Deerfoot Farm Centrifugal Dairy. 
7. A probable economy in the fixtures required and in the 
expense of handling. 
It has been observed in foreign experiments that the skim- 
milk makes not as good-quality cheese as ordinary skim-milk. 
This is in part from the absence of fat in it, and in part from 
conditions which as yet seem obscure. 
Our Conviction. — It seems to us that the use of the centrifugal 
machine will ultimately revolutionise the milk interest, although, 
as yet, its use must be deemed experimental only. In time, 
manufacturers will realise what the dairyman requires in a 
machine, and inventive genius will seek its reward in this 
direction. It will be seen that the conditions required for a 
farmer's dairy centrifugal are different from those required for 
the factory where much milk is handled, and where abundance 
of power is at hand. A machine at low cost, one that can be 
revolved at a sufficiently high speed, by such a power as a farm 
can support, will tend to make easier the care of the milk and 
enlarge the profits. A dairy of twenty cows would save enough 
yearly in extra butter produced to pay for a machine. 
In our opinion, the farm machine must belong to the self-de- 
livery class, be one in which the milk can be passed in a steady 
stream, and which will separate the milk into cream in one pail 
and skim-milk in another. It must be simple in construction 
and efficient in action. The time occupied, if not unreasonably 
long, is of little consequence as compared to the economy of 
construction and running, and to efficiency. 
The dairy machine may be larger and more complicated, if 
necessary to secure greater efficiency, and may be intermittent 
or permanent in delivery, as may be found most desirable. 
The use of centrifugal machines for cream-raising will also, 
in our opinion, call attention to the differences between milks, 
and will thus tend toward an increased attention to securing 
uniformity of milk by the use of milk from distinct breeds of 
cows. From a theoretical and experimental position it may be 
prophesied with considerable certainty that the best results will 
occur where large globuled milks are used, and where the feed 
is of a nutritious and succulent character. 
It is also probable that the centrifugal machine may find use 
in the cheese factory in the manufacture of rich cheeses, and it 
is likely that at a less speed than for cream raising it may be 
used to drain the whey from curd. It can certainly find profit- 
able use in city supply. Milk unsold can be quickly and 
cheaply separated into cream for the making of butter, and thus 
souring and other waste prevented. 
Further experimentation is, however, required in order that 
the possibilities of profit to be acquired through the use of this
