[w-] Walter White is in the [3] basement of the [-(e)i] beach house by the bay where he is trying to determine his 纬 latitude. The meth he wants to cook there in the basement can only be done at certain 纬 latitudes. He gets a 韦 tanned hide and wraps it with 纟 silk and pours sand over it. By looking at how the sand bounces off the 纟 silken 韦 tanned hide, he can determine the 纬 latitude. The 纬 latitude is appropriate, so now he can prepare to make meth down in the sandy basement.
