SCHOOL OF APPLIED CHEMISTRY. 
TTNITED States Agricultural Warehouse, No. 195 Front one door 
South of Fulton Street, N. York City. 
Where they have for sale over 200 different patterns and sizes of 
Plows, of the most approved kinds, and suitable for all kinds of 
soil, together with the most extensive assortment of Agricultural 
Implements ever offered for sale in the city of New-York, which 
will be sold at lower prices than they can be purchased at ally other 
establishment. Purcnasers will do well to call and examine their 
stock before purchasing elsewhere. Among the plows advertised 
will be found J. Mayer & Co.’s celebrated and unequalled First 
Premium Plow, without doubt the best and cheapest plow to be had 
in the United States. 
N. B. Castings of all kinds made to order.

EAGLE PLOWS. 
t\JO Plow has been so long before the 
■CN public with so few alterations, come 
into so general use, or received so many 
and so high grade premiums, as the ge¬ 
nuine Eagle Plow, made by the inven¬ 
tors, Messrs. Ruggles, Nourse & Mason. 
Notwilhssanding the great diversity of soils, modes of culture, 
and the constantly increasing competition, and being subjected to the 
most thorough and persevering trials ever had in this country, the 
Eagle Plow still stands at the head of the list for excellence of 
work, materials, durability, workmanship, ease of draft, and price. 
Some of its merits over other kinds in use, are that the metal is 
of such a mixture of irons as gives them strength equal to mallea¬ 
ble iron, and admits of the chilling process on all the wearing 
parts, which causes them to wear sharp, and do three to five times 
the amount of work, as the ordinary kind of plow casting—while 
the risk of breaking is not increased by the process 
All sizes of the above plows constantly on hand at wholesale and 
retail, at manufacturer’s prices, at the Albany Agricultural Ware¬ 
house, Nos. 10 and 12 Green St, Albany. All plows warranted. 
For prices description, &c , see Catalogue, gratis at Store or by

GREATEST IMPROVEMENT OF THE AGE. 
Smith’s Lever Drill. 
Patented November 4, 1846, to H. W. SMITH. 
rpHE advantages of this machine as fully established by use and 
experiment, are 
1. —a saving of from two to three pecks of seed per acre. 
2. —An equal distribution of any given quantity of seed, covered 
at a uniform depth. 
3—A saving of labor; a boy and team, with this machine, can 
complete from 8 to 10 acres per day; and the surface of the soil is 
left m such a position that it does not encrust, and undergoes a con¬ 
stant course of natural cultivation by the action of every shower, 
so that the gases and atmosphere readily penetrate,—hence, 
4. —The grain is not so liable to be thrown out by frost. 
5. —It stands firmer and stronger, and is not so liable to be injured 
by rust or the fly. 
6. —Where these machines have been used, the saving of seed 
and increase of product, amounted to from 20 to 25 per cent. 
The great improvement in this machine, over all others of the 
kind, is its simplicity, durability and economy, and the facility and 
certainty with which it can be set or altered by a regulated index 
and gv.age to drill or plant any given quantity of grain per acre, at 
any given depth. 
These machines are now being made at Syracuse. 
County rights to manufacturers sold on reasonable terms.

