Leaks, stopping:
You can sometimes stop or check a leak by calking from the inside, if you can get at it; but great care should be exercised in driving the cotton not to push it in too hard, as you may drive out what calking is in the seam, and make the leak worse. Holes, if they can be got at from the outside, can be covered with sheet lead, copper, or a piece of rubber boot leg. In an emergency the same can be used inside to check the flow. Barge men frequently use horse manure to stop leaks in the seams when near the water line; they throw it overboard and let the water draw it into the crevice. I have checked a leak by running a boat on a bar of soft sand, thus getting sand in the seam.
