The metric weights and measures constitute a SCIENTIFIC SYSTEM;

our weights and measures are a DISORGANIZATION. Naturally one

can expect a GREAT SAVING OF TIME, THOUGHT AND LABOR from the

use of a system, and this is the fact. If one dared introduce

ordinary arithmetical problems into an article like this, it

would be easy to show by examples how a person has to be

something of a master of common fractions in order to solve in

our system common every-day problems, whereas in the metric

system nearly everything is done very simply with decimals. In

our system a mechanic after making a complicated calculation

with common fractions is as likely as not to get his result in

sixths, or ninths, etc., of an inch, whereas his rule reads to

eighths, or sixteenths, and he must reduce his sixths, or

ninths, to eighths, or sixteenths, before he can measure off

his result. In the metric system results always come out in

units of the scale used. The metric system measures to

millimeters or to a unit a trifle larger than a thirty-second

of an inch. In our system one is likely to avoid sixteenths or

thirty-seconds on account of the labor of calculation. Then,

besides, the amount of figuring is so much less in the metric

system. Take the case of a certain problem to find the cubical

contents of a box. Our solution calls for 80 figures and the

metric for 35, and this is a typical case, not one specially

selected. Thus, metric calculations, while only from one third

to two thirds as long, are likely to be two or three times as

accurate, are far easier to understand, and the results can be

immediately measured off. Hence, we waste time in these four

ways. Shakespeare in Hamlet says: "Thus conscience does make

cowards of us all." In like vein it might be said: Thus custom

(in weights and measures) doth make April fools of us all. It

is no exaggeration to say that counting grown-ups solving

actual problems and children solving problems in school we are

sent on much more than a billion such April fool errands round

Robin Hood's barn every year.

Noting how much time is saved in making simple every-day

calculations by using the metric system, suppose that we assume

of the 60 or more millions of adults in active life in this

country, on the average only one in 60 makes such calculations

daily and that only twenty minutes' time is saved each day. Let

us suppose that the value of the time of the users is put at

$2.40 per day or 10 cents for 20 minutes. Then 1,000,000 users

would save $100,000 per day or $30,000,000 per year. But

perhaps some one is saying that much of this time is not really

saved, since many persons are paid for their time and can just

as well do this work as not. The answer to this is that in many

instances such calculations take the time of OTHERS as well as

the person making the calculation. Occasionally a contractor

might hold back, or work to a disadvantage a gang of a score of

workmen while trying to solve a problem that came up

unexpectedly.

An estimate of the value of all weighing and measuring

instruments places the sum at $150,000,000. Thus, we see that

in five years, merely by a saving in TIME--for time is

money--all metric measuring and weighing instruments could be

got NEW at no extra expense. This estimate of the cost of

replacing our weighing and measuring instruments by new metric

ones and of saving time has been made by others with a similar

result.

A matter of very much more importance than that just discussed

is the extra unnecessary expense put upon education, viz., two

thirds of a year for every child in the land. Presumably if the

metric system were in use with us, all our children would stay

in school as long as they now do, thus getting two thirds of a

year farther along in the course of study. Actually, if

arithmetic were made more simple, vast numbers would; stay

longer, since they would not be driven out of school by the

terrible inroads on their interest in school work by dull and

to them impossible arithmetic. If metric arithmetic texts were

substituted for our present texts, it is safe to say children

would average one full year more of education. What the

increased earning power would be from this it would be hard to

estimate, but clearly it would be a huge sum.

Consider also how much more life would be worth living for

children, teachers and parents if a very large portion of

arithmetical puzzles inserted to qualify the children to

understand our crazy weights and measures were cut out of our

text-books. If we were to adopt the metric system, literally

millions of parents would be spared worry, and shame, and fear

lest Johnny fail and drop out of school, or Mary show

unexpected weakness and have to take a grade over again;

uncounted thousands of teachers would be saved much gnashing of

teeth and uttering of mild feminine imprecations under their

breath; and, best of all, the children themselves would be

saved from pencil-biting, tears, worries, heartburns, arrested

development, shame and loss of education!

A committee of the National Educational Association has

recently reported that Germany and France are each two full

years ahead of us in educational achievement, that is, children

in those countries of a certain age have as good an education

as our children which are two years the foreign childrens'

seniors. Surely one of these years is fully accounted for by

the inferiority of our American ARITHMETIC and SPELLING. This

much, at least, of the difference is neither in the children

themselves, nor in the lack of preparation of our teachers, nor

in educational methods.

