could be issued for those animals which qualified and all data per- 

 taining to the cows that have produced the required amount of 

 butterfat could be given publicity. 



This would do much to increase the value of high producing 

 animals in our herds, would teach the dairymen the value of 

 keeping records and stimulate them to use modern dairy practises 

 on the cows which they already have. Improvement of dairy 

 herds would soon follow here in Hawaii just as surely as it has 

 done wherever these cow testing associations have been formed. 



Eucalyptus Plantation 



Report on the Experimental Plantation established in 1911 in 

 Nuiianu Valley, Honolulu Watershed Forest Reserve, Oahu, 

 Territory of Hazvaii, by the Division of Forestry, Board of 

 Agricidture and Forestry, in cooperation ivith the Forest 

 Service, U. S. Department of Agricidture. 



By C. S. Judd, Superintendent of Forestry. 



NATURE AND OBJECT OF PLANTATION. 



This plantation of the 18 different species of eucalyptus trees, 

 enumerated on the following list, was established in Nuuanu 

 Valley, about AV^ miles from Honolulu, Oahu, Territory of Ha- 

 waii, at a point about 1000 feet northwest of the sharp turn in 

 the road above Luakaha at an elevation of about 1000 feet above 

 sea level. The first trees were planted in June, 1911, and the 

 balance in March, 1912, all of the trees being set out 6 by 6 feet 

 apart. 



The object of this plantation, as set forth by my predecessor, 

 Prof. Ralph S. Hosmer, who instigated the experiment, was "to 

 secure data as to the habit, form, rate of growth and relative 

 value under local conditions of species of eucalyptus supposed to 

 be of economic importance, that are as yet but little known in' 

 Hawaii." 



On account of the exposure to the strong trade wind sweeping 

 down the valley, the rather excessive rainfall averaging about 175 

 inches annually, and the presence of a rank growth of Hilo grass, 

 Paspalum conjugatum, which kept the ground, except in the very 

 driest seasons, in a very boggy condition, the conditions for the 

 best growth and development were not favorable and the trees in 

 this experiment may be said to have undergone a very severe test.
