In the sale of former editions of this work, it has been found that its success has been largely due to its value as a book of design. Great attention has therefore been given to secure practical illustration of constructions and machines of recent date; the nature of materials in common use has been more extensively treated, and the character and effect of stresses and strains, their kind and direction, more fully explained, with as simple rules as possible to determine them for practical application.

Of late years the science of graphics has become of great importance, and is here fully illustrated in its varied applications, showing not only this method of recording the facts of the statistician, and affording comparisons of circumstances and times, the growth of population, the quantities and cost of agricultural and mechanical production, and of their transport, movements of trade, fluctuations of value, the atmospheric conditions, death-rates, etc., but also in its application to the plotting of formulae for their ready solution, by the draughtsman and designer. For many of the rules in this work the results of the formulae of various authors have been plotted graphically, and the rule given one deemed of the greatest weight, not always by average, but most consistent with our own experience.
