made with cross beams within and without, with planks in contrary
directions. And this ship must have attached to it, a foot below the
water, an iron-shod spike of about the weight and size of an anvil;

Have a coat made of leather, which must be double across the breast,
that is having a hem on each side of about a finger breadth. Thus it
will be double from the waist to the knee; and the leather must be
quite air-tight. When you want to leap into the sea, blow out the
skirt of your coat through the double hems of the breast; and jump
into the sea, and allow yourself to be carried by the waves; when
you see no shore near, give your attention to the sea you are in,
and always keep in your mouth the air-tube which leads down into the
coat; and if now and again you require to take a breath of fresh
air, and the foam prevents you, you may draw a breath of the air
within the coat.
