English: This is an English language reproduction that the magazine the Engineer made from an 1830 drawing of the compound steam engine of the tugboat Hercules. It proves that compound steam engines were in effective use for inland navigation by the 1830s. The signatures of Croll, Walter Pearce and a third witness for its authenticity are on the bottom right. |
