126 DESTRUCTIVE INSECTS OF VICTORIA: 



11. Hellebore Poavder (poisoxous). — Largely in use 

 against many insects, as pear-slug, turnip-fly, 6cc. Might 

 be tried against Rutlierglen bug-pest, thrips, &c. — C. F. 



12. Kersoene.— Seemingly the most valuable of all 

 remedies, when properly applied. Almost the only 

 substance which will certainly kill the eggs without 

 destroying the plant. — Hubbard. An excellent mixture 

 if milk can be obtained cheap. — Rileij^ Hubbard., Corn- 

 stock. Sour milk for making the emulsion is as useful 

 as fresh. — Maskell. Mixed with castor-oil, linseed-oil, and 

 whale oil, may be used in the proportion of one part 

 kerosene to three or four of oil, and this has been found 

 to be very eflicacious for apple and other fruit trees 

 attacked by apple-scale {Mijtilaspis pomoru?n), but the 

 mixture must not be laid on too thick. Thinly brushed 

 all over trunk and branches at dead of winter, it has 

 been found quite successful in destroying both insects and 

 eggs, without injury to the trees. — Maskell, Personal 

 Experiments. Also used in the bush to prevent ants 

 crawling up legs of meat-safes, &c. — C. F. In America 

 calico saturated with kerosene, and stretched across bars or 

 upright frames, has been used very succesfully in destroy- 

 ing locusts whilst on the wing. — American reports. 



13. Lime. — Slaked lime, if dusted on the foliage of pear 

 trees affected with the pear slug {Selandria), is a very 

 effectual remedy, and unslaked lime, as a preventative and 

 destroyer of garden snails, slugs, and wood-lice, has few 

 equals for general efficacy. — C. F. 



14. Gas Lime. — Has been used very successfully on soil 

 affected by aphis, plant bugs, &c. ; also useful against 

 the black slug, snails, &c. — C. F. 



15. London Purple (poisonous). — According to Pro- 

 fessor Eiley and other entomologists of note, both in America 

 and elsewhere, this is the best of all remedies against the 

 codlin moth. For fuller particulars see Codlin Moth, 

 page 51. — C. F. 



16. Lye. — Sometimes spoken highly of in America, but 

 not in use here, and according to reports it is inferior to 

 kerosene in killing power, and far more injurious to trees
