Yesterday was a fine day, and seldom has our harbor presented a more lively and animated aspect. There being 200,000 bushels of grain afloat, all the elevating power in the harbor was put into requisition. That great establishment, Carrington's "Ontario Grain Warehouse," was elevating at three sides, and discharging into canal boats at the same time. Randall & Co. 's Warehouse, the only one left on the East side, was elevating at the rate of 3,000 bushels per hour, and discharging at the rate of 2,500 bushels per hour. And then the harbor was all alive with the floating grain elevators, transferring the grain from vessels into canal boats.
