but eventually safe process was conducted by Captain Basil Ball. He ordered a crew of sailors to be brought up from the man-of-war guardship in the Firth of Forth; and by their united efforts the destruction of the ruined walls was at last successfully accomplished.

In the autumn of 1823, when I was fifteen years old, I had a most delightful journey with my father. It was the first occasion on which I had been a considerable distance from home. And yet the journey was only to Stirling. My father had received a commission to paint a view of the castle as seen from the ruins of Cambuskenneth Abbey, situated a few miles from the town. We started from Newhaven by a small steamboat, passing, on our way up the Firth, Queensferry, Culross, and Alloa. We then entered the windings of the river, from which I saw the Ochils, a noble range of bright green mountains. The passage of the steamer through the turns and windings of the Forth was most interesting.

We arrived at Stirling, and at once proceeded to Cambuskenneth Abbey, where there was a noble old Gothic tower. This formed the foreground of my father's careful sketch, with Stirling Castle in the background, and Ben Lomond with many other of the Highland mountains in the distance. As my father wished to make a model of the Gothic tower, he desired me to draw it carefully, and to take the dimensions of all the chief parts as well as to make detailed sketches of its minor architectural features. It was a delightful autumn afternoon, and, before the day had closed, our work at the abbey was done. We returned to Stirling and took a walk round the castle to see the effect of the sun setting behind the Highland mountains.

Next morning we visited the castle. I was much interested with the interior, especially with a beautifully decorated Gothic oratory or private chapel, used by the Scottish kings when they resided at Stirling. The oratory had been converted with great taste into an ante-drawingroom of the governor's house. The exquisite decorations of this chapel[note: This exquisite specimen of a carved oak Gothic apartment had a terrible incident in Scottish history connected with it. It was in this place that The Douglas intruded his presence on James the Third. He urged his demands in a violent and threatening manner, and afterwards laid hands upon the king. The latter, in defending himself with his dagger, wounded the Douglas mortally; and to get rid of the body the king cast it out of the window of the chapel, where it fell down the precipitous rock underneath. The chapel has since been destroyed by fire.]

were the first specimens of Gothic carving in oak that I had ever seen, and they seemed to put our modern carvings to shame. The Great Hall, where the Scottish Parliament used to meet, was also very interesting as connected with the ancient history of the country.

From Stirling we walked to Alloa, passing the picturesque cascades rushing down the cleft's of the Ochils. We put up for the night at Clackmannan, a very decayed and melancholy-looking village, though it possessed a fine specimen of the Scottish castellated tower. It is said that Robert Bruce slept here before the Battle of Bannockburn. But the most interesting thing that I saw during the journey was the Devon Ironworks. I had read and heard about the processes carried on there in smelting iron ore and running it into pig- iron. The origin of the familiar trade term "pig-iron" is derived from the result of the arrangement most suitable for distributing the molten iron as it rushes forth from the opening made at the bottom part of the blast-furnace; when, after its reduction from the ore, it collects in a fluid mass of several tons weight. Previous to "tapping" the furnace a great central channel is made in the sand-covered floor of the forge; this central channel is then subdivided into many lateral branches or canals, into which the molten iron flows, and eventually hardens.

The great steam-engine that worked the blast furnace was the largest I had ever seen. A singular expedient was employed at these works, of using a vast vault hewn in the solid rock of the hillside for the purpose of storing up the blast produced by the engines, and so equalising the pressure; thus turning a mountain side into a reservoir for the use of a blast-furnace. This seemed to me a daring and wonderful engineering feat.
