thirty times that Of the river water and making the

Walker that II is only when the quantities redu ed TO

Mr. Leslie who rays that any effect from frcshet nj the

Now II this test OF OF the propor'ionae

Hudson Delaware any other Of tidal rivers OF
magnitude much greater disparity would be found TO
exist tor this county where the annual fall OF rains ID
much below that Of England the volume OF the river
