The first serious introduction of steam-vessels into the Royal Navy occurred about the year 1829, the Navy List of that year showing seven, of which three only were commissioned, and these for home ports. No mention is made of engineers; they were simply taken over from the contractor with the vessel, and held no rank whatever. In 1837 an Admiralty Circular conferred warrants on engineers, _who were to rank immediately below __carpenters_; they were to be assisted by boys, trained by themselves. Three years later, the standard was raised, and they were divided into three classes; in 1842 a slight increase of pay was given, and they were advanced to the magnificent rank of “after captains’ clerks,” and were given a uniform, with buttons having a steam-engine embossed upon them. In 1847 the Government found that the increasing demands of the merchant and passenger service took all the best men (the engineers’ pay, to-day, is better on first-class steamship lines than in the Navy), and they were forced to do something. The higher grades were formed into chief engineers, and they were raised to the rank of commissioned officers, taking their place after masters. The first great revolution in regard to the use of steam in the Royal Navy took place in 1849, by means of the screw-propeller. In that year Dupuy Delorme constructed the _Napoleon_, a screw-vessel carrying 100 guns, and with engines of 600 horse-power, and England had to follow. Then came the Russian War, the construction of ironclad batteries, and finally, the ironclad movement, which commenced in England in 1858, by the construction of the _Warrior_ and similar vessels. It becomes a particularly serious question, at the present time, whether the system, as regards the rank and pay of engineers, does not deter the most competent men from entering the Royal Navy. Many very serious explosions and accidents have occurred on board ironclads, which would seem to indicate that our great commercial steamship lines are far better engineered. The Admiralty has organised a system for training students at the dockyard factories, followed up by a course of study at the Naval College, Greenwich; and it is to be hoped that these efforts will lead to greater efficiency in the service. A naval engineer of the present day needs to be a man of liberal education, and of considerable scientific knowledge, both theoretical and practical, and he should then receive on board that recognition which his talents would command ashore. At present, a chief engineer, R.N., ranks with a commander, and other engineers with lieutenants. It is probable that, at some date in the not very distant future, higher ranks will be thrown open to the engineer, as his importance on board is steadily increasing.
