David Mason’s fifth book of poetry, Sea Salt, explores the ineffable degradation of the surface while the internal core remains intact. The poems use “salt” as an over-riding metaphor to define a world that is slowly being eaten away by time and the elements. The lines in most every poem within this volume are plain-spoken, clear, rhythmically assured and cut to weigh against each other. The voice is confident and employs vivid metaphor to express regret, loss, and joy. Poetry, after time and the elements do their bidding, is what remains.
