periments. Tlie following report therefore sets forth only the 

 condition of the trees as they are today. 



In visiting these plots of trees, which are found on the ex- 

 posed slopes of Haleakala, Maui, between the elevations of 67O0 

 and 9000 feet above sea level, I was impressed with the unfavor- 

 able conditions for tree growth. The soil consists of freshly 

 decomposed volcanic rock, is thin, and is subject to a great deal 

 of wash from the mountain during stormy seasons, and the native 

 vegetation found there consists of only stunted trees and shrubs 

 indicating an adverse exposure. The conditions, therefore, pre- 

 sent a severe test of the possibility of growini;' temperate zon? 

 trees at this situation and it is to be wondered that the results 

 have been as good as they are. 



The following tables show the success that has resulted front 

 the planting of these introduced trees:

Plot IV. Elevation 9000 feet. Yx mile North of Kilohana. 



This plot was not visited since the local ranchman told me that 

 none of the trees planted on it were alive. 



In analyzing the above results it should be borne in mind that 

 Plot I possesses conditions more favorable for tree growth on 

 account of better soil and more moisture. It is not surprising, 

 therefore, that the best results are found on this plot. The other
