[Tex/LaTex] indentation of enumerate items inside quotation

#enumerateindentation

I have the following LaTeX code:

\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\begin{document}
This is some text. This is still more text. Here is a few more words.
\begin{quotation}
\begin{enumerate}
\item First item
\item Second item
\item Third item
\end{enumerate}
\end{quotation}
\end{document}

I would like to create the following:

This is some text. This is still more text. Here is a few more words.

    1. First item
    2. Second item
    3. Third item

But instead I end up with this:

This is some text. This is still more text. Here is a few more words.

     1. First item
 2. Second item
 3. Third item

That is, the first item is being more indented than the others. How could this behaviour be changed? I suppose I could use the enumitem package, but unfortunately could not figure out how to do it.

Thanks in advance for any assistance you can provide.

With warmest regards,

\mbox{}\vspace{-\baselineskip}
\begin{enumerate}

works, (hard to justify the behaviour of nested list environments really, but impossible to change now). You see similar effects if you use enumerate in theorem environments which are similarly usually list environments.
