TECHNICAL EDUCATION IN AMERICA.

If there is one point more than another in which the exuberant youth and

vitality of the American nation is visible it is in that of education,

the provision for which is on a most generous scale, carried out with a

determination at which the older countries of the Eastern Hemisphere

have only arrived by slow degrees and painful experience. Of course the

Americans, being young, and having come to the fore, so to speak,

full-fledged, have been able to profit by the lessons which they have

derived from their neighbors--though it is none the less to their credit

that they have profited so well and so quickly. Technical and industrial

education has received a more general recognition, and been developed

more rapidly, than the general education of the country, partly for the

reason that there is no uniform system of the latter throughout the

States, but that each individual State and Territory does that which is

right in its own eyes. The principal reason, however, is that to possess

the knowledge, how to work is the first creed of the American, who

considers that the right to obtain that knowledge is the birthright of

every citizen, and especially when the manual labor has to be

supplemented by a vigorous use of brains. The Americans as a rule do not

like heavy or coarse manual labor, thinking it beneath them; and,

indeed, when they can get Irish and Chinese to do it for them, perhaps

they are not far wrong. But the idea of idleness and loafing is very far

from the spirit of the country, and this is why we see the necessity for

industrial education so vigorously recognized, both as a national duty,

and by private individuals or communities of individuals.

From whatever source it is provided, technical education in the United

States comes mainly within the scope of two classes of institutions,

viz., agricultural and mechanical colleges; although the two are, as

often as not, combined under one establishment, and particularly it

forms the subject of a national grant. Indeed, it may be said that the

scope of industrial education embraces three classes: the farmer, the

mechanic, and the housekeeper; and in the far West we find that

provision is made for the education of these three classes in the same

schools, it being an accepted idea in the newer States that man and

woman (the housekeeper) are coworkers, and are, therefore, entitled to

equal and similar educational privileges. On the other hand, in the more

conservative East and South, we find that the sexes are educated

distinct from each other. In the East, there is generally, also, a

separation of subjects. In Massachusetts, for instance, the colleges of

agriculture and mechanics are separate affairs, the students being

taught in different institutions, viz., the agricultural college and the

institute of technology. In Missouri the separation is less defined, the

School of Mines and Metallurgy being the, only part that is distinct

from the other departments of the University.

One of the chief reasons for the necessity for hastening the extension

of technical education in America was the almost entire disappearance of

the apprenticeship system, which, in itself, is mainly due to the

subdivision of labor so prevalent in the manufacture of everything, from

pins to locomotives. The increased use of machinery, the character of

which is such as often to put an end to small enterprises, has promoted

this subdivision by accumulating workmen in large groups. The beginner,

confining himself to one department, is soon able to earn wages, and so

he usually continues as he begins. Mr. C.B. Stetson has written on this

subject with great force and earnestness, and it will not be amiss to

quote a sentence as to the advantages enjoyed by the technically

workman. He says that "it is the rude or dexterous workman, rather than

the really skilled one, who is supplanted by machinery. Skilled labor

requires thinking; but a machine never thinks, never judges, never

discriminates. Though its employment does, indeed, enable rude laborers

to do many things now which formerly could only be done by dexterous

workmen, it is clear that its use has decidedly increased the relative

demand for skilled labor as compared with unskilled, and there is

abundant room for an additional increase, if it is true, as declared by

the most eminent authority, that the power now expended can be readily

made to yield three or four times its present results, and ultimately

ten or twenty times, when masters and workmen can be had with sufficient

intelligence and skill for the direction and manipulation of the tools

and machinery that would be invented."

The establishment of colleges and universities by the aid of national

grants has depended very much for their character upon the industrial

tendencies of the respective States, it being understood that the land

grants have principally been given to those of the newer States and

Territories which required development, although some of the

institutions of the older States on the Atlantic seaboard have also been

recipients of the same fund, which in itself only dates from an act of

Congress in 1862. In California and Missouri, both States abounding in

mineral resources, there are courses in mining and metallurgy provided

in the institutions receiving national aid. In the great grain-producing

sections of the Mississippi Valley the colleges are principally devoted

to agriculture, whereas the characteristic feature of the Iowa and

Kansas schools is the prominence given to industries.

