32 INSECT PARASITES. 



it is well known that they do occasionally enter the 

 ear and nose of the fowl, duck, and gosling. 



Dr. Sharp has observed this method of transference 

 himself. In 1890 he exhibited, at the Entomological 

 Society of London, a specimen of the 0. avicularia, 

 taken at Dartford, to which there were firmly 

 adhering several specimens of a Mallophagous 

 insect. 



Prevention and Remedies. 



Just as in the prevention of Fleas, so in Lice, clean- 

 liness is one of the most powerful agents we can 

 employ. Floors, ceilings, nests, and perches should 

 be well whitewashed in the early spring, paraffin 

 beino- added as mentioned before, with soft soap to 

 make it adhere more firmly to any small lice that 

 may have wandered off the birds. This wash should 

 be sufficiently liquid so as to run into every crevice. 

 A second cleaning should also be given again in the 



autumn. 



There is nothing that keeps birds free from lice so 

 well as Dust-Baths ; these are natural remedies for 

 the lice, and fowls should never be kept without 

 them. In every run or house there should be placed 

 a o-ood-sized square box containing some powder in 

 which the bird can dust itself. The writer has, after 

 numerous experiments, found that ordinary road dust, 

 in which a few handfuls of sulphur and lime are mixed, 

 is as successful as anything. Sand mixed with a 

 small quantity of creosote will also keep the birds
