Oviposition of mosquito Culex quinquefasciatus Say.--G. H. Bradley, 
Orlando, Fla., submits records which show "that of the substances tried, 
water containing manure is most attractive to ovipositing females of this 
mosquito.- During November, of 1,349 egg boats laid in our largest test, 
178, or 13.2 per cent, were laid on water containing hay infusion; 304, 
or 22.5 per cent, were laid on water containing rotting soy beans; 519, 
or 23.6 per cent, were laid on water containing commercial soy sauce; 38, 
or 2.82 rer cent, were laid on clear water; and 510, or 357.9 per cent, 
were laid on water containing manure.” 
Mosquito control at Portland, Oreg.--H. H. Stage, Portland, Oreg., 
reports that "In cooperation with the City Park Bureau and the Civic Emer— 
gency Committee, the Mosquito Control Committee of the Portland Chamber 
of Commerce benefited in their control program when 40 acres of willow 
flat were cleared of dense brush. * * * the clearing of this dense jungle 
growth directly influenced the numbers of larvae hatching in the flooded 
areas, besides making the areas more accessible for oiling. It is in this 
area that we have captured Aedes vexans Meig. latest in the season, from 
80 to 112 days after emergence." 
Sulphur dips made more effective against goat lice.--0. G. Babcock, 
Sonora, Tex., reports that "the efficiency of the sulphur dips has been 
greatly increased, in fact doubled, by the addition of linseed oil soap 
and scdium phosphate. It is also shown that still better results are 
obtained by using the wettable sulphurs in combination with the linseed 
oil soad and sodium phosphate tribasic. Formerly five pounds of sulphur 
was considered the minimum quantity to use to cbtain a kill, but by the 
addition of the above chemicals, 2 pounds of either the pure wettable 
sulphur or flotation sulphur dust is the minimum quantity per 100 gallons 
of water." 
Deer show no ill effects of arsenic treatment for ticks.——"During 
the last two months," reports H. 0. Schroeder, Brownsville, Tex., "I had 
an Opportunity to examine a herd of 25 deer at frequent intervals. These 
deer were for a time staked out over areas accessible to cattle heavily 
infested with fever ticks. Ticks became quite numerous on some of the 
adult deer, the Australian variety far outnumbered Boophilus annulatus 
say proper, the two forms appearing in about the same ratio as on the 
cattle. * * * The deer were freed from ticks in the regular arsenical 
bath under the supervision of a Bureau of Animal Industry inspector, as 
prescribed by the Bureau of Animal Industry for cattle. The deer suffered 
no apparent lasting ill effects from contact with the arsenic. This is 
of interest because this State is considering importation of deer from 
Mexico for breeding purposes and experiences of private individuals seemed 
to indicate that deer were too susceptible to arsenic poisoning to be 
freed from ticks in this manner," 
Great gain in knowledge of blowfly parasites.——"The results of some 
of the systematic work with parasites have been received," reports D.C. 
Parman, Uvalde, Tex, "It has been found that we have at least four genera
