The Wilts & Berks magazine ‘Dragonfly’ was named after a boat, here is an extract from magazine issue #1 dated November 1977:
"Our journal is named after the steam inspection launches of HR de Salis, deputy chairman of F.M.C at the time. The second launch had many connections with W & B, being photographed in the locks at Ardington and Latton Basin. It was built at Abingdon in 1895 and its engine boiler built at Wantage"
A set of glass slides held by Swindon Library shows that ‘Dragonfly’ had passed along the Wilts & Berks Canal and North Wilts Canal in 1895, see photos below, these slides feature in Swindon Library’s ‘Flickr Collection, they don’t show ‘Dragonfly’ to the south-west of Swindon, although there is proof that it travelled along the entire canal.
H R de Salis’ book called the ‘Chronology of Inland Navigation’ was published in 1897, and at the back of the book Mr de Salis listed the journeys he had made on the inland waterways, perhaps to show his extensive knowledge. The table shows that ‘Dragonfly’ traversed the Wilts & Berks and North Wilts canals up to three times, as shown in the table below from his ‘Chronology’ book:
