THE EVOLUTION OF COLONIES.

BY JAMES COLLIER.

VI.--INDUSTRIAL EVOLUTION.

The earliest nomadic stage of mankind has left traces in many of the

colonies. The first age of French Canada, of New York, of great part

of North America, was one of hunters and trappers, and it has

continued in the Northwest till recent times. The first brief period

of Rhodesia was that of the big-game hunter. The Boers of the

Transvaal are still as much hunters as farmers. The American

backwoodsman who clears a patch, then sells his improvements to the

first newcomer, and, placing his wife and children and scanty

belongings on a cart, proceeds _da capo_ elsewhere, is a nomadic

pioneer. The stage is in one way or another perpetual, for the class

never quite dies out. The drunken English quarryman who, driven by a

demon of restlessness, continually goes "on tramp," and in his

wanderings covers on foot a space equal to twice the circumference of

the globe, is a demi-savage whose nomadism is only checked by the

"abhorred approaches of old age." If he emigrates, he repeats the old,

wild life as a pick-and-shovel man in Queensland or a quarryman in New

South Wales. The soberer colonial youth, who more luxuriously canters

from farm to farm in New Zealand on the back of a scrub, is a tamer

specimen who settles down when he marries. Nay, the "restless man" who

periodically applies for leave of absence from a colonial legislature

in order to travel in India, China, and Timbuctoo, is a still milder

but not less incorrigible example of the same indestructible type.

The pastoral stage is all but universal. Wherever grass grows (and

there is wild grass almost everywhere) sheep can graze, and where

there are succulent twigs cattle will fatten on them. The South

American _estancias_ and the ranches of Colorado, the cattle runs of

Queensland and northern New Zealand, the sheep runs of Victoria and

New South Wales repeat and perpetuate this stage. The genesis of it

may even now be daily observed. A Manchester accountant who has never

before been astride a horse will in twelve months learn the mysteries

of cattle and sheep farming, then purchase a hundred acres or two from

the colonial Government, gradually clear it of timber, build of his

own trees, with no skilled assistance, a weatherboard cottage, and

take home a swiftly wooed wife to lead with him a rather desolate

existence in "the bush." Or (on a larger scale) a squatter,[1] who is

commonly a gentleman by birth and education, comes out from England

with inherited wealth, buys or leases from the Government a large

inland tract of grazing land, takes with him flocks and herds,

shepherds and stockmen, builds a bark or wooden manor house, and

settles down to the life of Abram on the plains of Mamre. In earlier

days, when the colony was in its infancy, he would not have had to

purchase or lease his "run." One country after another saw the golden

age of a would-be landed aristocracy. As Norman William parceled out

all England among his nobles and knights, rulers of conquered

countries were then mighty free with what did not belong to them.

Possessing the authority of a sovereign, Columbus made lavish grants

of land, and thus pacified his rebels. Charles II presented Carolina

to eight proprietors. Baronies of twelve thousand acres in South

Carolina, manors of twenty thousand acres in Maryland, were dwarfed by

territorial principalities of more than a million acres in New York.

The absolute governors of early Australia gave away wide tracts. When

land was not given it was taken, on Rob Roy's principle. During the

interregnum that followed the recall of the first Governor of New

South Wales, military robbers seized fifteen thousand acres, and under

subsequent administrations they continued their depredations. Land was

held on various tenures. The first American forms were varieties of

belated feudalism; of a hundred often strange and ridiculous emblems

of suzerainty perhaps a dozen repeated Old World customs.[2] Sir H. S.

