AMMONIA FOR GEARA. 



In some districts 5% Ammonia is run from 

 drip tins down the tapping cuts made on Ceara 

 trees to induoe the flow of latex and prevent it 

 from coagulating in the cuts and tins. tVhon 

 Ammonia is imported on to the estate in large 

 quantities for this purpose. Commercial Am- 

 monia, which contains about 56% of Ammonia, 

 should be bought, and not what the chemists 

 call Liquor Ammonia Fort with a specific gra- 

 vity of -880. The latter is very strong and° in 

 this climate dangerous to handle, and in open- 

 ing say, a 5 gallon drum a bad accident can 

 easily occur. The Commercial Ammonia in 5 

 gallon drums, equal to about 501b, costs in Ban- 

 galore 8£ annas a pound, and it can bo easily and 

 safely diluted to the desired strength —Ru-

"ARTIFICIAL CAMPHOR." 



E. Darmois (' Comptos Rend.,' 1910, 150, p. 

 925) states that he has succeeded in preparing 

 artificial camphor with an optical activity nearly 

 equal to that of the natural product by working 

 at relatively low temperatures. Oil of turDeu- 

 tine, freed from the portion distilling above 

 165 w C, was converted into pineno hydrobro- 

 mido, from which borneol was obtained by 

 means of its magnesium derivative. Any dib- 

 ornyl formed was separated by distilling the 

 borneol with steam, and the borneol was purified 



by re-crystalhsation from petroleum spirit On 

 oxidation the borneol from Aleppo pine gave a 

 camphor with rotatory power of [a^J- plus 49° 

 [natural camphor, [a]J= plus 57°]. French oil 

 of turpentine yielded a camphor with an optical 

 rotation of [a]j= -45°. A lower temperature 

 for working may possibly givo a product 

 identical with natural camphor. -Chemist and 

 Druggist, Oct. 1. 



RUBBER AND THE DEVELOPMENT 

 OF THE CONGO STATE. 



H.M Consul at Boma (Mr H G Mackie) has 

 forwarded the following particulars relative to 

 the development of the Congo State :— Rubber 

 which constitutes roughly three-fifths of the total 

 exports from the Congo, would seem to offer a 

 fairly sound basis for the creation of an industry 

 conducted on modern and scientific lines. Ac- 

 cording to an opinion recently pronounced by 

 an expert, the climate and soil are satisfactory 

 but the wrong species of plants have been 

 selected tor cultivation. 



Although of late years the oxports of rubber 

 have decreased, it will bo observed from the 

 following table that the volume of the rubber 

 trate is still substantial, and compares favourably 

 with the exports of rubber from Angola : —
