The Gas Company was on the point of dissolution when Mr. Samuel Clegg came to their aid. Clegg had been a pupil of Murdock's, at Soho. He knew all the arrangements which Murdock had invented. He had assisted in fitting up the gas machinery at the mills of Phillips & Lee, Manchester, as well as at Lodge's Mill, Sowerby Bridge, near Halifax. He was afterwards employed to fix the apparatus at the Catholic College of Stoneyhurst, in Lancashire, at the manufactory of Mr. Harris at Coventry, and at other places. In 1813 the London and Westminster Gas Company secured the services of Mr. Clegg, and from that time forwards their career was one of prosperity. In 1814 Westminster Bridge was first lighted with gas, and shortly after the streets of St. Margaret's, Westminster. Crowds of people followed the lamplighter on his rounds to watch the sudden effect of his flame applied to the invisible stream of gas which issued from the burner. The lamplighters became so disgusted with the new light that they struck work, and Clegg himself had for a time to act as lamplighter. The advantages of the new light, however, soon became generally recognised, and gas companies were established in most of the large towns. Glasgow was lit up by gas in 1817, and Liverpool and Dublin in the following year. Had Murdock in the first instance taken out a patent for his invention, it could not fail to have proved exceedingly remunerative to him; but he derived no advantage from the extended use of the new system of lighting except the honour of having invented it.[11] He left the benefits of his invention to the public, and returned to his labours at Soho, which more than ever completely engrossed him. Murdock now became completely identified with the firm of Boulton & Watt. He assigned to them his patent for the slide-valve, the rotary engine, and other inventions "for a good and valuable consideration." Indeed his able management was almost indispensable to the continued success of the Soho foundry. Mr. Nasmyth, when visiting the works about thirty years after Murdock had taken their complete management in hand, recalled to mind the valuable services of that truly admirable yet modest mechanic. He observed the admirable system, which he had invented, of transmitting power from one central engine to other small vacuum engines attached to the several machines which they were employed to work. "This vacuum method," he says, "of transmitting power dates from the time of Papin; but it remained a dead contrivance for about a century until it received the masterly touch of Murdock."
