72 THE WOMBAT. 



green. Many of the insect pests introduced in one way or 

 another are rapidly becoming a menace. The codlin moth 

 increases despite all precautions taken to keep it in check. 

 The scale, woolly aphis, pear slug are all much in evidence ; 

 then we have an insect that is, as far as I am aware, still 

 unknown in Victoria, the " current clear wing," a member of 

 that small family that has all the appearance of a fly, but is a 

 true day-flying moth. 



The larvae attack the currant bushes (the red currant in 

 particular), boring its way up through the pith of the branches, 

 often killing outright. An unscientific desultory description 

 of species could be prolonged ad nauseam, but I trust that 

 from among the few notes I have written, you may be able to 

 glean something that will prove of interest. 



Yours, &c,

The April meeting of the Gordon College Science Club 

 included a lecture-demonstration by Mr. Matsen, of the 

 Ballarat School of Mines, the subject being "The Recovery of 

 Gold bythe Cyanide Process." The lecturer introduced several 

 experiments to show the methods adopted, and the results 

 attending this important process in connection with the 

 mining industry of Victoria and elsewhere. The saving 

 attributable to this new departure has been the means of 

 opening up new ground as well as drawing attention to many 

 abandoned districts, and the treatment of tailings and other 

 waste as formerly regarded, opens up fresh fields for industry 

 and experiment. 



It was decided to hold a Conversazione in connection 

 with the annual meeting of the Club in July ; the Vice-presi- 

 dent and the Secretary were appointed to carry out arrange- 

 ments. 



This sub-committee has already received encouraging 

 support for what promises to be a thoroughly instructive 

 entertainment.
