  We study properties of the semigroup $(e^{-tH})_{t\ge 0}$ on the space $L^
2(\Gamma_X,\pi)$, where $\Gamma_X$ is the configuration space over a locally
compact second countable Hausdorff topological space $X$, $\pi$ is a Poisson
measure on $\Gamma_X$, and $H$ is the generator of the Glauber dynamics. We
explicitly construct the corresponding Markov semigroup of kernels $(P_t)_{t\ge
0}$ and, using it, we prove the main results of the paper: the Feller property
of the semigroup $(P_t)_{t\ge 0}$ with respect to the vague topology on the
configuration space $\Gamma_X$, and the ergodic property of $(P_t)_{t\ge 0}$.
Following an idea of D. Surgailis, we also give a direct construction of the
Glauber dynamics of a continuous infinite system of free particles. The main
point here is that this process can start in every $\gamma\in\Gamma_X$, will
never leave $\Gamma_X$ and has cadlag sample paths in $\Gamma_X$.
