whofe breadth is not very confiderable, and 

 falls over the fleep fide of a hill, confifting 

 entirely of black lime-flate. The fall is 

 now at the bottom of a little creek of the 

 river. Both fides of the creek confift mere- 

 ly of black lime-flate, which is very much 

 cracked and tumbled down. The hill of 

 lime-flate under the water-fall is quite per- 

 pendicular, and one cannot look at it with- 

 out aflonifliment. The rain of the prece- 

 ding days had encreafed the water in the 

 river, which gave the fall a grander appear- 

 ance. The breadth of the fall is not above 

 ten or twelve yards. Its perpendicular height 

 Mr. Gault flier and I guefled to be between 

 a hundred and ten and a hundred and twen- 

 ty feet ', and on our return to ^ebec, wc 

 found our gueis confirmed by fevcral gen- 

 tlemen, who had adtually meafured the fall, 

 and found it to be nearly as we had conjec- 

 tured. The people who live in the neigh- 

 bourhood exaggerate in their accounts of it, 

 ablblutely declaring that it is three hundred 

 feet high. Father Charlevoix -^ is too fparing 

 in giving it only forty feet in height. At 

 the bottom of the fall, there is always a 

 thick fog of vapours, fpreading about the 

 water, being refolved into them by its vio-
