Press Bulletin No. 12, Tobacco in Hawaii, (/wos an account of experi- 

 ments carried on })y the station at Haniakua, Hawaii, in oi-owing 

 tobacco. The experiments, which had been in progress for but a 

 single 3'ear, seemed to indicate the possibility of growing cigar 

 tobacco of good quality in certain regions of the islands. 



Press Bulletin No. 13, Rul)ber in Hawaii, gives compiled informa- 

 tion regarding the rubber-producing trees and vines of the world, 

 describes specimens already growing in the islands, and gives sugges- 

 tions for planting and cultivating rubber trees. 



Press Bulletin No. 14, Fuller's Rose Beetle, describes one of the 

 most injurious beetles of Hawaii, whe;-e it is known as the "Maui" or 

 "Olinda beetle." It feeds on a wide range of economic plants, and 

 remedies are suggested. 



REPORT OF THE CHEMIST. 



By E. C. Shorey. 



The ])eginning of the fiscal year 1905 saw the chemist still occupying 

 the small building serving as office, li))rary. and laboratory. In the 

 temporary laboratory fitted up in this building the soil work and 

 preparation of fodder samples, noted in the last report, was continued. 



In the case of fodder samples the method of preparation was as 

 follows: A weighed (luantity, usually 500 grams, of the green fodder 

 was chopped and air dried, weighed again, the loss on air drying being 

 recorded. The whole of the air-dried sample was then ground and 

 passed through a 0.5-millimeter sieve, and a portion stored in an air- 

 tight sample bottle. Quite a number of samples so prepared were 

 _ rendered useless for purposes of analysis by the ravages of the ciga- 

 rette beetle {Lasiodenna serricorne). In some cases the beetles made 

 their appearance three weeks after the samples were stored. This 

 preparation of fodder samples and a continuation in a small way of 

 the work on soil nitrogen was the only work done in the temporary 

 laboratory. 



NEW LABORATORY. 



The new laboratory was completed in October, and moving in and 

 fitting up took about one month. The water and gas pipes and some 

 shelving not included in the contract were put in with station labor. 

 The main room of the laboratory is 25 by 35 feet, with a small nitro- 

 gen room partitioned off from one corner. Adjoining the main 

 room are three small ones — an office, a balance room, and a dark room. 

 The main room is well supplied with worktables, sinks, and hoods. 

 There are sinks and hoods in the nitrogen room and a sink in the dark 

 room. The worktables are well lighted, and with a slight increase 

 in equipment it would be possible for three chemists to work without
