CHAPTER IV.

HOLLAND AND BELGIUM, THE LAND OF MARSHES AND OF FEVER, RECLAIMED AND

RENDERED SALUBRIOUS BY THE ENERGIES OF A FREE PEOPLE.

Necessity is the mother of invention. “Quis psittacum loqui docuit?

Venter: Magister artium.”[17] A constant struggle with Nature for

existence taught the Hollander and Brabanter a practical philosophy in

respect of the management of river mouths, tidal rivers, low levels,

freshwater and seawater floods, unmatched by any other nation. It

required the unceasing vigilance of the most experienced scientific

men to combat the adverse circumstances under which their country was

placed. An error of calculation laid waste a province; a breach in a

sea-wall let in upon the land not only the ocean, but famine, followed

by its sure accompaniment--fever, and a wide-spread mortality.

[17] Persius, Sat. Napoleon expressed the same idea when he said,

“The stomach governs Europe.”

In this land there was no room for experimental jobbery. To have

placed a linendraper at the head of the great hydraulic works on

which depended the salubrity and prosperity of Amsterdam or Rotterdam

would have roused the indignation of the country, and brought the

matter to a speedy issue. But it was not until the rise of the Dutch

Republic that there sprung up, as a natural result, a school of

philosophy--of natural philosophy, and of the sciences of observation

and application--hitherto unmatched, a parallel to which can only be

found in the era immediately preceding Alexander the Great. Freedom

of thought and action produced Muschenbroek and Leuwenhoek, De Ruyter

and Van Tromp: then flourished the Elzevir press, and Scaliger was

invited by the traders of Holland to pass his days in peace and plenty

with them, that his presence amongst them might throw a lustre on

their country. In this land flourished Camper and Boerhaave; Albinus

and Ruisch taught anatomy; Swammerdam discovered the globules of the

blood. In the meantime Tasman and Van Diemen explored the ocean,

immortalizing their names and their country by the grandeur of their

geographical discoveries. The views of the traders of this the most

celebrated of all republics, were universal, and included mankind: with

them originated sound political economy. The civilization, peculiarly

human, which overcomes all natural obstacles, reached its height in

this free land; security of life and property, equality before the

law, a contempt for all sinister hereditary influences, a respect

for the natural rights of man, and an appreciation of man’s innate

worth, uninfluenced by all extrinsic circumstances, characterized in

the Netherlands a period standing out in bold relief, and in striking

contrast with the history of all other European nations.[18] In this

forward movement Haarlem was conspicuous, proofs of which may be found

in the Transactions of the society established in that city. About

1771 there was offered a prize for an essay on the Waters of Holland,

as to the existence of any matters injurious to man or beast, and to

describe such, if existing. An unsuccessful candidate for the prize (M.

Vander Wild) advanced in his essay this remarkable principle--that the

sap of plants consists of living beings, in a liquid element.[19]

[18] It has been asserted on good authority, and not contradicted,

that the “Natural Theology” of the celebrated Paley is a mere

translation of a Dutch work.

[19] This principle, so fertile in ideas, will one day, no doubt, be

fully elaborated and studied to its results. These living beings may

prove to be the syphons of perfume and the messengers of colour.

As the nation was free to think and to express their thoughts, nothing

practical or useful escaped them: the question as to the influence

of the drainage of lakes on the health of the inhabitants was ably

discussed during the last century, more especially as to the result

of draining the lowlands of Biensten, de Wonner, &c. M. Ungo Waard

and others describe the sickness which took place on the drainage of

Bleewyksthe. In Haarlem, in 1779, the deaths exceeded those of the

previous year by 396; in Amsterdam, by 1727; in Groningen, by 752. The

previous summer had been hot and dry, offering another proof that the

vegetable humus thus exposed to the air, fermenting and rotting, was

the cause of the sickness and increased mortality. In this land there

was no room--no margin, to use a commercial phrase--for experiments on

the pockets and the health of its citizens; they were citizens, not

subjects--far-seeing men, who calculated everything _d’avance_. And now

the draining of the lake of Haarlem shows that the race has lost little

of its ancient spirit of enterprise and industry, of that applicative

invention to the wants of civilized man which gives to Holland and

to her colonies an aspect to which no other country bears any

resemblance. The poisoning of rivers and streams by any combination of

adventurers could never happen there, and the scenes we have witnessed

lately in England would be wholly unintelligible in Holland. It is

here that vast morasses, seemingly valueless, are being converted into

fertile meadows, by processes of which the natives of other countries

have not the slightest knowledge. In this land it is the law that,

before any one be permitted to convert a peat bog into a lake by the

abstraction of the peat, security is demanded of him as to his means

to drain the lake about to be formed, to embank the excavation, and to

convert it into a healthy fertile meadow; in England, on the contrary,

such cautious procedure is held in the most sovereign contempt, as

wholly unworthy that fine chivalrous character for pluck, daring, and

exciting enterprise and speculation which marks the free-born Briton.

“Break up the cesspools,” shout the interested, “the receptacles of the

filth of millions for a quarter of a century, and pour them at once

into the Thames.” “It will poison the river and the adjoining country

for a lengthened period,” suggests the prudent observer of passing

events. “Persevere,” exclaims the go-ahead party; “have we not proofs

in Macculloch that nearly all known diseases arise from the cesspools?

Leave the river to take care of itself.” What, in the mean time, is

the course of action of the Mayor and Corporation of the richest city

in the world? Fully occupied with the distribution of their revenues,

they abandon the river and interests of a vast metropolis to a host

of talented and needy adventurers, whose name is legion. The people

in Holland and Belgium think that the refuse and excreta of the

inhabitants of towns, villages, and single houses cannot be too soon

or too effectually buried under or incorporated with the soil; we, in

this country, act evidently from a belief that this refuse, the product

of civilization, cannot be too extensively spread abroad in the open

air, and accordingly a formidable and well-paid staff of more than

2000 persons is organized to carry out the delusion to its conclusion.

Luton, Birmingham, and London, afford hints as to what these delusions

may one day end in: that they will proceed in their course, I doubt

not, for, like Macbeth, they are so far involved, that it were safer

to proceed than to back out from their position. This could only have

happened in the land where the greatest of all railways does not pay

the proprietors one shilling of interest on the enormous capital

expended in its construction.

Located by the mouths of the Rhine and Scheld, the ancient Batavians

must early have commenced their struggle with nature. We have no

information from early history of how that struggle began; but one

thing is certain--it was of great antiquity, for in the Morini--the

last of men--Cæsar encountered no fever-stricken, wasted, dejected

people: they must already have discovered the existence of that hidden

enemy, malaria, and taken measures for at least a mitigation of the

evil.[20]
