 actual construction works. 



Short descriptions of the woods of the various species under 

 test are given with the investigations made in each case. A num- 

 ber of tables show in figfures the actual results obtained. 



The Forests of the Hazvaiian Islands; Win. L. Hall, U. S. 

 Bureau of Forestry. 



In Hawaii the best timber tree is the Koa, a highly prized 

 cabinet wood, with a color varying through rich shades of red and 

 brown and with a fine and distinct grain, but the forests are of as 

 much importance on account of their influence on other industries 

 as for their direct products. Those business interests which, like 

 rice and sugar production, are largely dependent upon the moun- 

 tains for a supply of irrigation water, naturally in most cases 

 strongly favor preserving the mountain forests. So strong has 

 been the interest of some of the sugar companies in the preser- 

 vation of the forests that they of their own account have maintain- 

 ed large forest reserves above their plantations. Since 1882, the 

 Government has undertaken work in the planting of denuded 

 tracts. 



Chestnut in Southern Maryland; Raphael Zon, United 

 States Bureau of Forestry. 



Chestnut occurs in Canada only in Western Ontario, so that 

 this bulletin is somewhat narrowed in interest for the Dom- 

 inion. In Maryland the chestnut has been saved from extinction 

 largely from its sprouting capacity. The conditions for the repro- 

 duction of chestnut from seed arc unfavorable, owing to the de- 

 mand for the nuts. The capacity to produce sprouts from the 

 stump or from the roots is possessed almost exclusively by hard- 

 woods, and sprouting fmm the stump or sttx)l, generally known as 

 the "coppice" method of management, is that by which the chest- 

 nut is generally reproduced. Stumps one foot high show the best 

 results, and winter or early sjiring is probably the best time for 

 cutting. Coppice chestnut furnishes better timber for working 

 than chestnut from the seed : it is heavier, less spongy, and
