The entrance to the Niagara river is very interesting. You pass between the two strong stone forts, raised for the protection of their respective countries; and a hostile vessel would stand but a small chance of keeping clear from danger in passing either Cerberus. It is devoutly to be hoped that all such difficulties will be avoided, by the opposite shores remaining firm friends and allies. The town of Niagara is a quaint, old-fashioned looking place, and belongs more to the past than the present of Canada; for it has not made much progress since it ceased to be the capital of the Upper Province, in spite of its very advantageous and beautiful locality. As you approach Queenstone, the river is much contracted in its dimensions, and its banks assume a bold and lofty appearance, till they frown down upon the waters in stern and solemn grandeur, and impart a wild, romantic character to the scene, not often found in the Upper Province. I never beheld any water that resembled the deep green of the Niagara. This may be owing, perhaps, to the immense depth of the river, the colour of the rocks over which it flows, or it may be reflected from the beautiful trees and shrubs that clothe its precipitous banks; but it must strike every person who first gazes upon it as very remarkable; You cannot look down into it, for it is not pellucid but opaque in its appearance, and runs with a smooth surface more resembling oil than water. The waters of the St. Lawrence are a pale sea-green, and so transparently clear that you see through them to a great depth. At sunrise and sunset they take all the hues of the opal. The Ottawa is a deep blue. The Otonabee looks black, from the dark limestone bed over which it foams and rushes. Our own Moira is of a silvery or leaden hue, but the waters of the Niagara are a bright deep green; and did any painter venture to transfer their singular colour to his canvas, it would be considered extravagant and impossible.
