Somewhat related to the above are the concerts, Sunday evening meetings,

and performances of various kinds which are given under the auspices of

the appropriate committees. Perhaps one of the most profitable evenings

of the winter is when manufacturers and employers are invited to

meet those of the working class who may wish to be present to discuss

in an informal manner questions of common interest. Under the genial

leadership of Mr. Janssen and the director, much of the restraint usual

on such occasions is thrown aside and the employer and employee sit side

by side, and each listens to the undreamed opinions and experiences of

the other. At one of these meetings the question of a shorter work day

was discussed from the standpoint of the employer, the laborer, and the

humanitarian. The investigations of our own Bureau of Labor were quoted

to show the benefits resulting from a shortening of the day of work, and

it is more than likely that the outcome of the discussion will be an

intention on the part of the manufacturer to curtail the hours of work

just as soon as possible, while the laborers, in learning of obstacles

of which they were ignorant, will await more patiently the action

desired.

The classes or individual pupils contribute their services to the

committee in charge of entertainments. This committee sees to it that

three Sunday evenings of each month are provided for, either from the

ranks of home talent or with the aid of outside artists. In the concerts

some of the best performers of the land have gladly taken part, and the

music of the greatest composers has been heard here. As in all other

cases, there is a charge for admission--four cents for one and six

cents for man and wife. A feature here in vogue might well be copied.

In arranging the selections for a concert the effort is made to always

include at least one popular piece, or a song of national, artistic,

or patriotic interest; then on the programme the words of this song

are printed. The audience may be asked to join in the chorus, but even

if this is not practical the people can catch the air, and with the

words before them in later days they can make melody in their homes.

If we recall the class of people for whom these provisions are made,

and keep in mind the limited avenues of enjoyment open to them, we will

appreciate the boon of such a considerate act.

It might be tedious to enumerate the various classes here conducted, and

give even in brief an outline of the methods, experiences, and results.

Each lesson costs from two to four cents, and the pupils--many of whom

have reached middle life--show a commendable zeal in prosecuting their

studies. However, two topics deserve mention--the lessons in mending and

in cooking. Since it is the poorer people who are to be benefited by

the work of Our House, lessons in economy are needed, if not demanded,

and the earlier opportunities for acquiring these lessons have been

meager. The authorities have therefore wisely decided to so instruct the

housewives of these people that their clothing may look well even if

mended and the family meals be palatable though simple. It is believed

that the result of such teaching will make many homes more attractive,

and keep the men from seeking outside of the house conditions which they

should find within.

The clubs also serve as valuable adjuncts to the work in hand. They are

usually groups of persons of the same sex and near the same age who

meet under the guidance of some experienced man or woman for social

intercourse, for practice in debate, playing of chess, the reading of

some standard author, or the discussion of places and peoples. In all

of these meetings, as well as under all circumstances, the people in

attendance are taught polite behavior by example rather than precept,

and every precaution is taken to avoid any reflection or invidious

comparisons that might tend to keep away the people whom Our House is

intended to benefit.

A word might be said about the travel club. Early in each autumn a

proposition is made that during the following summer a trip will be

taken to such and such places, usually naming one near by, within the

kingdom, and another farther away, as Brussels or the upper Rhine.

Persons desiring to visit either of the places named unite in forming

a club. They meet at stated times to listen to accounts of the place

selected, its historical associations, and the points of interest _en

route_, and also to pay into the treasury an amount agreed upon. For

example, last summer one club, upon the saving of a cent a week by each

member, was able to go to Haarlem and spend the day in seeing the city

and the many places of interest in the neighborhood. In another, each

member contributed ten cents a week, and the club was able to make a two

days' trip to Brussels. By this simple means persons otherwise unable to

go beyond the confines of their native city have the opportunity to get

at least a glimpse of the outside world, and under such conditions and

with such special preparations as to obtain from the trip the maximum

interest and profit.

The only thing that is free in Our House is legal advice and the writing

of legal documents. In Amsterdam, as elsewhere, the poorer people have

too frequently an exaggerated idea as to their rights, and rush into

"law" for fatuous protection. Such persons are liable to fall into the

hands of unprincipled lawyers who help to nurse the fancied wrong and

encourage a suit for damages, or put up an idle defense for the sole

purpose of winning a fee. To protect this class by giving them the most

unselfish advice possible, a number of the best lawyers of the city

have cheerfully offered their services, and every Thursday evening from

eight to twelve o'clock one or two stand ready to give gratuitously the

best advice they can upon such legal points as may be presented. That

this service is appreciated may be seen in the fact that from ten to

twenty persons profit by this privilege every evening. On this evening

persons are present for the purpose of writing letters for those unable

to write, and also to draw up legal documents for such as need them.