We need not devote attention to the aims and arrangements of the

agricultural colleges proper, but will pass at once to those which deal

with the mechanical arts, dealing first of all with those that are

assisted by the national land grant. Taking them alphabetically, we have

first the State Agricultural College of Colorado, in the mechanical and

drawing department of which shops for bench work in wood and iron and

for forging have been recently erected, this institution being one of

the newest in America. In the Illinois Industrial University the student

of mechanical engineering receives practice in five shops devoted to

pattern-making, blacksmithing, moulding and founding, benchwork for

iron, and machine tool-work for iron. In the first shop the practice

consists of planing, chiseling, turning, and the preparation of patterns

for casting. The ordinary blacksmithing operations take place in the

second shop, and those of casting in the third. In the fourth there is,

first of all, a course of freehand benchwork, and afterward the fitting

of parts is undertaken. In the fifth shop all the fundamental operations

on iron by machinery are practiced, the actual work being carefully

outlined beforehand by drawings. This department of the University

consists, in point of fact, of three separate schools, destined to

qualify the student for every kind of engineering--mining, railway,

mechanical, and architectural. In addition to the shops and machine

rooms, there are well furnished cabinets of geological and mineralogical

specimens, chemical laboratories for assaying and metallurgy, stamp

mill, furnaces, etc., and, in fact, every known vehicle for practical

instruction. The school of architecture prepares students for the

building profession. Among the subjects in this branch are office work

and shop practice, constructing joints in carpentry and joinery, cabinet

making and turning, together with modeling in clay. The courses in

mathematics, mechanics and physics are the same as those in the

engineering school; but the technical studies embrace drawing from

casts, wood, stone, brick, and iron construction, turners' work,

slating, plastering, painting, and plumbing, architectural drawing and

designing, the history and aesthetics of architecture, estimates,

agreements specification, heating, lighting, draining, and ventilation.

The student's work from scale drawing occupies three terms, carpentry

and joinery being taught in the first year, turning and cabinet making

in the second, metal and stone work in the third. A more condensed

course, known as the builder's course, is given to those who can only

stop one year. The machine shop has a steam engine of 16 horse power,

two engines and three plain lathes, a planer, a large drill press, a

pattern shop, a blacksmith's shop, all of the machinery having been

built on the spot. The carpenter's shop is likewise supplied with

necessary machine tools, such as saws, planers, tenoning machine,

whittlers, etc., the power being furnished by the machine shop. At the

date of the last University report, there were 41 students in the

courses of mechanical engineering, 41 in those of civil engineering, 3

in mining engineering, and 14 in architecture. Tuition is free in all

the University classes, though each student has to pay a matriculation

fee of $10, and the incidental expenses amount to about $23 annually. He

is charged for material used or apparatus broken, but not for the

ordinary wear and tear of instruments. It should be mentioned that the

endowment of the Illinois Industrial University is from scrip received

from the Government for 480,000 acres of land, of which 454,460 have

been sold for $319,178. The real estate of the University, partly made

up by donations and partly by appropriations made in successive sessions

by the State of Illinois, is estimated at $450,000.

The Purdue University in Indiana, named after its founder, who gave

$150,000, which was supplemented by another $50,000 from the State and a

bond grant of 390,000 acres, also provides a very complete mechanical

course, with shop instruction, divided as follows:

Bench working in wood for 12 weeks, or 120 hours.

Wood-turning " 4 " " 40 "

Pattern-making " 12 " " 120 "

Vise-work in iron " 10 " " 100 "

Forging in iron and steel " 18 " " 180 "

Machine tool-work in iron " 20 " " 200 "

The course in carpentry and joinery embraces: 1. Exercising in sawing

and planing to dimensions. 2 Application, or box nailed together. 3

Mortise and tenon joints; a plain mortise and tenon; an open dovetailed

mortise and tenon (dovetailed halving); a dovetailed keyed mortise and

tenon. 4. Splices. 5. Common dovetailing. 6. Lap dovetailing and

rabbeting. 7. Blind or secret dovetail. 8. Miter-box. 9. Carpenter's

trestle. 10. Panel door. 11. Roof truss. 12. Section of king-post truss

roof. 13. Drawing model.

The course in wood turning includes: 1. Elementary principles: first,

straight turning; second, cutting in; third, convex curves with the

chisel; fourth, compound curves formed with the gouge. 2. File and

chisel handles. 3. Mallets. 4. Picture frames (chuck work). 5. Card

receiver (chuck work). 6. Watch safe (chuck work). 7. Ball.

In the pattern-making course the student is supposed to have some skill

in bench and lathe work, which will be increased; the direct object

being to teach what forms of pattern are in general necessary, and how

they must be constructed in order to get a perfect mould from them. The

character of the work differs each year. For instance, for the last

year, besides simpler patterns easily drawn from the sand, such as

glands, ball-cranks, etc., there were a series of flanged pipe-joints

for 2½ in. pipes, including the necessary core boxes; also pulley

patterns from 6 in. to 10 in. diameter, built in segments for strength,

and to prevent warping and shrinkage; and, lastly, a complete set of

patterns for a three horse-power horizontal steam engine, all made from

drawings of the finished piece. In the vise work in iron, the chief

requirements are these: 1, given a block of cast iron 4 in. by 2 in. by

1½ in. in thickness, to reduce the thickness ¼ in. by chipping, and then

finishing with the file; 2, to file a round hole square; 3, to file a

round hole into elliptical; 4, given a 3 in. cube of wrought iron, to

cut a spline 3 in. by 3/8 in. by ¼ in., and second, when the under side

is a one half round hollow--these two cuts involve the use of the cope

chisel and the round nose chisel, and are examples of very difficult

chipping; 5, round tiling or hand-vise work; 6, scraping; 7, special

examples of fitting. In the forging classes are elementary processes,

driving, bending, and upsetting; courses in welding; miscellaneous

forging; steel forging, including hardening and tempering in all its

details.

