Mr. Play-fair, the English consul at Algiers, has sent a report to his government on the improvements brought about by the planting of the Eucalyptus. He very properly condemns the nonsense that has appeared in relation to the Eucalyptus as injuring the real value of the tree. Many hundred thousand have been planted in Algeria since 1870. They were planted in marshy ground. The immense growth calls for an increased supply of moisture, and in this way marshy ground is made dry, and with this root-draining mosquitoes as well as fevers disappear. It is by acting as a drainer of the soil that its merit as a purifier of the atmosphere exists; and in this respect Mr. Playfair considers it has been a 'great boon to that fever-stricken country. He also adds that the tree is not so tender as some people think, but can be made to thrive in any part of the world where orange trees will live through the winter.
