THREE:The woman was smiling now quite freely. All traces of passion and anxiety were gone. She knew the end had come, and she was prepared to accept it without complaint. Prout looked a little awkward as he bowed.152

THREE:CHAPTER III

THREE:Engines operated by means of hot air, called caloric engines, and engines operated by gas, or explosive substances, all act substantially upon the same general principles as steam-engines; the greatest distinction being between those engines wherein the generation of heat is by the combustion of fuel, and those wherein heat and expansion are produced by chemical action. With the exception of a limited number of caloric or air engines, steam machinery comprises nearly all expansive engines that are employed at this day for motive-power; and it may be safely assumed that a person who has mastered the general principles of steam-engines will find no trouble in analysing and understanding any machinery acting from expansion due to heat, whether air, gas, or explosive agents be employed.

THREE:I now come to note a matter in connection with draughting to which the attention of learners is earnestly called, and which, if neglected, all else will be useless. I allude to indigestion, and its resultant evils. All sedentary pursuits more or less give rise to this trouble, but none of them so much as draughting. Every condition to promote this derangement exists. When the muscles are at rest, circulation is slow, the mind is intensely occupied, robbing the stomach of its blood and vitality, and, worse than all, the mechanical action of the stomach is usually arrested by leaning over the edge of a board. It is regretted that no good rule can be given to avoid this danger. One who understands the evil may in a degree avert it by applying some of the logic which has been recommended in the study of mechanics. If anything tends to induce indigestion, its opposite tends the other way, and may arrest it; if stooping over a board interferes with the action of the digestive organs, leaning back does the opposite; it is therefore best to have a desk as high as possible, stand when at work, and cultivate a constant habit of straightening up and throwing the shoulders back, and if possible, take brief intervals of vigorous exercise. Like rating the horse-power of a steam-engine, by multiplying the force into the velocity, the capacity of a man can be estimated by multiplying his mental acquirements into his vitality.And the how and the why.

THREE:In this grand old monastery, both inside and out a jewel of architecture, about five hundred people had found shelter. They were lodged in halls, rooms, and kitchens. The fathers gave them everything in the way of food they might require, but they had to do their own cooking. As not one of these people had a home left, which they could call their own, no wonder that they greatly admired the fathers. Often when I strolled about with one of these, one or other of the refugees came to him to press his hand and express gratitude for the hospitality offered.

THREE:"In the breast pocket of my inner coat. Bah, why argue over it?"The beautiful part of it, to Sandy, was that he could sit by and watch, do nothing, except ��pay out rope and let them tie themselves up in it.��
