These are only lines, no bell.

Segment from illustration by Henry Holiday to Lewis Carroll's The Hunting of the Snark (1876).

In Lewis Carroll's, Henry Holiday's (and Joseph Swain's) illustrations to The Hunting of the Snark, there is a bell in all but two illustrations. You find it even on the front cover and the back cover. The left side of an illustration without a clearly recognizable bell is shown above. It has been drawn by Holiday and cut into a woodblock by Swain. Where is the bell (if there is any)?

(The Bellman's map is the second exception. There is no bell either. But that illustration hasn't necessarily been made by Henry Holiday. And neither did Joseph Swain sign that map. A typographer could have made it.)
