History of anthracite coal mining in Pennsylvania coal was being transported annually to Philadelphia using the Schuylkill River (Dublin, Licht, 13) The Wurts brothers, William and Maurice, owned coalfields in the northeastern Pennsylvania anthracite region, but found an unresponsive market in Philadelphia, which was receiving coal from the Schuylkill and Lehigh routes. They saw business potential in finding a connection route between anthracite fields and the New York City market, and so they had the Delaware and Hudson Canal Company incorporated in 1823 (Sciaky, 275-6). The D&H Company built a canal system across parts of the Delaware and Hudson Rivers that stretched from Honesdale, PA to Rondout,
Anthracite budgerigar mutation just one Anthracite allele correspond to the splits of recessive mutations. A single Anthracite factor has a similar effect to the Dark mutation, causing a Skyblue to become Cobalt in appearance - as was suspected with the English Grey. In fact, the similarity of the Anthracite to the English Grey is striking. The description is virtually identical, and the cobalt appearance of a Skyblue with a single Anthracite factor is exactly what was suspected for the English Grey. The interaction of the Anthracite and Dark budgerigar mutations has not yet been investigated. It is expected that a combination of the
