race inheritance ; the Jersey cow is a large milker only through 
individual inheritance, and Mr. Burnett's figures have the im- 
portant significance of directing attention to what the art of man 
can accomplish and to the capabilities of a breed for dairy 
purposes. 
The Jersey cow gives a milk peculiarly adapted for butter 
making, and usually, but not universally, rich. Thus Dr. 
Waller found the milk in one Jersey herd to vary from 2 • 92 per 
cent, of butter fat for one cow to 6 ' 50 per cent, of butter-fat for 
another. The Ayrshire cow presents like variations, but a milk 
not physically as well adapted to butter manipulation, but better 
fitted for cheese. 
These physical relations have an importance which the use 
of the centrifugal machine must ultimately bring into a recog- 
nised practical importance, as does even now the chemical con- 
stitution of milk receive recognition by the practical man. 
There are some individual yields in the Deerfoot herd which 
are deserving of record. We present those of four cows of 
which we have the record for the longest time : —

We call attention to these figures, as they apply to the only 
Jersey herd, so far as we know, which has ventured to publish 
its figures as a herd, and they have indeed a public value. 
Care of the Cows. — The milking time is at 5 A.M. and 5 P.M., 
and the greatest regularity is sought. About eight or nine cows 
are considered sufficient for one milker. In summer the cattle 
are pastured, but driven to their stalls to be milked and to pass 
the night. They here receive some feed, and are consequently 
always quiet and easily herded. In the stable they are bedded 
on sand, according to the custom in this locality. They are 
carded regularly, not only for the sake of looks, but in order to 
secure that cleanliness which is such an essential condition in 
all that relates to the procuring and handling of milk. The 
stables are frequently whitewashed, and no dirt or litter is allowed 
to remain.