Maine has proved that nearly all the feudal exactions that maddened a

whole people to mutiny in 1789 were then in force in England. How

shadowy they must have grown is shown by the fact that none of them

was transported to Botany Bay in that or later years. They were

atrophied portions of the British land system when Australia was

founded in 1788. For fully sixteen years the possession of lands

granted or seized was as absolute as the English law ever allows it to

be. Then the landholders, finding the large tracts already conceded

insufficient for the development of the pastoral industry, applied for

more, and themselves suggested in 1803 a plan of leasing crown lands

which in the following year was legalized as "the first charter of

squatterdom"; it was the beginning of a system that has brought under

pastoral occupancy territories as extensive as the largest European

countries. The land system formed part of or gave birth to a political

organization. A host of so-called _seigneurs_ imported into old Canada

as much of the _ancien régime_ as would bear the voyage. Manors in

Maryland reproduced the feudal courts-baron and courts-leet. The great

New York landowners, as inheriting both English and Dutch

institutions, presided in such courts and were at the same time

hereditary members of a powerful legislative order.[3] The courts were

dropped on the way out to Australia, but the political influence of

the English landed aristocracy inhered in their representatives at the

antipodes. As the Southern slavearchy, through its Washingtons and

Jeffersons, Clays and Calhouns, was for three quarters of a century

the driving force in American politics, the Australian squatterarchy

for one generation or more ruled the seven colonies with a sway that

waxed as the absolute power of the governor waned. It composed the

legislature, appointed the judges, controlled the executive, and if

the governor was refractory it sent him home. In both southern

countries social life reflected its tastes and was the measure of its

grandeur. It constituted "society," ran the races, gave the balls, and

kept open house; the surrounding villages lived in its sunshine. Why

could not this patriarchal state last, as it has lasted in Arabia for

thousands of years and in Europe for centuries? In the Southern States

it was brought to bankruptcy by the civil war. In Australia it

collapsed before two enemies as deadly--a succession of droughts and a

fall in the price of wool. The banker has his foot on the squatter's

neck. If one may judge from the published maps, three fourths of the

freehold land in the older colonies is in the hands of the money

lenders. The once lordly runholder, who would have excluded from his

table, or at least from his visiting circle, any one engaged in

commerce, is now the tenant of a mortgage company which began by using

him too well and ended by crushing him unmercifully.

It is also brought to a close by the rise of the agricultural stage.

The colonial _latifundia_ gets broken up for the same economic reasons

as that of the mother country. Whenever from the increase of

population wheat-growing becomes more profitable than grazing, land

rises in value, and vast sheep walks are subdivided into

two-hundred-acre farms, which are put under the plow. The transition

may be retarded in some countries and altogether arrested in others.

Nasse has shown that, in consequence of the moisture of the climate,

there was in the sixteenth century a continual tendency in England to

revert from agriculture to pasture. The light rainfall, high

temperatures, and unfertilized soil will forever keep nine tenths of

Australia under grass. Most of the mountainous north and the

glacier-shaved portions of the south of New Zealand must be perpetual

cattle runs and sheep walks. A century or perhaps centuries will pass

before much of the light soil of Tasmania, hardly enriched by the

scanty foliage of the eucalyptus, is sufficiently fertilized by

grazing to grow corn. Rich alluvial or volcanic lands are put under

the plow, without passing through the pastoral stage, as soon as

markets are created by the advent of immigrants. There is a cry for

farm lands. Companies that have bought large estates break them up

into allotments. When they or other large landholders still resist

pressure, the radical colonial legislature accelerates their

deliberations by putting on the thumbscrew of a statute which

confiscates huge cantles of their land. Or the colonial Government, if

socialist-democratic, purchases extensive properties, which it breaks

up into farms and communistic village settlements. Over wide tracts

the agriculturist, great and small, takes the place of the

pastoralist. He holds his lands under a variety of tenures. New South

Wales, in its search for an ideal form, has flowered into fifteen

varieties. Other colonies are stumbling toward it more or less blindly

through a succession of annual statutes. Where land is abundant the

tenure will be easy. In North America nominal quitrents were general;

the system was long since introduced into South Africa, and it has

lately been imported into New Zealand in spite of all previous

experience to the effect that such rents can not be collected. Mr.

