. (H ,— A fungus that choked Oalifornian I thistle has made its appearance in the 1 Totara district and elsewhere (says the Oamoru " Mail.") It attacks the under side of the leaf in the form of a brown dust, and multiplies rapidly until the whole plant is covered. The leaves then turn yellow, and the thistle withers. Investigations among crops and pastures of ail kinds in which the Oalifornian thistle is found show that It attacks no other form of vegetation, not even closely allied thistles. Search has been made in wheat, oats, rye and pasture fields in whioh the Galifornian pest is plentiful, but none of the crops were even tainted by the fungua- The fungus may only be a produot of lush seasons such as the present, but if it can be proved to be inimical to Californian thistles only it; will be worthy of cultivation. A specimen has been sent to the Agricultural Department at Wellington.
