Abstract: Almost local finiteness is introduced. The class of all spaces with a $\sigma$ -almost locally finite base is an intermediate class between that of free -spaces and that of ${M_1}$ -spaces. The class is countably productive, hereditary and the closed image of a space in the class is ${M_1}$ .