Eggleston remarks that in the United States the tendency was to "a

simple and direct ownership of the soil by the occupant." Since those

days Henry George has come and (alas!) gone. A craze for the

nationalization of the land buzzes in the bonnets of all who have no

land. There is an equal reluctance on the part of colonial

legislatures to grant waste lands as freeholds and on the part of

purchasers to accept them on any other terms. Hence the constant

effort to devise a tenure which shall reserve the rights of the colony

and yet not oppress the tenant. One legislature has blasphemed into

the "eternal lease," which would seem to be almost preferable to

absolute ownership in a country subject to earthquakes! But the

tenure in the early days is unimportant. With a virgin soil yielding

at first seventy and then regularly forty bushels to the acre, and

high prices ruling, the farmer can stand any tenure. Seen at market or

cattle show, his equine or bovine features and firm footing on mother

earth suggest a sense of solidity in the commonwealth to which he

belongs. He gives it its character. The legislature consists of his

representatives. Laws are passed in his interest. He controls the

executive. His sons fill the civil service. Judges sometimes come from

his ranks, and lawyers easily fall back into them. He supports the

churches and fills them. Small towns spring up in place of the

pastoral villages to supply his wants. As the period of the Golden

Fleece was the colonial age of gold, when Jason, the wool king, made a

fortune, received a baronetcy, and, returning to the mother country,

founded a county family and intermarried with the British aristocracy,

so the agricultural stage is the colonial age of silver, in money as

in morals. It lasted in England till well into the century, in Germany

till the other day, in France till now. It is, in the main, the stage

of contemporary colonies. What brings _it_ to an end? The soil gets

exhausted, prices fall, and a succession of wet seasons in New Zealand

or of dry seasons in Australia or South Africa sends the farmer into

the money market. Nearly every province of almost every colony gets

mortgaged up to the hilt. The foot of the land agent is on the neck of

the farmer, who becomes his tenant or serf--_adscriptus glebæ_ as much

as the Old English villeins who were the ancestors of the farmer, or

the Virginia villeins who repeated in the seventeenth century the Old

English status. But tenancy does not always arise out of bankrupt

proprietorship. A capitalist may drain an extensive marsh (like that

along the valley of the Shoalhaven River in New South Wales) and

divide the rich alluvial soil into hundreds of profitable dairy farms.

More inland marshes, like the Piako Swamp in New Zealand, have been so

completely drained as to make the soil too dry to carry wheat, and so

have swamped both capitalists and banker. Where the squatter owner

keeps the land in his own hands, he may lease an unbroken-up tract for

three or five years to a farmer who plows and fences it, takes off

crops, pays a light rent of from five to fifteen bushels per acre, and

leaves it in grass. On one tenure or another the whole colony

gradually comes into cultivation.

The predominance of the agricultural interest is long threatened and

at length shaken by the rise of the industrial stage. It is partly

evolved from the pastoral and agricultural stages and partly

independent. Nor do these stages at once and necessarily give rise to

collective industry. In all young colonies where the population is

scanty and processes are simple there are no division and no

association of labor. The account that one of the best of American

historians gives of the Northwest Territory might be accepted as a

description of this primitive state, and realizes Fichte's ideal of a

_geschlossener Handelstaat_ (closed trade state). Shut in by

mountains, the people raised their own flax and sometimes grew their

own wool, which they spun and wove at home. They made their own

spinning wheels and looms, as they made their own furniture. They

tanned their own leather and cobbled rude shoes of it. Of Indian-corn

husks they spun ropes and manufactured horse collars and chair

bottoms. Barrels and beehives were formed of sawn hollow trees. They

extracted sugar from the maple and tea from the sassafras root. Their

boats were dug-out canoes. In colonies of later foundation this

self-sufficing stage, which repeats an earlier period in the mother

country than the time when the colony was given off, is dropped,

though there are traces of it everywhere to be found. Sheep countries

give birth to the woolen industry. New Zealand reduplicates the woolen

manufactures of England and, owing to protective duties, has attained

a deserved success. New South Wales, with finer wools, has not

succeeded, for no other apparent reason than that she refuses to

impose such duties. For it is to be observed that it is under

legislative protection--bounties, bonuses, drawbacks, export and

especially import duties--that almost every colonial industry has

grown up, as the industries of the mother country grew up. Sometimes

the profit in a particular undertaking is exactly equal to the amount

of the import duty, and it is seldom greater. By taking extravagant

advantage of the liberty long refused (as leave to manufacture was

long refused to the North American colonies), but at length conceded,

to impose import duties, an Australasian colony, misled as much by its

own splendid energy as by evil counselors (Carlyle among them), built

up a whole artificial system of industries which sank in ruinous

collapse when the boom had passed. Independent industries spring first

from the soil. Gold and silver mining lose their wild adventurous

character, and become regular industries, worked by companies with

extensive plants. The digging of gum in Auckland (bled from the

gigantic Kauri pine) is operated by merchants who keep the gum diggers

in a species of serfage. The discovery of coal makes native industries

possible or remunerative, but till iron has been found the system is

incomplete. All countries, and therefore all colonies, are late in

reaching this stage; the most advanced contemporary colonies have not

yet reached it. None the less have they followed England with swifter

steps, if with less momentum, into the modern age of iron--that

Brummagem epoch which has the creation of markets for its war cry,

state socialism for its gospel, Joseph of Birmingham for its prophet,

and the British Empire for its deity.

