Report OH the Trials of Implements at Oxford. old 
tion of "Mr. T. Ricbanls, of "Wincantoii, and was considered by the judges so 
cheap and practical, that they awarded a silver medal. The stove occupies a 
2 ft. opening, and stands 2 ft. 3 in. high. It can be used cither as an open fire or 
as a close stove. When used as a close stove for cooking, the fire is closed at 
the top but open in front. The hot-plate is 24 inches by 15 inches for boiling, 
stewing, &c., or as an ironing-stove. The oven, placed under the fire, is 14 
inches wide, 13 inches high, and 12 inches deep, and with its flues occupies all 
the width, and so is capable of baking evcrytlung. Tlie flues run completely 
round the oven on each side, and enter a main flue into the chimney. The oven 
is of wrought iron. As an open fire the top is removed and placed against the 
back, and a fall door is let down, and acts as a slo])ing back to the fire, a good 
arrangement, as it is impossible to heap on too much fuel. In the chimney is 
a damper to regulate the draft, and the flues are easily cleaned. Altogether this 
is a very complete range, easily set and reasonable in price, being only 21. 10s. 
Another range contains a small boiler in addition, which increases the cost by 
11. 5s. 
A silver medal was awarded to Mr. Gilbert Murray, of Elvaston, Derby, 
who exhibited articles 7747, 7748, and 7759, models of plant lor cheese 
making on the American factory system, of cheese press, and of a factory 
for 300 cows, and having taken an active part in the establishment of a 
factory at Derby, which has been in operation for some mouths, we are 
indebted to him for an explanation of proceedings, and for a description of 
the processes. A company having been formed, the services of two com- 
petent Americans were secured, and although the subject was only discussed 
in December, the first cheese was made on April 8, The models shown were 
on a scale of IJ inches to the foot. The cans used for conveying the milk 
from the grower to the factoiy are cylindrical, of the same width throughout. 
The lid exactly fits the cylinder like a i)iston, and so accommodates itself 
to the supply of milk, thus preventing waste or undue agitation. In the centre 
of the lid is a tube projecting 6 inches inside ; this, when filled with cold water, 
tends to lower the temperature of the milk. As the evening's milk arrives it is 
emptied into a large tin which stands on the platform of a portable weighing- 
machine, the weight being duly entered in duplicate, one entry going back to 
the sender. In the bottom of the weighing-tin is a brass valve, corresponding to 
a hole in the centre of the weighing-machine platform ; to this valve a small 
brass chain is attached, by which it can be raised and the milk allowed to 
escape into a tin tube, which conveys it direct to the vats in the making room. 
The vats consist of two separate parts ; the outside part is constructed of two- 
inch deal board, tongued and grooved, and supported on wooden legs ; the inner 
case consists of strong tin secured to a rim of 4 inches deep and 2 inches wide ; in 
the inside between the bottoms of the outer and inner vats is a space of 2 inches, 
which contains the steam pipes, and into which cold water is carried in order 
to lower the temperature of the milk when required. As soon as the whole 
of the evening's milk has arrived, and been run into the vats, the cold water 
is turned on and soon fills the space between the vats, about 6 inches from the 
bottom ; and at the contrary end to which the water enters, an overflow pipe 
is inserted, this pipe conveys the water to a small overshot water-wheel, the 
small quantity of water gives a regular but intermittent motion to the wheel ; 
this motion is communicated to a shaft running longitudinally through the 
building, to this shaft are again attached a series of wooden rakes, which float 
on the surface of the milk, and by their action keep up a continuous agita- 
tion, thus preventing any cream from rising. "When the morning's milk 
an-ives it is weighed and run into the vats, and mixed with that of the pre- 
vious evening ; by opening a tap at the bottom of the vat the cold water is all 
run oft", and steam turned on, by an inch pipe running round the inside of the 
vat. This pipe has small perforations throughout its length, and through
