He who stems a stream with sand,

And fetters flame with flaxen band,

Has yet a harder task to prove,

By firm resolve to conquer Love.

Southey, who is convinced that ‘love is indestructible,’ goes so far as

to assert that

They sin who tell us Love can die.

If further evidence of the vitality and power of this passion were

required, an appeal might be made to the language of Hebrew Scripture,

which teaches that ‘Love is strong as death.... Many waters cannot

quench love, neither can floods drown it.’

In view of testimony like this, one might be pardoned for supposing

the point in question satisfactorily established. We shall not,

however, have proceeded far in the consideration of other phases of the

subject, before we shall come upon views which it is by no means easy

to reconcile with the above conclusions. Take, for example, the theory

that a man or a woman can truly love but once. This would seem to be

the natural corollary of the belief that love is indestructible. The

argument, of course, is that the love which departs is not love at all.

As the old lines run:

Pray, how comes Love?

It comes unsought, unsent.

Pray, how goes Love?

That was not love that went.

Carlyle homologates this view. In _Sartor Resartus_, he says: ‘As your

Congreve needs a new case or wrappage for every new rocket, so each

human heart can properly exhibit but one love, if even one; the “first

love which is infinite” can be followed by no second like unto it.’

This is certainly a strong case for the first-and-only-love theory.

But let it not be supposed that we shall here miss the inevitable

differences of opinion. Among others who raise a strong protest against

this view is George Eliot, who believes there is a second love which is

greater, because more mature, than the first. ‘How is it,’ she asks,

‘that the poets have said so many fine things about our first love, and

so few about our later love? Are their first poems the best? or are

not those the best which come from their fuller thought, their larger

experience, their deep-rooted affections? The boy’s flute-like voice

has its own spring charm; but the man should yield a richer, deeper

music.’ Many other quotations to a similar purport might be given; but

the whole argument is a futile one. It is simply reasoning in a circle,

because, whatever may be advanced on this side of the question, it is

of course perfectly open to those who maintain the opposite to fall

back upon the contention that the love which was vanquished was not

love at all, and that its subjugation sufficiently proves that it was

spurious.

It may be said that this is a somewhat rough-and-ready method of

disposing of a profound and delicate psychological problem, and the

point may be further raised in connection with the kindred proposition,

that love is not incurable. Those who hold that love is indestructible

must also, in consistency, maintain that it is likewise incurable, and

inconsolable when scorned and rejected. Then, of course, they are met

with declarations like that of Shakspeare when he says: ‘Men have died

from time to time, and worms have eaten them, but not for love;’ or

like that of Thackeray, when he remarks that ‘Young ladies have been

crossed in love, and have had their sufferings, their frantic moments

of grief and tears, their wakeful nights, and so forth; but it is only

in very sentimental novels that people occupy themselves perpetually

with this passion; and, I believe, what are called broken hearts are

very rare articles indeed.’

At the same time, there are not many who agree that

’Tis better to have loved and lost,

Than never to have loved at all.

Guarini, in his _Faithful Shepherd_, expresses a directly opposite

opinion, holding that it is far harder to lose his lady-love than never

to have seen her or called her his own. Hamlet speaks heavily enough of

‘the pangs of despised love;’ and it would be idle to deny that a large

proportion of the tragedies of real life, as well as of fiction, have

turned upon love rejected, abused, or betrayed. When Dryden says that

Pains of love be sweeter far

Than all other pleasures are,

he must not be supposed to refer to the love that has been blighted by

cold neglect or open disdain. Burns describes the pains of love when

parted from its object in very different language—as ‘A woe that no

mortal can cure.’ Dryden’s reflection is rather in the same strain as

that of the love-sick Hibernian who said it was ‘a moighty recreation

to be dying of love. It sets the heart aching so delicately there’s

no taking a wink of sleep for the pleasure of the pain.’ Moore gives

a less paradoxical and more serious exposition of the case than his

love-sick compatriot:

Yes—loving is a painful thrill,

And not to love more painful still;

But surely ’tis the worst of pain

To love and not be loved again.

