a Feeding discontinued after 13 days. 
Ewe 12 was taken off the experiment on August 18, at which time she 
was affected with trembles. She had lost only i pound during these 13 
days. It will be noted that the amount of weed required to cause trem¬ 
bles in these five animals varied from 4^ to 11% pounds and the range 
in time from 5 to 27 days. 
Experiment 4. —In order to determine whether or not trembles is 
infectious, ewes 26 and 12 were put in a small Bermuda grass lot on 
August 18. Two healthy ewes from the flock were put in the same lot 
and all were fed grain in the same trough. It will be recalled that both 
ewe 26 and ewe 12 had typical cases of trembles when their feeding in 
experiments 2 and 3, respectively, was discontinued. Ewe 26 died on 
August 19 and ewe 12 still trembled a week afterwards. However, she 
finally recovered fully. Neither of the other two ewes had developed 
any symptom of trembles when the experiment was discontinued on 
September 4, and both subsequently remained normal. 
Experiment 5.—This experiment was designed to determine the 
length of time that E. ageratoides must be fed to sheep when, after a cer¬ 
tain number of days, the usual grain ration and pasturage are given. 
Two animals were therefore fed for three days on a mixture of equal 
parts of ground weed and grain and were then put on pasture. Two 
others were fed for six days before being placed on pasture and two others 
for nine days, after which they were put on pasture. Table II contains 
the essential facts in this experiment.
