I made it on the bevel.
- There is more surface for the nails to grip.
 - There is twice the gripping-surface to each seam.
 - The water will have to seep into it on a slant. Water moves easiest up and down and straight across.
 - In a house people are upright two-thirds of the time. So the seams and joints are made up-and-down. Because the stress is up-and-down.
 - In a bed where people lie down all the time, the joints and seams are made sideways, because the stress is sideways.
 - Except.
 - A body is not square like a cross-tie.
 - Animal magnetism.
 - The animal magnetism of a dead body makes the stress come slanting, so the seams and joints of a coffin are made on a bevel.
 - You can see by an old grave that the earth sinks down on the bevel.
 - While in a natural hole it sinks by the center, the stress being up-and-down.
 - So I made it on the bevel.
 - It makes a neater job.
