  We explicitly write down the Eisenstein elements inside the space of modular
symbols for Eisenstein series with integer coefficients for the congruence
subgroups $\Gamma_0(N)$ with $N$ odd square-free. We also compute the winding
elements explicitly for these congruence subgroups. This gives an answer to a
question of Merel in these cases. Our results are explicit versions of the
Manin-Drinfeld Theorem [Thm. 6]. These results are the generalization of the
paper [1] results to odd square-free level.