Various specifics have been prescribed for the cure of love, and among

these, matrimony has been suggested as an infallible cure. A grim joke,

my masters! but one in which there is only a certain modicum of truth.

Whether, because the love is spurious, or because its fire is less

unquenchable than the poets would have us believe, it is yet too true,

and one of the saddest facts of human experience, that the love which

glows so bright and radiant on the wedding morn, may, before many years

have flown, be cold and dead as the ashes of a fire that has long gone

out.

When the idol is shattered, and love neither dies nor breaks the heart,

it sometimes—and here is another enigma—changes its nature; becomes,

in fact, the opposite of itself. The operation is not without analogy.

The arch-fiend himself was once an angel of light, and so we may find

adoring love become venomous hate.

It is a profitless task to apply the why and the wherefore to

love-affairs. Byron, who himself knew so much about love, says:

Why did she love him? Curious fool, be still;

Is human love the growth of human will?

To assume that it is, would only remove the problem still further from

the point of solution, and would seem, in many instances, to bring

the lover and the madman into still closer relationships. It is the

infatuation of love, and not the prompting of reason, that causes men

and women—but how much more frequently the latter!—to give up, often

for a worthless object, friends, happiness, reputation, wealth, and all

that life holds dear—even, in some cases, life itself. ‘The hind,’ says

Shakspeare, ‘that would be mated with the lion, must die for love;’ yet

such unions and such sacrifices are by no means uncommon—not in the

lower animal kingdom, but in the more exalted and more tangled scheme

of human affairs. Still, despot as he is, with all his huge blunders

and strange tyrannies, Love is perhaps the most welcome and beneficent

guest that knocks at the door of the human heart. Reason has her own

place and her own functions; but it is to Love, after all, that we must

look for the most generous impulses, the noblest inspirations. It is

Love that redeems our life from cold prosaic dullness, that sweetens

and enriches all its springs. There is no more refining and ennobling

influence in the life of man than that of a pure unselfish love. From

such flows every kind of mutual sympathy, mutual comfort, mutual

helpfulness. It is the highest realisation of human bliss.

A NEW PROCESS OF WHITE-LEAD MANUFACTURE.

In two former articles (June 16 and November 10, 1883) we noticed

the dangers to life and health which accompany the manufacture of

white-lead as at present carried on, and we reviewed the several

attempts made to find a substitute. We are still of opinion that such

substitutes will prove effectual in their measure; but we cannot shut

our eyes to the fact that the enormous production and consumption of

ordinary white-lead must nevertheless continue, chiefly on account of

its cheapness, for its enduring qualities, and for its capability for

purposes in jointing, calking, machinery and hydraulic use, which other

substances fail to fulfil. In these circumstances it is interesting

to know that almost coincident with the Report of Mr Redgrave, C.B.,

Her Majesty’s chief Inspector of Factories—to which we alluded in a

former article (June 16), and which so forcibly shows the evils under

the old ‘stack’ process of white-lead manufacture, as usually carried

on—there has been discovered, and brought into full operation, a

process by which white-lead of the purest and best quality is produced

in one-sixth the time, and at considerably less cost than under the

old process. The necessity for the work of women is also avoided, and

the operatives completely secured from contact with the dangerous

white-lead dust.

