58 Annals Entomological Society of America [Vol. VIII, 
nets which had been used for staining mosquitos were to be 
used under buildings, a careful search was made to eliminate 
any dead, colored mosquitos which might be entangled in the 
meshes of the net; and if by any chance a hard-dried mosquito 
was found among a fresh lot, it was always discarded. In 
this way it is believed all chance errors were eliminated. 
From Feb. 8 to 21, mosquito bar nets were placed at several 
sites, with negroes again as bait, assisted at times by dogs and 
hens. During these trials 173 colored mosquitos were recovered. 
Those near the marsh do not figure in the table of recovered 
mosquitos. The following table presents the data for twenty- 
four separate nets, during six days. The Anopheles take mostly 
to men, not merely because of larger surface area, but because 
these insects prefer human beings to dogs or hens.
