Abstract: In the paper an answer to a problem "When different orders of R(X) (where R
is a real closed field) lead to the same real place ?" is given. We use this
result to show that the space of $\mathbb R$-places of the field
$\textbf{R}(Y)$ (where \textbf{R} is any real closure of $\mathbb R(X)$) is not
metrizable space. Thus the space $M(\mathbb R(X,Y))$ is not metrizable, too.
