The eucalyptus tree is efficacious in preventing malaria. The cause is supposed to be that its thirsty roots drain the soil for many yards around, and that its large leaves exhale an aromatic oil and intercept the malarious germs. An incident shows its efficacy: An officer in India whose troops were often attacked by sickness removed their huts to a place where several large trees grew between them and the swamp, and from that time until the trees were cut down the troops enjoyed excellent health; afterwards sickness reappeared. It appears to be only in the case of zymotic diseases that the trees operate as a preventative, but that is of no slight value in many districts.