Professor J. W. A. Young, of the University of Chicago, in his

work on "Mathematics in Prussia," says: "In the work in

mathematics done in the nine years from the age of nine on, we

Americans accomplish no more than the Prussians, while we give

to the work seven fourths of the time the Germans give."

Professor James Pierpont, of Yale, writing in the Bulletin of

the American Mathematical Society (April, 1900), shows a like

comparison can be made with French instruction. Pierpont's

table exhibits only one hour a week needed for arithmetic for

pupils aged 11 and 12! As the advertisements sometimes say,

there must be a reason.

But if the children are kept in school two thirds of a year

longer somebody pays for this extra expense. Now children do

not drop out of school until they are about 12 years of age and

have both appetites and earning power. The number of these

children that drop out each year is probably about 2 1/2

millions. Of this number let us say 1 1/2 millions would

become wage earners, thus passing from the class that are

supported to the class that support themselves and earn a small

wage besides. We have then three items in this count: (1) The

cost to the state in taxes for the education of 2 1/2 million

for two thirds of a year, or $50,000,000; (2) The cost to the

parents for support of 1 1/2 millions for two thirds of a year

at $67 each, or $100,000,000; (3) The wages of 1 1/2 millions

over and above the cost of their support, say $50 each, or

$75,000,000.

The above figures are put low purposely so that they can not be

criticized. It should be remembered that 46 per cent. of our

population is agricultural, and that on the farm, youths of

from 13 to 15 very often do men's and women's work: also that

in many manufacturing centers great numbers of children get

work at relatively good wages, and that the number of

completely idle children out of school is not large.

With these figures in hand let us consider now a kind of debit

and credit sheet against and for our present system of weights

and measures.

Commenting for a moment on the credit side of the above ledger

account, it can be said that recent psychology shows

conclusively that training in common fractions and weights and

measures can not be of much practical help as so-called

culture, or training for learning other things, unless those

other things are closely related to them, and there are not

many things in life so related to them once we had dropped our

present weights and measures.

It may be complained that the expense of changing to the new

system is not taken account of in the above table. The reason

is that that expense would occur once for all. The above table

deals with the ANNUAL cost of our present medieval system.

One powerful reason for the adoption of the metric system

different in character from the others is the ease of cheating

by the old system. In the past the people have been

unmercifully abused through short weights and measures. Many of

the states have taken this matter up latterly and prosecuted

merchants right and left. Nine tenths of this trouble would

disappear with the new system in use.

Let us consider now for a little time the reasons why the

metric system has not been accepted and adopted for use in the

United States. Evidently the great main reason has been that

the masses of the people, in fact all of them except a very

small educated class in science are almost totally uninformed

on this whole question. Such articles as have been published

have almost invariably appeared in either scientific, technical

or educational magazines, mostly the first, so that there has

been no means of reaching the masses, or even the school

teachers with the facts. For another reason the United States

occupies an isolated position geographically, and our people do

not come into personal contact with those in other countries

using the metric system. But there is still another potent

reason. After the United States government legalized the metric

system in 1866, all the school books on arithmetic began

presenting the topic of the metric system, and, quite

naturally, they did it by comparing its units with those of our

system and calling for cross reductions from one system to the

other. No better means of sickening the American children with

the metric system could have been devised. Multitudes of the

young formed a strong dislike for the foreign system with its

foreign names, and could not now be easily convinced that it is

not difficult to learn. Every school boy knows how easy it is

to learn United States money. The boy just naturally learns it

between two nights. The whole metric system UNDER FAVORABLE

CONDITIONS is learned nearly as easily. By favorable conditions

is meant the constant use of the system in homes, schools,

stores, etc. These favorable conditions, of course, we have

never had.

In 1904 an earnest effort was made again both in this country

and Great Britain to have the metric system adopted for general

use. The exporting manufacturers in both countries grew much

concerned over the whole situation. A petition to have the

metric system adopted in Great Britain was signed by over

2,000,000 persons. A bill to make the system mandatory was

passed by the House of Lords and its first reading in the House

of Commons. The forces of conservatism then bestirred

themselves and the bill was held up. Forseeing a movement of

the same kind in this country, the American Manufactures'

Association got busy, laid plans to defeat such movement which

they later did. Strictly speaking this action was not taken by

the association as such but only by a part of it. One fourth of

the membership and probably much more than a fourth of the

capital of the association was on the side for the adoption of

the system. Politically, however, the side opposed to the new

system had altogether the most influence.

