- I So all through the State, on the highest ridges of the glacial drift.forma- tion, myriads of young oaks and hickories are springing up thickly, now that the fires have been suppressed. No man has sown the seeds for their production. Whence come they, if not from the germs implanted by the provident squirrel and other rodents in the time long past ? These germs have shown their vitality and their great power of endurance (perhaps for centuries) for many generations, and their ability, when f...avoring circum- stances occur, to spring up and occupy the land. No more interesting circumstance connected with the future f orestal pros- pects of your State could be presented to the student of sylvaculture. If you insist on planting the box-elder at all, let it be the belt or the rows, in which to plant the nuts and acorns, as its premature destruction for fuel will not be regretted. In building up a grove of Black walnut, a similar plan may be adopted, with this modification: Plant the nuts at the same time as the "cheap trees," and let them occupy the middle row of the three rows, before planted with box-elder or Cottonwood.
