Abstract: It is proved that in a free nilpotent Lie algebra there are no nonabelian ideals which are free nilpotent as subalgebras. It is also shown that, for any proper ideal $ S$ of a free Lie algebra $ F$, the quotient of the lower central terms $ {F_m}/{S_m}$ is not finitely generated when $ F \ne {F_2} + S$. If $ F = {F_2} + S,\;F/S$ is finite-dimensional and $ S$ is finitely generated as an ideal in $ F$, then $ {F_m}/{S_m}$ is finitely generated as an algebra for all $ m \geqslant 1$.