Careful study of the whole matter showed that the main cost to

make the change to the new system would be in dies, patterns,

gauges, jigs, etc. A careful estimate put this cost at $600 for

each workman and assuming a million workmen, we have a total

cost of $600,000,000. But we have just seen that the annual

expense of retaining the old system of weights and measures is

over $300,000,000. Thus we see that two short years would

suffice to pay for what seems to the great manufacturers

association an insuperable expense. From all this we see that

the question is not one for N. M. A. bookkeeping, but for

national bookkeeping.

Many well-informed people studying the matter superficially,

think the difficulties in the way of a change to the new system

insurmountable. Thus, they think of the cost to the

manufacturer--which we have just seen to be rather large but

not insurmountable; they think of the changes needed in books,

records, such as deeds, and the substitution of new measuring

and weighing instruments. Germany and all the other countries

of continental Europe made the change. Are we to assume that

the United States can not? That would be ridiculous. Granting

that commerce has grown greatly, so also has intelligence and

capability of the people for doing great things.

Scientists are universally agreed as to the wisdom of the

adoption of the metric system. The country, as a whole, must be

educated up to the notion that sooner or later it is sure to be

universally adopted, that it is only a question of time when

this will be done. Already electrical, chemical and optical

manufacturing concerns use the metric units and system

exclusively. The system is also used widely in medicine and

still other arts. Then all institutions of learning use the

metric system exclusively whenever this is possible. All that

is needed is to complete a good work well begun.

There is one rational objection to the metric system and but

one. It is that 10 is inferior to 12 as a base for a notation

for numbers, but the world is not ready to make this change nor

is it likely to be for generations to come. Moreover, this

improvement is far less important than uniformity in weights

and measures. For these reasons this objection can be passed

over. Men said the metric system would never be used outside of

France; but it has come to be used all over the world. The

prophets said we should never have uniformity as regards a

reference meridian of longitude. But we have. And so it will be

with the adoption of the metric system in the United States and

Great Britain. It is only a question of whether it comes sooner

or later. When that day comes, the meter, a long yard, will

replace the yard, the liter, the quart (being smaller than a

dry and larger than a liquid quart), the kilogram will replace

the pound, being equal to 2.2 pounds, and the kilometer (.6

mi.) will replace the mile. Within a week or so after the

change has been made to the new system, all men in business

will be reasonably familiar with the new units and how they are

used, and within a few months every man, woman and child will

be as familiar with the new system as they ever were with the

simplest parts of the old. So easy it will be to make the

change as far as ordinary business affairs are concerned.

However, for exact metal manufactures years will be needed to

fully change over to the new. Here the plan is to begin with

new unit constructions and new models, as automobiles using new

machinery constructed in the integral units of the metric

system. All old constructions are left as they are and repaired

as they are. This was the plan used in Germany and of course it

works.

In conclusion it can be said that we started with the idea that

the change to the metric system was needed for the sake of

foreign commerce. We now see that we need it also for our own

commercial and manufacturing transactions. If we are to have

the efficiency so insistently demanded by the age in which we

live, then we must have the metric system in use for the

ordinary affairs of daily life of the masses of the people, we

must have it in commercial and manufacturing industries, and we

must have it in education. If efficiency is to be the slogan,

then the metric system must come no matter what obstacles stand

in its way.

ADAPTATION AS A PROCESS

BY PROFESSOR HARRY BEAL TORREY

REED COLLEGE

FOR the physicist and chemist the term adaptation awakens but

the barren echo of an idea. In biology it still retains a

certain standing, though its significance has, in recent years,

been rapidly contracting, as the influence of the conception

for which it stands has waned. Many biologists are now of the

opinion that their science would be better off entirely without

it. They believe it has not only outlived its usefulness, but

has become a source of confusion, if not, indeed, reaction.

Darwin's first task, in the "Origin of Species," was to

demonstrate that species had not been independently created,

but had descended, like varieties, from other species. But he

was well aware that

such a conclusion, even if well founded, would be

unsatisfactory until it could be shown how the innumerable

species inhabiting the world have been modified, so as to

acquire that perfection of structure and coadaptation which

justly excites our admiration.

To establish convincingly the doctrine of descent with

modification as a theory of species, it was necessary for him

to develop the theory of adaptation which we now know as

natural selection.

