Kron says of Tan Oak bark: Do not keep my bark over two years, usually not more than one. The leakage from rain, the damp and fog moisture causes more or less loss. If it were perfectly shedded in a dry place it could be kept longer. There is an optimum period when it is best to use it, that is when it will leech most perfectly. It will not leech well at all when it is green or half-dry, there is much loss. It will leech best just when it first becomes perfectly dry-say in January after its peeling. The peeling season lasts until August 1. The hot weather at this

time makes good peeling, but a continuation of hot weather will shorten the peeling period, just as cold nights will shorten it.

Pilkington says: Fire will bind the bark so it will not peel that season. Takes several seasons (Kron says 3) for it to be again peelable. Even then it may peel on one side and not on the other. If the peeling season is shortened by hot weather these trees will be first to bind down.
There is in Watsonville 3 planted trees 30 years old: Redwood 65 ft. h., Big Tree 40 ft. h., Reg Gum 150 ft. h. (ask P. for address of owner).
