We left Winchester by evening train to the Dolphin, Southampton, and slept there. At nine in the morning we went by steamboat down the river to Ryde in the Isle of Wight: our steamer was going on to Portsmouth, but we thought it better to land at Ryde and take a boat for ourselves. We then sailed out (rather a blowing day) to the vessel attending Col. Pasley's operations, and after a good deal of going from one boat to another (the sea being so rough that our boat could not be got up to the ships) and a good deal of waiting, we got on board the barge or lump in which Col. Pasley was. Here we had the satisfaction of seeing the barrel of gunpowder lowered (there was more than a ton of gunpowder), and seeing the divers go down to fix it, dressed in their diving helmets and supplied with air from the great air-pump above. When all was ready and the divers had ascended again, the barge in which we were was warped away, and by a galvanic battery in another barge (which we had seen carried there, and whose connection with the barrel we had seen), upon signal given by sound of trumpet, the gunpowder was fired. The effect was most wonderful. The firing followed the signal instantaneously. We were at between 100 and 200 yards from the place (as I judge), and the effects were as follows. As soon as the signal was given, there was a report, louder than a musket but not so loud as a small cannon, and a severe shock was felt at our feet, just as if our barge had struck on a rock. Almost immediately, a very slight swell was perceived over the place of the explosion, and the water looked rather foamy: then in about a second it began to rise, and there was the most enormous outbreak of spray that you can conceive. It rose in one column of 60 or 70 feet high, and broad at the base, resembling a stumpy sheaf with jagged masses of spray spreading out at the sides, and seemed to grow outwards till I almost feared that it was coming to us. It sunk, I suppose, in separate parts, for it did not make any grand squash down, and then there were seen logs of wood rising, and a dense mass of black mud, which spread gradually round till it occupied a very large space. Fish were stunned by it: our boatmen picked up some. It was said by all present that this was the best explosion which had been seen: it was truly wonderful. Then we sailed to Portsmouth.......The explosion was a thing worth going many miles to see. There were many yachts and sailing boats out to see it (I counted 26 before they were at the fullest), so that the scene was very gay. * * * * * Here are some notes on York Cathedral after the fire: RED LION HOTEL, REDCAR, _1840, Sept. 7_.
