Nyassaland.

‘ We hold no brief, and are actuated by no party: we merely 
discuss the problem from the scientific standpoint, and if sentiment 
sways us towards the prevention of vandalism in the works of man

correspondent’s propositions and shows the danger existing. We do 
not presume to enter the lists on a footing with such observers as
