 all stages the foliage of such fruit as peach, apricot, nectarine and 

 plum, with great rapidity, and may occasion some harm when 

 present in numbers, especially to peach and nectarine.

WOODLICE. 



(Onucidw.} 



When peaches, apricots and nectarines are just ripening, both 

 out of doors and indoors, woodlice frequently attack them. The 

 commonest forms seem to be Oniscvs ascclhis L., and Armadillidium 

 nilijni'i', Lat. 



Woodlice are best trapped by placing scooped-out oranges or pota- 

 toes near the trees, or by filling pots with damp moss or fresh horse 

 manure. Fumigation with hydrocyanic acid gas has also been found 

 to kill them under glass. They love moisture and decaying wood, 

 and are usually worst in old glass-houses.
