Tcxap , d. c. Parman (May 31): Horn flies on cattle at Uvalde range 
from a few on each animal to possibly 2,500 at times; recently 
an average of approximately 250 to 500 -ocv animal about normal

ratner serious ^nc at the present time. Yesterday I dad the 
opportunity of .observing about, 275 head of stock in a corral at 
the Speck Bahteh .'in the northwestern part of the County. I do 
H. E. Paris!: (May 50): The situation in Menard County is a 
rather serious one at" the present time. Yesterday I had the 
th( 
not- "believe that I have, ever observed any more horn flies on 
cattle at any. time of the year. The number on each animal is 
hard to .estimate, but I think a very conservative estimate 
Would be between 800 and. 1,000. All bulls observed were very 
heavily infested. I was talking to foremen last week at ranches 
in t he southern part of Schleicher County and they were com- 
plaining about the abundance of flics. It is my opinion that 
■ horn. flies arc more abundant this year then they have been in 
several years. 
E. : W. Laake (June 10): The average number of horn flies per 
animal during the last week did not exceed 20 to 25 on dairy 
stock at Dallas. I 7; as told' at nearly etfery dairy that I visited 
that horn flics were extremely abundant fron about the 15th to th 
last of May. Most of the dairymen estimated the number of flies 
per animal at from 200 to 500. 
0. G. Babcock (June 11): The horn fly is subsiding to a slight 
extent at Sonora. The number of flies per animal will range 
from to , .1,000. On a few c.oys having horns the flics were 
massed at the base of the barn for a distance of about three- 
quarters, of an inch. In two cases the flies vrere massed on the 
back side of the horn for'' a ' diWt&ricte' of- 3 to 4 inches.
