We are glad to pereceive the activity that prevails on the Welland Canal. Several vessels have already arrived - understanding that the canal was in excellent repair. This they found, on their arrival, to be correct, as they met with no obstacle in the prosecution of their voyage. Perhaps there is not an instance on record when the navigation was open at an earlier period, and it is certainly very gratifying to see schooners arriving in the middle of April, laden with wheat, from below - a circumstance of itself sufficient to show that business is already progressing - not withstanding the difficulties thrown in the way, by the operations of the banks, which we trust will henceforth conduct their affairs in a more liberal scale.
The sch. Shamrock passed through here last Thursday, heavily laden, for Toronto. The Victory, laden with salt and flour, passed on the 18th inst., for Amherstburgh. The Hamilton arrive don the 15ht from Port Hope, and cleared on the 18th, for Prescott. Two fine American schooners, the Charles Crocker and the Albany, from Oswego, bound for Cleveland, passed this place on Friday. We hope this early spirit of enterprise will be followed up, as we can assure our American friends, that they will find no impediment in their passage through this channel, either from any defect in the state of the works, or other dention, from the officiers in charge; as it is the desire of the Lieut. Governour, publickly announced, that every facility shall be afforded to the American Merchants. S.C.