The iron age is fitly inaugurated by the most degraded relationship

that man can bear to man--that of slavery. Only the oldest of modern

colonies imitate the mother countries in passing through this stage;

in those of later foundation a mere shadow of it remains, or it takes

other shapes. Colonists first enslave the natives of the country where

they settle. In the South American colonies, where they went to find

gold, they would work for no other purpose; they therefore needed the

natives to till the soil; they needed them also as carriers. For these

purposes they were used unscrupulously. They were distributed among

the Spaniards under a system of _repartimientos_ which repeated the

provisions of Greek and Roman slavery, and was itself reduplicated

three centuries later in the convict assignment system of New South

Wales. With such savage cruelty was it worked that, according to the

testimony of Columbus, six sevenths of the population of Hispaniola

died under it in a few years. The same form of slavery, but of a very

different character, prevailed in Africa down almost to our own times.

In the British colonies it was submerged in 1834, from causes exterior

to itself, by the humanitarian wave that wrecked the West Indies; in

the French colonies it was abolished by the revolutionary government

of 1848; in the Dutch colonies it possibly subsists to this day.

Theoretically abolished or not, the relationship between civilized

whites and savage blacks must be everywhere a modified form of

slavery; and a white colonization of the African tropics can only take

place under conditions indistinguishable from a limited slavery. In

colder or younger colonies, even if a more refined sentiment had

permitted it, there could be no question of enslaving the fierce red

Indians, the warlike Maoris, or the intractable Australian blacks. The

Indians rendered some services to the northern colonists. The Maoris

worked for the first immigrants into Canterbury, but as free laborers,

and the phase soon passed away as more valuable labor arrived. Blacks

were in the early years employed by the Australian settlers, but like

nearly all savages they were found incapable of continuous industry.

The next step is to import slaves. To lighten the oppression of the

Mexicans, negroes were introduced, as they had previously been into

Europe. There, and still more in the southern colonies of North

America, they were the chief pioneers. They cut down forests, cleared

the jungles, drained the swamps, and opened up the country. For the

best part of two hundred years the world's sugar, rice, cotton,

tobacco, and indigo were grown by negro labor. The effect on the negro

himself has been to raise him one grade in the scale of being. If, as

Mr. Galton believes, he is naturally two grades below the European, a

place in the "organization of labor" will have to be found for him

midway between the white workman and the slave. It is, indeed, being

found. As a farmer the negro has totally failed. "But he is a good

laborer under supervision. He is a success in the mines. He has found

acceptance in the iron furnaces and about the coke ovens. He is in

great demand in periods of railroad construction," and he is a Western

pioneer. Above born and bred slaves for life there is the status of

imported slaves for a term. For years Kanakas, hired or captured from

the Melanesian Islands of the Pacific, were used as slaves by the

sugar planters of Queensland, until the outcry in England put a stop

to an ill-conducted traffic. It has since been resumed under humaner

conditions, which make it as defensible as slavery can ever be.

Coolies from India are imported into Fiji and Hongkong practically as

free laborers. They are also employed on board the great liners that

ply between India, China, Australia, and England, much to the

discontent of the working class and to the great satisfaction of the

well-to-do, who thus gain cheaper passages and lower freights. The

radical opposition is no more likely to prevent this form of native

labor from spreading to all suitable environments than the

conservative opposition has prevented women from filling the

employments within their improved capacities. The ubiquitous Chinaman,

again, has imported himself into most colonies, and so long as he

takes a place that the white laborer refuses to occupy, he will

present the ugly problem of the coexistence of an indestructible alien

race with a civilized people whose type of civilization and his are

irreconcilable.

