 and eggs, under-side, magnified; d, male scale^ magnified 



one quart of soft soap, or one-fourth of a pound of 

 hard soap, in two quarts of boiling water. Then in 

 i\Iay or June, soon after the young lice have hatched, 

 spray with kerosene emulsion. When the lice are 

 young they are very readily destroyed by this sub- 

 stance. The lime, salt and sulphur wash appears to 

 be effective also against this pest.
