It is sufficiently proved by the experience of this district, that 

 20 lbs. of meadow-hay suffice for the maintenance of a cow of 

 fair size in store condition : a like result is stated to be obtained 

 from 120 lbs. of turnips per day. The six cows will have then 

 recjuired during the 27 J weeks for their maintenance only —

When cows are in milk, there occurs a much greater activity 

 of the functions; they eat and drink more, evacuate more excre- 

 ment, and, in all probability, spend considerably more food in 

 respiration. Whilst the 17.60 lbs. per day dry matter in 20 lbs. 

 of hay are fjuiid adeijuate fur the maintenance of a cow in a 

 store state, the six cows in milk have eaten on the average 21.37 

 lbs. solid matter per day during the 27 J weeks. When I have 

 fattened cattle together with a number of milk cows of similar 

 size, which gave on an average eight quarts of milk per day, the 

 whole being fed with moist steamed food, and receiving tlie same 

 allowance of green foml, I have found the lattening cattle refuse 

 water, whilst tlie milk rows on the average drank upwards of 40 

 lbs. per day of water given sejtaralely : the eight quarts ui milk
