62 GARDENING 



When peas are affected, Scotch snuff should be 

 dusted over whilst the dew is still on them. 



Cherry trees attacked by the Black Aphis, 

 which is a glutinous insect, should have the wood 

 of the tree as well as the wall they are growing on 

 washed yearly in the rest season with soft soap and 

 water, six ounces to a gallon, adding plenty of soot, 

 lime, and sulphur. When the young shoots are 

 attacked in the summer each shoot should be 

 dipped in a basin of tobacco water just before 

 they are trained 



Ladybirds should be encouraged, as they are 

 great enemies to caterpillars. Aphis, and especially 

 to American blight 



There is a machine called Curtis's Lime Duster, 

 by which repeated applications of quicklime can be 

 syringed over apples, pears, and plums, and the 

 pests destroyed. 



CATERPILLARS, TO DESTROY 



Hang pieces of woollen rag on every tree and 

 bush ; the caterpillars will congregate on them and 

 are easily caught. 



Caterpillars on Bush Fruits.— The best plan is 

 to remove the soil in the autumn from under the 

 bushes to a depth of three inches and replace with 

 fresh soil. The gooseberry saw-fly grub buries itself 

 in the ground and becomes a chrysalis, from which 

 in the spring sawflies emerge and fly into the bushes 

 and lay their eggs. The earth containing the 

 chrysalides should be burnt, as nothing else will 

 eradicate them.
