Mr H. N. Whitehead announces in another column that he has just started as a photographer in this town, in the premises between the Bank of New Zealand and the Red House, in Main-street.

Mr Whitehead makes a specialty of family groups, and undertakes to take his camera to any part of the district free of charge.