The origin of adaptive variations gave him, at that time,

little concern. Though keenly appreciative of the problem of

variation which his studies in evolution presented, he

dismissed it in the "Origin" with less than twenty-five pages

of discussion. Such brevity is not surprising, since a more

extended treatment would only have embarrassed the progress of

the argument. In fact, his restraint in this direction enabled

him, first, to avoid the difficulties into which Lamarck, with

his bold attack on the problem of variation, had fallen; and

second, by doing so, to deal the doctrine of Design a blow from

which it has never recovered.

The latter was a service of well-nigh incalculable value to the

young science of biology--and, as it appeared, to modern

civilization as well. But it has not been uncommon, from

Aristotle's day to this, for the work of great men to suffer at

the hands of less imaginative followers. Sweeping applications

of Darwin's doctrine have been repeatedly made without due

regard either for its original object or for the success with

which that object was achieved. So I believe it to be no fault

of Darwin that the growing indifference of European

laboratories toward natural selection should find occasional

expression in such a phrase as "the English disease." Disease,

indeed, I believe we must in candor admit that devotion to it

to be which blinds its devotees to those problems of more

elementary importance than the problem of adaptation, which

Darwin clearly saw but was born too soon to solve.

The problem of species has profoundly changed since 1859. For

Darwin it was perforce a problem of adaptation. For the

investigator of to-day it has become a part of the more

inclusive problem of variation. Along with the logical results

of natural selection he contemplates the biological processes

of organic differentiation. He is no longer satisfied to assume

the existence of those modifications that make selection

possible. In his efforts to control them, the conception of

adaptation as a result has been crowded from the center of his

interest by the conception of adaptation as a process.

The survival of specially endowed organisms, the elimination of

competing individuals not thus endowed, are facts that possess,

in themselves, no immediate biological significance. Selection

as such is not a biological process, whether it is accomplished

automatically on the basis of protective coloration, or

self-consciously by man. Separating sheep from goats may have a

purely commercial interest, as when prunes and apples, gravel

and bullets, are graded for the market. Such selection is, at

bottom, a method of classification, serving the same general

purpose as boxes in a post-office. Similarly, natural selection

is but a name for the segregation and classification that take

place automatically in the great struggle for existence in

nature. The fact that it is a result rather than a process

accounts, probably more than anything else, for its remarkable

effect upon modern thought. It is non-energetic. It exerts no

creative force. As a conception of passive mechanical

segregation and survival, it was a most timely and potent

substitute for the naive teleology involved in the idea of

special creation.

As a theory of adaptation, then, natural selection is

satisfactory only in so far as it accounts for the

"preservation of favored races." It throws no light upon the

origin of the variations with which races are favored. Since it

is only as variations possess a certain utility for the

organism that they become known as adaptations, the conception

of adaptation is inevitably associated with the welfare of

individuals or the survival of races. To disregard this

association is to rob the conception of all meaning. Like

health, it has no elementary physiological significance.

Our profound interest in the problem of survival is natural and

practical and inevitable. But in spite of Darwin's great

contribution toward a scientific analysis of the mechanism of

organic evolution, and in spite of the marvelous recent

progress of medicine along its many branches, the fact remains

that so far as this interest in the problem of survival is

dominant it must continue to hinder adequate analysis of the

problem of adaptation. Indeed, it is in large measure due to

such domination in the past that biology now lags so far behind

the less personal sciences of physics and chemistry. For

survival means the survival of an individual. And there is no

doubt that the individual organism is the most conspicuous

datum in the living world. The few who, neglectful of

individuals and survivals, find their chief interest in living

substance, its properties and processes, are promptly

challenged by the many to find living substance save in the

body of an organism. Thus, in a peculiarly significant sense,

organisms are vital units. And since the individual organism

shows a remarkable capacity to retain its identity under a wide

range of conditions, adaptability or adjustability comes to be

reckoned as the prime characteristic of life by all to whom the

integrity of the individual organism is the fact of chief

importance.

With the use of the words adaptability and adjustability, our

discussion assumes a somewhat different aspect. Instead of

contemplating further the mechanical selection of individuals

on the basis of characters that, like the structure of "the

woodpecker, with its feet, tail, beak and tongue, so admirably

adapted to catch insects under the bark of trees," can not be

attributed to the influence of the external conditions that

render them useful, we are invited to consider immediate and

plastic adjustments of the organism to the very conditions that

call forth the response. For the fortuitous adjustments that

tend to preserve those individuals or races that chance to

possess them, are substituted, accordingly, the direct primary

adjustments that tend to preserve the identity of the reacting

organism. We turn thus from the RESULTS of the selection of

favorable variations to the biological PROCESSES by which

organisms become accommodated to their conditions of life.
