Kamehameha V's time capsule

I saw an article on CNN.com about the (extremely quick) discovery of a time capsule under the cornerstone of Aliiolani Hale in Honolulu. It's too bad that they can't dig it up. It would be neat to see what was in there--possibly even books that have been lost in the century since the capsule was buried.

It still annoys me sometimes that the Ancient Hawaiians never developed writing.
