"Give me the gems," Balmayne said doggedly. "Everything depends upon you doing what I tell you now. Besides, we shall get them back again. By sheer force of circumstances the tables have been turned in Maitrank's favour. Give me the gems!"
FORE:The keynote of the whole poem is struck in its opening lines. When Venus is addressed as Natures sole guide and ruler, this, from the poets own point of view, is not true of Nature as a whole, but it is eminently true of life, whether we identify Venus with the passion through which living things are continually regenerated, or with the pleasure which is their perpetual motive and their only good. And it is equally appropriate, equally characteristic of a consummate artist, that the interest of the work should culminate in a description of107 this same passion, no longer as the source of life, but as its last outcome and full flower, yet also, when pushed to excess, the illusion by which it is most utterly disappointed and undone; and that the whole should conclude with a description of death, not as exemplified in any individual tragedy, but in such havoc as was wrought by the famous plague at Athens on man and beast alike. Again, it is by the orderly sequence of vital phenomena that Lucretius proves his first great principle, the everlasting duration and changelessness of matter. If something can come out of nothing, he asks us, why is the production of all living things attached to certain conditions of place and season and parentage, according to their several kinds? Or if a decrease in the total sum of existence be possible, whence comes the inexhaustible supply of materials needed for the continual regeneration, growth, and nourishment of animal life? It is because our senses cannot detect the particles of matter by whose withdrawal visible objects gradually waste away that the existence of extremely minute atoms is assumed; and, so far, there is also a reference to inorganic bodies; but the porosity of matter is proved by the interstitial absorption of food and the searching penetration of cold; while the necessity of a vacuum is established by the ability of fish to move through the opposing stream. The generic differences supposed to exist among the atoms are inferred from the distinctions separating not only one animal species from another, but each individual from all others of the same species. The deflection of the atoms from the line of perpendicular descent is established by the existence of human free-will. So also, the analysis which distinguishes three determinate elements in the composition of the soul finds its justification in the diverse characters of animalsthe fierceness of the lion, the placidity of the ox, and the timorousness of the deerqualities arising from the preponderance of a fiery, an a?rial, and a windy ingredient in the animating principle of each respectively. Finally, by another organic108 illustration, the atoms in general are spoken of as semina rerumseeds of things.Were this intellectual despondency to issue in a permanent suspense of judgment, it would be bad enough; but practically its consequences are of a much more mischievous character. The human mind is so constituted that it must either go forward or fall back; in no case can it stand still. Accordingly, the lazy sceptic almost always ends by conforming to the established creeds and customs of his age or of the society in which he lives; thus strengthening the hands of authority in its conflict with the more energetic or courageous enquirers, whose object is to discover, by the unaided efforts of reason, some new and positive principle either of action or of belief. And the guardians of orthodoxy are so well aware of the profit to be reaped from this alliance that, when debarred from putting down their opponents by law or by public opinion, they anxiously foster false scepticism where it is already rampant, and endeavour to create it where it does not exist. Sometimes disinterested morality is the object of their attack, and at other times the foundations of inductive science. Their favourite formula is that whatever objections may be urged against their own doctrines, others equally strong may be urged against the results of free thought; whereas the truth is that such objections, being applicable to all systems alike, exactly balance one another, leaving the special arguments against irrationalism to tell with as much force as before. And they also lay great stress on the internal dissensions of their assailantsdissensions which only bring out into more vivid relief the one point on which all are agreed, that, whatever else may be true, the traditional opinions are demonstrably false.
THREE:Slowly, almost in a graveyard glide, so flat was the descent, to hold flying speed and stay as high as they could, their airplane moved along. They listened.Questions and answers constitute the principal medium for acquiring technical information, and engineering apprentices should carefully study the philosophy of questions and answers, just as he does the principles of machinery. Without the art of questioning but slow progress will be made in learning shop manipulation. A proper question is one which the person asked will understand, and the answer be understood when it is given; not an easy rule, but a correct one. The main point is to consider questions before they are asked; make them relevant to the work in hand, and not too many. To ask frequent questions, is to convey an impression that the answers are not considered, an inference which is certainly a fair one, if the questions relate to a subject demanding some consideration. If a man is asked one minute what diametrical pitch means, and the next minute how much cast iron shrinks in cooling, he is very apt to be disgusted, and think the second question not worth answering.
FORE:
A learner is apt to reverse this proposition at the beginning, and place time before skill, but if he will note what passes around him, it will be seen that criticism is always first directed to the character of work performed. A manager does not ask a workman how long a time was consumed in preparing a piece of work until its character has been passed upon; in short, the quality of work is its mechanical standard, and the time consumed in preparing work is its commercial standard. A job is never properly done when the workman who performed it can see faults, and in machine fitting, as a rule, the best skill that can be applied is no more than the conditions call for; so that the first thing to be learned is to perform work well, and afterwards to perform it rapidly.Opposed to the maintenance of standard dimensions are the variations in size due to temperature. This difficulty applies alike to gauging implements and to parts that are to be tested; yet in this, as in nearly every phenomenon connected with matter, we have succeeded in turning it to some useful purpose. Bands of iron, such as the tires of wheels when heated, can be 'shrunk' on, and a compressive force and security attained, which would be impossible by forcing the parts together both at the same temperature. Shrinking has, however, been almost entirely abandoned for such joints as can be accurately fitted.
