During his five years’ incumbency in St. Andrews, he issued two volumes from the press. The first was the third and concluding volume of _The Christian and Civic Economy of Large Towns_. Among the topics embraced in this volume were the Poor-Laws and the Combination-Laws. The particular aspect of the Poor-Laws with which he dealt, and which he most thoroughly condemned, was the application of the poor-rates, as in England, to supplement the wages of ill-paid labourers. Though kindly meant, this arrangement, he held, was an invasion of the relation between master and men so ruinous, and involved a bounty to the masters so unjust, that no toleration ought to be found for it. This was also the general opinion; and the practice was discontinued by law. According to Dr. Chalmers’s biographer, his exposure of the practice formed a powerful contribution towards its removal. In regard to the Combination-Laws, which imposed severe and stringent penalties on any united movements of workmen for increasing their wages, a bill for repealing them had been introduced and carried by Mr. Huskisson, whose efforts to free industry from the fetters of Protection were hailed by Dr. Chalmers with great delight. Unfortunately, the carrying of this measure into law was accompanied by certain deplorable excesses on the part of some classes of workmen, who did not understand how to use their new-found liberty. Dr. Chalmers strongly upheld the righteousness of the repeal of the old laws, mainly on the ground that we ought not to manufacture crime out of acts (such as workmen’s combinations) which the natural conscience does not condemn. But with equal firmness he denounced any interference with the freedom of labour, especially when men on strike coerced and persecuted those that might be willing to work. The experience of seventy years has not materially changed the position. ’Strike, if you please,’ is the voice of reason and justice to workmen; ’but leave those who do not concur with you at perfect freedom to do as _they_ please.’
