Valuable information in connection with the introduction of 

 spraying has also been afforded by Mr. C. French in the 

 " Destructive Insects of Victoria. "i Here he dates the first 

 appearance of the codlin moth in Victoria back for about 35 

 years. He recommends spraying with London purple and Paris 

 green, as used in America, Europe and elsewhere for the 

 destruction of the pests, the spraying to be done when the 

 fruit is just set. 



On page 53 he states further that recent experiments by 

 Prof. Riley in America, and others in Europe, have proved 

 beyond a doubt that Paris green and London purple are the 

 two best materials for spraying yet tried for the purpose. 



In Part IV. of the same work Mr. French sets out The 

 Vegetation Diseases Act in Victoria of 1896, the first orchard 

 inspectors being appointed in 1898, from which time, presum- 

 ably, spraying began to be enforced. Mr. French mentions bitter 

 pit as gazetted under the Vegetation Diseases Act in Pt. IV. ,-^ 

 and in this volume he first mentions arsenate of lead as recently 

 coming largely into use in Victoria and other Australian States, 

 with great success in the eradication of codlin moth. Some 

 insight into the increase of spraying operations in Victoria may 

 be obtained from the following extracts from the Journal of the 

 Department of Agriculture of Victoria. 



In 1902, page 428, Mr. McAlpine gives the results of success- 

 ful experiments performed in 1901 and 1902 for the elimination 

 of Black Spot by the use of Bordeaux mixture. 



In the same year Mr. Campbell, on page 290, states that the 

 value of spraying for codlin moth is now being recognised, and 

 Paris green applied to the small fruits on which the larvae are 

 crawling about no doubt poisons a number of the latter. 



In 1903 Mr. McAlpine describes further spraying experiment 

 for black spot, and on page 354 remarks that spraying for black 

 spot and other fungus diseases has now become a recognised 

 practice in the best orchards. 



In December, 1905, on page 737, Mr. J. Laing, Harcourt, 

 states: "For codlin moth spraying with one of the arsenical 

 sprays should be attended to at regular intervals." The same