European colonies have also known white slavery, as Greek and Roman

colonies knew it, and slavery of their own race and nation, as

European countries knew it. Its most degraded type has doubtless been

Spanish, English, and French convictism. The Australian-English is the

most familiar and the worst. The Australian convict was a slave for

life or a long term. Like the slave, he was at the mercy of his

master, excepting that corporal punishment could not be inflicted by

the master's hands. The lash was none the less kept going; in a single

year, in New South Wales, nearly three thousand floggings were

administered. The Roman _ergastula_ were pleasure bowers compared with

the convict hells of Parramatta, in New South Wales, and Port Arthur,

in Tasmania. Marcus Clarke's terrible fiction proves to be still more

terrible fact. Convicts were herded together like pigs; kindness was

rare, oppression general, and many fine men died inch by inch. Such

was the state of things even after the introduction of the assignment

system. According to that system, convicts were assigned as

agricultural laborers and shepherds to settlers who cried out for

them, as the American planters did for slaves. Craftsmen were allotted

to high officials in lieu of salary or to influential persons who

hired them to others (herein repeating English serfdom) or permitted

them to work for themselves, receiving a portion of their earnings

(herein repeating Greek slavery). Mechanics were employed on public

works, and hundreds of buildings were erected by convict masons,

bricklayers, and carpenters. Day laborers were employed on roads, and

hundreds of miles of solid highway are a durable monument to the

memory of the convict. They were the true pioneers of the country,

braving the dangers of the "bush," resisting the aborigines, clearing

and cultivating the land, and developing the resources of the

colonies. For themselves they did well and ill. Many reformed, and

after manumission, which was at first special and at length general,

became respectable citizens, dealers, and traders. Some grew to be

prosperous merchants, wealthy squatters, editors, legislators, and all

but ministers. Their sons are judges, legislators, solicitors,

Government officials, newspaper proprietors. After lasting for sixty

years the system of transportation was at length abolished in

consequence of the opposition of the working class, who objected to

competition, and of the respectable classes generally. The legislative

body and the large landowners were rather in favor of its perpetuity,

and there are still members of the old "slave-driving party" in

Tasmania who regret its discontinuance.

The bond servants, who were common in New England and at first more

numerous than slaves in the Southern States, repeated the status of

the English serfs. Their origin was various. Crime, debt, sale by

parents, voluntary surrender, and kidnapping all contributed their

quota. The period of indentured service was at first from seven to ten

years, and was ultimately reduced to a fixed term of four years. They

were exchanged and sold like any other commodity. Their treatment

seems to have been often harsh. Like the Australian convicts, many of

them prospered. Leading families in the United States trace their

origin to bondmen. Not a few of the Southern overseers, free laborers,

and small farmers are believed to be descended from them. The vagabond

element in all the States, the "white trash" of the South, and the

criminal and pauper inhabitants of certain regions in the North are

also affiliated on the more degraded sections of the class.[4]

The worst of modern inventions, it has been said, is the invention of

the workingman. The workingman, however, has a pedigree; he is the son

of the bondman or the serf, and the grandson of the slave, who would

have been still more discreditable "inventions" if they had not been

the outgrowth of their time and place. The servile character of the

workman long survived in European countries; it was not till the

beginning of this century that the last trades were emancipated in

England. While in North America and New South Wales the transition is

plainly traceable, all vestiges of it have disappeared in the younger

colonies. In these, almost from the first, the mechanic is master of

the situation. The carpenter who can put up a wooden cottage commands

regular work and high wages, while the preacher who builds him a house

not made with hands is starved. The anomaly is in perfect consistency

with the biological analogy; the brain is everywhere of late

development. As the colony grows, wages fall, and the position of

professional men becomes more tolerable, but, _en revanche_, the

workman acquires and at length almost monopolizes political power. The

premier and cabinet ministers are sometimes former peddlers, gold

diggers, coal miners, shepherds, etc. The legislative bodies consist

largely of labor representatives. Laws are passed in the interest of

labor. Not content with a share of political power out of all

proportion to their numbers or importance, the regimented trades,

under the command of unscrupulous leaders, deliver a pitched battle

against the employers, with the object of gaining practical possession

of the agencies of production and distribution. They are necessarily

defeated. The value of labor and the importance of the mechanic

decline with the application of machinery to all industrial processes.

Accumulated wealth, subsidizing inventions, acquires an increasing

ascendency. The industrial system is in no greater danger from the

onslaughts of labor than civilized countries from the invasion of

barbarians.

Only the beginnings of the commercial epoch, or age of bronze, are to

be found in colonies. In production we witness the same supersession

of individual enterprise by the limited liability company. This is

also the case in distribution, where many obsolete Old World stages

are recapitulated. We may still see the long, slow bullock team, the

wearied pack horse (the fur trade in Canada was carried on by

"brigades of pack horses"), the hawker, purveyor of news and gossip.

We easily trace the evolution of the shop: at first a ship, then

landed, with everything inside--groceries, meat, bread, fruit, and

vegetables, clothes, crockery, ironmongery, stationery, and tobacco;

the butcher first hives off, then the baker, the grocer; in course of

time reintegration takes place, and shops are to be found in the

colonial cities which reduplicate Whiteley's in London, where

everything may again be had as in the beginning. The processes of

exchange likewise recapitulate the past. Barter is long universal, and

is still common in colonial villages. Even then a standard is needed.

