Delivery to the owner was made after a maiden voyage from the builder’s plant via the Ohio and Mississippi rivers, Gulf of Mexico and Atlantic coast, a total distance of about 4000 miles, which in itself is rather an unusual performance. From Pittsburgh she carried a cargo of food products for delivery to river ports on the way. The trip from Fittsburgh to New Orleans, a distance of 2000 miles, is reported to have been made in less than seven days and the remainder of the voyage from New Orleans to Baltimore, about 2000 miles, in six days. The Rep Srar is now in service with other vessels of the owner’s fleet on Chesapeake bay in fast freight delivery to interior points around Baltimore by means of a coordinated trucking service. This is a happy illustration of a combination of efficient means of transportation for satisfactory service.
