In Table No. 3, '^Barnes, II., I," "naiiu^s 11., II,'' and 

 *'Barne.s, iV," represent two lieifers and one bull. 

 They are full blooded Angus calves about G mouths old 

 at time of their arrival in Alabama, and were bred in 

 Illinois. February 11 they arrived in Au])nrn, Ala., and 

 Februarv 13 thev were each inoculated with 1 cc of de- 

 febrinated blood derived from the same two-year-old 

 Alabama-bred Jersey heifer. The inoculation fever per- 

 iods are fairly well marked (see Table No. IV), but are 

 somewhat irregular. These calves were fed shorts, corn 

 meal, ^md receivcnl daily from 3 to 4 gallons of milk from 

 two Alabama-bred Jersey cows. The milk very probably 

 had no immunizing power, but it kept these calves in 

 excellent condition to withstand the inoculation fever. 

 They all grew and gained in weight during the inocula- 

 tion period. April 5, 1900, they were taken to the home 

 of their owner, Hon. R. B. Barnes, Opelika, Ala., where 

 they have spent two summers without showing any 

 symptoms of Texas fever. The heifers were turned into 

 tick-infested pastures and the bull was kept by him- 

 self in a small pasture where he did not get many ticks 

 on him the first summer. Consequently in November 

 following the first summer the bull was given a second 

 inoculation of 1^ cc of defibrinated blood. The cattle 

 have suffered no inconvenience from the inoculation, 

 and the exposure to tick inoculation during the second 

 summer. 



The "Little B.'' in Table No. IV. represents an Angus 

 bull calf, bred in Missouri. He arrived at Auburn, Ala., 

 February 20, 1900, and was then about 10 months old. 

 This calf was small and thin at time of arrival, but on 

 Februarv 21 he was inoculated with 1 cc of defibrinated 

 blood from the same Alabama-bred Jersey heifer. No- 

 tice bv the table that his reactions or inoculation fever 

 periods were better marked than were those of the
