For the purpose of studying " the effect of the disturbing; influence 

 of a change from quiet pasture to crowded fair grounds upon the animal 

 system, as shown by the milk pail," the milk given by each cow in one 

 day ])revious to her removal to the fair grounds, and in 24 hours while 

 at the fair, was weighed and analyzed (gravimetrically). The results 

 are as follows : 



Tolal yields of tn'ilk and milk constituents. 



The suddeu iucrease [iu the case of No. 1] from 19. '2 to 3:5.1 ounces butter fat iu 24 

 hours oa removal from home to strange and disquieting surroundings was most 

 unexpected, but is fully authenticated. * *f * 



Tosummarizethe results obtained, the effects of worry and confusion on the system 

 of cows as shown iuthe iniikilow, appear coullicting, depending upou individuality. 

 Some cows produced more at home amid llieir usual surroundings, while some 

 seemed stimulated by excitement and nervousness, and made a better showing at 

 the fair grounds than they did at home. The data at hand seem to indicate that 

 the tendency of nervous excitement is to lessen quantity of milk ingredients, and to 

 variously effect quality according to the individuality of the animal, the fat being the 

 most variable ingredient. In the light of such results it may be well to consider 

 whether the true " butter test" of a cow should be made under the circumstances 

 attending a great fair, or at home among natural surroundings and away from 

 unnatural excitements. 



. In addition to the above data, the amount and composition of the milk 

 given during 24 hours at the fair grounds, data relative to skimming and 

 churning, and the score of points are given for 3 of the cows which were 

 competing for prizes.
