The St. Lawrence here falls eighty-seven feet in the distance of seven miles. Steamboats and other vessels go down the rapids, but are obliged to ascend through the Beauharnois Canal, which we entered at about noon. This canal is fifteen miles long, fifty feet wide, and nine feet deep. The navigation of the rapids is very dangerous, and vessels are sometimes wrecked upon the submerged rocks. A sloop, loaded with staves and lumber, was lying in the midst of the foaming rapids, where it had struck the day before while guided by an unskillful pilot. The canal voyage was slow, for we passed nine locks before we reached the waters above Lake St. Louis, an expansion of the river, where the Ottawa or Utawas comes sweeping around each side of Isle Pero, at its mouth, and swells the volume of

* These rapids are so called from the circumstance that a village of the same name is near. This was considered by the Canadian voyageurs the place of departure when going from Montreal on fur-trading excursions, as here was the last church upon the island. This fact suggested to Moore the thoughts expressed in the first verse of his Canadian Boat Song :

"Faintly as tolls the evening chime,

Our voices keep tune and our oars keep time,

Soon as the woods on shore look dim,

We'll sing at St. Ann's our evening hymn.

Row, brothers, row, the stream runs fast,

The rapids are near, and the daylight's past."

* Moore says, in reference to this song, "I wrote these words to an air which our boatmen sung to us frequently while descending the St. Lawrence from Kingston to Montreal. Our voyageurs had good voices, and sung perfectly in tune together. I remember when we had entered, at sunset, upon one of those beautiful lakes into which the St. Lawrence so grandly and unexpectedly opens, I have heard this simple air with a pleasure which the finest compositions of the first masters have never given me."