It is worth mentioning that in the industrial art school of the Purdue

University there were 13 of the fair sex as students, besides one in the

chemical school, and two going through the mechanical courses just

detailed, showing that the scope of woman's industry is less limited in

America than in England. The Iowa State Agricultural College has also

two departments of mechanical and civil engineering, the former

including a special course of architecture. The workshop practice, which

occupies three forenoons of 2½ hours each per week, is, however, of more

general character, and is not pursued with such a regard to any special

calling as in the case of the Purdue University.

The Kansas State Agricultural College has a course of carpentry, though

designed rather more to meet the everyday necessities of a farmer's

life. In fact, all the students are obliged to attend these classes, and

take the same first lessons in sawing, planing, lumber dressing, making

mortises, tenons, and joints, and in general use of tools--just the kind

of instruction that every English lad should have before he is shipped

off to the Colonies. This farmer's course in the Kansas College provides

for a general training in mechanical handiwork, but facilities are given

also to those who wish to follow out the trade, and special instruction

is provided in the whole range of work, from framing to stair-building,

as also in iron work, such as ordinary forging, filing, tempering, etc.

Of the students attending this college, 75 percent, are from farmers'

homes, and the majority of the remainder from the families of mechanics

and tradesmen.

The State College of Maine provides courses for both civil and

mechanical engineers, and has two shops equipped according to the

Russian system. Forge and vise work are taught in them, though it is not

the object of the college so much to teach the details of any one trade

as to qualify students by general knowledge to undertake any of them

afterward. A much more complete and thorough technical education is

given in the Massachusetts Institute of Technology at Boston, where

there are distinct classes for civil, mechanical, mining, geological,

and architectural engineering. The following are the particulars of the

instruction in the architectural branch, which commences in the

student's second year, with Greek, Roman, and Mediæval architectural

history, the Orders and their applications, drawing, sketching, and

tracing, analytic geometry, differential calculus, physics, descriptive

geometry, botany, and physical geography. In the third year the course

is extended to the theory of decoration, color, form, and proportion;

conventionalism, symbolism, the decorative arts, stained glass, fresco

painting, tiles, terra-cotta, original designs, specifications, integral

calculus, strength of materials, dynamics, bridges and roofs,

stereotomy. In the fourth year the student is turned out a finished

architect, after a course of the history of ornament, the theory of

architecture, stability of structure, flow of gases, shopwork

(carpentry), etc.

The number of students in this very comprehensive Institute of

Technology was, by the latest report, 390, of whom 138 were undergoing

special courses, 39 were in the schools of mechanical art, and 49 in the

Lowell School of Practical Design. Tuition is charged at the rate of 200

dols. for the institute proper, and 150 dols. for the mechanical

schools, the average expenses per student being about 254 dols. There

are 10 free scholarships, of which two are given for mechanical art. The

Lowell School has been established by the trustee of the Lowell

Institute to afford free technical education, under the auspices of the

Institute of Technology, to both sexes--a large number of young women

availing themselves of it in connection with their factory work at

Lowell. The courses include practical designs for manufactures, and the

art of making patterns for prints, delaines, silks, paperhangings,

carpets, oilcloth, etc., and the school is amply provided with pattern

looms. Indeed, the whole of the appliances for practical teaching at the

Institute are on such a complete scale that at the risk of being a

little tedious it is as well to enumerate them. They comprise

laboratories devoted to chemistry, mineralogy, metallurgy, and

industrial chemistry; there are also microscopic, spectroscopic, and

organic laboratories. In other branches there are laboratories and

museums of steam engineering, mining, and metallurgy, biology and

architecture, together with an observatory, much used in connection with

geodesy and practical astronomy. The steam engineering laboratory

provides practice in testing, adjusting, and managing steam machinery.

The appliances in connection with mining and metallurgy include a

five-stamp battery, Blake crusher, automatic machine jigs, an engine

pulverizer, a Root and a Sturtevant blower, with blast reverberating,

wasting, cupellation, and fusion furnaces, and all other means for

reducing ores. The architectural museum contains many thousand casts,

models, photographs, and drawings. The shops for handwork are large and

well arranged, and include a vise-shop, forge shop, machine, tool, and

lathe shops, foundry, rooms for pattern making, weaving, and other

industrial institutions. The vise-shop contains four heavy benches, with

32 vises attached, giving a capacity for teaching 128 students the

course every ten weeks, or 640 in a year of fifty weeks. The forge-shop

has eight forges. The foundry has 16 moulding benches, an oven for core

baking, and a blast furnace of one-half ton capacity. The

pattern-weaving room is provided with five looms, one of them in

20-harness, and 4-shuttle looms, and another an improved Jacquard

pattern loom. It may safely be said that there is nor an establishment

in the world better equipped for industrial and technical education than

this Institute of Massachusetts.--_London Building News_.

IVORY GETTING SCARCE.--The stock of ivory in London is estimated at

about forty tons in dealers' private warehouses, whereas formerly they

usually held about one hundred tons. One fourth of all imported into

England goes to the Sheffield cutlers. No really satisfactory substitute

for ivory has been found, and millions await the discoverer of one. The

existing substitutes will not take the needed polish.
