This is due to the increase in- the passing freighttonnage, there being more vessels in the freight-carrying trade year by year passingthrough these locks. This will continue to increase until the present locks will beworked to their full capacity, at which time the average interval between successivelockages will have reached a minimum for each lock. Up to the present timethe greatest number of lockages for each lock in a day, and the consequent intervalsare as follows:— Lock, Number of lockages. Interval, Canadian 34 42 mmutes, Poe 36 40 Weitzel 41 35 Single lockages have been made in time tlian the above intervals show; asfor instance, a single steamer has been locked through th
