139"Lytton Avenue houses are large and they have gardens."
ONE:"This looks like business," Prout exclaimed. "The letter is not sealed. Anyway, it was written here with the pen on the mantelpiece and that penny bottle of ink; see how pale it is and what shabby paper, evidently a ha'porth purchased from some huckster's shop. Isn't that right, sir?"
Success in Technical Training, as in other kinds of education, must depend greatly upon how well the general mode of thought among learners is understood and followed; and if the present work directs some attention to this matter it will not fail to add something to those influences which tend to build up our industrial interests.In no other branch of machinery has so much research and experiment been made during eighty years past as in steam machinery, and, strange to say, the greater part of this research has been directed to the details of engines; yet there has been no improvement made during the time which has effected any considerable saving of heat or expense. The steam-engines of fifty years ago, considered as steam-using machines, utilised nearly the same proportion of the energy or power developed by the boiler as the most improved engines of modern constructiona fact that in itself indicates that an engine is not the vital part of steam machinery. There is not the least doubt that if the efforts to improve steam-engines had been mainly directed to economising heat and increasing the evaporative power of boilers, much more would have been accomplished with the same amount of research. This remark, however, does not apply to the present day, when the principles of steam-power are so well understood, and when heat is recognised as the proper element to deal with in attempts to diminish the expense of power. There is, of course, various degrees of economy in steam-using as well as in steam-generating machinery; but so long as the best steam machinery does not utilise but one-tenth or one-fifteenth part of the heat represented in the fuel burned, there need be no question as to the point where improvements in such machinery should be mainly directed."Dead," whispered Prout, "dead instantly. It was prussic acid. The whole room reeks of it. Perhaps it was as well to finish it this way. There'll be an inquest now, and the whole business will come out.""Inevitably. But you were not in a book, unfortunately. You were flesh and blood and you took your own way. You thought you had been slighted. You made up your mind to get your revenge at any price. All the same, you could not see your way. You wanted a neat plot to get Bruce into trouble, for he had bad taste in not caring for you. You used the simple expedient of stealing mine."
