PRACTICAL TREATISE

ON

LOCOMOTIVE ENGINES;

A WORK INTENDED

TO SHOW THE CONSTRUCTION, THE MODE OF ACTING, AND THE USE OF
THOSE ENGINES FOR CONVEYING HEAVY LOADS ON RAILWAYS; TO GIVE
THE MEANS OF ASCERTAINING, ON AN INSPECTION OF THE MACHINE,
THE VELOCITY WITH WHICH IT WILL DRAW A GIVEN LOAD, AND THE
EFFECTS IT WILL PRODuce under VARIOUS CIRCUMSTANCES; TO DETER-
MINE THE QUANTITY OF FUEL AND WATER IT WILL REQUIRE; TO FIX
THE PROPORTIONS IT OUGHT TO HAVE, IN ORDER TO ANSWER ANY IN-
TENDED PURPOSE; ETC.

FOUNDED ON

A GREAT MANY NEW EXPERIMENTS,

MADE ON A LARGE SCALE, IN A DAILY PRACTICE, ON THE LIVERPOOL AND MAN-
CHESTER, AND OTHER RAILWAYS, WITH MANY DIFFERENT ENGINES, AND
CONSIDERABLE TRAINS OF CARRIAGES.

TO WHICH IS ADDED,

AN APPENDIX;

SHOWING THE EXPENSE OF CONVEYING GOODS, BY LOCOMOTIVE ENGINES,
ON RAILROADS.

INTRODUCTION

TO THE FIRST EDITION.

THERE exists no special work on locomotive engines. Two writers, Wood and Tredgold,' have indeed, in England, slightly touched upon that matter, but only in a subordinate manner, in treatises on railways; and, besides, they both wrote at a time when the art was scarcely beyond its birth. Consequently their ideas, their calculations, and even the experiments they describe, have hardly any relation to the facts which actually pass before our eyes, and can be of no use to such as wish to acquire a knowledge of these engines and their employ on railways.

Many questions had not even been entered into, others had been solved in a faulty manner. New researches on the subject became therefore indispensable. This work will, in consequence, be found completely different from

1 'A Practical Treatise on Railroads, and Interior Communication in general, by Nicholas Wood.' 1st edition, London, 1825; 2d edition, London, 1832.

A Practical Treatise on Railroads and Carriages, by Thomas Tredgold.' London, 1825.
