ABSTRACT
Few agriculture books achieve the status of
‘classic’. F. H. King’s book Farmers of Forty
Centuries or Permanent Agriculture in China,
Korea and Japan was privately published in
Wisconsin, USA, in 1911. The book had an in-
auspicious start, and the longevity and acclaim
that this book has since achieved must have
been, then, barely conceivable. The author was
dead, the book was incomplete, and there was
no commercial publisher. Yet through a com-
bination of perhaps luck and circumstance the
book was ‘resurrected’ in 1927 by a London
publisher, Jonathan Cape, who then kept it in
print for more than two decades. The London
issue of King’s book was favorably cited in the
1930s and 1940s by leading agriculture and or-
ganic agriculture writers including: Lord North-
bourne, Eve Balfour, Viscount Lymington, Al-
bert and Louise Howard in Britain; Ehrenfried
Pfeiffer in Switzerland; Jerome Rodale in the
USA; and Stanton Hicks in Australia. These
endorsements served to entrench King’s book
as a ‘classic’. Jerome Rodale reintroduced the
book to a US audience with an edition published
by his Organic Gardening Press, c.1949. King’s
book arose out of his discontent with the views
promulgated by the US Department of Agricul-
ture (USDA), he differentiated the Asian agri-
culture he encountered as ‘permanent agricul-
ture’, he provided a detailed account of the an-
cien régime organic agriculture of China, Korea
and Japan, he called for a “world movement” for
agricultural reform, and his book was been
taken as a validation of the principles of organic
agriculture. At least twenty six impressions of
Farmers of F orty Centuri es hav e been pu blished
in the past century; ten of these appeared dur-
ing the first nine decades, while 16 have ap-
peared in the past decade.

1. INTRODUCTION
In his 1940 manifesto of organic farming, Look to the
Land, Lord Northbourne described Farmers of Forty
Centuries as a “classic” [1] and as “that great book by
Professor King et al. Farmers of Forty Centuries, a book
which no student of farming or social science can afford
to ignore” [1]. Eve Balfour in her 1943 book The Living
Soil followed Northbourne’s lead and also described
Kings book as a “classic” [2]; she wrote that: “By ad-
hering to this principle [of composting] the Chinese
peasant has intensively and continuously cropped his
soil without loss of fertility for forty centuries” [2].
Despite the enthusiasm and endorsement of North-
bourne, Balfour and others, the book Farmers of Forty
Centuries or Permanent Agriculture in China, Korea and
Japan did not appear destined for greatness when it first
appeared in 1911 [3]. An agriculture book that is a clas-
sic is something rare, and for this bo ok, written by F. H.
King, the beginning must have seemed, at the time, even
more inauspicious than most. There was no commercial
publisher, the author was dead, and the manuscript was
incomplete. In his lifetime, King was neither a cele-
brated writer nor a prominent public figure. A few years
prior he had made an acrimonious departure from the US
Department of Agriculture. Added to these unlikely
recommendations, Farmers of Forty Centuries was a
book about the an cient practices of the Orient and it was
offered into the US market which was focussed on, and
seemingly mesmerised by, Occidental techno-fixes.
The concept of ‘permanent agriculture’ was, at least
partly, the outcome of an internecine war, between the

Bureau of Soils of the United States Department of Ag-
riculture (USDA) and two US professors of agriculture.
Cyril George Hopkins (1866-1919) was Professor of
Agronomy at the University of Illinois, and Franklin
Hiram King (1848-1911) was Professor of Agricultural
Physics at the University of Wisconsin. King took up the
position of Chief of the Division of Soil Management in
the Bureau of Soils of the USDA. For King it was an
unhappy appointment, his tenure was brief (1902-1904),
and his departure was acrimonious [4].
King’s research findings clashed with the prevailing
USDA orthodoxy being promulgated by Milton Whitney,
the chief of the USDA Bureau of Soils. Whitney ulti-
mately forced King’s resignation [4]. Whitney vetoed
the publication of three of King’s research papers during
King’s brief stint at the USDA [4-6]. In 1904, a con-
temporary of King and Hopkins, E. W. Hilgard, accused
the USDA’s censorship of soil science as a “return to
medievalism” and accused it of “a deliberate attempt to
suppress the truth” [5]. Hilgard called on scientists to
“protest against the d ictation of official orthodox science
of any kind, from headquarters at Washington” [5].
