A uniform space X is said to be uniformly locally connected if given any entourage U there exists an entourage VU such that V[x] is connected for each xX. It is said to have property S if given any entourage U, X can be written as a finite union of connected sets each of which is U-small.

Based on these two uniform connection properties, another proof is given of the following well known result in the theory of locally connected spaces: The Stone-Čech compactification βX is locally connected if and only if X is locally connected and pseudocompact.
