Autograph letter signed by engineer George Willoughby Hemans dated 1866

HEMANS, George Willoughby (1814-1885). Autograph Letter Signed to Lt. Col. Manby concerning work placements for his and Sir Joseph Bazalgette's sons with George Robert Stephenson.
 
Single sheet folded, written on first and final pages, on printed headed paper of "1 Westminster Chambers, Victoria Street, S.W.", dated 28 December 1866. Old folds, a few trivial marks and light handling wear; very good overall.
 
A Victorian engineering-network letter linking three major nineteenth-century engineering names. Hemans writes to Lt. Col. Manby that "Bazalgette and I are both anxious to put our sons together into an engine works for a few months", before asking whether "G. R. Stephenson would let us send them to yours or rather his".
 
The Bazalgette referenced is almost certainly Sir Joseph Bazalgette (1819-1891), chief engineer of London's great sewer and embankment works, while G. R. Stephenson is George Robert Stephenson (1819-1905), prominent civil engineer, nephew of George Stephenson and cousin of Robert Stephenson.  An  engineering related letter connecting Hemans, Bazalgette and Stephenson.
