__Nkw Bo*t.—The Pvntify infettf ftoQFV of t Iio Olive Jirattc/i, and youngest .sister of the “ O/iw ZW,” though far more comely in its proportions, has recently been added to the already numerous family of river steamers. She visited our port on Saturday last. Though of somewhat diminutive size, she presents an appearance at once neat and atr tractive. Her speed, wo should judge, is about equal to that of other river steamers. We understand slie is intended for a night boat, leaving this port and Grand Rapids every alternate evening. She is under the superin tendeiico of (’apt, Gaxoe.
