0. G. Babcock, Sonora, Tex., reports further on experiments in the 
ecntrol of goat lice: "On November 10, 1931, 472 head of lousy goats at 
the Texas Experiment Station were dipped in 300-mesh wettable stilphur at 
a dilution of 10 pounds of sulphur to 100 gallons of water, at a temper-— 
ature of 64.4°F. All goats were ducked at least four times and held in 
the vat for a minimum of ocne~half minute. On the twentieth day * * * the 
lousy goats, previously marked, showed that one-half * * * were lousy, 
while the other half were free of lice. Thirty one days following the 
second dipping more than 50 head were examined for lice; only 2 live 
and active biting lice were found, one each on 2 goats. The sulphur was 
still present in the mohair, but the mohair had grown about three-fourths 
Soean inch."
