As papa and Uncle Tom did not wish to take the yachts further, we got on board one of the steamers running up to Glasgow.  During the passage we passed numbers of steamers, large and small, rushing up and down the stream at a rapid rate; and sailing vessels of all sizes outward-bound, or returning home; the former laden with the cotton and woollen manufactures produced in Glasgow and the neighbourhood, giving us some idea of the vast amount of trade carried on in the city. Curious-looking steam dredges were also at work, with wheels ever revolving, ladling up the mud from the bottom of the river--an endless task, for fresh mud is constantly being washed down from the upper parts of the stream.  Clouds of smoke and increasing signs of activity showed us that we were approaching Glasgow.
