fishline

He was apparently very busy doing something with a piece of fishline and a pair of long-legged rubber boots.

So I stands there lookin' him over while he unwraps about four yards of fishline from around the neck of a leather money pouch.

But I always regretted that I did not take along a fishline, just to "throw in" the brook we passed.

He found a fishline in the boat, with a stout hook at the end of it.

A pump that won't work is like a fishline without a hook—good for nothin'.
