Steam is furnished by three scotch boilers to a triple expansion en- gine driving a single propeller, giving the vessel a speed of 12 miles per hour.

No radical departures have been made from usual practice, but it can be said that the vessel in design and construction is particularly suited for her trade and that she has given excellent service. She is so built that there isn’t much that could go wrong. She has the regular triple expansion reciprocating steam engine, driving a _ single propeller. Steam is supplied by three scotch boilers burning hand fired coal. The hull scantlings and engineering details of the vessel though not classed have been kept equal to American Bureau rules.
