noun. The use of a jag-bolt to secure or fasten something; the insertion of a jagged or serrated bar, bolt, or shaft in a casting, by casting the metal around it.

verb. Present participle of jag.

"It is not an eminently ideal or sportsmanlike sort of fishing, this "jagging," but it possesses a marvellous enjoyment and fascination for the youth of ten, and older people as well; for a full-grown salmon is a powerful fellow, and his big, fluke-like tail enables him to make a terrific rush when under the influence of terror or when chasing his prey."
