spectivo of wlu'tlicr the water was wai'iii or cold, an increase of 10 

 pounds in (Mcrv 100 ])()unds of Avater dnnik. being acconij^anied by 

 an increa.M' of nearly 1 pound in e\'ery 100 ponnds of milk o;iven. 



(.")) The cows consumed solid food while on warm Avater at the 

 rate of 1.4-1- jiounds for each i)ound of milk ])roduced, and while on 

 cold water at the I'ate of l..")! i)ounds. 



((■)) An increase in the amount of watei' drunk, when the temper- 

 ature of the water remained the same, was associated with an increase 

 in the amount of water in the milk without a notable increase in 

 the total solids. 



(7) An increase in the tem])erature of the water drunk, when the 

 quantity I'eniained the same, was associated with an increase in the 

 total amount of solids produced. 



(8) 'J'here was a daily fluctuation in the ])ercenta!L>-e of water in the 

 milk associated with a fluctuation in the amount of water drunk. 



(J)) Five cows manifested a strono- preference for water at 70^ over 

 that of 82°. but one of the cows showed an even stronger liking for 

 the iced water. 



(10) With but one exception the cows, while they ate less and 

 drank less during the cold water periods, weighed more at their 

 close, and with l)ut three exce]:)tions weighed less at the close of the 

 warm water ])eriods. 



(11) With butter at 20 cents per pound, skim-milk at 2.") cents j^er 

 cwt., corn fodder at $5 per ton, and the cost of warming water for 

 forty cows one hundred and twenty days at $15. the results ol)tained 

 from the cows in this ex])eriment indicate that a net gain of $-21.30 

 Avould be realized on a herd of forty cows averaging 10 pounds of 

 milk pel- cow ]ier day. and at least $10 on a herd of twenty, and $5 on 

 a herd of ten cows. Counting corn fodder at $10 per ton, the net 

 gain on a herd of forty cows would still l)e $12.48.