King objected to Whitney and Cameron’s theory,
published in 1903, that the nutrients in soil will last in-
definitely without replenishment [7], and to Whitney’s
1906 proposition that manures work by offsetting the
“toxic excreta” of plant roots [8]. Whitney boasted that
USDA Soil Bulletins were used as text books in US ag-
ricultural colleges [9]. The times were described as “tu-
multuous” [6] and as occasioning “some extraordinary
invective” [6]; and certainly there was robust disagree-
ment between the professors and the USDA.
Hopkins and King were on a collision cou rse with the
USDA. Hopkins was an articulate critic and he was
scathing of the USDA: “the erroneous teaching so
widely promulgated by the federal Bureau of Soils is
undoubtedly a most potent influence against the adop-
tion of positive soil improvement in the United States,
because it is disseminated from the position of highest
authority. Other peoples have ruined other lands, but in
no other country has the powerful factor of government
influence ever been used to encourage the farmers to
ruin their lands” [10].
Hopkins, in 1910, denounced the USDA: “Whitney
and Cameron have revived Decandolle’s theory of toxic
excreta from plant roots, in support of another more
radical theory announced by them, to the effect that soils
do not wear out or become depleted by cultivation or
cropping. While this theory is advanced with no ade-
quate found ation and in direct oppo sition to practical ex-
perience and to so many known facts of mathematics,
chemistry, and geology, that it is in itself quite unworthy
of further consideration, the fact is that it has been
promulgated by Professor Whitney as Chief of the
United States Bureau of Soils, and by Doctor Cameron,
as the chief chemist of the same Bureau; and, conse-
quently, it cannot be ignored” [9].
Hopkins endorsed King at the expense of the USDA:
“It appears, however, that the conclusions of Whitney
and Cameron even concerning the nonrelationship be-
tween crop yields and water-soluble plant food are
wrong”. Professor F. H. King, a most careful investiga-
tor of the highest integrity, as the result of two years’
experiments, including many determinations made dur-
ing the crop season, before severing his connection with
the Bureau of Soils, was led to [contrary] conclu-
sions” [9 ].
The enduring outcomes of this academic feud with the
USDA included King’s visit to the Orient, in 1909, and
four books on ‘permanent agriculture’ from 1910 to
1913 (Ta ble 1). The first of those books was Hopkins’
Soil Fertility and Permanent Agriculture [9] (Plate 1) in
which he vented his frustration with the USDA ortho-
doxy of the day, and praised King.
Although King’s book was not published until 1911,
Hopkins’ 1910 book commented (correctly) that King
had “recently visited the Orient” and he reported some
of King’s results in his own book [9]. The three works
by Hopkins were clearly targeted at different audiences
and they were written in quite different styles. After Soil
Fertility and Permanent Agriculture (649 pages, 1910),
came The Story of the Soil (362 pages, 1911), and The
Farm That Won't Wear Out (80 pages, 1913). All three
books championed the concept of permanent agriculture.
In The Farm That Won't Wear Out, Hopkins concluded
that: “the intelligent improvement of his soil, in systems
of permanent agriculture, is the most profitable business
in which the farmer and land owner can engage” [11].
Each of Hopkins’ three books found publishers in their
day, but not since, and his three works are now all but
forgotten a common fate of agriculture books written a
century ago.

King is still in print; the 2004 reprint by Dover changed ‘Per-
manent Agriculture’ to ‘Organic Farming’ (right) (Photo: J.
Paull).
Having quit the USDA, King embarked on an eight
month oriental agricultural tour. He arrived in Yoko-
hama in February 1909 and toured extensively in China,
Japan, and, to a much lesser extent, Korea [3,12]. King
died with the book in complete—it lack s the fin al chapter
and hence his conclusions.
