PESTS AND DISEASES. 159 



soon find them, and be killed. (3) Carefully watch the 

 spot where a mole has recently been at work. If he is 

 still at work you will see the soil heave up, and wherever 

 this occurs stamp the ground heavily with the foot, open 

 the run, and the mole will be found, when dispatch him. 



Leather Jacket Grub. Another soil pest, with a 

 dark-coloured body, no legs, and a truncated tail. It is 

 the larva of the Daddy Long Legs, or Crane Fly, and when 

 fully grown measures about an inch in length. It has a 

 tough skin, hence its name. The grubs feed on bulbs, 

 tubers, and roots of plants, and in some seasons do an 

 immense amount of misclTief. The remedies are pre- 

 cisely the same as advised for the wireworm. 



Weevils. The grubs of several species of Weevils are 

 very partial to the corms of cyclamen, both indoors and 

 out. They are short, fat, white, legless grubs, and easily 

 detected in the soil. 



REMEDIES. If cyclamen become unhealthy, the base of 

 the corms should be examined for the presence of these 

 grubs, and the latter promptly removed. To guard against 

 the presence of the grubs in the compost by the way, 

 they are introduced in the egg or young state with the 

 leaf-mould the compost should be spread out thinly and 

 sprinkled with sufficient boiling water to moisten it. If 

 this be done a day or so before using, all insect life will 

 be destroyed, and no harm done to the compost. 



Red Spider. An almost invisible mite with a pale 

 red body, which lives in colonies under a fine web on the 

 surface of the foliage. It is more prevalent in heated 

 structures than in the open air. The mite pierces the 

 epidermis of the leaf, and sucks out the sap, causing the 

 portion of leaf attacked to assume a pale colour. 



REMEDIES. As a rule the Red Spider flourishes chiefly 

 in hot, dry atmospheres, a damp atmosphere not 'being
