A., Philadelphia, asks : "Is there any use in a change of seeds from other localities ?"

[There may be "use," or there may be loss. If. we turn a wheel round, it keeps going awhile after the hand is withdrawn. The same law holds good through all nature. A Peach forced for several years in hot-house will bloom a week or two before a Peach of the same kind fresh brought into the heat; and peculiar forms of plants - new species or varieties - continue to exist long after the circumstances which created them have ceased. Hence, seeds or trees may carry with them to a new location certain characters desirable or undesirable, which will last for a time, though perhaps the same species or variety already there may not have, or may have lost them. - Ed. G. M].
