Excerpt from Hints on Steam-Engine Design and Construction: With Practical Suggestions

Introduction. - In engineering, experience is the knowledge of the behaviour of certain contrivances in actual working, and a just estimation of the difference between the result anticipated by theory and that realised in practice. It is knowledge gained by the observation and comparison of many conditions, and is perhaps to be most rapidly attained by a study of failures. To a genius it may not be essential, but an ordinary man gets his living with it.

The writer has often thought what a valuable work might he written by any successful engineer, if he had only the courage to give us a record of all his mistakes, his erroneous notions, and his ignorance. We should see how he started with very limited knowledge, how he groped in the dark, yet was continually gaining wisdom, and applying it to the work he had in hand. We could follow the working of his mind, and trace the considerations which guided him in carrying out his successful undertakings. The work would be as interesting to engineers as the diary of Mr. Samuel Pepys is to the student of literature and history. But perhaps it is too much to expect such a book. If an engineer kept such a diary ho would probably leave instructions in his will that it should be burnt; or, bequeathing it to his son, it would be looked upon very much in the same light as the life of Dr. Johnson was regarded by the son of that illustrious biographer.
