AMERICAN AGRICULTURIST. 
[Mat, 
the proposal to establish a creamery in his vicinity. 
Being impressed with the meagre information as to 
the details of such a product readily accessible, and 
desirous that those elsewhere as well as in his own 
neighborhood should have more definite data than 
he has been able to find, he proposes that we shall, 
on his behalf, offer prizes for 
Best Plan and Description of a Creamery. 
These plans must not only cover the building it¬ 
self, but its entire outfit and the arrangement of 
the apparatus to secure the most economical work¬ 
ing of the milk of from 100 to 500 cows. 
Without attempting to enumerate every point to 
be provided for, the following are suggested : 
The Building. —Its location; ease of approach 
with loaded wagons ; plans and elevations suffi¬ 
ciently in detail to work from and drawn to a scale; 
full specifications should accompany the plans, to 
include everything belonging to the building it¬ 
self ; also an estimate of the cost. 
Out-Buildings. —Plans of whatever are neces¬ 
sary are to be given, such as ice-house, boiler and 
engine-house, etc. 
Adjuncts. —The water supply ; drains to carry 
off all the wastes of the establishment; ice-ponds, 
or other sources of ice; a piggery, in case the 
whey is to be fed out, will be needed. 
Heating, Cooling, and Powek.—A boiler and 
pipes for conveying steam; refrigerators or cool 
room for milk, cream, or butter ; steam engine, or 
other motive power. 
Apparatus. —Include everything needed for the 
reception and prompt weighing or measuring the 
milk ; for setting the milk and separating the 
cream; vessels for holding and keeping cream ; 
churns ; butter-workers, and whatever else is ne¬ 
cessary in the production of butter. 
Marketing. —Packages, stamps, moulds, cases, 
delivery tubs, marking plates. 
Skim-AIilk.—T he disposal of this must be con¬ 
sidered, and the necessary apparatus for making 
skim-milk cheese provided. 
Cleanliness. —Provision for thoroughly cleans¬ 
ing every utensil used, the building itself, and 
those therein employed ; also ventilation. 
In the use of the word “ Plans,” it is not re¬ 
stricted to the plans for the building, but comprises 
the entire outfit, or, as the English say, “plant” 
of a creamery. A treatise on butter-making in a 
creamery is not sought, but a full enumeration of 
all the appliances by which it is made is desired, 
together with the probable cost. 
The drawings and necessary descriptive matter, 
written in black ink upon one side only of fools¬ 
cap paper, are to be sent without the author’s 
name. (The name is to be sent in a sealed en¬ 
velope, upon which is a word or motto correspond¬ 
ing with a similar one upon the plan.) 
The plan receiving the prize to become the prop¬ 
erty of the gentleman offering the prize. 
The plans, etc., should be directed to the care of 
Orange Judd Company, marked “ Creamery Plans,” 
and should be in on or before July 1st. 
Eor the best plan, etc., a cash prize of $ 75 . 00 . 
A Butter Dairy for the Farm. 
Prize Offered for Plans. 
In view of the fact that the highest excellence in 
butter-making can only be reached, where the 
operations are carried on in a properly appointed 
building, devotul to no other uses, and that great 
improvements have been made within a few years 
in the appliances and methods of the farm dairy, 
prizes are also offered for a private butter dairy ar. 
ranged for the milk of five up to twenty cows. 
This offer requires plans for a separate building 
and its complete outfit of the apparatus best adapted 
to butter-making on this smaller scale. 
The plans should be made with a view to utiliz¬ 
ing the facilities afforded by an ordinarily well ap¬ 
pointed farm—such as, for example, the water sup¬ 
ply, ice house, etc. The same general conditions 
as for the creamery above given, will be observed. 
For the best plan, etc., a cash prize of $ 35 . 00 . 
DESCRIPTION. 
A full description of the Microscope and its 
accessories, and how to use them, accompanies 
each instrument. The fpllowing is a brief outline : 
A, is a heavy, neatly japanned iron foot, from 
which rise two pillars, B, with trunnions between, 
carrying all the other parts, and allowing the 
Microscope to be used at any desired angle between 
perpendicular and horizontal. These parts are 
strong and solid, to give steadiness. I), a large 
perforated hard rubber stage, to support objects 
examined, with spring clamps, easily adjusted to 
hold slides, etc., or to be removed. E, a revolv¬ 
ing diaphragm, perforated with openings of differ¬ 
ent sizes, to graduate the amount of light desired. 
