fumigation with tobacco stems kills the aphis." (Popular Gardening,

We have omitted from the above the references to prevention of

 of the tobacco dust. 



A Lime "Wash for Bark-lice. 

 The following application has been recommended for the destruc- 

 tion and removal of scale insects infesting fruit trees. The materials 

 named are certainly sufficiently powerful to accomplish the purpose, 

 and the omission of one or two of the number would not, it would 

 seem, impair the efficacy of the wash. It is as follows: 



Slake stone lime, as for whitewash, and to two-thirds of a bucket- 

 ful add one pint of gas-tar, one pound of whale-oil soap dissolved in 

 hot water, one pound of common soft soap, one pound of potash or one 

 pint of strong lye from wood ashes, and also clay or loam enough to 

 make the wash of proper thickness to be applied with a whitewash 

 brush. 



It is also claimed for the above that it is an effectual remedy and 

 preventive of the peach-tree borer, if the earth be removed from the 

 collar of the tree and thoroughly applied about the base; also, that if 

 the trunks of apple trees are coated with it, it will prevent the 

 operation of the striped apple-tree borer.
