It is shown that if $n^{-1}\sum ^{n-1}_{r=0} T^r1$ converges pointwise to a continuous limit, then the convergence is uniform on $X$.(ii) An example is given of a Choquet simplex $K$ and a positive linear operator $T$ on the space $A(K)$ of continuous affine real-valued functions on $K$, such that\begin{}{\rm inf}\lbrace (T^n1)(x) : n\ge \rbrace < 1\end{}for each $x$ in $\partial _\ell K$, but $\Vert T^n1\Vert $ does not converge to 0.
