BURIED 30 YEARS IN A TREE
Telegraph Bracket Completely Inclosed
in Wood is Found in California
Thirty-six years ago a telegraph bracket and insulator was nailed to a Douglas fir tree near Arcata, Cal. A few years later a falling branch badly damaged it and the wire which it had been supporting was removed. The tree was growing thriftily, adding every summer to its diameter a new layer of woody material, and this growth gradually pushed out around the bracket on all sides, leaving it buried in the tree trunk.
At the end of 26 years the tip of the glass insulator finally disappeared from sight and the only trace of it that could still be seen was a scarcely noticeable lump which looked like nothing more than a healed-over branch stub. A few weeks ago the tree was felled and the wood manufactured into barrel staves. The screech of the saw which happened to graze the edge of the glass called attention to this unusual "fossil."
On splitting open the stave bolt the whole story became clear in all its details. The clearly defined annual rings of the rapidly growing trees from an unimpeachable historical record.
The wood of the insulator bracket is still in good condition and the oak of which it was made had received an unintentional preservative treatment, being thoroughly impregnated with the resin of the surrounding fir. The interesting specimen can now be seen in the wood collection of the forestry division of the University of California.