It may help our readers to an understanding of the subject if we quote

first a brief description of the ‘stack’ process, from a _previous_

Report by Mr Redgrave: ‘The lead is received in “pigs.” These are

melted in a furnace, and then cast in water or in moulds of various

forms best suited for the action of the acetic acid. The acid is placed

in pots of earthenware, on which the moulded lead is placed; and the

pots are then arranged in large chambers, called “stacks,” and covered

with tan. Row after row of pots and tan are placed one above the

other, until the stack is full, in which condition the stack remains

for about three months. Carbonic acid gas is evolved during this time,

escaping through the ventilators, and causes the deposit of white-lead

on the moulds of lead. If the above were the only process, it would be

comparatively innocuous; but it is the work that succeeds from which

the evil of lead-poisoning arises. The tan is carefully removed from

layer after layer; white-lead is found caked upon the moulds of lead;

but a very little motion causes it to break up into powder. The lead,

loaded with this deposit, is then carried in trays, and emptied into

cisterns of water, through which, by agitation, the white-lead passes

to the grinding-mills, and the blue lead is raked out of the cisterns

for further use. After being ground in the wet state, the material

is placed in pans and carried into the ovens to be dried; it is then

carried from the ovens to the warehouse, to be packed in barrels. Such

are the principal processes in which females are employed, and which

are most prolific of disease and death. The injuries to health arise

from the external contact with the skin of the white-lead, whether in

the dry or moist condition, and the inhalation of the dust or powder

into the lungs, or its being imbibed into the stomach through the

mouth. As for the prevention, external or internal, no means have yet

been discovered by which this could be attained. The mitigation of

the evil lies in excessive and enforced cleanliness, with the use of

special clothing and appliances when at work.’

When, however, the testimony given in Mr Redgrave’s _later_ Report

is considered, it will be seen that the ‘excessive and enforced

cleanliness, with the use of special clothing and appliances,’ fail to

accomplish their object, the chief reason being, as testified by one

sufferer: ‘The air of the factory was always full of white-lead dust.’

Another, speaking of her clothes, said: ‘Dust came from them like a

miller, and used nearly to choke me.’ And managers of factories state

to Mr Redgrave: ‘Respirators are provided, but work-people as a rule

will not wear them. The respirators are troublesome.’ The fact is,

there is this dilemma: without the respirators, lungs and stomach get

filled with the dangerous white-lead dust; with the respirators, the

perspiring, half-choked women cannot work. The problem really is how

to produce white-lead without raising this poisonous dust, as it is

well known that the grinding in oil is with any ordinary care perfectly

innocuous. The very stringent legislation lately authorised does not

touch this point.

Attempts have been made to produce white-lead by precipitation, and

thus to avoid some of the dangers; but the product is an inferior

one, being composed of minute crystals which will not blend with the

oil, and are deficient in the most important qualities necessary for

paint, and for the other purposes for which true white-lead is largely

used. The precipitated lead has also to be washed and stored, as the

white-lead from the stack process.

Happily, just at this juncture a simple but wonderful process has been

discovered, perfected and patented by Professor E. V. Gardner, of 44

Berners Street, London, W., for many years Director of the Scientific

Department, and Professor of Chemistry to the Royal Polytechnic

Institution, and who marches with the age in the application of the

wonderful power of electricity to this branch of manufacture. He avails

himself to the full of that great representative of all energy in

forming what is called a galvano-electric combination in the process of

manufacture of white-lead, as follows:

The metallic lead, cast into the form of gratings, and bent into

narrow arches, is closely ranged in order upon wooden trays covered

with pure sheet-tin—the most practically useful electro-negative to

be had. Dipped by mechanical contrivance into a certain acid mixture,

to give a chemically clean surface, and to promote the after-process

of corrosion, they are placed in chambers built of brick, from

twelve feet square and upwards, having a glass roof and windows for

observation, and having a floor of the electro-negative and highly

electro-conductive tin heated from beneath by steam to the necessary

temperature of about one hundred and twenty degrees Fahrenheit.

These chambers may each contain as small a quantity as from eight to

ten tons of lead, and range up to eight hundred or a thousand tons.

Gases, composed of a mixture of acetic acid vapour and atmospheric

air at a similar temperature, are introduced by stoneware pipes from

an ingenious apparatus where they are generated; and passing through

holes in the pipes a few inches from the tin-covered floor of the

chamber, they pass upward, and permeating the whole chamber, electric

action commences. At the end of the second day, there is a beautifully

white surface. On the third day, carbonic acid vapour is introduced

by the same means, hastening still more the formation of white-lead.

