 resiitifcra, from the belief that the gum chewed by the natives came from this 

 source. This gum was perhaps kauri-gum. Lindlcy, in his " Vegetable 

 Kingdom," when speaking of the Jfaugrove, improves upon Forster's statement 

 thus: "It exudes a kind of green aromatic resin, which furnishes a miserable 

 food to the Ijarbarous natives of New Zealand." The source of the error may be 

 traced to Crozet's " Voyage to Tasmania " ; v. Ling-Roth's Translation p. 3G). 



Tliis IS tlie mangrove of tlie Auckland Coast. It is to be

 crowds of withered, trodden d<jwn old criminals, condemned 

 to the punishment of everlasting life. I can't help it if this

Doubtless, however, much of the evil re[)utati()n of tlie 

 mangrove forest, is due to the fact that, to its presence, has 

 long been erroneously attril)uted the prevalence of malaria in 

 tropical river estuaries. Miasmatic va.])ours were supposed to 

 arise from the pestilential mangrove swamps, and spread their
