THE DEVELOPMENT AND PROGRESS OF HNGINEERING DUR- 
ING THE LAST TWENTY-ONE YEARS. 
In steam engineering the finest examples of modern 
steam engines to-day are to be seen in the mail steamers 
which run from New York to Great Britain and Hurope, 
and also in the large power plants of America and Europe, 
where they are arranged to drive electrical generators. 
Various examples of modern engines were briefly described. 
The use of steam jackets, re-heaters, and superheating 
apparatus for reduction of cylinder condensation was briefly 
referred to, also the modern tendency in the use of auxiliary 
engines, large units, economisers in the flues, high chimneys, 
automatic stokers supplied with coal handling machinery. 
By far the most important improvement of recent years 
in steam engineering is the development of the steam tur- 
bine, which is chiefly due to the Hon. C. A. Parsons. The 
chronology of the turbine was referred to, and the tendency 
of modern development in simplicity, steam economy and 
speed. The advantages of steam turbines over reciprocat- 
ing engines was fully considered. The steam engine has 
through nearly two centuries of continued improvement 
reached the zenith of its career of usefulness, and is in 
danger of displacement by-either one or both of its two 
thermodynamic superiors, the steam turbine and the gas 
engine. 
Steam Boilers.—Recent progress in this branch was 
referred to, and the tendency in the use of water tube 
boilers both on land and at sea. The advantages in the use 
of oil fuel were briefly considered.
