The four Nortliern-lurd grades that were hroui^ht to 

 Aiilmrii, Ahi., Noveinher 8, 1S91), witli tlie six full bipods, 

 were inocuhittHl one montli before the full bloods, and 

 were ditrereutly handled and fed. They wexe all in- 

 oculated the first time November 24, 1899, with 1 cc of 

 defil)rinated blood, derived from the same two-year-old 

 Southern-bred Jersey heifer; and on January 24, 1900, 

 they all received a second inoculation of 1^ of detibrin- 

 ated blood. During the inoculation periods they were 

 fed small rations of bran and very poor hay; housed at 

 nii2:ht and bad days, and allowed the run of a dry lot on 

 good days. (See temperature records in Table III). 



Shorthorn Grade Heifer, bred in Missouri, about 8 

 months old at time of arrival in Alabama, and weighed 

 320 11)S. The primary fever began about November 28 

 or December 1, and continued until about December 5th. 

 and rose slightly again December 9, 10 and 11. Her 

 temperature came up again December 18, and irregular 

 slight elevations of temperature occurred until the sec- 

 ond inoculation on January 24. During this first per- 

 iod a low fever prevailed, and the heifer ex- 

 hibited weakness and an unthrifty condition. The 

 low fever following the second inoculation was a little 

 higher and more unbroken or continuous than the fever 

 following the first inoculation. This heifer was not in 

 good condition at the beginning of the inoculation per- 

 iods, and was not fed a sufficient quantity of good feed 

 during the fever. A liberal supply of good feed is always 

 essential during inoculation fever. She was turned 

 into a tick-infested pasture about March 1, and became 

 so badly infested with ticks in April that it Avas neces- 

 sary to get her up and treat her with kerosene oil emul- 

 sion in order to remove them. This heifer did make 

 some growth during her first summer, but did not begin
