Some six months since obtained through
you copy Of "American Dairying." by
Prof. Arnold, and l have now had time to
read and test some Of the useful matters
described and recommended by him, and l
am happy to say that find his teachings
sound, reliable and very useful and proita-
BILE to me, Notwithstanding l have enjoyed a
good experience 10 dairying.


had, within the past twenty years, con-
structed three milk-houses for setting milk
for butter.making, and though they were
better than those in use generally, construct
ed on the same principles, all were far from
satisfactory to me- l found in american
Dairying" a brief description of Prof Will
kinson's plan of constructing milk-rooms, in
the use Of an air duct, laid in the earth, be-
low the influence Of sun and frost, by which
it is claimed that air can be cooled in sum-
mer, warmed in winter, dried, rid of all
dust aud impurities, aud be supplied to a
close milk room at nearly the same temper
ature little lower than is required in the
milk room. l thought the theory of the
sub-earth air.duct appeared to have the ring
OF common sense, and to be sound in its
philosophy, and felt so confident that it
was so, that called Prof. Wilkinson pro-
fessionally from Byron, ILL.,, where he was
building butter factory, to my place, and
employed him to furnish me with plans for
a mik-house, and purchased of him the
right to use his patented devices. have
carried out his plans faithfully, and have
been using my milk.room No. for some
time, and am happy to say with very great
satisfaction and with greater profit than l
ever have been able to before in fact, | do
not expect ever to see more perfect milk
room than | have. This is a noted dairy
region, aud many of my nOighbors have seen
my dairy in operation, and all acknowledge
it to excel all they ever saw, and as evi.
denCe Of their sincerity, two of them have
had Prof w. locate and plan dairy houses
for them during the past week.


This wonderful and useful invention will
soon work great Improvement in our dairy
farming. No ice or water is used for cooling,
both Of which are troublesome and expensive
and are to me very Questionable in their ef-
feet on milk and butter. | find that the
sub-earth air duct, which is about level, and
one hundred and forty feet in length and
seven and one-half feet in depth, supplies
many times as much air as is required to
change the entire atmosphere in my milk
room every bali-hour, and the air is dis.
charged by the duct into the milk-room con.
tinually at 49,. The temperature of the
out.of.door air has varied from lie below
zero to 500 above, difference of 67o, bat
the change seems to have no effect on the
air discharged by the duct, but it is, as l
have stated, uniform in temperature, at the
extremes named, and at all intermediate
ones. l desire temperature of 62' in my
dairy, and to raise the temperature Of the
duct air l4' use a very small wood stove,
and it is surprising how very little fuel it re.
quirss to produce and maintain that tenn
perature in the milk room, and how little
care it requires to run it in the most salts.

sire every day, no matter what the temper
ature outside is, and my butter realizes me
a considerable sum above the highest market
quotation. l keep perpetual dairy. that is,
