Other people go places and do pleasant things," said Margaret, her breast rising and falling stormily; "but nothing ever happens to us except broken arms, and bills, and boilers bursting, and chicken-pox!
His discovery of the true method of preventing the tendency of tubes to collapse, by dividing the flues of long boilers into short lengths by means of stiffening rings, arising out of the same investigation, was one of the valuable results of his minute study of the subject; and is calculated to be of essential value in the manufacturing districts by diminishing the chances of boiler explosions, and saving the lamentable loss of life which has during the last twenty years been occasioned by the malconstruction of boilers.
The policeman, left to himself, lost himself in the labyrinth of the basement. He made his way at last into the warm and agreeable room in which are kept the boilers that drive the engine that works the lifts. He was accosted by a stalwart stoker, whose appearance and air were as genial as the atmosphere of his apartment. "Hallo!" said he, "what 'ave you got there?"

A dozen of them were lounging about the brick-paved space in front of the battery of boilers when Bannon opened the door, and they sprang to their feet as they read his errand in his face. "Steam up," he said. "We'll be ready as soon as you are." There was the accumulated tension of a week of inactivity behind these men, and the effect of Bannon's words was galvanic.
"Stir up the fires, lads," cried the chief engineer to his men at the boilers beneath, as he stood holding a fire-nozzle ready. Intensified yells all round told that chemical action had not been applied in vain, while the pirates who had gained the bulwarks were met with streams of boiling water in their faces.
"Now, young gentlemen," resumed the chief water tender, "take your shovels and fill in lively under boilers B and D." Three or four times Heistand checked one or another of the midshipmen, to show him a more correct way of handling the shovel. Yet, in good time, both furnaces were primed. "Now, Mr.
