Since “spur” is not mentioned in the text I assume you mean “spar”. That’s difficult because in this case “spar” is a technical term:
“A stout pole such as those used for masts, etc.; a mast, yard, boom, gaff, or the like.”
Just to add to @Deahna’s info: spar is also
a. a mineral and
b. a verb “to spar” = making attacking and defending movements (seen in box sports where a “sparring partner” helps you train).
