Dovetails usually are very strong, even without the use of glue. Many old-fashioned tables and chairs (furniture) use dovetails because it's cheaper than a lot of glue, unless a lot of weight is put on it (and glue tends to break down over time). Wood also expands if there's moisture in the air, so the dovetail joint can (theoretically) tighten.

Dove"tail` (?), n. Carp.
