In our country it is pretty clear varieties of strawberries do not last long. We have to continually replace old with new varieties. We have contended that there is no reason in nature why a variety should not endure for an indefinite period. No degeneracy is due to unfavorable conditions which induces a relaxation of vigor, and the degeneracy is propagated with the variety. In England, where the climate is peculiarly favorable to the health of the strawberry plant, old varieties continue in popularity. Keen's seedling and others, near a half century old, are still the popular favorites to-day.
