NIAGARA. 183

 through the intermittent spray-gusts. We were right 

 under the tower. A little farther on the cataract, after

 knew no more of me than that I enjoyed the wildness 

 of the scene ; but as I bent in the shelter of his large 

 frame he said, * I should like to see you attempting to
