I amindebted to Dr. Tromp de Haas, for the illustration showingPara rubber at the Experiment Station, Buitenzorg, planted asstumps in January, 1904; the photograph was taken in December,1905, so that the trees were then nearly two years old. Climate in India. In some parts of India the climatic conditions are such as toallow of the cultivation of Para rubber up to 3,500 feet above sea-level, and what appear to be satisfactory rates of growth are re-ported from many parts. Extensive tracts of country are beingopened up, especially in the Travancore district, and good results areanticipated on account of the abundance of rich alluvial soil whichis reported to exist there. The accompanying illustration Series B, Plate 2, will indicate thegrowth obtainable in the Anamallai Hills, in S. India, at an eleva-tion of 3,500 feet above sea-level. In this particular instance

In South India variousspecies of rubber-yielding plants are being tried at high elevations,in conjunction with tea and coffee. The illustration, Series B,Plate 2, shows Para rubber and coffee both doing well at a highelevation, and the results of tapping on an estate in theShevaroy Hills are given in the chapter dealing with yields. It isas well to bear in mind that the elevation up to 3,500 feet in so farthat it is affected with changes of atmospheric pressure has verylittle influence on the growth of the rubber: far more important arethe questions of ranges of temperature and rainfall. Africa, West Indies, Borneo, &c. The illustrations given elsewhere will show under what con-ditions Para rubber is being grown in Ceylon and other parts of thetropical world, for in addition to alluvial flats and gentle slopes,rocky hillsides and well-drained swampy land have been proved tobe suitable
