The museum’s frog info site is sponsored by Alcoa, a company more responsible for the destruction of Hills frog habitat than any other. I went to confirm a childhood memory, and realised those tadpoles and froglets and juvenile frogs we stole from their homes under the spillway of Churchman’s Brook Dam, or from creeks or banks of those creeks downstream that still ran unhindered by engineering, to lift and bottle and translocate to our garden pond (a kind of liberty, we imagined: an old concrete double-sided washtub with its dividing wall smashed through and plughole cemented and buried, so soil and grass lapped its banks), were already or would become Moaning Frogs and Motorbike Frogs. Both defined by their noise, and not their psychologies or composition. We’d observe tadpole conversions. Alcoa mines bauxite. Aluminium comes from bauxite. Each act of extraction is lexical and contrite as donation. No E. M. Forster requirements for narrative are required to tell this story. Its outcomes. Though the sensation of frogskin on your skin was more than citation. And it is with more than détournement that we touch aluminium.
