How to heart a wall?
Gaps in the interior of the wall, between the face stones, should be tightly filled with small stones. The tighter the hearting , the stronger the wall. However fewer larger hearting stones are much stronger than many small little bits. Anything that can be easily shoveled is too small to use for hearting (and absolutely no concrete gravel or soil!). Hearting stones are much better if they are flat or angular. Rounded stones can act like ball bearings. Hearting stones should be placed individually, not randomly thrown in. Hearting takes place as the wall is being built, make sure each course is completely hearted before beginning the next course. Not properly hearting a wall allows stones to move independently of one another, resulting in a structurally weak wall that will not last.
How should a wall be built?
Walls should be built so that the stones and courses are level. This is more apparent when using flat stones but applies to nearly all walls.

Many walls are built with quite irregular shaped stone, when this is the case focus on keeping the top of the stones level. That makes it easier to build on top of. When this is not possible to have a level top, slope it top toward a neighboring stone to the right or left. Not into the core of the wall or pitched out.