Mr. Adma van Scheltema--a name closely identified with every good work

in Amsterdam--has organized in Our House art loan exhibits. For one half

of the days during which the exhibit is open there is no charge for

admission, while a slight fee is exacted on the other days. From these

exhibitions much pleasure as well as instruction has been derived, and,

located in a section which sends but few visitors to the art museums,

one can realize that they perform a good work, as missionaries in

cultivating the people's taste.

Such is, in short, an account of a practical charity--a charity, in

truth, not because something is furnished for nothing, but that so much

is given in return for so little. During the past year more than three

thousand persons were registered as enjoyers of the privileges offered.

Mr. Janssen gave the building and in one sense endowed the work; Mr.

Tours gives his time, wisdom, and energy in directing its affairs; they

both ask the wiser men and women of the city to give a few hours of each

month or year. They have not asked in vain, and the cheerful responses

give promise of the coming of the time when the only answer to the

question, "Am I my brother's keeper?" will be an energetic "Yes."

SKETCH OF FRANK WIGGLESWORTH CLARKE.

The great advance which chemical science has made in the United States

during the past thirty years has been brought about by the joint

operation of several factors, of which we may mention the formation and

the influence of chemical societies seeking to further its development,

the intelligent labors of individual investigators cultivating special

fields, and the systematic pursuit of experimental work with reference

to certain definite results. In this shaping of chemical research in

such a way as to make it most efficient, the work and influence of

Frank Wigglesworth Clarke have been prominent and important. His own

labors have been industriously and unselfishly pursued with an eye to

the advancement of the science, and their value has been generally

recognized. It seems as if he had taken to himself a hint thrown out in

one of his earlier scientific papers, and, giving up the transient glory

of brilliant experiments, had devoted himself to setting the science as

far forward as possible in single branches.

Professor CLARKE was born in Boston, March 14, 1847, and was graduated

from the Lawrence Scientific School of Harvard University in 1867.

Two years later, in 1869, he was appointed instructor in chemistry

in Cornell University, the first assistant ever appointed at that

institution. His next position was that of professor of chemistry

and physics in Howard University, Washington, in 1873 and 1874. In

the latter year he became professor of chemistry and physics in the

University of Cincinnati, in a position which he held till 1883, when he

became chief chemist to the United States Geological Survey and honorary

curator of minerals in the United States National Museum, where he still

remains.

Professor Clarke, having become a member of the American Association

for the Advancement of Science in 1869, assisted, in 1875-'76, in the

organization of its section on chemistry, a branch which had theretofore

been but little represented in the Proceedings of the association. Prof.

S. W. Johnson was elected chairman of the new section for the meeting

in 1876 at Detroit, and Professor Clarke was commissioned to make the

necessary efforts to insure a full attendance of chemists and others

interested in the applications of chemistry. In 1888 he presided over

the section; and he has ever been active in building it up, and in the

development of the American Chemical Society.

Professor Clarke has published about seventy-five scientific papers in

various journals, and many popular articles, especially in Appletons'

Journal and the Popular Science Monthly. His first scientific paper, A

New Process in Mineral Analysis, was published in the American Journal

of Science for March, 1869. Other important papers have related to

analytical methods, to the constitution of the tartrates of antimony,

and to topics on chemical mineralogy, including especially the

constitution of the silicates.

Many of his popular articles relate to educational affairs, and present

forcible arguments for a fuller recognition of science in the course of

instruction, and cogent demonstrations of the need of better teaching

of science and better qualified teachers. When occasion has arisen, he

has fearlessly exposed and denounced humbug in education. In a paper on

The Higher Education, published in the seventh volume of the Popular

Science Monthly, having defined the purpose of true education as being

"to develop the mind; to strengthen the thinking faculties in every

possible direction; to render the acquisition of new knowledge easier

and surer; to increase the student's resources; and to render him better

fitted for dealing with the useful affairs of the world," he sets forth

the advantages of science over the ancient and even the modern languages

for the accomplishment of it. Science, he reasons, furnishes as good

an instrument for cultivating the memory, and has the additional

advantage of strengthening the perceptive powers too, for in it the eye,

the ear, and all the instruments of the senses are trained to observe

facts accurately, as they are not trained to so great a degree in

language study. It again takes the lead in the cultivation of the pure

reason; for it gives grand laws and generalizations already deduced or

in process of deduction. "The discovery of these natural laws may be

counted among the greatest achievements of the human mind. To follow

out the processes by which they were discovered gives the mind its most

rigid training, and elevates the tone of thought in many other respects.

