titles there being- much less rubber in the latex according to the 

 coagulation and preparation. The Hevea latex is coagulated 

 in various ways, but most often by acetic acid. The rubber is 

 shipped in pancakes or run through a machine giving crepe rub- 

 ber or as worm rubber, or best of all, crepe rubber is blocked 

 under pressure so that little of the surface is exposed. In Cas- 

 tilloa the rubber is creamed off after mixing with water. 



SPECIES FOR HAWAII. 



As to the variety growing here Ceara grows most luxuriantly 

 and in proper localities seems to yield extremely well. Hevea 

 grows very slowly and may not yield at all. If we can raise 

 enough Hevea to have our own seed supply, then, if it is going to 

 pay we can plant up Hevea in place of the Ceara, though we may 

 find it to our advantage not to do so. 



As to quality Hevea and Ceara are about on a par. 



ACREAGE IN RUBBER. 



There is no question of the tremendous amount of planting 

 going on — 250,000 acres in Ceylon and the Malay States, 90,000 

 acres planted in Mexico. Plantings in Borneo, Java, Samoa 

 and many South Sea Islands. Planting in Central America and 

 Africa, and in fact all over the tropical world. But on the other 

 hand we planters see that side of the question as the largest. 

 Some cry over-production ; on the other side are the manufactur- 

 ers sa3dng we never can have too much rubber. The consumption 

 is doubling every ten years and there are new uses every dav. 



PRICE OF RUBBER. 



Think of the increase of the automobile trade. Probably, 

 however, the result will be that there will eventually be a con- 

 siderable reduction in price after a few years which will multiply 

 the uses of rubber and keep up the price. If we can produce it 

 for 30 or 40 cents a pound, it will be profitable for many years 

 to come. 



RUBBER PESTS. 



Mr. L. A. Thurston now read a paper by Mr. Kotinsk}- on rub- 

 ber pests. This paper is included in this issue and forms aseperate