E, a concave mirror on a movable arm, ar¬ 
ranged to be turned to light coming 
from any direction—to be used below for 
transparent objects, and above (see dot¬ 
ted lines) for opaque objects. C, a 
curved arm, carrying the body 
which is nickel-plated. The body is 
raised or lowered and adjusted with 
great nicety by a very efficient, smooth¬ 
working rack and pinion, moved by 
the milled heads II, (one is hidden 
from sight in engraving). I, two ob¬ 
ject glasses, used separately or to¬ 
gether, according to the power desired. 
The greatest care is taken with these 
object glasses, and we feel sure that 
they are far superior to anything ever 
offered, except for very much higher 
priced instruments. The image pro¬ 
duced by them is again magnified by 
the eye-piece K, (illustrated and de¬ 
scribed on next page). This fits into 
the draw-tube E, 31 inches long, which 
thus allows the body to be materially 
lengthened, and by removing the eye¬ 
piece further from the image, increases 
the magnifying power. The great ad¬ 
vantages of this will be very apparent 
in using it. Every part of the Microscope 
is made in the most thorough workmanlike 
manner , and it is constructed with a view to 
the most efficient service, (see next page. ) 
NEW AMERICAN AGRICULTURIST 
COMPOUND MICROSCOPE. 
Magnifies 100 to 125 Diameters (or 10,000 areas and upward ), with excellent defining power , Jointed Stand, 
fine Rack and Pinion, Movable Eye-Piece and Draw-Tube, Double Object Glasses, Stage, Springs, Revolving 
Diaphragm with different apertures, Mirror adjustable to transparent and opaque objects, etc. Has the prin¬ 
cipal and essential attachments of a $100 Compound Microscope, and ALSO the CAMERA LUCID A. 
The Publishers of the American Agriculturist announce with great pleasure, that after long efforts, 
with the aid and great skill of the Bausch & Lomb Optical Company, they have finally brought the 
above most valuable combination within reach of all those who could not afford the necessarily high cost, 
hitherto, of so desirable an instrument. Though equal in power and essentials to a Microscope and 
Camera Lucida costing $50 and upward, this can be retailed for $15, and to Subscribers to the 
American Agriculturist , for 1879, for whom it was specially designed, but was not completed in time to offer 
before, it will now be supplied for $10. Each instrument, with Camera Lucida, goes in a neat handy 
Walnut Case; also hollowed glass slide, 4 plain slides, 6 thin glass covers, 2 mounted objects, and a 
microscopic treatise, giving full explanations and instructions for use, mounting objects, etc., etc. 
Tin; «il»ove instrumeiit is si most rcmsirlisililc one. For all practical purposes, it 
is as useful as anything ever before offered under $50, or more. Only a few persons pursuing spec¬ 
ial investigations, will need any more powerful or perfect Microscope. Prof. Spencer F. Baird, Secretary 
of the Smithsonian Institution, at Washington, happening into the office on other business, saw 
one of these new American Agriculturist Compound Microscopes on the table, and after examining it 
thoroughly, he pronounced it one of the most complete and handy instruments, for general use, that he 
had ever seen, and immediately ordered one for the Institution—at the same time requesting a good 
supply of the descriptive circulars sent along with it, that he might give them to the large number of 
students and investigators who are from time to time at the Institution, and who want just such an 
instrument.—The highest commendations have also been received from Prof. Asa Gray, of Harvard 
University, and from many other distinguished scientific and professional men.-- No more interesting 
and useful an apparatus could be introduced into any family, in country or city. 
Note. —The first 100 of these Microscopes cost an average expense of over $20 each. We have 
now reached a point where, with all facilities complete, by the use of machinery in constructing the vari¬ 
ous parts, we shall be able to supply them to all our subscribers who want them at $10 each—though the 
regular price to others will be $15. Address Publishers of American Agriculturist.
