(Cryptomeria japonica) and Monterey cypress may be tried 

 for underplanting on elevations above 800 feet, while at the 

 lower elevations one of the tolerant eucalypts like swamp ma- 

 hogany may be tried. If the spacing or the size of the originally 

 planted trees will interfere with the ready growth of additional 

 trees, it may be necessary to cut off the present forest as soon as 

 it is large enough to be utilized, and to plant additional trees 

 between the stumps so that the sprouts of the stumps and the 

 new trees planted will form a fully-stocked stand. 



Where the present forest consists of inferior species or poor- 

 ly-developed trees, it is desirable to convert the_entire stand into- 

 a more valuable forest with the least loss of time in order to- 

 utilize the land to the best advantage. It would be poor policy, 

 however, to cut off the entire forest at once until it is ascertain- 

 ed that more valuable trees can be made to grow there. Fur- 

 thermore, the forest already growing can be made to serve as a 

 windbreak for the new plantation. Accordingly, a belt of the 

 old forest, 100 to 200 yards in width, should be left on the wind- 

 ward side, and behind this belt a few acres at a time should be 

 cut and replanted with the more desirable trees until the entire 

 stand back of the windbreak is restocked. Except in places 

 where there is little danger from windfall it would probably be 

 best to allow the strip of old forest to grow indefinitely and act 

 as a windbreak or shelter belt for the more valuable stand. 



ROADSIDE PLANTING OF EUCALYPTUS. 



Many thousands of trees are planted along the roads in Ha- 

 waii, as well as along fence lines and lot boundaries, and such 

 planting can be made an important source of firewood and fence 

 posts, if carefully managed. The eucalypts, as has already been 

 stated, are excellent shade trees and make desirable roadside 

 trees, especially the blue, red, and lemon-scented gums, the mess- 

 mate (E. amygdalina), and the swamp mahogany. Complaints 

 are sometimes heard that roadside planting keeps the roads in 

 poor condition because it does not allow the surface to dry 

 readily. If proper care is used in setting out the trees, this diffi- 

 culty can be obviated to a large extent. Planting on the wind- 

 ward side of the road should be either wide spaced or entirely 

 omitted so that the wind may have free access to the road. On 

 both sides of the road the trees should be spaced in such a way 

 as to allow the sunlight to strike the road at some time during 

 the day, successive parts of the road being in turn kept in shade. 

 If these simple precautions are taken, there should not be diffi-
