Dr. Mair packed up his quack medicine in silence, which was meant to be impressive. He sighed, as if in sorrow for human ignorance and unbelief; but seeing no favourable effect produced on the Sergeant he said: "Your blood be on your own unbelieving head! I am free of it." "Amen!" said the Sergeant; "and gang about yer business to auld wives and idewits, that deserve to dee if they trust the like o’ you." And so the great Dr. Mair departed in wrath--real or pretended--to pursue his calling as a leech, verily sucking the blood of the credulous, of whom there are not a few among rich and poor, who, loving quackery, are quacked.[#] [#] It may be added as an instructive fact, that such leeches suck at least £300,000 a year out of the people of this country. Having disposed of the Quack, we now back into the main line, and resume our journey. CHAPTER XXII CORPORAL DICK Corporal Dick, who lived in the village of Darnic, several hours’ journey by the "Highflyer" coach from Drumsylie, came at this time to pay his annual visit to the Sergeant. The Corporal, while serving in the same regiment with Adam, had been impressed, as we have already indicated, by the Christian character of his comrade. Those early impressions had been deepened shortly after his return home from service. We need not here record the circumstances in which this decided change in his sentiments and character had taken place. Many of our Scotch readers, at least, have heard of the movement in the beginning of this century by the devoted Haldanes, who, as gentlemen of fortune, and possessing the sincerest and strongest Christian convictions, broke the formality which was freezing Christian life in many a district of Scotland. They did the same kind of work for the Church in the North which Wesley and Whitfield had done for that in the South, though with less permanent results as far as this world is concerned. Dick joined the "Haldanites". Along with all the zeal and strictness characteristic of a small body, he possessed a large share of _bonhomie_, and of the freedom, subdued and regulated, of the old soldier.
