\section{Introduction}
Although it has been around for over a century, margarine was not
always the preferred tablespread in the United States. In 1930, per
capita consumption of margarine was only 2.6 pounds (vs. 17.6 pounds
of butter). Times have changed for the better, though (if you're a
margarine manufacturer, that is). Today, per capita consumption of
margarine in the United States is 8.3 pounds (including vegetable
oil spreads) whereas butter consumption is down to about 4.2 pounds.
Furthermore, as shown in Figure \ref{frontier}, it is always butter,
not margarine, that is traded off against guns. This leads to the announcement of our result.
\begin{theorem}
\label{marg-butt-th}
In a reverse dictionary, $(\mbox{\bi marg}\succ\mbox{\bi butt\/}\; \land\;
\mbox{\bi arine}\succ\mbox{\bi er})$.
Moreover, continuous reading of a compact subset of the dictionary
attains the minimum of patience at the moment of giving up.
\end{theorem}
The proof will be given in the e-companion to this paper.

\section{Motivation}
Margarine or butter? According to the website of the
%%%National Association of Margarine Manufacturers (2005)
\cite{namm}, ``Despite the
recommendations of health professionals and leading health
organizations to choose margarine, many consumers are confused.''
But whether or not they are confused, consumers are voting with
their pocketbooks. The
%%%American Butter Institute (2005)
\cite{abi}, whose
slogan is ``Things are better with butter!'', presents many tempting
recipes on its website, but also reports declining sales in its
marketing releases.
\begin{hypothesis}
Things are better with butter.
\end{hypothesis}
Indeed, even though a reputed chain email letter claims that margarine is ``but
one molecule from being plastic''
%%%(BreakTheChain.org)
\citep{btc},
American consumers appear to be
sliding away from butter. Given this trend, a historical review of
margarine is in order.
\begin{lemma}
Many consumers are confused.
\end{lemma}
\begin{lemma}
Whether or not the consumers are confused, they are voting with
their pocketbooks.
\end{lemma}
\begin{proposition}
American consumers are sliding away from butter.
\end{proposition}
\section{Historical Timeline}
The following are milestones in the history of margarine as
reported by the
%%%National Association of Margarine Manufacturers (2005b)
\cite{namm2}.
Note that they have been transcribed verbatim here, which
is generally bad practice. Even if the material is explicitly
indicated as a quotation, having this much content from another
source will almost certainly result in rejection of the paper for
lack of originality.
But if not called out {\em as a quotation}, lifting even a single
sentence (or less) from another source is plagiarism, even if the
source is cited. Plagiarism is a very serious offense, which will
not only lead to rejection of a paper, but will also bring more
serious sanctions, such as being banned from the journal,
notification of your dean or department chair, etc. So don't do it!
There are many on-line resources to help determine what constitutes
plagiarism and how to avoid (see, e.g., CollegeBoard.com). But the
simplest rule to follow is ``when it doubt, call it out.'' That is,
make very plain what comes from other sources, in properly cited
word-for-word quotations or paraphrases.
\section{1800s}
\begin{quotation}
\begin{description}
\item[\bf 1870] Margarine was created by a Frenchman from Provence,
France -- Hippolyte M\`ege-Mouriez -- in response to an offer by
the Emperor Louis Napoleon III for the production of a satisfactory
substitute for butter. To formulate his entry, M\`ege-Mouriez used
margaric acid, a fatty acid component isolated in 1813 by Michael
Chevreul and named because of the lustrous pearly drops that reminded
him of the Greek word for pearl -- margarites. From this word,
M\`ege-Mouriez coined the name margarine for his invention that
claimed the Emperor's prize.
\item[\bf 1873] An American patent was granted to M\`ege-Mouriez who
intended to expand his French margarine factory and production to
the United States. While demand for margarine was strong in northern
Europe and the potential equally as promising in the U.S.,
M\`ege-Mouriez's operations nevertheless failed and he died obscurely.
\item[\bf 1878] Unilever began manufacturing margarine in Europe.
\item[\bf 1871-73] The U. S. Dairy Company in New York City began
production of "artificial butter."
\item[\bf 1877] State laws requiring identification of margarine were
passed in New York and Maryland as the dairy industry began to feel
the impact of this rapidly growing product
\item[\bf 1881] Improvements to M\`ege-Mouriez's formulation were made;
U.S. Dairy created a subsidiary, the Commercial Manufacturing Company,
to produce several million pounds annually of this new product.
\item[\bf 1885] When a court voided a ban on margarine in New York,
dairy militants turned their attention to Washington, resulting in
Congressional passage of the Margarine Act of 1886. The Act imposed
a tax of two cents per pound on margarine and required expensive
licenses for manufacturers, wholesalers and retailers of margarine.
President Grover Cleveland, from the dairy state of New York, signed
the law, describing it as a revenue measure. However, the 1886 law
failed to slow the sale of margarine principally because it did not
require identification of margarine at the point of sale and
margarine adversaries turned their attention back to the states.
\item[\bf 1886] More than 30 manufacturing facilities were reported to
be engaged in the production of margarine. Among them were Armour
and Company of Chicago and Lever Brothers of New York. Seventeen
states required the product to be specifically identified as
margarine. Various state laws to control margarine were passed in a
number of states, but were not enforced. Later that year, New York
and New Jersey prohibited the manufacture and sale of yellow-colored
margarine.
\end{description}
\end{quotation}
\section{1900s}
\subsection{Before the End of WWII}
\begin{quotation}
\begin{description}
\item[\bf 1902] 32 states and 80\% of the U.S. population lived under
margarine color bans. While the Supreme Court upheld such bans, it
did strike down forced coloration (pink) which had begun in an
effort to get around the ban on yellow coloring. During this period
coloring in the home began, with purveyors providing capsules of
food coloring to be kneaded into the margarine. This practice
continued through World War II.
\item[\bf 1902] Amendments to the Federal Margarine Act raised the tax
on colored margarine five-fold, but decreased licensing fees for
white margarine. But demand for colored margarine remained so
strong, that bootleg colored margarine flourished.
\item[\bf 1904] Margarine production suffered and consumption dropped
from 120 million pounds in 1902 to 48 million.
\item[\bf 1910] Intense pressure by competitors to keep prices low and
new product innovations, as well as dairy price increases, returned
production levels of margarine back to 130 million pounds. The
Federal tax remained despite many efforts to repeal it, but
consumption grew gradually in spite of it.
\item[\bf 1920] With America's entry into World War I, the country began
to experience a fat shortage and a sharp increase in the cost of
living, both factors in driving margarine consumption to an annual
per capita level of 3.5 pounds.
\item[\bf 1930] The Margarine Act was again amended to place the Federal
tax on naturally-colored (darkened with the use of palm oil) as well
as artificially-colored margarine. During the Depression dairy
interests again prevailed upon the states to enact legislation
equalizing butter and margarine prices. Consumers reacted and
consumption of margarine dropped to an annual per capita level of
1.6 pounds.
\item[\bf 1932] Besides Federal taxes and licenses, 27 states prohibited
the manufacture or sale of colored margarine, 24 imposed some kind
of consumer tax and 26 required licenses or otherwise restricted
margarine sales. The Army, Navy and other Federal agencies were
barred from using margarine for other than cooking purposes.
\item[\bf 1941] Through production innovations, advertising and improved
packaging, margarine consumption regained lost ground. A Federal
standard was established recognizing margarine as a spread of its
own kind. With raised awareness of margarine's health benefits from
a 1941 National Nutrition Conference, consumers began to take notice
of restrictions on margarine that were keeping the product from them
and artificially inflating the price.
\item[\bf 1943] State taxes on margarine were repealed in Oklahoma. The courts
removed color barriers in other states shortly after World War II (see \citealt{tjp}).
\end{description}
\end{quotation}
\subsection{After the End of WWII}
\begin{quotation}
\begin{description}
\item[\bf 1947] Residual war shortages of butter sent it to a dollar a pound
and Margarine Act repeal legislation was offered from many politicians.
\item[\bf 1950] Some of the more popular brands prior up until now were Cloverbloom,
Mayflower, Mazola, Nucoa, Blue Plate, Mrs. Filbert's, Parkay,
Imperial, Good Luck, Nu-Maid, Farmbelle, Shedd's Safflower,
Churngold, Blue Bonnet, Fleischmann's, Sunnyland and Table Maid.
\item[\bf 1950] Margarine taxes and restrictions became the talk of the country.
Finally, following a significant effort by the National Association
of Margarine Manufacturers, President Truman signed the Margarine
Act of 1950 on March 23 of that year.
\item[\bf 1951] The Federal margarine tax system came to an end. Pre-colored
margarine was enjoyed by a consumer also pleased with lower prices.
Consumption almost doubled in the next twenty years. State color
bans, taxes, licenses and other restrictions began to fall.
\item[\bf 1960s] The first tub margarine and vegetable oil spreads were
introduced to the American public.
\item[\bf 1967] Wisconsin became the last state to repeal restrictions on
margarine \citep{w}.
\item[\bf 1996] A bill introduced by Rep. Ed Whitfield would signal an end
to the last piece of legislation that adversely affects the sale of
margarine. Currently, federal law prohibits the retail sale of
margarine in packages larger than one pound, as well as detailed
requirements regarding the size and types of labeling of margarine
and a color requirement. This new legislation would remove these
restrictions from the Federal Food, Drug, and Cosmetic Act (FFDCA).
Rep. Whitfield's bill, the Margarine Equity Act, is part of HR 3200,
the Food and Drug Administration (FDA) reform package and addresses
dated requirements that are not applicable to the marketplace.
\item[\bf 1998] 125th anniversary of the U.S. patent for margarine

