Generally these countings weremade for purposes other than the mere determination [of age,\^butnevertheless serve to-day as incontrovertible, accurate, ^evidence atleast for Europe and its species. But there are also in the same. Fig. 7.

In addition, we have inour own country many hundred countings on record and thousandsmore not permanently recorded, proving the same for the forestspecies of the temperate zone in the United States. Should any one doubt, let him but test the matter on a young tree, as the Red Pine or White Pine, where the part grown during the
