Still, there were some stout hearts in Edinburgh who did their best to keep up the courage of the rest and to keep out the enemy. Andrew Fletcher and Duncan Forbes were of the number. M'Laurin, the mathematician, turned his genius to the bettering of the fortifications. Old Dr. Stevenson, bedridden but heroic, kept guard in his arm-chair for many days at the Netherbow gate. The great question was, would Cope come in time? Cope was at Aberdeen. Cope had put his army upon transports. Cope might be here to-morrow, the day after to-morrow, to-day, who knows? But in the mean time the King's Dragoons, whom Cope had left behind him when he first started out to meet the Pretender, had steadily and persistently retreated before the Highland advance. They had now halted--they can hardly be said to have made a stand--at Corstorphine, some three miles from Edinburgh, and here it was resolved to do something to stay the tide of invasion. Hamilton's Dragoons were at Leith. These were ordered to join the King's Dragoons at Corstorphine and to collect as many Edinburgh volunteers as they could on their way. Inside the walls of Edinburgh it was easy enough to collect volunteers, and quite a little army of them marched out with drums beating and colors flying at the heels of Hamilton's Dragoons. But on the way to the town gates the temper of the volunteers changed, and by the time that the town gates were reached and passed the volunteers had dwindled to so pitiable a handful that they were dismissed, and Hamilton's Dragoons proceeded alone to join Cope's King's Dragoons at Corstorphine.
