At a recent meeting of the St. Louis Academy of Science, Dr. Engelmann exhibited a section of the trunk of Juniperus califomica var., which was not quite four inches in diameter and yet showed an unmistakable age of 127 years, each ring being on an average about one-fifth of a line wide. The largest growth in ten years had been about 4 lines, the smallest during a similar period about 1 1/2 line.
