The English sparrow as an agent in the dissemination of chicken and 

 bird mites, II. E. Ewing {Aulc, 28 {1911), Xo. 3, pp. 335-^J,0, figs. 2).— On the 

 basis of observations made in Illinois, the author concludes that the English 

 sparrow frequently harbors and is the host of the chicken mite, Dermanyssus 

 gaUince. Sparrows become repeatedly inoculated with these mites because of 

 their habit of lining their nests with poultry feathers, and sparrow nests, when 

 built in the vicinity of chicken roosts, upon becoming deserted may leave 

 hundreds or thousands of lice to infest new poultry houses, even at considerable 

 distances. The English sparrow likewise harbors and is the host of the bird 

 mite, D. avium.

 several varieties of wheat in 1910 show that their susceptibility to the attack 

 of larvae of the oscinid fly Chlorops twniopns stands in inverse ratio to the

 ternal wall of the epidermal cells.
