suggests that the same application be made in a trench around 

 the base of the tree. 



'' From New Zealand comes the statement * that soot, buried 

 6 or 7 inches deep under infested apple trees, rids them of this 

 same woolly-aphis, the ' American blight ' as they call it. 



"In Miss Ormerod's report a number of apple pests are 

 treated, none of which are of particular interest to Amer- 

 ican horticulturists save the bud-moth {^Tffietocera ocell- 

 ina^ for which no satisfactory remedy is suggested. This 

 is interesting, because Harvey stated at the meeting of the 

 economic entomologists in November that this insect had 

 attacked the terminal buds of the blackberry in Maine, an 

 entirely new habit for this species. 



'' Harvey has also studied the ' railroad worm ' {^Trypeta po- 

 monella) in Maine. His results are not yet published, but we 

 understand that gathering and destroying the infested fruit is 

 recommended as the most practical remed}^ 



''Gillette gives a brief account of the apple curculio f 

 (^Anthonomus quadri-gibbns^ which has been seriously injurious in 

 some parts of Iowa. Spraying, jarring and the destruction of 

 fallen fruit are all recommended for this insect. 



"A second edition of Miss Ormerod's valuable 'Manual of 

 Injurious Insects and Methods of Prevention,' has been issued 

 in England, during the year. It contains much of interest to 

 horticulturists everywhere. Of present interest is the article 

 on the 'wood leopard moth' {Zeiizera cescali). This pest 

 has been quite recently imported into this countr}^, and is now 

 beginning to spread, radiating in every direction from the 

 vicinity of Jersey City. In Europe it is destructive to pear ; 

 in this country it has, thus far, been found only on elm. J 



" Riley § has treated the 6-spotted mite of the orange {Tet- 

 ra?iychus 6-macidatus), and finds it easil}^ controlled by the 

 various soap and kerosene preparations, by sulphur and even 

 clear water. Clean culture is also an effective method of pre- 

 venting injury. He also calls attention || to the fact that some 

 of the scales infesting oranges in Florida have made their 

 apperance in California, and repeats his suggestion that a quar- 

 antine be established in these states against infested plants