In the Introduction to his book, King explains his pro-
ject: “We had long desired to stand face to face with
Chinese and Japanese farmers; to walk through their
fields and to learn by seeing some of their methods, ap-
pliances and practices which centuries of stress and ex-
perience have led these oldest farmers in the world to
adopt. We desired to learn how it is possible, after
twenty and perhaps thirty or even forty centuries, for
their soils to be made to produce sufficiently for the
maintenance of such dense populations … we were in-
structed, surprised and amazed at the conditions and
practices which confronted us whichever way we turned;
instructed in the ways and extent to which these nations
for centuries have been conserving and utilizing their
natural resources” [3].
King foresaw a world movement for agricultural re-
form: “China, Korea and Japan long ago struck the key-
note of permanent agriculture, but the time has now
come when they can and will make great improvements,
and it remains for us and other nations to profit by their
experience, to adopt and adapt what is good in their
practice and help in a world movement for the introduc-
tion of new and improved methods” [3].
Farmers of Forty Centuries was described as a book of
“450 pages, 246 illustrations; Price $ 2.50” [3]. It is a
book of 18 chapters, of which the final one, ‘Message of
China and Japan to the World’, is absent, due to the au-
thor’s death.
2. PUBLISHING, THE FIRST CENTURY
In contrast to Hopkins’ books, which attracted com-
mercial publishers, King’s Farmers of Forty Centuries
were initially privately published by his widow, and the
publisher appears as “Mrs. F. H. King”. The London
publisher, Jonathan Cape, rescued King’s book from
looming oblivion and successfully republished Farmers
of Forty Centuries in London in 1927 [13].
Between the time when King’s book first appeared in
1911 in the USA, and its reapp earance in Britain in 19 27,
there had been some profound changes in the practice of
agriculture. Fritz Haber and Carl Bosch in Germany had
successfully demonstrated their method of ‘fixing’ ni-
trogen from the air, in 1909, and this was rapidly and
successfully commercialised on an industrial scale. The
‘Haber-Bosch Process’ ushered in an era of cheap syn-
thetic nitrogenous fertilisers for farmers [14]. By the
time Jonathan Cape took up Farmers of Forty Centuries
there was a developing questioning and discontent at this
input-intensification of farming. Rudolf Steiner’s Agri-
culture Course held in 1924 at Koberwitz (now Ko-
bierzyce, Poland) was an early response to the wave of
change sweeping agr iculture [15]. The impuls e of Steiner’s
course gained momentum and Ehrenfried Pfeiffer pub-
lished Bio-Dynamic Farming and Gardening in 1938,
with editions appearing in five languages [16].
The Jonathan Cape issue of Farmers of Forty Centu-
ries appeared in Britain at a time when agriculture was
under scrutiny and discussion, and further Jonathan Cape
impressions followed in 1933, 1939, and 1949. In the
USA, almost four decades elapsed from the first publica-
tion Farmers of Forty Centuries until Jerome Rodale
reissued the book under his imprint ‘Organic Gardening
Press’, Emmaus, PA, circa1949. By this time, Pfeiffer
had moved from Switzerland to the US, and he was ac-
tively promoting biodynamic agriculture, Northbourne
had introduced the term ‘organic farming’ [17], and Ro-
dale had launched the periodical Organic Farming and
Gardening [18]. The foundational books of the biody-
namic and organic movements, Pfeiffer’s Bio-Dynamic
Farming and Gardening, and Northbourne’s Look to the
Land, both referred to the Jonathan Cape imprint of
King’s Farmers of Forty Centuries.
The Waste Products of Agriculture, pub lished in 1931
by Howard and Wad, owes a debt to King’s Farmers of
Forty Centuries. The Howard & Wad title echoes the
title of King’s Chapter IX: “The Utilization of Waste”
[3]. The opening sentence of Howard & Wad is an echo
of King: “The maintenance of fertility of the soil is the
first condition of any permanent system of agriculture”
[19]. King’s photograph of a compost pit [3] and How-
ard and Wad’s photographs [19] are strikingly similar.
