DOG- O 3rt SHEEP POWER. 
Plate XII. 
§ 124. Few more valuable implements, in or about tlie farm, are found than a good, cheap 
and efficient churning power; and few among the great variety of the machines manufac- 
tured at this establishment have met with so general approval and extended sale as the end- 
less dog and sheep power. It is constructed upon two India-rubber straps by means of slats 
riveted to them ; on the upper side of the slats are made fast small buttons which lap past 
the joints of each slat, and each in its turn lapping upon the next thus forms a self-support- 
ing platform, on which the animal walks ; the platform is supported at each end, and at 
proper intervals, along the whole length, with drums or pulleys ; the motion of the endless 
platform giving action to the forward drum, through it to a crank upon one end and to a 
balance wheel upon the other, producing the necessary motion and steadiness required to 
operate the ordinary dash churn. It has also a compensating arrangement upon the side of 
its frame, through which the lever moves up and down, causing it to move the dasher handle 
vertically, without any see-saw or rocking motion, thereby avoiding all friction and resist- 
ance of the dasher and churn. See Plate XII. 
A dog of thirty pounds and upwards, is aU-sufficient for any dairy. It is as much used 
with sheep as dogs, and is not hard work for either. They are fitted with pullies, when 
desired, for driving the Crank Churns, Corn Shellers, Grind Stones, &c. 
Price, comp'ete, with pulley, $15 50

Plate XII. 
§ 125. For hand use the crank churn is perhaps more desirable, as it is more in consonance 
with the muscular system of the human frame, and with a horizontal shaft near the surface of 
the cream in the churn, having fiat arms and blades upon it sweeping downward into and 
through, the cream, the dasher process is observable. Such churns are made of various forms, 
as round and square, and of wood and sheet metal, the most complete of which are those with 
two zinc metal cylinders, the inner one for holding the cream, and the space between them for 
the introduction of hot or cold water to regulate the temperature, which is indicated by insert- 
ing the thermometer in the cream, or what is better, have it fixed in the head of the churn 
in contact with the cream, as shown in Plate XII, center left hand of the page. These are 
the most complete and approved now in use. The prices vary according to size.

COMMON WOOD CYLINDER CTIIJliN. 
Plate XII. 
$ 126. This is seen in the middle back ground of the center of Plate XII, is similar in 
its operation and use as the churn last described. It is a simple wood cylinder with crank 
shaft and beaters, and is perhaps in more general use than any other crank churn. It is the 
cheapest and most simple, and with the use of a thermometer to get the cream at a proper 
temperature, before it is put into the churn, the farmer can churn with it as easy and well as 
with the thermometer churn. Prices and sizes are as follows, for the four sizes now made : 
No. 2— 2 to 5 cows, 6 gallons, - $2 25

ID A S II CHURN. 
Plate XII. 
$ 127. Probably no process known is more correct than that of the common dash churn, 
which is shown as attached in working order to the dog power at right hand lower corner of 
Plate XII. The specific gravity of the particles of butter is much less than that of the 
milk, and they instantly rise to the surface, and each stroke of the dasher carries the 
particles with a compressing force against others below them — the milk itself forming the ful- 
crum. Prices and sizes of dash churns of best white oak or cedar and iron bound,