The intellect becomes self-reliant and yet conscious of its own weak

points." Also, in æsthetic development, scientific education is put

foremost. "The true student of Nature and her phenomena ever sees order

and symmetry coming out of chaos, and finds the rarest beauty hidden

where to the unaided eye naught but ugliness exists.... Can any student,

who looks upon the universe with vision thus unobscured, fail to find

in his studies the truest æsthetic culture?" But it had been alleged

that the scientific courses had been tried in many American colleges and

found less fruitful than the classical. In answer to this the author

considered the character of most American colleges, the qualifications

of many professed teachers and the methods of study, and showed that

these, as they actually were, were not competent for the conveyance of

genuine scientific instruction.

By the multiplication of competing colleges putting sectarian interests

in the foremost place, the means were divided up and frittered away,

which, concentrated in one institution, would hardly be enough to

enable it to do really effective work. "Each college acts as a drag

on all the others. Libraries, cabinets, and faculties are uselessly

duplicated. Naturally, one result of this state of affairs is a lowering

of educational standards.... Since, on account of this foolish division

of forces, most of these colleges are inadequately endowed, they are

compelled to work short-handed. One professor has frequently several

branches to teach.... In the majority of cases there is a chair of

Latin, a chair of Greek, and then--a chair of 'Natural Science.' Each

linguistic professor is to some degree a specialist; while the one who

teaches science is perforce compelled to be a smatterer. He is expected

to teach half a dozen dissimilar branches, each one being a life work by

itself. He is to be omniscient on about a thousand dollars a year."

That the character of these institutions, as well as their poverty, was

detrimental to the advancement of scientific education was more fully

shown in another article on American Colleges _vs._ American Science,

in the ninth volume of the Monthly. The colleges were described as

being to a large extent denominational institutions, "equipped and

endowed with, due reference to the perpetuation of sound faith, and

incidentally to the encouragement of what is supposed to be learning....

The very fact that a college has been established for theological

purposes, or for ecclesiastical aggrandizement, is adverse to good

scientific research.... Every year professors are chosen, not on account

of scientific ability, but for reasons of a theological or sectarian

character. If two men, one a Baptist and the other a Unitarian, were

candidates for the same professorship in a Baptist university, the

former, even if very much inferior to his rival, would almost certainly

be elected.... Theological soundness in such an institution far outranks

scientific ability. If Laplace had lived in America, no college would

have tolerated him for an instant. Almost any decayed minister, seeking

an asylum, would have beaten him in the race for a professorship."

These conditions were shown to have necessarily a bad effect upon

American science, and to be not likely to arouse or encourage the

scientific spirit. The student "becomes accustomed to regard the

sciences as comparatively unimportant," and "graduates in complete

ignorance both of the methods and of the aims of science, having learned

only a few disconnected facts concerning the great world about him."

Improvement in these conditions, the author argued, must come partly

from within and partly from without. The colleges must reform their

ways, and, not being likely to do it spontaneously, must be helped--by

pressure of public sentiment and, later, of legislation. This suggestion

proved to be introductory to that of a very important line of work, for

the furtherance of which Professor Clarke seems never to have been able

to labor too earnestly and industriously.

"But how," he says, "should public sentiment be properly shaped and made

available for service? How is the natural, though slow, growth to be

fostered and directed? Mainly by the efforts, organized and individual,

of scientific men. Personally, every worker in science should strive

to awaken in the community about him a comprehension of the value

and purposes of his particular branch. In other words, the real

investigators ought to do more toward popularizing their discoveries

instead of leaving that task to amateurs or charlatans. At present,

unfortunately, too many able scientific men depreciate popular work and

hold aloof from it. They do nothing themselves to interest the public,

and then lament the fact that the public does not become interested.

Yet just here is where the beginning must be made. With a wider public

interest in science will come deeper public appreciation, and this will

develop the tendencies necessary for the improvement of our colleges

and schools. Until the people see and recognize the difference between

true investigators and mere collectors of specimens, between original

workers and text-book authors, little real progress will be made."

While these pictures were correct, when made, of a very large number of

American colleges, a vast improvement has taken place since the articles

were written in the quality of instruction given; but there yet remain

too many institutions to which they are still not inapplicable.

This was not the beginning of Professor Clarke's efforts to show men of

science that the true interests of their cause lay in their making their

knowledge easily accessible to the public. In the first volume of the

Monthly he had an article on Scientific Dabblers, the purpose of which,

as he defined it, was, after calling attention to the silly character

of much that was called "popular science," to urge upon true scientific

men the importance of rendering real knowledge more accessible to the

masses. There is a demand for science, he said, "or the trash which

is written would not be read. It works into nearly all departments

of common life, and is, in one way or another, of interest to almost

every one. Yet, as I have already said, the current popular lectures

upon scientific topics are frothy and worthless; the theologian often

misrepresents science for partisan purposes; and the newspapers, with

all the good they may do, are too frequently conducted by those ignorant

of all science. The people ask for knowledge, and unwittingly get much

chaff with their wheat.... Therefore it seems to be time that true

students of science should seek to popularize their learning.... Men of

science constantly lament that the Government does not extend more aid

to scientific research. The Government is a popular one, and the people

must be trained before its help can be expected. Therefore it is for the

interest of the teachers, as well as for the good of the people, that

scientific truths should be popularly put forward in simple, untechnical

language, and made accessible to all."

