THE CULTIVATOR. 
July, 
ANALYTICAL LABORATORY, 
Yale College, New-Haven, Connecticut. 
JOHN P. NORTON, Professor of Scientific Agriculture. 
P'lVHIS Laboratory is now fully organised for instruction in al- 
X branches of analyses connected with the examination of soils, 
manures, mineral.^ ashes, animal and vegetable substances, &c. Full 
courses are given m each of these departments, and also m general 
Chemistry, both organic and inorganic. 
Stud nts can thus fit themselves to become instructors in the vari¬ 
ous branches of Chemistry, or to apply so much of that and kindred 
sciences as may be necessary to the practical pursuit of agriculture 
or manufacturing. The demand for teachers and Professors in the 
various branches of chemistry, especially Agricultural, is now great 
and increasing, so that this is now a fair field for those who have a 
taste for such pursuits. 
A course of Lectures on Scientific Agriculture, by Professor Nor¬ 
ton, commences in January of eacli year, and continues for two and 
a half months. This course is designed especially for the practical 
farmer, and has given great satisfaction to those who have attended 
it in previous years. It embraces a plain connected outline of the 
leading points in improved agriculture, treating in succession of the 
composition of the soil, the plant and the animal; of their connections 
with each other, and of all the improvements in cultivation, manur¬ 
ing, feeding and fattening, which have been adopted in the best agri¬ 
cultural regions. This course is made so plain and practical, that the 
farmer who attends it can understand the whole, and apply it in his 
own experience. 
More can be learned by attendance upon such lectures, by reading 
in connection with theijn, and by associating with others who are also 
desirous of obtaining a better knowledge of their profession than in 
years away from such advantages. The young farmer learns to 
think for himself, to see that a practice is not necessarily right be¬ 
cause it is old, to understand the reasons for all that he does, and with 
this increase of knowledge is better able to make farming profitable 
as well as interesting. 
Board and lodging maybe procured at from $2 to $3 per week, and 
the Ticket for the Lecture is $10. 
In connection with the Lecture is a short Laboratory course, by 
means of which those who desire it, are taught to test soils, manures, 
marls, &c., in-a simple way, and to make many elementary exami¬ 
nations of a highly useful character. The charge for this course is 
$25. 
To those students who go through the full Laboratory course, the 
charge is about $200 per annum, and they can be admitted at any pe¬ 
riod of the year at a proportional charge.

the farmers, as well as for our own interest, to illustrate them by cuts 
and descriptions, as shown in Cultivator for last month, [April ] The 
advantages of the recently adopted improvement are numerous and 
plainly seen, one of which is removing all the gearing and wearing 
parts io the outside of the power, where it is free from dust and dirt, 
&c., and where it may be boxed up, requiring little time or oil to keep 
them in the best possible running order. 
The liability of breakage and wear, and slipping of links and pin¬ 
ions, as in the rack and pinion powers, (and most others) is wholly 
removed. In shipping them, the gears are taken off and packed in a 
box with other things. 
Having sold a large number of the IMPROVED Machines the past 
harvest, all of which, having given entire satisfaction, and when used 
side by side with the most approved of other kinds, having been 
preferred, we do not hesitate to recommend and warrant them equal, 
if not superior, to any before made or sold by us, or of which we 
have any knowledge. 
Our Thresher consists of a small spiked cylinder, about fifteen in¬ 
ches in diameter, and twenty-six inches long, with a substantial 
spiked concave above this cylinder, which is adjustable to the work 
to be done. The feeding table being level, allows the feeder to stand 
erect, and is little annoyed with dust and dirt—and no possibility of 
hard substances getting into the Thresher, to its injury. 
We attach a vibrating or revolving separator to them, which 
serves to separate all the grain from the straw, and leave it with the' 
fine chaff for fanning mil), while the straw is carried off for stack¬ 
ing. 
Having heretofore been obliged to have a large portion of some parts 
of our work done by contract, we have felt the inconvenience and 
want of dependance to be placed upon the quality of materials and 
workmanship; we have now so extended our facilities, as to enable us 
to make all parts of all our own machines, and can now assure the 
public that none but the best work and stock will be offered by us. 
The Two Horse Power Tliresher and Separator is capable, with 
three or four men, of thre-hing from 150 to 200 bushels of wheat or 
rye, and the single one from 60 to 100 bushels, or double that quanti¬ 
ty of oats per day.

T HE attention of the farming public is solicited to the newly im¬ 
proved Railroad Horse Power, as now made by the subscribers. 
Also to their Over-Shot Spike Cylinder Threshers, with Vibrating 
and Revolving Separators. 
Having had much experience 1 in the sale and manufacture of Horse 
Powers and other Agricultural Implements; and being acquainted 
very extensively with the wants of the farmers of this country, as 
well as the character of most of the implements and machines now 
in use, we think we hazard nothing in pronouncing our latest im- 
provea Power far superior to any before made or sold by us, or with 
which we are acquainted. 
At the late Fair of the New-York State Agricultural Society, held 
at Albany, their committee on Horse Powers unanimously awarded 
ns the highest premium for the best Railroad Horse Power, among 
the large number of the most popular and approved kinds of the day, 
which were on exhibition and competition,—it being considered the 
most efficient and durable on the ground. 
As the principal mechanical parts of its construction differ so ma¬ 
terially from those mostly sold by us previously, to the past season, as 
well as from all others now in use, we have thought it an object to 
Kinderhook Wool Depot. 
T HE subscribers will continue to receive and seel Wool on Com¬ 
mission. From long experience, an extensive acquaintance with 
manufacturers, close application, and increased facilities tor transact¬ 
ing business, they hope to give satisfaction to those who may favor 
them with consignments. 
All who desire it can have their clips kept separate. 
Sales will be made invariably for Cash. 
The charges for receiving, sorting and selling will be one and a 
half cents per pound, and insurance, which will be at the rale of 
25 cents on $100 worth of Wool for each term of three months or un¬ 
der. 
It will be observed by our terms for selling, &c., that we we have 
returned to the price charged the first year this enterprize was es¬ 
tablished. The experience of the past two years has fully proved 
that the proprietors cannot be adequately compensated for their labor 
and expenses, at the rate recently charged; consequently they have 
advanced the commission for selling to the price above mentioned.
