"Mr. FIDLER'S SUCCESS arises from the combination of EXPERIENCE and SIMPLICITY OF TREATMENT displayed on every page. Theory is kept in subordination to practice, and his book is, therefore, as useful to girder-makers as to students of Bridge Construction."-("The Architect" on the Second Edition.) "Of late years the American treatises on Practical and Applied Mechanics have taken the lead . . since the opening up of a vast continent has given the American engineer a number of new bridge-problems to solve but we look to the PRESENT TREATISE ON BRIDGE-CONSTRUCTION, and the Forth Bridge, to bring us to the front again."-Engineer.