This goes on for two weeks, at the close of which time, so active has

been the action of the substances engaged, by reason of the electrical

energy, that there is more white-lead formed than under three months’

working of the same amount of lead by the old process. The gases are

then shut off, the chamber cooled, ventilated, opened, and the contents

withdrawn, the trays being emptied through a special hopper into the

‘agitator,’ a horizontal cage of round iron bars revolving in a closed

case. After being rotated a few minutes, the whole of the white-lead

is disengaged, and falls into a pit underneath, leaving the cores that

have not been converted in the cage, from which they are collected and

remelted for further use. From the pit, the white-lead is conveyed

to the mill by an endless band, on which are fixed a number of small

buckets, which, filling themselves with the white-lead as they pass

through the pit at the bottom, discharge it into the mill as they turn

over at the top, whence, after passing through the crushing-rollers,

the white-lead falls into the mixer, and issues forth, when combined

with oil, in the shape of white-lead of one unfailing quality, being

of perfect character as to body and testing powers, and of the purest

colour.

The work is continuous from first to last. As all the apparatus

is carefully closed in, there is no dust, nor do the hands of the

operatives once touch the material. _The Sanitary Record_ (October

1883) says: ‘Professor Gardner has completely revolutionised the

manufacture of white-lead. Not only has he rendered it a comparatively

innocuous industry, but he has made it a much simpler process,

and reduced the time hitherto required for its production in an

extraordinary manner, and so facilitated its rapid make, and at a much

lessened cost of production. But these great advantages of the process

sink into insignificance when compared with its hygienic working in

rescuing hundreds of poor creatures from lingering illness, not taking

into account the attendant expense of their treatment and support,

which falls on various local authorities.’

Mr Redgrave, having carefully inspected the working of the process,

has written to Professor Gardner as follows: ‘I think it right to

state that having carefully inspected your works at the bottom of Rolt

Street, Deptford, it appears to me that the process of the manufacture

of white-lead there is free from nearly all the objections on the score

of exposure of the persons employed to the injurious effects, hitherto

deemed to be inseparable from the occupation. The material and the

product are alike isolated, there is an absence of dust, and handling

or manipulating is unnecessary.’

As the white-lead manufacturers of our country are not only an

influential and wealthy body, alive to their own interest, but also

most anxious for the welfare of their operatives, they must hail this

new process with much interest, and adopt it gladly. The general public

will rejoice to be assured that the valuable and useful white-lead is

no longer prepared at the cost of life and health to many, especially

women, as has hitherto been the case.

THE SENSITIVE PLANT.

The singular phenomenon exhibited by this well-known exotic has long

been the admiration of the curious, a puzzle to the botanist, and a

standing marvel in the vegetable kingdom. The plant has the property

of contracting certain parts of its structure when touched, and is not

only sensible to the application of force, but appears to be influenced

by the surrounding elements. Sudden degrees of heat or cold, steam from

boiling water, sulphur-fumes, the odour of volatile liquids, in fact

anything that affects the nerves of animals, appears also to affect

the sensitive plant. It is in the highest degree a nervous subject,

and, like that species of the genus _homo_, is in this country a

thorough hothouse habitant. The subject of our present consideration

was originally introduced from Brazil, and, along with other varieties

possessing the same faculty in different degrees, is common to other

parts of South America. The stem of the plant is cylindrical, and

of a green or purplish colour, with two spines at the base of each

leaf, besides a few others scattered about the branches. The leaves

are pinnatifid, or divided into pairs, supported on long footstalks,

and each pinnule is furnished with fifteen or twenty pairs of oblong,

narrow, and shining leaflets. From the base of the leaf-stalks proceed

the peduncles or flower-stalks, each of which supports a bunch of very

small white or flesh-coloured flowers. The seed-vessels are united in

packets of twelve or fifteen each, and are edged with minute spines,

each husk containing three little seeds.

