Although regarding the training and discipline of firemen as of the first importance in the organization of a fire brigade, Mr. Braidwood gave a large share of attention to the improvement of fire-engines and their kindred appliances. While in Edinburgh, where the steepness of many of the streets, and the roughness of the pavements in the older parts of the town prevented the rapid and easy movement of heavy engines, he recommended and adopted a lighter description, but in London he recognised the necessity for greater power. Mr. Tilley, then a fire-engine maker in the Blackfriars'-road, ably seconded his efforts, and at length the distinctive type known as the London Fire Brigade Engine was produced, and which, weighing about eighteen cwt. when ready for service, would throw eighty-eight gallons of water per minute, and, in short trials, as much as 120 gallons in the same time. This engine was mounted upon springs, and in strength and ease of working presented a marked improvement upon those which had preceded it. Its ordinary working complement of men was twenty-eight, and larger engines, upon the same general design, have since been made, to be worked by from forty-five to sixty men. The steam fire-engine has already, to a certain extent, superseded the brigade engine, but the latter is still likely, for some time at least, to be preferred for a large class of fires, both in London and in the provinces. Mr. Braidwood at an early date adopted the ordinary military scaling ladders to the purposes of his brigade, two being placed on each engine, and at his recommendation ladders were also placed on a two-wheeled carriage as a convenient fire-escape. He also induced the Admiralty, in 1841, to adopt hose-reels in the various dockyards, these implements having been previously in successful use in New York. In 1848 he was induced, in consequence of the large number of small fires to which his engines were called out, to adopt a small hand-pump as an auxiliary to the fire-engine. This could be rapidly brought to bear, and although worked by but one man, the value of a small quantity of water thrown directly upon the seat of a small fire was found to be greater than that of perhaps twenty times as much when thrown about in the ordinary manner. It was of great importance also in warehouses stored with valuable goods, to throw the least necessary quantity of water upon a fire. These hand-pumps still form an important part of the present apparatus of the brigade, and they have been widely adopted elsewhere.
