Not less characteristic of the man were the free and friendly relations into which he entered with some of the common people who were thrown in his way. Usually he travelled on the stage-coach, but occasionally he hired a carriage, and not unfrequently a gig, with the driver at his side. He had the feeling that he would enjoy his holiday all the more if it were mingled with a little study. Accordingly we find that, when passing slowly in his gig over some monotonous part of the road, he would pull from his pocket a grave book, like Mede's Latin Lectures on Prophecy, and have a spell of theological reading. But his eye seemed always to be open to any object of interest, whether in the scenery or in the places he passed. With his driver he entered into friendly relations, although he sometimes found him a very dolt. At Huddersfield he hired a gig to carry him through some of the remarkable scenes of Derbyshire. The driver was a grave, silent, and simple lad of twenty-two, and he made a practice of taking him with him to the caverns and other places of interest that he visited. At the Peak Cavern he had to change his coat and hat, 'and a worse coat or a worse hat I never saw on the back or head of any carter or scavenger in the land, insomuch that I was a spectacle to the children of the village, who shouted and laughed behind me, and even the driver of the gig could not restrain his merriment. I always take him to the sights along with me; first, because I found a great ignorance of Derbyshire curiosities in Huddersfield, and I want to make him more enlightened and enlarged than his fellow-citizens; secondly, because I always feel a strong reflex or secondary enjoyment in the gratification of other people, so that the sympathy of his enjoyment greatly enhances my own; and thirdly, because I get amusement from the remarks of his simple wonderment and not very sagacious observations; and it has now passed into a standing joke with me, when leaving any of our exhibitions, that "there is no such fine sight to be seen at Huddersfield."' At Chatsworth, the Doctor gave the lad his hat and silver-headed cane to carry; he followed at a respectful distance, while his master went before with a book in his hand, taking notes of whatever was memorable. He found afterwards that his picturesque appearance and unusual employment had excited much speculation among other visitors as to who he was, and that the conclusion to which they all came was that he was a foreign nobleman. At Matlock he parted with his driver, who, he found, could hardly read; he warned him that many perish of lack of knowledge, and that he must learn to study his Bible, which was able to make him wise unto salvation through faith in Jesus Christ.
Chalmers did not always show the same patience and consideration for his fellow-travellers. Once, in Yorkshire, waiting at the door of the coach-office, he found himself beside a herd of swine, whose motions and operations he studied with interest; on the top of the coach he found a company much of the same order--'fat and unintelligent, with only pursy and vesicular projections on each side of their chins, and a superabundance of lard in their gills, whose manners well-nigh overset me, overloading our coach with their enormous carcasses, and squeezing themselves, as they ascended from various parts of the road, between passengers already in a state of compression, to the gross infraction of all law and justice, and the imminent danger of our necks.' It was enough, he said, to make any man a Tory. Naturally, Chalmers had much of the passion which bursts out in this bit of sarcasm; but, before the end of his letter, he feels that he has gone too far, his better nature asserts itself, and he gives utterance to a milder spirit. 'I feel it wrong to nourish contempt for any human being: "Honour all men," is the precept of Scripture. We should not despise any of those for whom Christ died; and the tendency to do so is one of those temptations to which refinement and knowledge are apt to expose us, and which ought to be resisted.' The 'old Adam' was not extinct; but at the bottom of his heart Chalmers wished him destroyed.
