- n. A line fastened to the valve at the top of a balloon, by pulling which the valve is opened.
Sorry, no etymologies found.
Perhaps he thought that was enough, for he pulled the valve-line, and a few minutes later alighted in a field two miles from his starting-place, and the home of one of the Englishmen.
In this position his eyes were directed to Mr Coxwell, who did not at first observe the state of his companion, in consequence of his having had to ascend into the ring of the balloon to disentangle the valve-line, which had become twisted.
Presently I see Mr Coxwell, whose eye has been continually watching the balloon, pass his fingers over the valve-line, as if in readiness to pull the cord.
