Nevertheless public opinion waq still in favour of Eucalyptui- 

 planting, and forest and other officers were practically compelled 

 to devote money to it which might have been more profitably 

 employed. 



Mr. Gamble wrote \ Progress Report of Forest Ad)am., Northern 

 Circle, Madras, 1888-9] :— 



" The Conservator has no faith in the endeavour to acclimatize 

 the various species of Eucalyptus in the Indian plains. Doubt- 

 less, and as these trials show, a few plants can be reared if treated 

 very carefully, garden-fashion, and at some expense, but that is 

 not what the Forest Department aims at. What we require are 

 trees that can be grown easily and cheaply and on poor soil (for 

 we have very little good soil indeed and what there is is mostly 

 already covered with fine indigenous timbers of far greater value 

 than those of the Eucalypti) in dry and rocky places, and it is a 

 pity to waste money and time on such experiments when they 

 might be applied so much more advantageously to works which 

 we know are likely to succeed and pay, directly or indirectly " 

 (p. 38). 



Mr. Cameron, Superintendent of the Government Botanical 

 Gardens, Bangalore, reported to the same effect in 1890. He 

 thought, however, that E. citriodora might take the place of E. 

 Globulus in combating malaria. 



*' The blue gum experiments have proved conclusively that this 

 tree is not adapted to the plains of India. At Bangalore it attains 

 a height of 15 to 20 ft. and then dies out. We have been much 

 more successful with the species saligna, rostrata, marginata, 

 and citriodora, all of which are established in the gardens and 

 furnish seeds for local use and general distribution. Numerous 

 species of Eucalypti have been tried at intervals, but excepting 

 those mentioned above, the genus is better adapted to the hills 

 than the maidan. The success attained at Ootacamund is encou- 

 raging and indicates that E. Globulus, as well as other species, 

 will succeed in the higher altitudes of the Bababudan hills, 

 should their acclimatisation be desired at any time. Fast growing 

 trees of the class are important as a possible source of fuel for 

 railways and mills. E. citriodora is a desirable tree to plant in 

 the vicinity of swamps, or in villages that are infested by malarial 

 fever, the fragrance arising from its foliage and bark being a 

 powerful deodoriser." 



We owe to Crudeli and Klebs the abandonment of the old 

 theory of an "organic" or "paludine miasma." For this they 

 substituted that of an organism which established itself in the 

 blood of malarious patients. 



The following interesting account of the position in 1894 la 

 reproduced from the United States Consular Reports for September 

 of that year. It, at any rate, gave the final coup de grace to the 

 value of blue gum. 



" Before considering the hygienic effects of Eucalyptus planta- 

 tions with reference to malaria, it may not be irrelevant to present 

 the views of the distinguished Italian professor, Tommaso Crudeli, 

 now senator of the Kingdom, on malaria. He has made exhaus- 

 tive investigations as to the origin of the scourge, and was the
