On some of the plots the trees were mere spindling whips, 

 hardly erect, and often sprawling over the tall grass. In others, 

 where protection was afforded by small gulches, the growth was 

 excellent and trees up to 8 inches in diameter and 38 feet in 

 height were found. All varying degrees of growth between these 

 two extremes were found. The majority of the trees had flowered 

 and were found to be in fruit. 



RESULTS. 



From the foregoing table it will be seen that the best yield of 

 wood was given by the Blackbutt, Eucalyptus pilularis, amount- 

 ing to the rate of 4.51 cords per acre. This yield), wh^le much 

 better than that of any of the other plots in this plantation, on 

 account of the adverse conditions mentioned above, is small and 

 quite poor as compared with the yield of the Blue gum. Euca- 

 lyptus globulus, at Makawao, Maui, T. H., which, according to 

 Margolin, as set forth on page 34 of Bulletin No. 1 of the Divis- 

 ion of Forestry of this Board, "Eucalyptus Culture in Hawaii," 

 at the age of five years ran as high as 15.1 cords per acre at an 

 elevation of 4500 feet and 17.4 cords per acre at an elevation of 

 4200 feet but with a spacing of 12x18 feet and 12x15 'feet, 

 respectively. 



For results to be expected, however, from the planting of trees 

 of these species under conditions similar to this plantation, the 

 data given in the foregoing table may be used as criteria. 



NOTES ON PROMISING SPECIES. 



The following notes, taken from standard works, on the eight 

 species in this plantation yielding one cord per acre or more at 

 the end of the first five years of growth, in the order of) greatest 

 yield, are presented for the information of those who wish to pur- 

 sue the subject further. 



1. BLACKBUTT. E. pilularis. One of the largest euca- 

 lyptus, which becomes a tree 100 to 150 feet, rarely 300 feet high 

 and 3 to 5, rarely 12 to 15 ;feet in diamieter. The wood is pale 

 colored, strong and durable and one of the best for all around 

 timber. The tree prefers a damp climate and moist, rich soil. It 

 makes a rapid growth and is one of the best natural ^sprouters 

 after the tree is cut. 



2. TUART. E. gomphocephala. A small tree not exceed- 

 ing 120 feet in height, yielding a wood which is heavy, hard and 

 strong, very sound and possessing few or no defects. In fact, it 

 is one of the strongest timbers in the world. It is used in ship- 

 building and for bridge supports where great strength is re- 

 quired. 



3. YELLOW STRINGY-BARK. E. muclleriana. A com- 

 paratively small tree, up to 70 feet in height, concerning which 

 little is known. It has a yellow inner bark and a yellow stain
