Many of Wilding's sculptures concern duality. Works are frequently made from two separate elements. In this sculpture, a cylindrical form, made from two sheets of galvanised steel bolted together, is placed close to a much smaller barrel shaped element, made from oak. The surface of the wooden shape has been worked by hand and is punctured, so that the interior space is slightly revealed. The smaller shape bulges as if inhaling air from either end. As in all Wilding's work, there is a sense of poetic mystery, the suggestion of a concealed inner meaning.
