If you look at that 1881 census page, you can see that there were engineers and firemen in the crew, so it must have been a steamer.
Go to the previous page and you get a lot of information about the ship:
- She is a coasting steamer with schooner rig
- Ship number 54824
- 473 tons
- Registered in Sunderland, where she was on 27 March 1881 before sailing to Harwich
Note also the name of the master, Richardson. That helps in searching for newspaper reports of the ship (search for Druid, Richardson or Druid S or Druid 473).