In the Old English period the "currency" consisted of cattle, named by

a facetious writer "the current _kine_ of the realm." In Virginia and

Maryland tobacco was the circulating medium for a century and a half,

supplemented in Maryland with hemp and flax; taxes were paid in

tobacco, and rent in kind. In Illinois and Canada, skins and furs,

with wampum for small coin; in New England the latter singular

currency was used far into the eighteenth century. New South Wales has

the demerit of inventing the destructive medium of rum; wages were

paid in it or in wheat; meal or spirits were taken at the doors of

theaters. Store receipts for produce were given by the Government and

passed current, not without depreciation; military officers issued

bills for all sums up to one hundred pounds; private individuals, in

the lack of specie, gave promissory notes. Fixed prices were long

unknown; extortioners in the early days of all the colonies made a

profit of a thousand per cent; and in quite recent days usurious

attorneys exacted interest at the rate of a hundred per cent.

Colonies sometimes anticipate the development of the mother country.

The communistic dreams of the forties in France and England were for a

brief while realized in old Virginia, as they are at this hour being

realized in the village settlements of South Australia; and the state

socialism rendered popular by the German victories of 1870 was perhaps

more thoroughly embodied in convict New South Wales than anywhere else

outside of Peru under the Incas, as it is now sweeping all of the

Australasian colonies onward to an unknown goal.

THE MIND'S EYE.

BY JOSEPH JASTROW.

HAMLET.--My father,--Methinks, I see my father.

HORATIO.--O, where, my lord?

HAMLET.--In my mind's eye, Horatio.

It is a commonplace taught from nursery to university that we see with

our eyes, hear with our ears, and feel with the fingers. This is the

truth, but not the whole truth. Indispensable as are the sense organs

in gaining an acquaintance with the world in which we live, yet they

alone do not determine how extensive or how accurate that acquaintance

shall be. There is a mind behind the eye and the ear and the finger

tips which guides them in gathering information, and gives value and

order to the exercise of the senses. This is particularly true of

vision, the most intellectual of all the senses, the one in which mere

acuteness of the sense organ counts least and the training in

observation counts most. The eagle's eye sees farther, but our eyes

tell us much more of what is seen.

The eye is often compared to a photographic camera, with its eyelid

cap, its iris shutter, its lens, and its sensitive plate--the retina;

when properly adjusted for distance and light, the image is formed on

the retina as on the glass plate, and the picture is taken. So far the

comparison is helpful; but while the camera takes a picture whenever

and wherever the plate happens to be exposed, the complete act of

seeing requires some co-operation on the part of the mind. The retina

may be exposed a thousand times and take but few pictures; or perhaps

it is better to say that the pictures may be taken, but remain

undeveloped and evanescent. The pictures that are developed are

stacked up, like the negatives in the photographer's shop, in the

pigeonholes of our mental storerooms--some faded and blurred, some

poorly arranged or mislaid, some often referred to and fresh prints

made therefrom, and some quite neglected.

In order to see, it is at once necessary that the retina be suitably

exposed toward the object to be seen, and that the mind be favorably

disposed to the assimilation of the impression. True seeing,

observing, is a double process, partly objective or outward--the thing

seen and the retina--and partly subjective or inward--the picture

mysteriously transferred to the mind's representative, the brain, and

there received and affiliated with other images. Illustrations of such

seeing "with the mind's eye" are not far to seek. Wherever the

beauties and conformations of natural scenery invite the eye of man

does he discover familiar forms and faces (Fig. 1); the forces of

Nature have rough-hewn the rocks, but the human eye detects and often

creates the resemblances. The stranger to whom such curiosities of

form are first pointed out often finds it difficult to discover the

resemblance, but once seen the face or form obtrudes itself in every

view and seems the most conspicuous feature in the outlook. The

flickering fire furnishes a fine background for the activity of the

mind's eye, and against this it projects the forms and fancies which

the leaping flames and the burning embers from time to time suggest.

Not all see these fire-pictures readily, for our mental eyes differ

more from one another than the physical ones, and perhaps no two

persons see the same picture in quite the same way. It is not quite

true, however, as many have held, that in waking hours we all have a

world in common, but in dreams each has a world of his own, for our

waking worlds are made different by the differences in what engages

our interest and our attention. It is true that our eyes when open are

opened very largely to the same views, but by no one observer are all

these views, though visible, really seen.

[Illustration: FIG. 1.[5]--The man's face in the rocks is quite

distinct, and is usually readily found when it is known that there is

a face somewhere. (For this view from the Dalles of the St. Croix,

Minn., I am indebted to the courtesy of Mr. W. H. Dudley, of Madison,

Wis.)]

This characteristic of human vision often serves as a source of

amusement. The puzzle picture with its tantalizing face, or animal, or

what not, hidden in the trees, or fantastically constructed out of

heterogeneous elements that make up the composition, is to many quite

irresistible. We turn it about in all directions, wondering where the

hidden form can be, scanning every detail of the picture, until

suddenly a chance glimpse reveals it, plainly staring us in the face.

