. T. C. work with 

 the signing of the armistice, the writer began a study of the plants 

 of the Juncaceae or Bog-rush family and of the Cyperaceae or Sedge 

 family, both families of which are fairly well represented in oui 

 State. This latter was completed with the exception of the genus 

 Carex, the plant collections of Arizona of which are too incomplete 

 to make possible a satisfactory study. Although Bog-rushes and 

 Sedges are not grasses, they resemble grasses and in their growth 

 are usually associated with grasses, and besides they are of eco-