Howard & Wad also cited “Wagner, W. Die Chinesische
Landwirtschaft [trans: Chinese Agricultural], Berlin,
1926” [19]. Of the so called ‘Indore method’ of com-

posting, Howard’s wife, Louise Howard, stated that: “it
seemed obvious to try out the methods which had been
known in China for over four thousand years” [20], and
she declared that: “We cannot do better than what the
Chinese do” [20]. Northbourne referred to methods of
practicing organic farming, describing one category:
“The second category I call the Indore-Hunza-Chinese
method - Chinese for short” [21].
Viscount Lymington cited King’s book in his 1938
book Famine in England [22], as did the authors of the
developing biodynamics and organics literature. Advo-
cates citing Farmers of Forty Centuries included: Ehren-
fried Pfeiffer in 1938 in Switzerland [23]; Eve Balfour in
1943 in England [2]; Stanton Hicks in 1945 in Australia
[24]; and Jerome Rodale in 1945 in USA [25]. The edi-
tion of Farmers of Forty Centuries to which Pfeiffer,
Northbourne, Balfour, Hicks, Rodale, and the Howards
referred, was the UK reprint by Jonathan Cape [13]
(none cited the first edition).
At least 26 impressions or editions of Farmers of Forty
Centuries have appeared in English under a variety of
imprints over the century since the first edition of 1911
(Figure 1). There have been three decades in which no
new editions appeared (Figure 1). The decade of most
publishing activity is the last decade (2001-2010) (Fig-
ure 1); and the year of greatest activity has been 2010
with five new issues (Figure 2). In the 1920s and the
1930s Jonathan Cape had the field to themselves, and
this persisted until King was finally republished in the
USA by Organic Gardening Press (now Rodale Press) in
about 1949. Rodale Press has since then issued impres-
sions in 1972, 1973, 1978, and 1990.
In March 2004, Steve Solomon and Charles Al-
dorondo uploaded a digital file of Farmers of Forty
Centuries to Project Gutenberg (www.gutenberg.org)

as EBook #5350. This made King’s text freely available
and searchable to all those with internet access, and it
remains thus today. From 1990 to 2004 there had been
no new hardcopy editions; then, coinciding with the re-
lease of the digital Farmers of Forty Centuries, Dover
also published in March 2004, their ill-considered reti-
tled edition as: Farmers of Forty Centuries: Organic
Farming in China, Korea and Japan. This redacted title
has nothing to recommend it—other than as a dubious
marketing ploy. It is anachronistic to redact ‘permanent’
to ‘organic’ since the term ‘organic agriculture’ had no
currency until Northbourne introdu ced the term ‘organic
farming’ in 1940, and it is neither a term that King used
nor would have recognised. Dover did not redact any of
the body of King’s text, so ‘organic’ stands alone on the
cover of their book as a misleading anachronism.
After the Gutenberg and Dover Farmers of Forty
Centuries appeared in 2004, there has been a veritable
‘explosion’ of impressions with more new impressions
and editions of King being published in the past decade
than in the previous nine decades. Since the Dover edi-
tion, there have been editions by: Kessinger Publishing
(2004); Indy Publish (2005); The Press at Toad Hall
(2005); Biblio Bazaar (2007); Bastian Books (2008);
Biblio Life (2008); Global Oriental (2008); Icon Group
International (2009); Pranava Books (2009); Textstream
(2010); Gener al Books LLC (2010); ValdeBooks (2010);
HardPress Publishing (2010); and Nabu Press (2010).
3. DISCUSION AND CONCLUSIONS
The publishing history of Farmers of Forty Centuries
has been uneven, but it is now enjoying a ‘golden era’.
In the decade just passed, sixteen separate publishers
offered editions of King’s book. This new proliferation
has coincided with technological advances and opportu-
nities including the development of print on demand
(POD) technol ogi es for book producti o n, faster scanners,
opportunities for short run publishing, online interna-
tional bookshops, for example Amazon.com, and devel-
oping opportunities for order taking and fulfilment, all
facilitated by the lapse of copyright and by the growing
interest in organic agriculture.
With the proliferation of Farmers of Forty Centuries

in digital and print formats, its future now seems secure.
