work, that their prognostications of failure entirely ceased. From that time the principles introduced by Mr. Fairbairn have been adopted wherever steam is employed as a motive power in mills.
Mr. Fairbairn and his partner had a hard uphill battle to fight while these improvements were being introduced; but energy and perseverance, guided by sound judgment, secured their usual reward, and the firm became known as one of the most thriving and enterprising in Manchester. Long years after, when addressing an assembly of working men, Mr. Fairbairn, while urging the necessity of labour and application as the only sure means of self-improvement, said, "I can tell you from experience, that there is no labour so sweet, none so consolatory, as that which is founded upon an honest, straightforward, and honourable ambition." The history of any prosperous business, however, so closely resembles every other, and its details are usually of so monotonous a character, that it is unnecessary for us to pursue this part of the subject; and we will content ourselves with briefly indicating the several further improvements introduced by Mr. Fairbairn in the mechanics of construction in the course of his long and useful career.
His improvements in water-wheels were of great value, especially as regarded the new form of bucket which he introduced with the object of facilitating the escape of the air as the water entered the bucket above, and its readmission as the water emptied itself out below. This arrangement enabled the water to act upon the wheel with the maximum of effect in all states of the river; and it so generally recommended itself, that it very soon became adopted in most water-mills both at home and abroad.[6] His labours were not, however, confined to his own particular calling as a mill engineer, but were shortly directed to other equally important branches of the constructive art. Thus he was among the first to direct his attention to iron ship building as a special branch of business. In 1829, Mr. Houston, of Johnstown, near Paisley, launched a light boat on the Ardrossan Canal for the purpose of ascertaining the speed at which it could be towed by horses with two or three persons on board. To the surprise of Mr. Houston and the other gentlemen present, it was found that the labour the horses had to perform in towing the boat was mach greater at six or seven, than at nine miles an hour. This anomaly was very puzzling to the experimenters, and at the request of the Council of the Forth and Clyde Canal, Mr. Fairbairn, who had already become extensively known as a scientific mechanic, was requested to visit Scotland and institute a series of experiments with light boats to determine the law of traction, and clear up, if possible, the apparent anomalies in Mr. Houston's experiments. This he did accordingly, and the results of his experiments were afterwards published, The trials extended over a series of years, and were conducted at a cost of several thousand pounds. The first experiments were made with vessels of wood, but they eventually led to the construction of iron vessels upon a large scale and on an entirely new principle of construction, with angle iron ribs and wrought-iron sheathing plates. The results proved most valuable, and had the effect of specially directing the attention of naval engineers to the employment of iron in ship building.