July 1—2t. 
Attached to the s ‘ Department of Philosophy and the Arts," in 
Yale College. 
B. Silliman, Jr., Professor of Chemistry and the kindred Sciences 
applied to the Arts. 
J. P. Norton, Professor of Agricultural Chemistry. 
T HE Instructors in this department have opened a commodious 
laboratory on the College grounds, where they are now prepa¬ 
red to receive pupils in special and general chemistry. The system 
pursued with those who design to become chemists or to study the 
science extensively, is thorough and complete. Such students al¬ 
ways commence with an extended course of qualitative examination 
of unknown substances—and in due time pass through a series of 
varied quantitative determinations. To those who wish to follow 
special investigations connected either with the arts, agriculture or 
pure science, every facility will be afforded, both in organic and in¬ 
organic analysis. 
Prof. B. Silliman, Jr., will instruct particularly in general ele¬ 
mentary and analytical Chemistry, Mineralogy and Metallurgy, with 
special reference to their application to the useful arts. He will al¬ 
so give a course of lectures on Mineralogy and Mettallnrgy, conti¬ 
nued through the summer term. During the fall and earlier part of 
the winter, he will also carry a class through a course of elementa- 
ry Chemistry, in elucidation of the regular course on this subject 
n the Academical department. 
The instruction in the Professorship of Agricultural Chemistry is 
intended to unite, as much as possible, braetieal views with theory; 
to give the untaught farmer an opportunity to become acquainted 
with so much of science as shall enable pirn to reason upon his dai¬ 
ly pursuits, and to understand the great principles upon wkich good 
cultivation must depend, presented in so plain a form as to be within 
the comprehension of all. Few chemical terms will be employed 
in the lectures, and those only of the simple explanations; they will 
thus be understood by those who have never devoted any attention 
to the subject. A regular course of lectures will be delivered in 
the winter of each year, commencing in January and continuing 
about two months, there being four lectures in each week. The 
subjects of the course will be—the composition and nature of the 
soil, the plant,and the animal—theories of rotation of crops, and of 
feeding—modes of draining—the different kinds of manures, their 
value and how beneficial—the improvement of waste land, &c. &c. 
Text-books will be indicated for study during leisure hours. 
In connection with the lectures, will be a short course of elemen¬ 
tary Chemistry, for such as wish to study somewhat more of che¬ 
mistry than is given m the course, and to qualify themselves for ma¬ 
king ordinary testings and qualitative examinations of soils, ma¬ 
nures, &c ; this course will occupy two hours of five days in each 
week during two months. 
The fee for the Lectures on Agricultural Chemistry will be $10. 
That for the Elementary Chemical Course, including apparatus 
and reagents, will be $25. 
Students in Analytical Chemistry are allowed to work in the la¬ 
boratory during the whole day; glass will be furnished, (with char¬ 
ges for breakage,) also the ordinary reagents and balances for the 
use of those who are so far advanced as to require them. There 
will be frequent recitations, and the students will receive the con¬ 
stant attention of one or both of the Professors. The fee for this 
class will be $20 per month. 
The vacations will correspond with those in the Academical de¬ 
partments, viz:—six weeks front the third Wednesday of August; 
two weeks from the first Wednesday in January; and four weeks 
from the third Wednesday in April of each year. Sessions begin 
with the close ef each vacation, and are in length respectively, 14— 
14 and 12 weeks. 
Students in this school will enjoy all the advantages to£be derived 
from the extended means of the Institution in Libraries, Instruments 
and Collections. The mineralogical and Geological collection is 
widely known as one of the best in the country, and there are smal¬ 
ler collections in the possession of the Professors. Those who de¬ 
sire it can have access to the Lectures on Chemistry, Mineralogy 
and Geology, by Prof. B. Silliman, Senior, and to the Lectures on 
Nat. ral Philosophy, by Prof. D. Olmsted. 
Instruction is also accessible in higher Mathematics, in Engineer¬ 
ing and the use of Instruments in Philology, History, Oriental Lan¬ 
guages and Belles Lettres. 
The department of Philosophy and the Arts in Yale College, of 
which the School of Applied Chemistry is a part, has been organi¬ 
zed with a view to meet the wants of those who desire to follow 
the studies embraced under it further than they are pursued in a 
collegiate course. Those who desire further information on this 
subject are referred to the annual catalogue of the Institution for 
1847, ’48. 
A college education is not however required of those who become 
students under this department. 
The Professors are always accessible to those who wish to con¬ 
sult them on matters relating to their several departments: and will 
undertake such analyses as may be entrusted to them. Letters of 
inquiry will be promptly attended to.

ROCK SALT. 
T HIS Salt is hard as alum, and is the best known for stock, and 
is the cheapest and most economical—as it may be laid upon 
the ground, or in racks and mangers, where the cattle lick it as 
they may desire, without getting an excess, or suffering injury from 
is use. For sale in any quantity at the Albany Ag. Warehouse
