The Mulholland locomotive has been so improved that now a full train of passenger cars is regularly run froji Philadelphia to Pottsville, 94 miles, with two tons of Schuylkill coal, working up to fast time, viz., four hours, including 18 stoppages. The superior adaptation of hard coal to road engines is now conclusively established to the satisfaction of this railway company. The Norris factory is now constructing five Mulholland locomotives for the Camden railroad, and the Reading Railroad Co. is adding to this large number now in use as fast as it can get them built ; intending, in two years, to have no others in use. They find them su-1 perior to wood engines in power and steadi- J ness, for heavy freight, at ten miles per hour, and manifold cheaper, of course. And after an experience of nearly two years, they are enabled to assure us that they are entirely free from the unusual burning out of the firebox, formerly thought incurable. Copper boilers also, which were supposed alone capable of resisting the destructive heat of anthracite, are dispensed with, common iron being found to answer fully in the Mulholland locomotive. J. *. #. Philadelphia, 1863.
