Letter from E. L. Kammerer to John D. Siebenthaler thanking him for his compliments on the Ginkgo issue of the Bulletin of Popular Information. Mr. Kammerer also writes that they immediately investigated the warm bark theory that Mr. Siebenthaler had mentioned, but their results were inconclusive and he says they will continue to investigate.
