PREPARATION OF BULLETINS 



The larger part of the writer's time in Experiment Station 

 work was spent in the preparation of a bulletin on the grasses 

 of Arizona. A small amount of work remains to be done on this 

 publication. Additional study has been made on the poison 

 plants of our grazing ranges. This applies in particular to the 

 loco weeds, larkspurs, death camas, and the whorled milkweed. 



A bulletin on the cultivated ornamental shrubs of Arizona 

 is in process of completion. This treats of about one hundred 

 and twenty-five species and varieties of deciduous and ever- 

 green shrubs and includes a brief description of each one, 

 together with a discussion of the soil, temperature, altitude, 

 and cultural conditions best suited for its successful growth. 

 This work is being done in collaboration with Miss Ethel Pope, 

 an advanced student who has made a careful study of our 

 ornamental plants. It is planned to follow this publication 

 with a similar study of our ornamental trees and vines. The 

 work in ornamental plants has developed to its present impor- 

 tance through studies in plant introduction and ornamentation 

 both in the Experiment Station and the Department of Biology 

 in the University.