When several persons are engaged in this occupation, it is amusing to

observe how blind each is to what the others see; their physical eyes

see alike, but their mental eyes reflect their own individualities.

[Illustration: FIG. 2.--In order to see the lion's head, hold the

dollar exactly inverted and the head will be discovered facing the

left, as above outlined. It is clearer on the dollar itself than in

this reproduction.]

Thousands upon thousands of persons handle our silver dollar, but few

happen to observe the lion's head which lies concealed in the

representation of the familiar head of Liberty; frequently even a

careful examination fails to detect this hidden emblem of British

rule; but, as before, when once found, it is quite obvious (Fig. 2).

For similar reasons it is a great aid in looking for an object to know

what to look for; to be readily found, the object, though lost to

sight, should be to memory clear. Searching is a mental process

similar to the matching of a piece of fabric in texture or color, when

one has forgotten the sample and must rely upon the remembrance of its

appearance. If the recollection is clear and distinct, recognition

takes place when the judgment decides that what the physical eye sees

corresponds to the image in the mind's eye; with an indistinct mental

image the recognition becomes doubtful or faulty. The novice in the

use of the microscope experiences considerable difficulty in observing

the appearance which his instructor sees and describes, and this

because his conception of the object to be seen is lacking in

precision. Hence his training in the use of the microscope is

distinctly aided by consulting the illustrations in the text-book, for

they enable his mental eye to realize the pictures which it should

entertain. He may be altogether too much influenced by the pictures

thus suggested to his mental vision, and draw what is really not under

his microscope at all; much as the young arithmetician will manage to

obtain the answer which the book requires even at the cost of a resort

to very unmathematical processes. For training in correct and accurate

vision it is necessary to acquire an alert mental eye that observes

all that is objectively visible, but does not permit the subjective to

add to or modify what is really present.

[Illustration: FIG. 3.--Observe the appearance of these letters at a

distance of eight to twelve feet. An interesting method of testing the

activity of the mind's eye with these letters is described in the

text.]

[Illustration: FIG. 3_a_.]

[Illustration: FIG. 3_b_.]

The importance of the mind's eye in ordinary vision is also well

illustrated in cases in which we see or seem to see what is not really

present, but what for one cause or another it is natural to suppose is

present. A very familiar instance of this process is the constant

overlooking of misprints--false letters, transposed letters, and

missing letters--unless these happen to be particularly striking. We

see only the general physiognomy of the word and the detailed features

are supplied from within; in this case it is the expected that

happens. Reading is done largely by the mental eye; and entire words,

obviously suggested by the context, are sometimes read in, when they

have been accidentally omitted. This is more apt to occur with the

irregular characters used in manuscript than in the more distinct

forms of the printed alphabet, and is particularly frequent in reading

over what one has himself written. In reading proof, however, we are

eager to detect misprints, and this change in attitude helps to make

them visible. It is difficult to illustrate this process

intentionally, because the knowledge that one's powers of observation

are about to be tested places one on one's guard, and thus suppresses

the natural activity of the mind's eye and draws unusual attention to

objective details. Let the reader at this point hold the page at some

distance off--say, eight or twelve feet--and draw an exact

reproduction of the letters shown in Fig. 3. Let him not read further

until this has been done, and _perhaps_ he may find that he has

introduced strokes which were not present in the original. If this is

not the case, let him try the test upon those who are ignorant of its

nature, and he will find that most persons will supply light lines to

complete the contours of the letters which in the original are

suggested but not really present; the original outline, Fig. 3_a_,

becomes something like Fig. 3_b_, and so on for the rest of the

letters. The physical eye sees the former, but the mental eye sees the

latter.

[Illustration: FIG. 4.--For description, see text.]

I tried this experiment with a class of over thirty university

students of Psychology, and, although they were disposed to be quite

critical and suspected some kind of an illusion, only three or four

drew the letters correctly; all the rest filled in the imaginary light

contours; some even drew them as heavily as the real strokes. I

followed this by an experiment of a similar character. I placed upon

a table a figure (Fig. 4) made of light cardboard, fastened to blocks

of wood at the base so that the pieces would easily stand upright. The

middle piece, which is rectangular and high, was placed a little in

front of the rest of the figure. The students were asked to describe

precisely what they saw, and with one exception they all described, in

different words, a semicircular piece of cardboard with a rectangular

piece in front of it. In reality there was no half-circle of

cardboard, but only parts of two quarter-circles. The students, of

course, were well aware that their physical eyes could not see what

was behind the middle cardboard, but they inferred that the two side

pieces were parts of one continuous semicircle. This they saw, so far

as they saw it at all, with their mind's eye.