Later, in his chairman's address before the Chemical Subsection of

the American Association, in 1878, he had this subject in mind, and

mentioned it as part of the work of the section "to attract public

attention to the subjects that interest us, and to do what we can

to secure for chemistry a wider appreciation and greater means for

development.... If the general public," he said later in his address,

"is not interested in chemistry, it is because we as chemists have

neglected a part of our duty. We have but to speak, in order to command

the public ear."

Another side of scientific advancement to which Professor Clarke's

working life has proved him much attached is presented in this address

at the American Association meeting of 1878, and more minutely as to the

particular point we have in mind in an article on Laboratory Endowment,

in the tenth volume of the Popular Science Monthly. In the association

address he insisted strongly upon the physical side of chemical

research, stated briefly as the study of the phenomena which occur

during the reactions in chemical experiments, or of the transformations

of energy, and upon the importance of the co-ordination of studies

separately pursued to the systematic and permanent advancement of the

science; for which purpose he considered endowed laboratories for

research extremely desirable. In such laboratories adequate corps of

thorough specialists should co-operate in those investigations which

individuals could not undertake; every worker should be assigned to

definite, positive duties, the accurate and careful performance of which

would eventually be sure to advance exact knowledge. The work would be

hard routine, and the real value of the institution would be independent

of everything sensational, and would rest upon considerations of the

most severely practical kind. As an example of such work he mentioned

the study of the connection between the composition of a substance

and its physical properties. Supposing this taken up systematically

by a well-organized body of investigators, the first step would be to

determine, carefully and with the utmost rigor, the physical properties

of the elements. Each one of these substances would have to be isolated

in quantity and in a chemically pure condition, such as has never

been attained as to some--a labor which would of itself involve a

great amount of research. Then would come the measurement of physical

relations, thermal, electrical, optical, magnetic, mechanical, and so

on; and the determination of all their "constants" under widely varied

conditions, notably of pressure and temperature; labors which would

in many cases involve the comparative testing of various methods of

research, and often the invention of new experimental processes. The

number of elements and of their compounds which should be taken up in

some regular order, series by series, would afford almost illimitable

fields of research to large numbers of students; all of whom, if

laboring under some plan of systematic co-operation, might contribute

directly and efficiently to the perfection of the science. "One chemist

might undertake to furnish certain of the elements in a perfectly pure

condition; another might carefully determine under varying circumstances

their densities and rates of expansion; a third could work up their

latent and specific heats; a fourth their electrical relations, and so

on. Failure to attain grand results would be impossible. Doubtless

the labor would prove irksome and monotonous, but the reward would be

sure. In five years, more would be done toward rendering chemistry

an exact science than can be accomplished in a century by means of

chemical investigations at present most in vogue." Chemists engaging

in work of this kind would have to make sacrifices, for it would offer

little promise of sensational reputations to be gained through dazzling

discoveries, and would have to look to the ultimate glory of the science

for their chief reward.

Professor Clarke has not omitted to practice what he thus preached; and

while he has not failed to win honors in other fields of the science,

has made it the chief work of his scientific life to advance toward

solution one of the physical problems of chemistry indicated above.

He has taken as his special field of research the "constants," and

of these, the one which is perhaps the most fundamental of all, the

revision of the atomic weights--not by experiments of his own so much

as by comparison and criticism of the work of all who have undertaken

the task, eliminating errors and finding from the sum of the whole

what is the nearest deducible approach to accuracy. In 1872 he sent

to the Smithsonian Institution a compilation entitled A Table of

Specific Gravities, Boiling Points, and Melting Points for Solids and

Liquids. This was accepted by Prof. Joseph Henry, who made it the first

publication of a projected series to be called The Constants of Nature.

To this series Professor Clarke has since contributed Tables of Specific

Heats, of Expansions, and a Recalculation of the Atomic Weights. A new

edition of the Specific Gravities was issued in 1886, and a second

edition of the Atomic Weights in 1897. For the past five years Professor

Clarke has contributed an annual report on atomic-weight determinations

to the Journal of the American Chemical Society, giving each year a

consistent table of values brought thoroughly down to date. These tables

are now used in all parts of the world as standards for reference.