Dr Hook, Dufay, Duhamel, and other naturalists, have studied this plant

with equal attention, and from their observations we learn that it is

difficult to touch a leaf of a healthy mimosa—under which name the

sensitive plant is also known—even in the most delicate manner without

causing it to close. The great nerve which passes along the centre of

the leaf serves as a hinge for the sides to close upon, and this they

do with great exactness, the two sides exactly opposing each other.

If the pressure is made with considerable force, the opposite leaf of

the same pair will be affected at the same time and moved in the same

manner. Upon squeezing the leaf still harder, all the leaflets on the

same side close immediately, as if resenting the affront. The effect

may be even carried so far that the leaf-stalk will bend to the branch

from which it issues, and the whole plant collect itself as it were

into a bundle.

As soon as evening approaches, the sensitive plant begins to lower

its leaves, till at length they rest upon the stem. With the morning

light, they gradually re-open. When the leaves have even faded and

turned yellow, the plant still continues this action, and retains its

sensibility when agitated by external influences. A fine rain will

not disturb the mimosa at all; but should the rain fall heavily, and

be accompanied by wind, the plant becomes immediately affected. When

irritated and made to close by force, the time necessary for the leaves

to recover their usual position varies from ten to twenty minutes,

according to the season and the hour of the day.

Though heat and cold contribute greatly towards its alternate motion,

yet the plant is more sluggish in its movements and less sensitive

in winter than in summer. After a branch has been separated from the

shrub, the leaves still retain their sensibility, and will shut on

being touched. If the end of the detached branch is kept in water, the

leaves will continue to act for some time.

If the sensitive plant be plunged into cold water, the leaves will

close, but will afterwards re-open; and if touched in this state, will

again shut themselves, as if in the open air, but not so quickly. This

experiment does not seem to injure the plant. If the extremity of a

leaf exposed to the rays of the sun is burned with a lens or a match,

it closes instantly; and at the same moment, not only the leaflet

which is opposite to it follows its example, but all that are upon the

same stalk. If a drop of sulphuric acid is placed upon a leaf so as

to remain stationary, the plant is not immediately affected; but when

it begins to spread, the irritation is communicated from one leaflet

to another, till the whole of them on the affected stalk are closed.

Although a branch of this wonderful plant be cut through three-fourths

of its diameter, yet the leaves belonging to it retain the same degree

of sensibility, and open and shut with their usual freedom. The vapour

of boiling water affects the leaves in the same manner as if they were

burned, and for several hours they appear benumbed—in fact, seldom

recovering during the remainder of the day.

These are some of the principal phenomena connected with this very

singular plant. No doubt, other experiments have been made; but these

will serve to show how much akin is the delicate organisation of this

plant to that of the animal kingdom.

Many conjectures have been formed and many theories raised to account

satisfactorily for the working of this exquisite machine; but the

mainspring is still hidden, and has, as far as we know, eluded the

search of the naturalist. It has been supposed by some that the mimosa

is endued with a power of perception which actuates all its motions,

and is the connecting link between the animal and vegetable kingdoms.

But at least an equally rational theory is, that its movements are

purely mechanical. To enter into a discussion as to the relative merits

of these and other theories would exceed the limits of this article. We

can only contemplate the plant as one of those natural wonders which

add to our admiration of mother Nature and her products.

LOVE LIGHTS.

Pretty dreamer, far away,

Where the sheaves are golden,

Listen to a tiny lay

Puck hath late unfolden.

Once a brier loved a rose,

At her feet adoring;

Sweet she glanced from high repose,

Deaf to his imploring.

Came a certain one, yclept

Eros, heaven’s grafter,

Stole a rose-twig, and adept

Fashioned it with laughter—

Fixed it soft with cunning whim

On that hopeless brier,

Till the season saw his stem

Lordly grow, and higher.

Then the maid-rose loved him true,

Wedded to her glory:

Sleep, Mellilla’s eyelids blue;

I have told my story.
