H)8 THE CULTURE OF THE CHRYSANTHEMUM. 



have had to replant 16,000 'mums upon one acre of such 

 land. Starlings catch thousands of " Leather Jackets " if 

 the insects venture near the surface, but when the flatter 

 attack newly set plants, there seems but one way to deal 

 with them viz., to search round the plant and, having 

 found them, kill them. I have seen sufficient to fill halt 

 a gallon caught day after day. Vaporite can be put into 

 the ground to destroy them without killing the plant, or 

 syringing with the smallest possible quantity of paraffin 

 in the water is a good method to keep them at bay. 

 It is only while in the grub state that they are so 

 destructive ; they bite small plants in two, and eat the rind 

 off harder plants.

The Frog Fly. 



Everyone has noticed upon various flowers little patches 

 of frothy matter called "cuckoo spittle." This is caused 

 by a tender little insect which by sucking the plant buries 

 itself in this froth, which protects it from heat and other 

 inimical effects until it is fully grown, when it changes to 

 a pupa and finally to a fly the " frog fly " or " jumper." 

 These flies are sometimes credited with causing the mis- 

 chief which is done by the green bug, but after they have 

 left the frothy substance they do not pierce the plant. At 

 the same time, it is well to destroy all that can be caught.
