Abstract. For even integers
$k\geqq4$, let
$\varphi_k(X)$ be the separable rational polynomial that encodes the j-invariants of non-elliptic zeroes of the Eisenstein series Ek for the modular group SL
$(2,{Bbb Z})$. We prove Kummer-type congruence properties for the
$\varphi_k$ and, based on extensive calculations, make observations about the Galois group, the discriminant, and the distribution of zeroes of
$\varphi_k(X)$.
