Now the Isle of Ailsa is little more than a great lumping crag set askew in the sea. Nevertheless, it has both landing place and pasturage, house of refuge and place of defence. The island was not new to me, for I had once upon a time gone thither out of curiosity after the matter of Barclay, Laird of Ladyland—who, in his madness, thought to make it a place of arms for the Papists in the year of the Spanish Armada, but was prevented and slain at the instance of Andrew Knox, one of the good reforming name, minister of Paisley. This last was a wonderfully clever man and accounted a moving preacher; but on this occasion he showed himself a better fighter—which upon Craig Ailsa, at least, is more to the purpose.
It was the dusk of the morning when we ran into the spit of shingle which is upon the eastern side and, watching our chance, we drew the boat ashore. The sea was chill and calm, only a little ruffled by the night wind, and the sun was already brightening the sky to the east, so that the Byne Hill and Brown Carrick stood black against it.
With great stealth and quiet we climbed up the narrow path, seeing nothing, however, save a pasturing goat that sprang away as we came near. It was eerie enough work, for the seabirds clanged around us, yammering and chunnering querulously among themselves on the main cliffs at the farther side of the isle. It grew a little lighter when we came out upon the narrow path which leads to the castle.
Suddenly the dark door of the tower loomed before us, very black and grim. I declare it was like marching up to the cannon's mouth to walk up that little flight of stairs which led to the door in the wall. Nevertheless, I clambered first, with a curious pricking down my back and a slackness about the knees. So all unscathed we entered. There was only emptiness in all the chambers. The castle had been almost wholly ruined and spoiled, for since its taking by the Protestant party, it had not been touched nor put in defence. 'Now I will bring up the provender. Keep you the castle,' said I to the little Dominie, as soon as we were certified that we were first in possession.
So I went down and made first one backload and then another of those things which we had bought at Girvan and placed in the boat. I brought up also all the ammunition for the hackbutt and the pistols. Before I had finished the sky grew grey and clear, the day breaking nobly with only a rack of cloud racing up the far side of Kilbrannan Sound to hang upon the chill shark's teeth of the mountains of Arran. Upon my return I was glad to find the castle intact, and the little man seated calmly with a book in his hand.
'Did you never so much as shut the outer door?' I asked him.
'And shut you without,' said he. 'Is it likely? Ye might have had to come along that footpad with only your limber legs to keep your tail, and Tam o' Drummurchie or Sawny Bean jumping ahint ye!'
So before we went to examine the nooks and crannies of the Craig either for enemies or treasure boxes, we resolved to put the castle into as good a state of defence as we could.
First we drew in the rough wooden steps which led to the door in the wall by which we had entered, so that only the little projections whereon the wood had rested were left to afford foothold to any besieger. Then we closed and barricaded the door, for the huge iron bolt was yet in its place and ran securely into the stone of the wall itself for quite two feet.
When the day broke fully, I went up to the turret top to look about me.
