price by the agreement that the grantee plants thirty thousand 

 trees on the land, at the rate of three thousand a year, and at 

 the expiration of ten years the government delivers a deed to 

 the property. 



The purpose of the sale is primarily to conserve the water 

 supply, by reforesting a bare hilltop which at one time pos- 

 sessed an abundant natural herbage. 



Walter McBryde has for some time past taken an active 

 part in forestry work on Kauai and was one of the first in 

 the Islands to recognize the immense value of preserving 

 the forests of our watersheds, and to actively undertake in 

 their conversation. The rehabilitation of Kukuiolono with 

 forest trees will entail much labor, but its successful accom- 

 plishment is greatly to be desired. 



One of the features of the lava ejected by the recent vol- 

 canic outbreak in south Hawaii has been the presence of 

 numerous particles of olivin. Crystallized silica occurs in 

 many of the former lava flows of the Hawaiian Islands, and 

 generally is found in the form of the well known olivin. This 

 stone belongs to the chrysolite group of minerals and is a 

 frequent constituent of volcanic and meteoric rocks. It is 

 of some commercial value when occurring in sufficiently large 

 and good chrystals. It is knowm in France as the "peridot," 

 under wdiich name it figures in jewellers' catalogues. The 

 Hawaiian olivins are generally of very mediocre quality and 

 of insufficient value to repay collection. They are also said 

 to possess an additional disadvantage of undergoing rapid 

 deterioration. Although usually quite small, many of large 

 size have been found, notably on Hawaii. This mineral 

 possesses great hardness and may be observed in the matrix 

 even while the latter is in a semi-molten condition. The 

 minute size of the specimens thrown up by the present out- 

 break, indicates that the flow has issued from no considerable 

 depth. 



In response to numerous requests, and in view of the de- 

 veloping interest in the cultivation of vanilla, we are arranging 

 to publish in the Forester the salient features of Bulletin No. 

 21, of the U. S. Department of Agriculture, Division of Bot- 

 any, entitled "Vanilla Culture, as practiced in the Leychelles 

 Islands." The publication is by S. T. Galbraith, and is now 

 unobtainable. It contains a review of the cultivation of va- 

 nilla ?nd gives practical directions for starting a vanillery. 

 The illustrations showing the method of artificial pollination 

 are of great use. The bulletin has been loaned for reproduc- 

 tion inthe Forester by the Superintendent of Forestry.
