This electronic edition of Edith A. How's _People of Africa_ was

produced by John Walker in January 2003. It follows the 1921 edition

(the only one of which I am aware) published in London by the Society

for Promoting Christian Knowledge and in New York by the Macmillan

Company. I have corrected two typographical errors in the original

text: "sandstorm" was misspelled as "standstorm" on page 21 (section 1

of chapter III), and "bought" appeared where "brought" was intended on

page 33 (paragraph 3 of section 2 of chapter IV).

Etext Production Notes

This public domain Etext edition of Edith A. How's People of Africa

was prepared by:

If you discover any errors in this Etext, please report them to me by

E-mail. If you're reporting a discrepancy between the Etext and a

modern edition, please include a complete citation of your source.

Upon close examination, most editions contain minor errors and

discrepancies which I've tried to correct in this Etext. These Etexts

are part of the intellectual heritage we share as humans--please help

to make them _perfectly embody_ the authors' legacies to the thousands

of generations and billions of readers whose lives they will enrich.

Beautifully Typeset Etexts

--------------------------

Free Plain Vanilla Etexts don't have to be austere and typographically

uninviting. Most literature (as opposed to scientific publications,

for example), is typographically simple and can be rendered

beautifully into type without encoding it into proprietary word

processor file formats or impenetrable markup languages.

This Etext is encoded in a form which permits it to be both read

directly (Plain Vanilla) and typeset in a form virtually

indistinguishable from printed editions of the work.

To create "typographically friendly" Etexts, I adhere to the following

rules:

1. Characters follow the 8-bit ISO 8859/1 Latin-1 character set.

ASCII is a proper subset of this character set, so any "Plain

ASCII" file meets ths criterion by definition. The extension

to ISO 8859/1 is required so that Etexts which include the

accented characters used by Western European languages may

continue to be "readable by both humans and computers".

2. No white space characters other than blanks and line

separators are used (in particular, tabs are expanded to

spaces).

3. The text bracket sequence:

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>

appears both before and after the actual body of the Etext.

This allows including an arbitrary prologue and epilogue to

the body of the document.

4. Normal body text begins in column 1 and is set ragged right

with a line length of 70 characters. The choice of 70

characters is arbitrary and was made to avoid overly long and

therefore less readable lines in the Plain Vanilla text.

5. Paragraphs are separated by blank lines.

6. Centring, right, and left justification is indicated by

actually so-justifying the text within the 70 character line.

Left justified lines should start in column 2 to avoid

confusion with paragraph body text.

7. Block quotations are indented to start in column 5 and set

ragged right with a line length of 60 characters.

8. Preformatted tables begin with a line which starts in column 3

and contains at least one sequence of three or more spaces

between nonblanks. The table is formatted verbatim until the

next blank line.

9. Text set in italics is bracketed by underscore characters,

"_". These must match.

10. Footnotes are included in-line, bracketed by "[]". The

footnote appears at the point in the copy where the footnote

mark appears in the source text. Footnotes may not be nested

and may consist of only a single paragraph.

11. The title is defined as the sequence of lines which appear

between the first text bracket "<><><>..." and a centred line

consisting exclusively of more than two equal signs "====".

12. The author's name is the text which follows the line of equal

signs marking the end of the title and precedes the first

chapter mark. This may be multiple lines.

13. Chapters are delimited by a three line sequence of centred

lines:

<Chapter number>

--------------------

<Chapter name>

The line of minus signs must be centred and contain three or

more minus signs and no other characters apart from white

space. Chapter "numbers" need not be numeric--they can be any

text.

14. Dashes in the text are indicated in the normal typewritten

text convention of "--". No hyphenation of words at the end

of lines is done.

15. Ellipses are indicated by "..."; sentence-ending ellipses by

"....".

16. Greek letters and mathematical symbols are enclosed in the

brackets "\(" and "\)" and are expressed as their character or

symbol names in the LaTeX typesetting language. For example,

write the Greek word for "word" as:

\( \lambda \acute{o} \gamma o \varsigma \)

and the formula for the roots of a quadratic equation as:

\( x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)

I acknowledge that this provision is controversial. It is as

distasteful to me as I suspect it is to you. In its defence,

let me treat the Greek letter and math formula cases

separately. Using LaTeX encoding for Greek letters is purely

a stopgap until Unicode comes into common use on enough

computers so that we can use it for Etexts which contain

characters not in the ASCII or ISO 8859/1 sets (which are the

7- and 8-bit subsets of Unicode, respectively). If an author

uses a Greek word in the text, we have two ways to proceed in

attempting to meet the condition:

The etext, when displayed, is clearly readable, and

does *not* contain characters other than those

intended by the author of the work, although....

The first approach is to transliterate into Roman characters

according to a standard table such as that given in _The

Chicago Manual of Style_. This preserves readability and

doesn't require funny encoding, but in a sense violates the

author's "original intent"--the author could have

transliterated the word in the first place but chose not to.

By transliterating we're reversing the author's decision. The

second approach, encoding in LaTeX or some other markup

language, preserves the distinction that the author wrote the

word in Greek and maintains readability since letters are

called out by their English language names, for the most part.

Of course LaTeX helps us only for Greek (and a few characters

from other languages). If you're faced with Cyrillic, Arabic,

Chinese, Japanese, or other languages written in non-Roman

letters, the only option (absent Unicode) is to transliterate.

I suggest that encoding mathematical formulas as LaTeX

achieves the goal of "readable by humans" on the strength of

LaTeX encoding being widely used in the physics and

mathematics communities when writing formulas in E-mail and

other ASCII media. Just as one is free to to transliterate

Greek in an Etext, one can use ASCII artwork formulas like:

---------

+ / 2

-b - \/ b - 4ac

x = ------------------

1,2 2a

This is probably a better choice for occasional formulas

simple enough to write out this way. But to produce Etexts of

historic scientific publications such as Einstein's "Zur

Elektrodynamik bewegter K”rper" (the special relativity paper

published in _Annalen der Physik_ in 1905), trying to render

dozens of complicated equations in ASCII is not only extremely

tedious but in all likelihood counter-productive; ambiguities

in trying to express complex equations would make it difficult

for a reader to determine precisely what Einstein wrote unless

conventions just as complicated (and harder to learn) as those

of LaTeX were adopted for ASCII expression of mathematics.

Finally, the choice of LaTeX encoding is made not only based

on its existing widespread use but because the underlying

software that defines it (TeX and LaTeX) are entirely in the

public domain, available in source code form, implemented on

most commonly-available computers, and frozen by their authors

so that, unlike many commercial products, the syntax is

unlikely to change in the future and obsolete current texts.