[Illustration: FIG. 5.--The black and white portions of this design

are precisely alike, but the effect of looking at the figure as a

pattern in black upon a white background, or as a pattern in white

upon a black background, is quite different, although the difference

is not easily described.]

There is a further interesting class of illustrations in which a

single outward impression changes its character according as it is

viewed as representing one thing or another. In a general way we see

the same thing all the time, and the image on the retina does not

change. But as we shift the attention from one portion of the view to

another, or as we view it with a different mental conception of what

the figure represents, it assumes a different aspect, and to our

mental eye becomes quite a different thing. A slight but interesting

change takes place if we view Fig. 5 first with the conception that

the black is the pattern to be seen and the white the background, and

again try to see the white as the pattern against a black background.

I give a further illustration of such a change in Fig. 6. In our

first and natural view of this we focus the attention upon the black

lines and observe the familiar illusion, that the four vertical lines

seem far from parallel. That they are parallel can be verified by

measurement, or by covering up all of the diagram except the four main

lines. But if the white part of the diagram is conceived as the design

against a black background, then the design is no longer the same, and

with this change the illusion appears, and the four lines seem

parallel, as they really are. It may require a little effort to bring

about this change, but it is very marked when once realised.

[Illustration: FIG. 6.--When this figure is viewed as a black pattern

on a white background, the four main vertical lines seem far from

parallel; when it is viewed as a white pattern on a black background

this illusion disappears (or nearly so), and the black lines as well

as the white ones seem parallel.]

A curious optical effect which in part illustrates the change in

appearance under different aspects is reproduced in Fig. 7. In this

case the enchantment of distance is necessary to produce the

transformation. Viewed at the usual reading distance, we see nothing

but an irregular and meaningless assemblage of black and white

blotches. At a distance of fifteen to eighteen feet, however, a man's

head appears quite clearly. Also observe that after the head has once

been realized it becomes possible to obtain suggestions of it at

nearer distances.

[Illustration: FIG. 7.--This is a highly enlarged reproduction taken

from a half-tone process print of Lord Kelvin. It appeared in the

Photographic Times.]

A much larger class of ambiguous diagrams consists of those which

represent by simple outlines familiar geometrical forms or objects. We

cultivate such a use of our eyes, as indeed of all our faculties, as

will on the whole lead to the most profitable results. As a rule, the

particular impression is not so important as what it represents. Sense

impressions are simply the symbols or signs of things or ideas, and

the thing or the idea is more important than the sign. Accordingly, we

are accustomed to interpret lines, whenever we can, as the

representations of objects. We are well aware that the canvas or the

etching or the photograph before us is a flat surface in two

dimensions, but we see the picture as the representation of solid

objects in three dimensions. This is the illusion of pictorial art. So

strong is this tendency to view lines as the symbols of things that if

there is the slightest chance of so viewing them, we invariably do so;

for we have a great deal of experience with things that present their

contours as lines, and very little with mere lines or surfaces. If we

view outlines only, without shading or perspective or anything to

definitely suggest what is foreground and what background, it becomes

possible for the mind to supply these details and see foreground as

background, and _vice versa_.

[Illustration: FIG. 8.--This drawing may be viewed as the

representation of a book standing on its half-opened covers as seen

from the back of the book; or as the inside view of an open book

showing the pages.]

[Illustration: FIG. 9.--When this figure is viewed as an arrow, the

upper or feathered end seems flat; when the rest of the arrow is

covered, the feathered end may be made to project or recede like the

book cover in Fig. 8.]

[Illustration: FIG. 10.--The smaller square may be regarded as either

the nearer face of a projecting figure or as the more distant face of

a hollow figure.]

[Illustration: FIG. 11.--This represents an ordinary table-glass, the

bottom of the glass and the entire rear side, except the upper

portion, being seen through the transparent nearer side, and the rear

apparently projecting above the front. But it fluctuates in appearance

between this and a view of the glass in which the bottom is seen

directly, partly from underneath, the _whole_ of the rear side is seen

through the transparent front, and the front projects above the back.]

[Illustration: FIG. 12.--In this scroll the left half may at first

seem concave and the right convex, it then seems to roll or advance

like a wave, and the left seems convex and the right concave, as

though the trough of the wave had become the crest, and _vice versa_.]
