A slab of pale grey-green to cream amphibole with long, parallel fibres running the length of the piece and dark flecks on one face, kept with its original label in a plastic sleeve. The printed label of Ward's Natural Science Establishment, Inc., Rochester, N.Y. reads "Dana 338, No. 120, Amphibole, var. Asbestus, Monoclinic", with the formula Ca2(Mg,Fe)5Si8O22(OH)2 and the locality Bozeman, Montana. That formula is the tremolite-actinolite series, the amphiboles behind tremolite and actinolite asbestos; Ward's sold reference specimens like this to schools and collectors.
