The skin of the eel, when properly prepared, is not excelled for toughness, pliability, and durability, by any other material, except perhaps the dried and well-worked pizzle of the bull, which in olden times was largely used for connecting the two parts of the threshing-flail. The eelskin should be tacked to a board, rubbed well with fat of some kind, dried, and then worked over the round edge of a board until it is perfectly supple. It may then be cut into strips of any width. As a lacing for belts, or as a material for making "catgut," it is unequalled. A mill-owner who has used eelskins largely for belt-lacing says: "Eelskins make the best possible strings for lacing belts. One lace will outlast any belt, and will stand wear and hard usage where hooks or any other fastenings fail. Our mill being on the bank of the river, we keep a net set for eels, which, when wanted, are taken out in the morning and skinned, and the skins are stuck on a smooth board. When dry we cut them in two strings, - making the eelskin, in three hours from the time the fish is taken from the water, travel in a belt.