The ‘rescue’ of the book by the London publisher Jona-
than Cape in 1927 was a resur rection for the book wh ich
was, by then, all but forgotten. The consensus of en-
dorsement of the book by the early organic agriculture
pioneers was itself an endorsement of the decision by
Jonathan Cape to republish, and it was the London edi-
tions that they referenced, rather than the original.
Although the book Farmers of Forty Centuries con-
tinues to gain currency, its defining meme, ‘permanent
agriculture’, has gained little traction. The 1929 book
Tree Crops: A Permanent Agriculture [26] is a rare ex-
ample which has, since King and Hopkins, used the term
as a defining element of its narrative. ‘Permanent agri-
culture’ was appropriated and contracted to generate the
neologism ‘permaculture’ which appeared in the 1978
Tasmanian book of Mollison & Holmgren: Permaculture
1: A perennial agriculture system for human settlements
[27]. The contraction is co nfirmed in the title of the sec-
ond volume: Permaculture Two: Practical design for
town and country in permanent agriculture [28].
The book Farmers of Forty Centuries remains of in-
terest for at least four reasons. Firstly was the timing.
King’s championing of soil husbandry was contempora-
neous with the development of synthetic fertilizer tech-
nology by Haber and Bosch [29]. King’s book preceded
the chemical industry’s development of synthetic pesti-
cides, and the US seizure of German chemical patents
[30]. It was remarkably prescient coming at a time prior
to the, then, forthcoming immanent and major upheavals
in farming practice, including the transformation of ag-
riculture by the chemical industry.
Secondly, King’s book recorded, with an eye for de-
tail, and with precision augmented by statistics, the prin-
ciples and practice of what we can now describe as an-
cien régime organic agriculture. His book described ag-
ricultural practices across three populous countries
which were self sufficient in food and had been feeding
large populations, from the same soil, for millennia. Or-
ganics advocates have viewed it as an validation of their
methods and it remains of interest to organics scholars
because of its influence, its persistence, and its testi-
mony.
Thirdly, King, as well as Hopkins, chose a term, in
their case ‘permanent’, that qualified ‘agriculture’, and
thereby differentiated the practice of ‘permanent agri-
culture’ from ‘orthodox agriculture’ as preached by the
USDA. The term arose from a conflict, a clash of ide-
ologies, and signalled a cleavage of the territory of agri-
cultural theory and practice into different camps; it a
cleavage which remains to this day. As a distinguishing
term, ‘permanent’, was the first of many such distin-
guishing terms for alternative agricultures. ‘Permanent
agriculture’ emerged in response to, and out of a conflict
with, the USDA’s view of agriculture. There is the par-
allel with ‘organic agriculture’ which emerged, framed
as a contest, three decades later as Northbourne’s “or-
ganic versus chemical farming” [1]. ‘Permanent’ was a
precursor to ‘organic’, the term which has, in the interim,
become the dominant descriptor (and meme) to describe
non-orthodox, alternative agriculture.
Fourthly, King called for a “world movement” [3] to
introduce and develop permanent agriculture practices.
He noted that “China, Korea and Japan long ago struck
the keynote of permanent agriculture it remains for
us and other nations to profit by their experience”. The
call for a “world movement” o alternative agriculture
eventually manifested in France, in 1972 as the Interna-
tional Federation of Organic Agriculture Movements
(IFOAM) [31].
As China is now adopting organic agriculture on a
grand scale [32] there are increasing opportunities to
compare, across the divide of a century, places and prac-
tices that were documented by King. He described, for
example, Chongming Island (King spells it ‘Chungming’)
which is now increasingly adopting modern organic ag-
riculture practices [33].
King’s book has a special place in the canon of agri-
cultural writers in general and organic farming in par-
ticular, and Farmers of Forty Centuries has earned its
standing as a ‘classic’. In describing, with the eye of a
scientist, an agricultural world that has all but disap-
peared, the work offers an accessible record of agricul-
tural practices of increasing interest as the world faces
the challenges of novel and contested agricultural tech-
nologies.
