Arbor Day 



Arbor Day this year will be celebrated on November 16, and. 

 as usual, there will be available at the Government Nursery for 

 planting on this day a large supply of ornamental, shade and 

 forest trees. These will be distributed free of charge in limited 

 quantities to all those who are interested in tree planting. Arbor 

 Day has usually been the occasion for improving the school 

 grounds, and it has always been a delight to see the interest that 

 school children have taken in tree planting on this day. It 

 should be borne in mind, however, that interest in this subject 

 should not cease with the mere setting of the tree in the ground. 

 The care of the tree after planting is just as important. The 

 watering of the tree in dry weather, the clearing of the weeds 

 and grass from around the base of the tree, and its protection 

 against destructive animals are all essential to* have it develop 

 into a vigorous and beautiful tree which will remain for many 

 years a permanent and attractive addition to the school grounds. 



During the past dry season we have been reminded, by the 

 scarcity of water in many parts of the Territory, of the essen- 

 tial part that the forest plays in the conservation of water, and it 

 would be fitting on the coming Arbor Day to extend the planting 

 of trees to water-producing areas which are in need of refores- 

 tation. 



Directions for obtaining trees and a list of the trees available 

 at the Government nurseries, prepared by the forest nurseryman, 

 are printed elsewhere in this issue. 



A new bulletin by Consulting Botanist J. F. Rock was distrib- 

 uted during the month by the Division of Forestry. This was 

 issued as Botanical Bulletin No. 4, on "The Ohia Lehua Trees of 

 Hawaii," in which the trees of this genus have been reclassified 

 after exhaustive study and placed in proper botanical order. The 

 bulletin is profusely illustrated and is a distinct addition to the 

 literature on Hawaiian flora. 



During the month the Division of Forestry planted 2221 na- 

 tive koa trees on watershed areas in Manoa and Makiki valleys 

 back of Honolulu, in following out the plan of reforesting all
