sapwood

The sapwood of the Western Red Cedar (Thuja plicata) is thin with a light yellow tinge.

西部红杉(侧柏木)是较薄，有黄色。

Or you can use a drawknife to strip the bark and sapwood from each stave (what the bugs love), and seal the back with several coats of shellac.

或你能使用一个刮刀脱衣来自每个做木桶的木板(什么疯狂的爱)的吠声和,而且用虫漆的一些外套封闭背面。
