during the year, and both cows have brought forth good healthy 

 calves. The grade calves resulting from the breeding of native 

 cows to the Ayrshire bulls have generally proved greatly superior 

 to the ordinary native scrub animal. Two very good individuals of 

 this breeding are now owned by the station. One of these is a 

 heifer su-ed by the bull Willowmoor John Gray and recently acquired 

 as a promising addition to the station herd, and the other, a bull calf 

 which has been raised by the station. Both of these animals show 

 marked improvement over the native type in both size and general 

 conformation.

Observations in the daily body temperature of the imported cattle, 

 which were begun soon after the introduction of these anmials in 

 October, 1911, have been recorded during the past year. Periods of 

 high temperatures similar to those observed during the preceding 

 year and discussed in the report for 1912 have been noted, and each 

 of the four animals have shown at least one such period during the 

 year covered by this report (figs. 1-4), In some instances these 

 fever periods have not been marked by excessively high tempera- 

 tures and have been of comparatively short duration. In such cases 

 the detection of disease would have been difficult without the use of 

 the cUnical thermometer. On the other hand, however, cases have 

 been dealt with in which the temperatures have risen above 107° F.
