Among the eminent strangers who visited Scotland about this time none excited a livelier interest in Dr. Chalmers's mind than Dr. Merle D'Aubigne, who came in 1845, when in the full flush of his fame as the popular historian of the Reformation.
At the Disruption there was a vast amount of work to be done, for it would have required more than seven hundred churches to accommodate all the congregations that adhered to the Free Church. There were, besides, many cases of peculiar difficulty, caused chiefly by the refusal of proprietors to grant sites for churches and manses on their properties, a refusal which on vast estates like those of the Duke of Sutherland or the Duke of Buccleuch would have amounted to an absolute extinction of the church. Dr. Chalmers, however, under the influence of his strong desire for a sabbatic decennium, kept clear of the ordinary work of the church, excepting the Sustentation Fund and his college lectures. As for the college itself, it was mainly in the hands of Dr. Welsh, until his lamented death in 1845, when Dr. Chalmers felt constrained to become convener of the College Committee. Among other services, Dr. Welsh took in hand to provide for a college building, which it was proposed to erect from the contributions of twenty subscribers of L1000 each. This was a serious undertaking at a time when the wealthier friends of the church had been straining all their energies for the Building, Sustentation, and Mission Funds. But the whole sum was speedily contributed in the way proposed, and though in the end the price of the site and the cost of the building amounted to more than double the sum named at the beginning, the whole was ultimately provided. Such liberality for college purposes was due in a great degree to the profound regard in which Dr. Chalmers was held, and in a somewhat less degree to his colleague Dr. Welsh.
It must be owned that Dr. Chalmers was not satisfied with the success of the Sustentation Fund. It had been adopted not only unanimously but enthusiastically by the whole church, and considering all that had to be done for other purposes, it was marvellous that in the first year it amounted to L68,700, enough to furnish fully L100 to six hundred ministers. That, however, was but two-thirds of the amount which Chalmers had named as the minimum payment to each minister from this fund. And, besides, there were many additional ministers to be provided for, needed by the new adhering congregations; and moreover,--and this was never absent from his thoughts--there was to be considered the vast home-mission work needed in order to realise his lifelong desire to overtake the whole spiritual destitution of the country. It was the inadequacy of the Sustentation Fund to realise this further object that was the chief cause of his disappointment. Moreover, he found in the machinery of his scheme a serious leak, which bade fair to ruin it. Every congregation was to receive an equal dividend for its minister from this fund, whatever might be the amount of its own contributions. In order that this provision might work satisfactorily, it was necessary that congregations should make an equal effort for the fund. But it was soon found that many congregations were steeped in selfishness, and, while drawing their equal dividend, their contributions were but a fraction of what they should have been. Chalmers had calculated on a brotherly spirit and a brotherly conscience, which he now found were often wanting. He became alarmed for the future, and proposed a modification of the original arrangement, to the effect that no congregation should receive from the fund more than its own contribution and a half more. But it was too late. The fund had been constituted on the footing of an equal dividend, and there was a strong opposition to the change. Chalmers remonstrated by word of mouth and by pamphlets on the 'Economics of the Free Church.' All that the Assembly would allow was that the new plan should be tried with new congregations. But as the new congregations were generally comparatively poor, the result was something like starvation to their ministers; and, after a short trial, the plan was given up. But no one could deny the serious nature of the evil that Chalmers had pointed out, and for many a long year there were perplexed discussions as to the remedy. Even now, though the leak has been abundantly dealt with, it has not been quite overcome. In his remonstrances, Chalmers showed more vehemence than was perhaps reasonable, considering that it was the defect of his own original scheme that caused the difficulty. But his vehemence was due to the conviction that came home so strongly to him, that the Sustentation Fund could not become the instrument of carrying out his dearly-cherished project,--of recovering the whole waste-places of Scotland, and making them parts of the vineyard of the Lord. The thought saddened him, and it led him to speak more disparagingly of what the Free Church had accomplished, and what the Sustentation Fund had accomplished, than was altogether deserved.