\section{Proof of Theorem \ref{marg-butt-th}.}
To avoid confusion, theorems that we repeat for readers' convenience
will have the same appearance as when they were mentioned for the first
time. However, here they should be coded by \verb+repeattheorem+ instead
of \verb+theorem+ to keep labels/pointers uniquely resolvable. Other predefined theorem-like
environments work similarly if they need to be repeated in what becomes the \mbox{e-companion.}
\begin{repeattheorem}[Theorem 1.]

\subsection{Proof of the Main Result}
\proof{Proof of Theorem 1.} The first statement is a conseqence of

\section{Conclusions}
Since we didn't do anything original in this paper, we don't
actually have any conclusions. But we have to have a conclusions
section in here, so we're writing one. Don't the margins look good?
How about those section headings? Pretty snappy, eh?
However, just because we didn't produce any results, doesn't mean
that there isn't good butter re-search going on out there. Many
researchers
%%%(e.g., Tholstrup et al. 2006, Hodson et al. 2001)
(e.g., \citealt{trbn}, \citealt{h})
continue to push out the envelope of our understanding of butter and
its health effects. Others are focusing on related products, such as cheese
%%%(see, e.g., Fontecha et al. 2006).
(see, e.g., \citealt{fo}).
Still others are
investigating the linguistic
%%%(Feldman and Schwan 1990)
\citep{fs}
and sociopolitical
%%%(Geisel 1984)
\citep{g}
implications of butter. So butter
remains a hot research area with lots of potential for the future.
All the potential in the world won't amount to much if research
isn't cited correctly, though. Make sure you include complete
citation information for your references, including publication or
re-trieval dates for website citations, publication year and volume
and issue numbers for journal articles, publisher names and
