"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." "The sight which I obtained" (Mr.Nasmyth proceeds) "of the vast series of workshops of that celebrated establishment, fitted with evidences of the presence and results of such master minds in design and execution, and the special machine tools which I believe were chiefly to be ascribed to the admirable inventive power and common-sense genius of William Murdock, made me feel that I was indeed on classic ground in regard to everything connected with the construction of steam-engine machinery.

The interest was in no small degree enhanced by coming every now and then upon some machine that had every historical claim to be regarded as the prototype of many of our modern machine tools.

All these had William Murdock's genius stamped upon them, by reason of their common-sense arrangements, which showed that he was one of those original thinkers who had the courage to break away from the trammels of traditional methods, and take short cuts to accomplish his objects by direct and simple means." We have another recollection of William Murdock, from one who knew him when a boy.

This is the venerable Charles Manby, F.R.S., still honorary secretary of the Institute of Civil Engineers.

He says (writing to us in September 1883), "I see from the public prints that you have been presiding at a meeting intended to do honour to the memory of William Murdock--a most worthy man and an old friend of mine.
When he found me working the first slide valve ever introduced into an engine-building establishment at Horsley, he patted me on the head, and said to my father, 'Neighbour Manby, this is not the way to bring up a good workman--merely turning a handle, without any shoulder work.' He evidently did not anticipate any great results from my engineering education.
