On her first trip down she left Buffalo Sept. 12th, and arrived at West Troy, the 19th, in 7 days 4 hours, total time, and reached New York the 21st, in 8 days 13 hours, total time, with 200 tons of freight. In some way she reduces her 7 days 4 hours to 4 days 8 hours, net time, to Troy; and her 8 days 13 hours, to New York, to 5 days 17 hours. Second trip down was from Buffalo to Waterford, when she was longer upon the canal than on her first trip of over 7 days. Third trip down, left Buffalo Nov. 9th, and arrived at Troy 15th, and New York 17th, or over 6 days to Troy, and 8-1/4 to New York, with 5/6 horse cargo. This canal trip was during the horse epidemic, and the large number of boats laid up made it very favorable for steam. But the _Baxter's times_ have been developed by a model which would require _one-third of a common boat to be rebuilt_--one-sixth at the bow and one-sixth at the stern--it is, therefore, proper to state, that if we put her machinery and steam capabilities into a common boat--and the seven thousand such boats cannot be dispensed with--it would be _very slow_, as her speed would be reduced by three causes: 1st. Because of an increased velocity of bow displacement at a reduced speed of boat. 2d. Because of an increased velocity of stern replacement, at a reduced speed of boat, against the mechanical or counteracting propelling currents. 3d. Because the percentage of wasted power is increased, and of utilized is diminished, by greater resistance to motion. The _Wm. Newman_ left New York Oct. 30th, and arrived at Buffalo Nov. 7, in 8 days, with 120 tons of freight. RELATIONS OF TIME--TWELVE YEARS AGO AND NOW. The _Wack's_ through time from Buffalo to West Troy, with boat in tow, is the same as the _Baxter's_ average without tow. The _Ruggles'_ net time, from Buffalo to New York, with boat in tow, is only 21 hours in excess of the _Baxter's_ shortest net time without tow. The through times of the _Eclipse_ and _Gold Hunter_, from Buffalo to West Troy, without tow, are just equal to the _Baxter's_ first and second trips. The _Rotary's_ through time up, with half freight, is nearly one day less than the _Byron's_, _Baxter's_ or _Newman's_ shortest through time. Her net time is 17 hours less than the _Baxter's_ shortest net time. The net time of the tugs, each with three boats in tow, is nearly equal to the _Baxter's_ without tow, from Buffalo to West Troy.
